The purpose of this thread is to document the modifications on my 2013 Nissan 370Z GT Edition (M/T, MY12) that will culminate in an aam Twin Turbo conversion. It will in itself be a first-of-its-kind: my car serves as test vehicle for TORQEN to modify and fit the prestigious AAM TT kit to a RHD 370Z. The conversion should be completed by winter.

- Motordyne Shockwave))) with optional full dual-3" [#0004]

 

* These are upgrades I've already done in the past, while the TT kit and remaining upgrades are sitting in my home ready for installation.

 

With Torqen not yet quite ready for my install I decided to test-fit the FMIC and modify my Amuse front bumper as needed. The modifications required turned out to be a little more extensive than I assumed and I am glad I've been working away on that issue, which will be saving Adrian some precious time later on. Here are the details.

 

According to the AAM TT kit install guide the front end should look like this:

AAM%20FIC%20fit.jpg

 

Tweak #1

The top of the FMIC is attached to the two hood lock brackets where the two horns are bolted onto. As advised by the manual, the horns need to be bent backwards in an S-shape to create enough clearance for the FMIC. But those bolts have hardly enough spare thread to accommodate the beefy FMIC top mounts. And because those bolds are welded to the brackets they cannot be swapped for longer ones. One side of these mounting points was crimped (presumably an alignment guide for the horns), which I simply filed off/sawed off. Now the FMIC top mounts lie flush against the bracket and the bolts have enough remaining thread.

FMIC_1.jpg

 

Tweak #2

Also, AAM intends to relocate the stock P/S cooler and mount it vertically to the right hand side of the FMIC via two mounts welded to the FMIC core. This mod does not work on my car! My stock P/S cooler is much longer than the pictured P/S cooler on AAM's test car. The FMIC cooler mounts will not accept my stock P/S cooler. I have been searching for alternatives and found the perfect mounting place. The stock location! Albeit, the cooler is too far forward to sandwich between FMIC and radiator. So I fabricated mounting brackets that resemble the stock brackets but move the P/S cooler closer to the radiator by 45mm. Note, I needed to trim a little bit of plastic from the radiator core support. Now the P/S sits snug between FMIC and condenser.

FMIC_2.jpg

FMIC_3.jpg

As we can see, I've already re-routed the P/S hoses as per install guide. Because, the stock cooler hoses were routed around the bottom left corner of the radiator core support but that's where the intake charge pipe from the FMIC is going to go round.

However, I chose a slightly different route than the install guide. Firstly, AAM routes the hoses past the crash bar mount, but that's where my external oil cooler hoses pass through already. Thus I routed the P/S cooler hoses slightly below and in between the two washer reservoir mounts. Secondly, AAM replaces the top hose all the way up to the P/S fluid reservoir with a new rubber hose, whereas I deliberately re-used the stock hard pipes (after some trimming) so the P/S pipes remain secured to the stock mounting point. See below:

FMIC_4.jpg

 

Tweak #3

The install guide does not account for any external oil cooler. Due to the FMIC position my oil cooler needs to find a new location. I found people mounting theirs to the left or right side of the crash bar, in front of the wheel well. But my Amuse front bumper won't supply this area with any air. Alternatively, people bolt the oil cooler onto the underside of the crash bar. Unfortunately this only works for small 19 row coolers, my 25 row cooler is too tall. I might have cut half way into the crash bar, reducing its height, to give me the missing 4cm height clearance. But then the FMIC would be partially blocked, probably unevenly, considering the FMIC is internally split in two, one for each turbo. I read an ideal arrangement should stack like this: Air -> FMIC - > Oil cooler -> Condenser/Radiator. Hence, I was determined to squeeze the oil cooler into the gap between FMIC and condenser (where my P/S cooler already resides). With a cooler core thickness of 2 inch that's tricky, given the fact that I sport the significantly thicker Mishimoto radiator. Stock radiator would've been easy. But it's not impossible! I figured the FMIC needs to come forward by about 14mm. So I increased the two 19mm M8 spacers (see below) that come with the TT kit to 33mm, as well as, use longer bolts.

