hpi turbo manifold, exhaust special hks 2835 pro s dump pipe into a genuine hpi split front pipe into straight through 3 inch exhaust with no mufflers or cat etc......
Runs United E85
24psi
Some small mods to my actuator yielded better spool, response and held boost stronger resulting in a 15hp better peak and 100hp gain at 3700rpm

It's a blistering setup and an almost unbeatable street car being a light weight and highly tuned semi stripped s13 chassis and even my 315/30 nitto Nt01's can't get the power down anymore haha
Responsive!!!!

Loosing boost at high boost levels, suspecting a leak so there is more left in the setup, looking at getting a Plazmaman Intercooler and getting a bunch of stuff rapped up in order to try lower the IAT, climbing towards 50 degrees Celsius at the moment. But the car is very fun to drive, going to E85 is a huge difference, for anyone thinking of converting... Do it its totally worth the money spent on parts. I think the rpm on the dyno might have been a bit off on the day because last tune one the same dyno i was hitting full boost at 4200 rpm. The car feels very responsive

Update

just had a retune 9 Aug 07

no mods from below except 98 RON BP ultimate

more timing added with the boost sneaking to 16PSI then dropping back to 13.5 PSI

235 rwKW

cheers

Mike

I wish that I'd posted the dyno graphs back in 2007, as I can't find them now, but I suspect that the 235 rwKW back in 2007 was likely the dyno reading a little high, given it had standard injectors and fuel pump at the time...

Fast forward to 2017, the engine is now a NEO top and bottom with "unknown" aftermarket cams, R33 sidefeed 555 injectors, Walbro 155 LPH fuel pump, turbotech bleed valve, PowerFC, steel suction pipe, HKS 25/30 turbo.

234 rwKW - tuned by Anthony (Guilt Toy) at EFI Performance Tuning in Newcastle https://www.facebook.com/tunedbyanthony/

cheers,

Mike

Probably cause you put a 1.5mm HG on it lol. Wind the boost up. I'd put a 1.2 back in and wind the boost up for sure with a built bottom end.

I'm running an old spec 3076 on a CRG mani external gate with fresh head and tomei poncams, stock S2 bottom end, only a 3" custom dump and exhaust and made 500.9whp on 20psi E85 through the manual, now 444.9whp through the glide.

is your VCT working? I would check that.. also see if your timing belt is on properly and both cam gears are aligned.

Run more boost too, don't be a pussy

The head gasket was recommended by the mechanic when doing a freshen up on the engine and as a newbie i just went with it, whats the advantage of thr 1.2mm hg over the 1.5mm? Will definitely crank the boost up once i get used to this power abit more but would like a surge set up first.

I will definitely check those when i next get the chance and may potentially take it to a different shop to see what they can get out of it. More boost is definitely on the card soon
