Merci merci! 
Couple updates!!
Intake plenum is hitting my hood, so i'm going to cut out some bracing and maybe dent the hood a bit to clear it.. which leads me to my next CF venture;
CF hood - but not likely to debut until next season..
Here are some updated shots! Been making as much headway as possible given the short amount of time i've had to work on the car!
Finally finished our prototype rad cooling plate. Need to make the final cut for the latches for consumer use, but i'll be switching to hood pins as my oil cooler will be in place of the oem latch. Should look awesome..
Anyways, all that's left is oilcooler and turbo ....... Finally..
Oh and its pretty tucked.. Rolling the fenders soon, then off to an alignment at a business near here! Has the full weight scales and all for counterbalancing so i may do the whole shebang
Front's okay and what i'm looking for.. Back is a bit extreme for me..
Then off for tune in 2 weeks

c'est tellement un bo petit projet, sa me donne le gout d'aller me chercher un pti classic rhd mais trop de char dans le garage en ce moment :O .
Belle execution continu le bon travail

Matte white FTW!
Merci!
Installed my oil cooler this afternoon;
No pics with the rad plate installed over this, and the hood closed, but it looks REALLY good.
I dont think that the rad plate and cross member will create enough turbulence or pockets of air to be bothersome. I've toyed with the idea, but for the amount of work to create a flat section to delete this cross member issue, it's hardly worth it.

awsome work !!! Good fabrication !! you gave me some ideas! Look at mine it can give you some to !

So finally, some updates worth posting;
Made my throttle cable up;
Blocked off my AACV
This warranted me to get ditch the balance tube and any other junk to the front.
To get the car to idle without having to feather the gas, you need to adjust the throttle body with the small set screw, then 0 out the TPS (return to .48-.50). Then you're allowing % of air in at idle.. You need to do this warm, since the cold start tables will run 1500 rpm off the bat typically and you'll be compensating for cold start values, not warm idle. Once you adjust the set screw, readjust the TPS to .48-.50 again and you're set!
I'll admit, after messing with the car on, the AACV was nice with power windows, fan and power steering (at a stop, turn the wheel full lock, there is a bit of strain on the system). But with an idle at 1200 rpm, you're good as gold without it.
IACV is also gone.
Got new speakers !
Infinity Reference;
They're now installed.. Pics to come.
Intercooler pipes fabbed up;
Not the most fun from scratch mind you, but it was an experience.
Done.
Rad cooling plate is now mounted. I'll have pics of that soon..
My only issue now is a squealing alternator belt.. Seems to be a lot of load and the damn belt was too long, so my adjuster is out of adjustment lol. Need to get a shorter belt .. But otherwise the CAR RUNS!! And runs very well too..
Stock turbo is in for the moment, but my new turbo comes in tomorrow. I'm running an rb25 wastegate and closing off the EBC for now. Going to spend some time working out small kinks for the time being and get it running 100% before i start messing around there.
Hood pins go on tonight, then alignment this week Driving it to toronto saturday, so wish skyleezy luck on its 5 hour maiden voyage! lol

Thanks Alex!
Belts fixed - was too long. Haig must have mixed up the belts but at any rate, its working great now.. Took it for a quick spin. Needs an alignment, otherwise it rolls fine and drives fine. The shortening of the pipes, coupled with the cams, porting, headwork and gasketmatching has really upped the CFM's, so my once nice and stoich idle is a mere 13.. But at any rate, i kind of expected this.. I'd take cylinder wash and rich condition over lean, so i'm in a good place.
Going to TRY to get an alignment done today.. I installed my hood pins last night (no latch due to oil cooler placement) so the only thing stopping me is my RT 615k's price tag.
Few pics;
Sounds gay but it's too low in the back.. I need to roll the fenders and pop some camber out.. I figure i'm running close to a -3 right now and its really not for me since i'm doing a LOT of distance driving for meets this year (Florida, North carolina, mid US and Toronto).. Sooo, going to need to adjust the height and that a bit this afternoon as well..
My new turbo setup;
This is a pretty deceiving turbo.. My car is based around the 1989 GTSR Gibson racing (Touring car) Skyline, which was an internally stock (cosworth pistons), severe headwork, t3/t4 hybrid turbo and all the dressings. It was a leading car until the new GTR came to fruition...
So being this is a 'replica build' i couldn't skimp on the turbo.. This is a piece of work - built by Herman at Cherry turbo in St. Thomas ontario. He used some pretty outstanding technology to build my 50 trim turbine wheel from scratch, exhaust is the same deal. For my sake, i dont plan to divulge any special info on it such as exducer/inducer sizing but perhaps i'd be down via pm.
The CHRA is a GT30. 360 degree thrust bearings (journal) with a VERY Stringent balance. Journals are superior to BB in a way that the oil intake forces the bearings to separate from the shaft, leaving it float, per se. This allows a faster spool rate, in some cases 200-300 rpm sooner. My idea was to make 350whp daily and have spool below 3500 rpm (16-21psi) .. This is VERY doable with this setup. Not to mention the fact i ported the head quite a bit, and the cams will help move air more effectively. Also my piping is a meter less than stock which makes an enormous difference. I also utilized 2.5" pipes over 3" to cut down on volume. No BOV to cut back on weight but also to allow smoother shifts and a more crisp response (charged pipes are constantly charged, there is no dissipation of air between shifts.. lose like 20% if you shift quick enough vs100% due to a bov)
Anyways! That's about it thus far.. Need to swap oil and coolant but otherwise the engine is ready to hit the dyno.

So.. Small update .. Turbo's in, hoods painted, trunk lids painted..
Took it to Pat at ACSP and laid down a base run of 310whp/280wtq @ 5400rpm and 7psi.. NOT BAD.. Then we lost the tune due to turning the car off and the MAF scales reverting back to stock (HCR32 vs Z32 maps). SOOO.. the car ultimately leaned out and we ran out of time.. Lean condition is due to the thermister voltage.. MAF's run on a hotwire setup - as more air passes over thermister cooling the hotwire, it tells the ECU there is a great volume of air entering the motor, thus enriching the tables. Since the Z32 maf resolution is different than an HCR maf, it runs a higher voltage .. This makes the ECU think there is no air passing thereby not adding enough fuel to the mixture. We should have caught this off the bat but it's really not a big deal!
Also for those of you interested in tuning with Nistune - when you change MAF's from the drop down menu, you need to adjust the AFR's in the fuel map according to the change in the K value. Same for injector latency and the K constant for the injector multiplier.. Otherwise your values will be not be properly represented ie. I'm running 8:1 but my wideband shows 11.5:1.. Kind of butchered map but it's getting me around!
So tomorrow (Monday the 25th) i'm going back for the final tune...
Showed up at the meet on friday, which was a good time for sure! Car had a few paint issues, and my front carbon lip isn't on yet, but she's coming together!
Hoping for 400 on the dyno, and a safe 350whp daily street tune! Fingers crossed..

3900 rpm
18psi
300 whp
300 wtq
Finally done..
1080kg car with such quick spool / so much torque is absolutely insane.. So facking happy!

I'd like to see the print out that says this car is 1080kg.

Gladly.
This was on an alignment corner balance machine - read 1087 and change. I'll stop somewhere tonight (scale or flying j) if the weather holds and snap a shot. If not I've got my full alignment sheet printed out with weight