FMIC_5.jpg

This will increase the gap between FMIC and condenser to about 57mm - enough to harbour my 2" thick oil cooler. But for this to work the crash bar needs to come slightly forward, too, to allow the FMIC to come forward by said 14mm. Using 4mm thick M8 washers where the crash bar bolts to the car, as well as, filing away a small amount of material from the inside does the trick. See below:

FMIC_6.jpg

FMIC_7.jpg

Back to the oil cooler. I re-installed it pretty much exactly where I've had it mounted before (default Z1 Motorsports install location). Except, I am moving the cooler as close to the condenser/radiator as possible (just millimetres away) using 15mm long M6 spacers for the two lower mounting bolts. Because of this slight relocation the left oil inlet port now interferes with the hood lock stay assembly (vertical centre bracket with the temperature sensor on it). But it's safe to cut a bit into this, structurally speaking. This is how it looks now:

FMIC_8.jpg

 

Finally the FMIC can go back on, neatly sandwiching the P/S and oil coolers.

FMIC_9.jpg

 

Tweak #4

The Amuse front bumper needed minor trimming to accommodate the new FMIC.

Thanks all, should become something great :stir:

Right now I am enjoying a few holidays. Back this Friday. It's only been 1 day and I already can't wait to get back under my car :lol:

 

Have a good weekend!

With Torqen currently anticipating work on an AAM TT 350Z HR, I thought I'm gonna gap the time with detailing some of my other mods.

 

I bought my pearl white 370Z GT Edition in Sept 2013 as an ex-demo car with an age of a mere 6 months and hardly 6000 miles on the clock. Got a significant discount for her being virtually new :)

post-22961-0-76615500-1439217059_thumb.jpg

What I loved from the moment I saw her for the first time is the pearl effect shimmer with the contrasting gloss anthracite alloys with that gorgeous design and the rumbling transmission noise filling the cabin at low speeds. I likened it a little to the way the GTR feels when I test drove one (gently). The GTR was my initial choice for its all out performance but the price tag made me quickly look at the Z... and I never looked back. In terms of looks the Z wins 3x over and in terms of performance I already decided to F.I. it one day.

What I didn't like on the stock Z were the super quiet exhaust that nowhere near complements its potent engine, the unsightly front and rear bumpers and the empty wheel arches - all of which I was about to remedy first thing :stir:

 

So i had Abbey Motorsport order me the Motordyne Shockwave))) 2.5-3" hybrid exhaust with tuned Helmholtz resonators because I was aiming to create a rather screaming yet not droning exhaust note (blame my nitrous infused VTEC blasts from the past :p ).

Also, I had Bulletproof Automotive order me Amuse Powerhouse Vestito bumpers, which took a good while to ship from Japan to Los Angelas, to U.K. in an effort to greatly reduce shipping costs.. huh? :lol:

 

Meanwhile I got busy with tinting the tail lights with a can of VHT Nite-Shades Black [#SP999].

post-22961-0-65604700-1439218969_thumb.jpg

and, inspired by ONEighty° on the370z.com forum, blacked out my head lights and added orbs (a.k.a. angel eyes).

post-22961-0-00376600-1439219233_thumb.jpg

For the matte black paint I got myself a can of Krylon Fusion flat black [#KO2519], which after some research to my knowledge is the only way to do it right (primer-less plastic paint). But it's hard to come by her in the U.K. I sourced mine from here.

The orbs I've sourced from Luce Produkt Innovations, which is where ONEighty gets theirs from, but the page seems to be down. You can get them directly from them now [LED Orb rings].

I added some innovation to the LED Orbs, though: a home-made controller to switch them on the dashboard with a visually suiting orb-style S/S push button :D

Angel%20Eyes%20Controller.jpg

My circuit for the so-called Debounced Flip-Flop Switch is below. Black drawings are inside the "black box" stowed underneath the dashboard, grey drawings route to the LED orbs, and pink drawings are vertical LED DRLs powered in parallel to the Orbs that I added later onto my Amuse front bumper.

