Project 12sec R33 GTST Daily Driver

[rev210]

the car is off the road for respray and engine rebuild. Hopefully back this week.

The engine will be stock with a HKS exhaust cam. Running factory turbo and ic. The s-afc II has been sold and a standard safc in its' place.

The rest of the car is still as it was.

So, What's news??

[rev210]

the car is back from the camshaft install, needs 500kms to run in the cam then back for a dyno tune and after that and a couple of little bits sorted the car may just appear at the track for a run or three.

The camshaft appears to have added a fair bit of stick even keeping the revs to 4500rpm and the throttle to 50%. The little factory turbo gets excited very quickly indeed.

any more news rev? Just wondering a few things where and how much was your ogura super light flywheel? I also read your how to guide to get stockish GTST into mid 13's (very good time) and was wondering what was the significance of removing the panel behind the stocky intercooler? Have you heat taped ur exhaust manifold? Do you think a cheapish way to upgrade our crappy ceramic turbo is to get an s15 turbo hi flowed? one day i will hopefully one day get into mid 12's on full street trim. (atm i have 235's 45 ratio 17's, but quite heavy rims that cam with the car)

thanx

Rom.

the flywheel is cheap with the current exchange rate. Go find out at takakaira.co.jp

remove the panel and it allows the air to flow better through the intercooler, better still is to make some ducting for it and cut a hole in the panel instead.

I did not tape the exhaust manifold since it is made of cast iron and when unevenly insulated (tape is a problem here) it cracks due to uneven expansion.

The cheapest way to upgrade the std turbo is to add a 55mm TO4 V-trim compressor into the machined out std housing (you need to machine the ditch again in the same way as the stock compressor housing inlet snout has to prevent surge) , then add a VG30 exhaust housing and machine the snout by 3mm so the standard ceramic wheel has extra clearence and agin it reduces surge. BOOSTD has perfected this idea and made 250rwkw with it , should cost $500 or so to do. S15 turbos are the wrong flange and are smaller than the RB25 turbo to start with.

On the news front my car will shortly be sold. I recently put it on the dyno for a quick tune.

The result was around 240rwhp odd, the power was limited to this upwards of 5,000rpm due to the extreeme intake heat (54 deg C ) and the fact that I did not play with the dial in of the exhaust cam. As usual I did the runs with the bonnet down. AFR's where kept in the low 11's due to the heat.

In it's present state of tune a 12second pass on the 205's should be within reach. Even easier if the tune is taken a little further.

Any Further info?

Boostd is actually makin around 300rwkws now with the vg30 hybrid.

nice

[rev210]

car is sold.

[EnricoPalazzo]

noooooooooo

[BOOSTD]

Don't under estimate the gains from Heat wrap. Apart from reducing under bonnent temps, the wrap which keeps the heat in and causes increases in pipe temp and gas temp. Temp promotes increased verlocity. Remember air is less dense at increasing temps. So there are more than one reason to invest. I had my exhaust, turbo and entire dump wrapped for my 12.9 second pass with the stock turbo.

Dean: The car is being tuned tomorrow. The power can't be compared any more as my internals are far from stock=) The turbo will make 240rwkw to 260rwkw at 16psi on an internally stock engine. Maybe more with more boost and adjustable fuel reg.

[R31Nismoid]

It'd be interesting to see how long the turbo would last like that.

Being a ceramic wheel, keeping all the heat in might harm the life possibly?

[BOOSTD]

Very true.The reason I went for my hybrid turbo is because mine started making some strange noises after some extended 250kmph cruisin with the heat wrap. On inspection the turbo looked fine, but, I rebuild it just in case.

[R31Nismoid]

Yeah, i was just thinking about it keeping heat in... and that's kinda what the turbo's dont like (stock ones at least)

But even if you had 2-3 quick succession runs you could do damage.

I wonder how much extra heat it does keep. Be interesting to find out

[EnricoPalazzo]

good luck tomorrow matt. make sure u post the results mate.

What is your horsepower target?

[murray]

sounds like a sick plan man

[Jolinator]

is it safe to thermal wrap a dump pipe, with stock turbo, mild steal-magnaflow?

cant wait for the results
