CERAMIC COATING BACK :-)

Finally got the heads back and on!

Just waiting on DLC tappet shims to arrive now to continue the build. Should be here next week we hope :-)

New ARP rod bolts fitted and stretched today.

Pitson combustion volume also measured :-)

Should get the heads back tomorrow!

Crank Girdle fettled and Big end clearances checked. However...... Not happy with the feel and stretch of the rod bolts (They may have been on the over torqued side when first built) so have ordered a new set of bolts from ARP. We just cant take chances on a 1000bhp build!

this is where we got to the DOH! bit. Cant turn the crank over fully :-(

Crank and pistons installed today. Not the easiest when you get to this size of bore! pistons tip quite easily....

Anyway. Went relatively smooth except for the rod bolts hitting the new crank girdle :-( only about 1mm of interference and only three of the rods touch but still. The brace will have to come off for measuring the big end clearances and rod bolt stretch anyway so not a huge prob.

Please see new pics below :-)

Super secret specification Cosworth Turbo Camshafts. 1 offs and not available to the Public.

I salute you Cosworth! Am not allowed to give any specs so please forgive me ;-)

Measuring Main bearing clearances. All great with a variance of 0.0025" accross the 4. The one with the tightest clearance had the most wear on the old bearings ;-)

Few parts arrived today so on with the build :-)

Block being painted and prepped

A few photos of our progress.

Just waiting on some trick parts from the US to carry on building her :-)

You can see the bearing wear on mains & big ends in some of these photos. Nasty marks but remarkably appeared to live with it!

This photo shows the damage on the Thrust washers.

We are going to modify the electronics so in the future we will be able to start the engine without having to have our foot on the clutch loading up the Crank Thrust washers.

Engine out!!!!

More photos

A few photos for starters.

He has indeed gone for the Racepak digital logging GPS dash along with a full range of AEM gauges which will all be logged by the Racepak.

The car is sporting one of our custom 85mm Radiators for cooling along with special coolant mix, extra bleeding points and mahoosive SPAL fans. Mr 420Z is not a numbers man! He drives the car like he stole it so it will certainly see some anger. We would never recommend this set-up for a track day car however he will definatly be going to Santa Pod to see what times it pulls. Should easily be in the 10s but only time will tell!

We cant wait either!

With our good friend Mr 420Z we are now preparing to get 1000bhp from the VQ engine!

This thread will be following us as we go from 656bhp @ the hubs

( http://www.facebook.com/home.php#!/vide ... 8&comments ) to a target of 900bhp @ the hubs

656bhp was achieved at 17psi on Shell Vpower without NOs. After the refresher rebuild we plan to run 27psi with race fuel and then "top up" the rest with Nos as Mr 420Z has requested :-)

So far we have baselined the car on the Dynapacks and have now stripped the whole powertrain out to get her ready for 1kbhp!

On the cards is

Ceramic coated manifolds & Turbo

Turbo blankets

Cosworth 290deg Camshafts with upgraded DLC tappet shims

All new Bearings (mains & Big ends, thrusts)

Cylinder head rebuilds seats, valves etc

Block preparations

Wizards of Nos full wet system

Remap of the AEM/GEMS Hybrid engine management system

So far we have found:

Brian Crower Crankshaft = Perfect

Brian Crower Connecting Rods = Perfect

CP 100mm pistons = Perfect

Main bearings = 55% wear

Big ends = 65% wear

Thrusts = Severly damaged

Tomei Camshafts and Nissan Tappets = 90% perfect rear cam lobes damaged on nose slightly

Turbos = Perfect

We are putting the bearing wear down to an occasion when the car suffered low oil/starvation and the cam wear to the Non DLC tappets and oil starvation.

Even so it shows that with sufficient cooling the VQ block will handle power in excess of 750bhp without issue.

Photos to follow :-)

Has to be one of the best 350s ever that car!

Made 760bhp at the crank on our old dyno! Looking forward to seeing what the dynapacks will show when he brings her up soon!

MS DOS stylee is just fine, if its good enough for the old Motecs its good enough for the UTEC! You'll also be pleased to hear that all of my laptops have serial connections!

So you like Vipers? We've done quite a few in the last 12 months mostly supercharged but all on standalone ECUs! I didn't used to like them but after working, driving and weighing them (Near enough 50/50 distribution) i really like them! I recommend them highly!

Sub Zero,

Have we worked on 350Zs? Yes (760bhp 420Z twin turbo, 435bhp Supercharged, 305bhp Normally aspirated are just some of the cars we have mapped)

Have we used UTEC before? No, but we are confident we will be able to do it. As long as we have the communications cable and software we will be able to tune it. We are not ECU specific here and map all types of Electronic controllers. We've never been introduced to a system that we can't master. Luckily all engines obey the same laws of physics so the tuning is irrespective of ECU Brand :-)

It sounds like you may just be running TOO rich. If its showing lower than 11 then its a possibility. I've also replaced at least 10 Ignition coil packs in the last 12 months on different 350s so it may also be worth replacing them with new ones if you can afford it.

Let me know if you would like to pop over sometime.

What are the hiccups your having Sub zero?

We're in Silverstone and could help you out :-)

A road car like a 350z will not be able to make use of 600 bhp, let alone 700 bhp, it wont be able to put that power down IMO. Youl just be spinning the wheels in every gear. But goodluck to what seems like an awesome project!

Thats why we developed the Advanced Racelogic Traction Control!

We are an official STOPTECH dealer and we offer the following retail prices

NISSAN 350Z FR 4 POT 332MM £1200 +vat

NISSAN 350Z FR 4 POT 355MM £1500 +vat

NISSAN 350Z FR 6 POT 355MM £1750 +vat

As forum members you recieve 10% off these prices.

cheers

our 420z hit 720@ the crank at 1bar......

quite quick

IIRC the most powerful UK Zed is around the 550-560 mark.

 

Who's doing the build and tuning for you?