At that point my Z looked like this, with my Mrs inside B)

Now that I already mentioned front bumper mods I go straigh to the yummie body kit parts. :teeth:

I didn't want to go for the full Amuse Vestito Aero kit but instead combine the front [#AMUSE370Z13] and rear [#AMUSE370Z15] bumpers with a NISMO wing, albeit for cost reasons not the genuine part but made by EVO-R and sold by theZstore [#50-1885]. Also, I wanted it painted exactly the way theZstore advertised it, it looks exceptional.

Got my parts painted locally and fitted everything at home. I documented the install over here already. The side skirts I wrapped in 3M Di-Noc Black Carbon [#CA-421] with the help of some 3M Primer 94 adhesion promoter, a heat gun and the second pair of my wife's hands ;)

post-22961-0-85367200-1439222919_thumb.jpgpost-22961-0-24690100-1439222940_thumb.jpgpost-22961-0-43465500-1439222623_thumb.jpgpost-22961-0-48267700-1439223011_thumb.jpg

The front bumper, though, I customized with the addition of said DRLs. I went for the HQ Auto Lighting #DRL-HQ-V12 (bought though Ebay) because of their excellent quality and truly brilliant light output - no flimsy glow á la Halfords but OEM style brightness (6-LED Cree, 2x6W, 2x600LM, 6500K).

Secondly, I added home-made skid plates cut from 3mm aluminium and Hammerite Metal painted (aluminium color). And with that little addition of a racing tow hook for that little cheeky look :p (painted in lime green, just like my brake calipers)

Skidplates.jpg

Amuse3.jpg

Amuse4.jpg

Quarter.jpg

Side.jpg

Whereas the rear bumper I customized with a Formula 1-style flashing brake light. I replaced our stock fog light with the EVO-R Flashing LED Rear Foglight [#50-3084 Smoked]. Once wired in it would fully light up when "fog light" is switched on and flashes even brighter when pushing the brake pedal (the install sheet destribes how to route a wire from the rear brake light to the second input). For the fog light operation an 18Ohm 50Watt power resistor is needed or else the ECU will strike.

Now, I did however brake open my EVO-R light and de-soldered all LEDs. Why? I wanted brighter LEDs :stir: So I soldered in 42x 2200 mCd 70° Hi Bright LEDs. But I had to re-adjust the drive currents for the new LEDs. For this I had to first reverse-engineer the circuit board in order then to calculate replacement resistors. No big deal for a physicist, it ain't rocket science :lol: For the interested, the amendments are here.

Above pics also include tinted rear, quarter and side windows.

Again I considered 3M but decided for the better priced and good quality The Black Box Tint Alpine Seriesâ„¢ Automotive Window Film, which come computer pre-cut. I used this tint chart as guide and also considered the law (having been pulled over in the past by tinted side windows)

First thing i did was measure the factor tint of the 370Z with a Lux meter. My data on the glass transmissions:

windshield ~85%

side windows ~75%

quarter windows ~85%

rear window ~85%

 

The law limits are:

windshield min. 75%

side windows min. 70%

 

I wanted the Rear and Quarters tint rather dark when seen from the outside but still easily see-though from the inside. Thus, I picked 20% VLT. Theoretically the result should be 0.85*0.2=17% overall transmission. I estimated 12% with the lux meter.

For the side windows I could legally not have added any tint.. pfff, come on!

So I picked the lightest tint available: 50% VLT. Theoretically I should yield 0.75*0.5=38% overall transmission. But I measured 61%, and I think that's a great outcome - legally speaking :)

What other exterior mods have I done:

 

LED for Bulb swaps all-round including ballast resistors where needed. Can all be found my webpage.

 

Painted calipers in gloss Lime green using E-Tech Brake Caliper Paint [#EBCP-GR]. As many do, I did decide for a color theme for my Z, which is white | black/carbon | lime green. I removed the calipers for the paint job and when I put the back on and refilled the brake fluid I came to a point of near despair coz I couldnt get the pedal firm yet didn't see any remaining air trapped.. until i realized this car got bleeders on the front AND on the bloody back of each caliper! :rant: LOOL. Well, end good all good.

