These pretty much keep the thermokinetic heat in the exhuast system to spool up the turbo pretty quickly
twin water spray activate from 7lbs boost onwards.
Sti OEM clutch

Interior:
Defi electonic gauges for boost and oil pressure.
APexi AVr to control boost
Autronic computer running feul managment system

Engine :
full rebuild 2.5lt sti short motor
Argo Conrods
CD forged pistons
Arp Stud Kit
Standard STI head ( balancdd etc ) (AVO400L or 450 to upgrade)
AVO400 turbo...
Tuned to 210kws at 18psi

guy i spoke to over east who built it said, that putting any more boost than that into it wouldnt be wise? as it could cause it too blow?

Now can anyone help me with that? is that not bad for 40 grand? and is that a good rebuilt 2.5 sti motor etc?

???????

Forged pistons and rods are a good start. As for boost issues that normally relates to standard pistons which may crumble at any sign of pinging..

The problem with the 2.5s is they have thin bores and may be prone to ovailing out at high boost appplications. But in saying that the U.S guys are running 25-30psi and have not found this to be a problem (Well there not addmiting it). i think u can run upto 25psi safetly and u have to remember how many times ur gonna be on he limit of the car, not many unless u intend on tracking the car regulary

In terms of pure resale, the sti would be a better bet imo but dosent have all the bang as that 03 wrx in terms of future power. But im sure ud be happy with 230-250kw atw that the sti brings..

The stis engine would also look fairly stock with the standard mount for the turbo so should pass pits fairly easily.

thats a good point, yeah think i might go for that sti with the rebuild, im sure later i could do some more if i felt prone too...

seems like a good deal for whats in it, the guy spent a fair bit of coin, and is a doctor in QLD, so money wasnt a issue...

thanks for the advice

anyone else got some input?

Don't say that. Now I'm gonna want a retune and go from 17 - 20 PSI. ARRRRGGGGHHHHH the stuff you read that costs you money!!!!!

Thats if uve got forged pistons and rods.. Which u wouldnt have unless u rebuilt the 2.5... but the U.S guys have run that amount of boost on an untouched 2.5. I think if u can get the tune right with no pinging then it should last, but very hard to do so.
