Wilson's R33 Gts-t Time Attack Build

[BLK-51N]

Hey guys

Thought It was finally time to create a build thread for my R33 gtst as its coming along nicely and not to far off getting it out on the track for the sau championships. Hopefully for round 2 29th March.

I brought the car back in July 2014 as a unregersted stocker for $4000 with the intention on just entering a few track days here and there but that quickly has changed and now the aim is to build it up for the WTAC to compete in the open class.

Since then I've been buying parts for it most weeks and slowly getting it closer to how I want it.

First was a set of BC ER coilovers 9kg front and 7kg rear.

Also went in were whiteline front and rear sway bars.

Next was a set of R33 GTR wheel which I brought off another sau member.

Which I decided to bring them back to life and painted them black.

Also brought some semi slicks to wrap them in. Brought some nitto nt01.

Over the next few weeks I brought a few more go fast bits. Bpp Billet fuel rail, splitfire coilpacks, apexi power fc with hand controller, tomei fuel pressure regulator, walbro 450ltr fuel pump, Bosch 1000cc injectors, bride low max seats and a pair of D2 330mm 8pot brakes with race pads.

Next the car was sent off to mcqueen motorsport for a full cage. Had a few hiccups there but eventually got the work done after a few months sitting at the shop. Decided on full weld in 6 point cage($2500). Also had to removed the sunroof to give me a little bit more headroom. Now left with a gapping hole in my roof which should be getting fixed in the coming weeks.

Got it home and the gave it a few Coates of matte black paint.

Got to spend some time on the car over my holidays and installed the D2 brakes.

Removed all the sound deadening and gave the interior a fresh coat o gloss white paint to clean the inside up a bit.

Nice work. Keep the pictures and build story flowing.

Next on the to do list is find a panel shop to patch up the hole in the roof and respray the front bar. So if anyone on here knows of a good panel shop please let know.

After that is sorted the car will be sent off to racepace to get a tune with all the parts installed.

Still need to buy either garrett or Hypergear turbo which I have on my daily. Top mount 6boost manifold, plazmaman plenum.

Looks great so far. Whens the aero coming to play?

Tao does the SS2 Alpha with FNT, makes 350kw+. Though on your standard engine...not sure how far the internals go in a track day arrangement.

Most of the guys struggled to hold oil pressure over 350kw.

[Dale FZ1]

Before giving the front bar a tidy up, perhaps figure out what cooler mounting and ducting is needed, and whether you'll even retain the stock bar? Richo's build thread has a lot of good info/pics.

What sort of power will you chase out of this thing? I've wondered how a Hypergear TDO6SL2-20.5G would perform for a track application like this. Mightn't go much past the 300kW mark but it should be responsive and reliable unit.

Aero shouldn't be to far off. Need to get that front bar lower and design up a front splitter. Either looking at getting a rear wing similar to yours or a decent size carbon fibre GT wing. But they are a bit pricey. Still pretty new to all the aero stuff tho.

Yeh that's the exact turbo I've been looking at from Hypergear. I've got the SS2 on my daily and have been pretty happy with it.

Power figure I'm roughly looking at chasing atm is 300-350rwks on e85. But will most likely rebuild the engine this year to chase over the 400rwkw. Considering doing a 25/30 setup to achieve that.

Also decided that since I'm spending all my hard earned money on this car that it was time to insure it with Shannon's. Got a pretty good deal for an agreed value on $20,000 only $500pa. Good to have that peace of mind. Don't no what I'd do if something happened to it uninsured.

New pistons and rods. Edited February 6, 2015 by BLK-51N

Have you done any track time yet, what were the tyres like.

[BLK-51N]

Nah still yet to get it out on the track. Hopefully will have it at winton on the 14th but defs will have it ready for sandown just won't have the 25/30 in it :-(

[timmy_89]

Cool build thread so far, impressive cage! When do you plan to have it finished by?

Will you do any other time attack events? How about hill climbs/supersprints?

[BLK-51N]

Hey well the aim is to have it fully ready with the 25/30 in it by mid year hopefully. But should have the car out on the track at sandown on the 4th of April.

Mainly just gunna enter in the sau championships and the WTAC.

[timmy_89]

Cool, if I see you in the pits at WTAC I'll come and say hi then .. I'm planning to enter NSW Time Attack this year, might look at doing WTAC next year, only in clubsprint class though.

[BLK-51N]

Yeh for sure come in nd I'll show you around the car.

Just hanging out bad to get this ready nd out on the track. See how much power I can push out of this forged rb25/30.