I kinda regret I put Brembo stickers on them, but come next chance I replace them with actual Akebono :blush:

Caliper2.jpg

 

Then there are my beloved home-made Gas Strut Bonnet Props :D

I did some calculations to estimate angles and forces on the bonnet after I decided mounting points. Then i bought a pair of Nitrider® Gas Struts [#W06JAS0350] with following parameters:

Tube∅: 15 mm

Rod∅: 6 mm

Stroke: 150 mm

Total lenth: 366 mm

Load: 350 N

End fittings: Welded eyes

I made a pair of mounting brackets from S/S. Et voilà! Sweet as hell :teeth:

Note, some cutting into the plastic trim is needed.

More descriptions another day.. BBQ is waiting :lol:

It may be too early in the morning for me, but am I reading that correctly that you've now made the side windows illegal, despite having been pulled for this before?

 

Great thread btw, I like how you've broken down all the steps and given annotated photos to show the engineering difficulties and how you've overcome them :thumbs:

ROFL......I saw that bit about the tints started scrolling and thought 'aaaany second now, aaaaany second now' then viola there you were :lol:

LOL, you are absolutely right, technically my tint is not legal. But i said I'd consider the law, not adhere to it :p

What it is, I used to be pulled over coz i had my side window tinted way too dark, perhaps 30% total transmission. No way the officer would have let me off the hook. But now at 61% it looks borderline Luxury class OEM and in dayline the tint is not dark enough to draw attention to the law and cause suspicion, IMO. A police officer can hardly tell 61% from 70% by naked eye to have reason for a check. So, I am prepared to risk it this time :surrender:

Thanks, yup, will carry on :thumbs:

 

A few words to my current exhaust setup.The Motordyne Shockwave))) [#0004] was soon coming through from Abbey Motorsports and already went on before the body kit.This is the exhaust with some dimension verification. The Y-pipe is 2.5" and the rest is 3". Total weight 26.36 kg.Motordyne_1.jpgMotordyne_2.jpgMotordyne_3.jpg

I swapped the default blue-burnt Ti tips with IMO much more beautiful 42 Draft Designs brushed S/S double-wall tips [#EX-91-62CBR]ExhTips.jpgThe exhaust currently mates to a pair of non-resonated metallic core Berk HFCs (2.5", 200-cell) [#BT1407-HFC-MET]. Each HFC weighs 2.7 kg vs. stock 5.1 kg.But with my AAM TT kit the Berks will become obsolete. The kit comes with 3" downpipes with HFCs. A.t.m. AAM added me 400cell cores into the downpipes but am considering a swap for 200cells before of the install approaches. Would help gas flow and should still pass emissions test. If not I'll have to find a friendly M.O.T. :lol

But I will also have to upgrade my 2,5" Y-pipe to fit the future 3" downpipes. Tony@Motordyne told me they are currently developing a full 3" Shockwave))). Estimated lead time 3 months. It should be available just in time for my TT install ;)

 

The intake upgrades comprise a popular Stillen Generation 3 Ultra Long CAI [#402852], dry filter version (which doesn't need regular oiling). Added Z1 Motorsports Silicone Side PCV Breather Hoses [set] and wrapped in Mishimoto Gold heat reflective tape [#MMGRT-235]. Naturally, this pretty intake got to go soon, too.

CAI3.jpg

The CAI is complimented with a Z1 Motorsports modified intake plenum [#7267]. For this Z1 takes a stock i/plenum and sands and files the inside surface slightly. I compared my stock and the Z1 i/plenum side by side. The differences appear minute, IMO; the surface is roughened. Still, it's part of their 400 bhp kit. Fortunately it is compatible with the TT kit, though, in a boosted setup the power gain will become nil.Intake.jpg

At the same time I swapped the heavy stock crank pulley for a Stillen Lightweight crank pulley [#400338-01] made from CNC machined Billet 6061 aluminum and 304 S/S sleeves. Weight 600 g vs stock 2.14 kg. The reduced inertia recovers some otherwise lost HP. The install was "relatively" simple. Once the radiator fans were removed I had good access to the belt and crank pulley. The hardest was unbolting and re-bolting the crank pulley. That SOB sits so bloody tight you keep thinking something is gonna snap any moment, either the breaker bar or the bolt or both. I used a long 1/2" ratchet (had no proper breaker bar) and extended it with a long alu pipe. I stood with my feet against the garage wall and pushed the crap out of it. The rear end of the car started to lift off :scare: It is quite something to do. lol

