Tiptronic GM 350z DE Build thread (pre map dyno figures)

[russyb]

So here it goes I had no plans in ever making a build thread for my 350z but as time is moving on bits are mounting up and I'd like to keep a documented post of past and future.

 

I bought our (wifes) 350z back in early December last year, now I have come from a heavily modified world of turbo charged jap motors the last being a forged TD05 starlet running 1.6bar of boost@ 310bhp ATW which I built myself ..... but we recently got married and decided to have just one weekend car instead of the 3 / 4 that we had previously so after much toing and froing the 350z came up and the deal was done.

The wife can only drive auto/tiptronic due to a hip replacement so when this bone stock 2002 350z came up i was on it. a low mileage 86,000 changed from kph @ 24,000.

 

So I had no real plans to mod just wanted gt spec rays and some hubcentric spacers and that was it.......... yeah right who the hell was I kidding lol.

 

So as said I started out with good intentions I bought the rays which came with Bridgestone Potenzas on brilliant also picked up some eibach hubcentric spacers front & rear and a RDX Stubby ... great,

 

then I got bored and missed not tinkering so did a full P3 service including plugs, diff oil etc etc, but still not enough so I started thinking UpRev remap and that was my downfall really it was a license to buy every possible N/A mod to get the most out my remap and now I can't stop ..I'll add pictures as I go along but,

current NA engine mods are;

 

Horsham Developments Plenum spacer

Horsham Developments Earthing Kit

HKS Super Hybrid Panel Filter

Velocity Stack 06 Intake Mod

Japspeed Hi-Flow custom Braced Cats

Japspeed K2 Catback Exhaust Resonator Deleted

Japspeed Y-Pipe/w enlarged custom flexi’s

Sun Auto Hyper Voltage Stabilizer

Idle Pulley Delete Mod

Rev-up Aux Belts

Magnetic Sump Plug

NGK Iridium spark plugs x 6

NRZ Engine Gunmetal Billet Oil Cap

Motordyne Throttle Body Coolant Bypass

Helix Throttle Body Spacer

Mishimoto Crankcase Catch Can Setup

Motordyne ISO Thermal Gasket Upgrade

Works Bell Paddle Shifter (imported direct from the rising sun)

 

A few choice exterior and interior mods but really its all about the business end for me

18†Forged Rays Engineering Alloys

20mm Front Hubcentric Spacers x2

25mm Rear Hubcentric Spacers x2

RDX Stubby Aerial

Late Spec Clear Bumper Reflectors

Pioneer AVH-P4300DVD Headunit

Parrot Bluetooth Device

Aluminium Interior Vent Trim

OE Parcel shelf

LED Bulb interior Upgrade

Momo Automatico Leather Shifter

USDM Rear Clear lens conversion

Correct Sized Jdm Rear Reg Plate

 

 

Not really sure about handling mods guys so advice is welcome. I'm used to fitting handling mods to “a car that was never meant to go that fast†so what doesn’t a 350z come with stock ?

 

Turns out she was a pretty good buy as only fault I've found is typical windows need a hard reset and leaky gasket cover (which is on order from Adrian).

 

I'm hoping to remap around my birthday so September time but I have a dyno day arranged by one of my best pals in a few weeks which I thought would be great to get a base reading before remap so I will post up results as and when (obviously) I know some of these mods may yield very small even unnoticeable power gains but my logic is enough small gains will mount up,

 

i have zero plans to supercharge or turbocharge her as i need a well earned break from forced induction for a while haha.

 

Thanks for reading guys I'll keep this as updated as much as possible please bear with me with pics as I have very few as I had no plans to do a build thread but hey... things change I guess hahafew picies

Ive always wanted one of those works bell shifters to see how they are looking forward to the install and review

[russyb]

ive heard that combined with a transgo valve body upgrade its speeds up shifts and transforms the box, but as with everything 350 and auto its a USA only part.... .

[russyb]

Fitted ccv valve today must say a very simple job takes 20 mins at the most

 

Fitted

 

[veilside z]

Well done there, going to be an interesting read.

+1, transgo valve to complement the shifter imho.

[Luke0549]

ohhhh. ive been interested in buying an auto with the works shifter.

 

but as i have read it - it only relocated the ability to shift, not actually speed anything up.

 

so from that point of view - how slow are the gear changes at the moment with the stick?

 

i understand its not going to be anything like as quick as the new s3/golf r/370z/gtr/m3 gearboxes - but is it any good?

[russyb]

right guys had a spare half hour today so fitted throttle body spacer again very easy to fit, havnt had time to test yet to see if it feels any different

 

[russyb]

So as mentioned in my previous post i was attending a local dyno meet so would have been rude not to have stuck her on the dyno to see what she was running and if mods had made any difference pre-map.

So i was last on the dyno but i guess they saved the best till last....

 

any way first off there was an issue with first and second but realised very quickly it was first and second speed limiter so third was my magic gear when things started to happen.

 

final outcome was 257.6 ATW and 235.6ibft of torque which i was very happy with as this roughly equates to 15% drivetrain loss so 296bhp@the crank or at 20% loss 309.4BHP@the crank so im very ready for my 350z Uprev map

 

20% drivetrain loss for tiptronic 350z's

 

it was great day though with tea and a BBQ !!

right guys so a few weeks ago this turned up

 

 

so last week i set about fitting it and i must say it is a very well manufactured kit feels completley OEM, as the tiptronics should have come from the factory imo

 

so all i can say is install is very straight forward comes with a template that needs taping on and just drill 6mm holes through the lower steering column which bolts on the paddles paddle loom needs earthing which i took from my imobiliser loom and the gearshifter end just needs a live which i took from the radio its a plug and play loom from the gearbox so its a simple one out new one in whole install took about 1 hour.

only problem i had was pluging wires into loom before threading them through column first so i had to cut and resolder but it was not a problem.

 

 

and here it is installed

 

i gotta say this out of all the mods i have done so far this is by a country mile the most fun and worthwhile.

 

i would advise anyone with a tiptronic to take the plunge and buy one of these kits....Epic :

So been a few weeks not buying any goodies and was interested in a rear diffuser but nothing over the top.

So decided on a circuit sports rear diffuser which turned up today, I'll take some pics when fitted but here it is in all its glory for now

 

[russyb]

This arrived from the USA today it's not an underdrive pulley as I don't think they are a good idea but it is lightweight and billet weighing 2.6 ounces it looks very good quality so far I'm impressed

[Luke0549]

review of the shifters? How quick is the gear change?

[davey_83]

Oh wow, how much was the pulley? I really fancy one as this made a marked difference on my last tuned nissan

[russyb]

review of the shifters? How quick is the gear change?

 

Paddle Shifter doesn't change shifting speeds at all buddy just makes it a hell of a lot more fun and easier when in tiptronic mode but I'm currently looking to do the transgo valve body upgrade which will speed up shifting

[russyb]

Oh wow, how much was the pulley? I really fancy one as this made a marked difference on my last tuned nissan

 

Pulley was £70 all in which I felt was a bargain to good to pass up i will report back once fitted on how much difference it actually makes

[Luke0549]

is it slow at the moment? (seconds?)

Hi Mate, nice job. I have been looking for this bit of kit for a while. can you tell me how much it was and how/ where you got it? cheers.

[russyb]

ill pm you buddy

[russyb]

update:

 

well ive been putting it off all summer long but i decided it was time to underseal the 350 so i went for POR15 as ive heard very good reviews about it and i must say it is amazing stuff,

but... if you have never done this before i can reveal it truly is the most horrible job you can do on a car,

but im very pleased with how it turned out there are a few bits i need to come back to total time was nearly 3 hours