 

Inertia will be further reduced with my CompetitionClutch clutch [#6073-2100] and lightweight flywheel [#2-630-6ST] mentioned in the first post. The weight reductions will be:CC clutch 7.2 kg vs stock 8.6 kgCC flywheel 8.0 kg vs stock 14.5 kgI was conscious not to choose a too light flywheel, which will cause noisy rattling. Hence I decided for CC's 4140 forged steel flywheel with the added benefit of being much stronger than an aluminium flywheel (which will be fine for NA applications).

Now onto some dashboard enhancers and gadgets.

 

I thought a lot about where to mount any additional gauges to the dashboard. After all, the SatNav area is occupied. I thought I could fit two gauges at either side of the instrument panel roof as long as it's done nicely :)

So I went for two all-metal 52mm GlowShift Gauge Pods [#GS-U01B].

Into one I fitted an AEM Wideband UEGO AFR gauge [#30-4110], which features the latest Bosch LSU 4.9 sensor. This will keep track of my A/F ratios once boosted :thumbs:

I realise the 370Z comes stock with two wideband AFR sensors called A/F sensor 1 in the Service Manual.

But I'm not aware of many aftermarket products offering a direct read-out of these.

MAP5.jpg

The AEM UEGO sits in the left hand side pod. The right-hand side pod houses something unique I will come back to in a moment ;)

I also have a GReddy Infometer-TOUCH [#16001604], which is an engine monitor and diagnostic tool with touch screen, attached to the right side of the windscreen.

Just above it on the windscreen sits my brand new GReddy Profec Electronic Boost controller [#15500214]. (not in the picture) For now it's only hooked to power. I leave the routing of the data cable that runs to the boost controller in the engine compartment to Torqen, since they'll determine the exact mounting location of the controller ;)

 

The centre console is touched up with a gloss black Mishimoto weighted shift knob [#MMSK-BK]. It weighs 363 g and I absolutely love the feel in my hand :drive1

ShiftKnob.jpg

In order get the stock knob off I advised to use a rubber strap wrench. Before I tried a pipe wrench with cloth - hopeless. The stock knob sits über-tight.

 

Back to the right-hand side gauge pod. When I planned F.I. on a stock block I knew boost will be limited to roughly 8-9 psi. I went to search for the perfect 52mm Vac/Boost gauge. It had to both be accurate and high-resolution (0.1psi) since my boost numbers would be "small". To help things the total range should therefore be 10-15 psi. I searched forth and back and found none on the market. the "smallest" gauges go to 30 psi with coarse dials...

Having built many electronic gadgets for my Prelude, I thought why don't I build my very own perfect Boost gauge. No sooner said than done! :stir:

Here we go:

 

First I selected a high quality temperature compensated Bosch MAP sensor [#0 281 002 487] found in many Mercedes-Benz. It's the lowest above-atmosphere MAP for "reasonable" money I could find. No point having a 5 bar boost sensor when we want high resolution up to 10 psi. This sensor still costs over £60. It's got an absolute pressure range of 20...250 kPa (up to 1.5 bar boost). The sensor outputs a corresponding 0...5 V signal. My aim was to devise a circuit that would convert this voltage into an LCD reading of -1.0...-0.0 bar for the vacuum range, and 0.0...10.0 psi for the boost range. The resolution would thus be 0.1 bar/psi with a final accuracy of ±3%. I wanted the readout be accompanied by a 20-LED bar graph - white LEDs for Vacuum, orange LEDs for Boost.

...

Time-jumping a few months of spare time design and development, this is what I came up with :teeth:

MAP4.jpg

As gauge housing served a stripped empty Ebay gauge with smoke lens. The gauge face I drew in PowerPoint and printed on a Laser printer on clear film (eg. for overhead projectors).

Now I will be teasing (shocking?) you with what's inside :lol:

MAP2.jpg

All I need now is BOOST!
