Hi,
Sorry to hijack your thread, I have a MY00 Aussie Import WRX and was wondering if you know what the standard power output of these things are? are they the same as UK spec?
BTTT for you

Hello,
The MY97/MY98 were definately the same spec in OZ as UK ie 155kw, 290nm Torque or 208bhp standard. I am not 100% on the MY00 but I would say it was also the same.
Regards,
Mark.

Hello Silver-Sub,
The secret seems to be in the Intercooler. Working with NRG in Sydney, Australia we used a temperature measuring device at the point where the air leaves the turbo and where it enters the engine.
I performed this test with the standard intercooler and then when Nick replaced it with the custom built Front Mount. The difference was staggering. I posted the exact results to the Australian WRX Owners Club Forums a few years ago.
The general trend was on a 28 degree ambient temperature day, the temperature out of the turbo was obviously the same, the standard intercooler would cause the temp at the engine to jump up to around 40 - 45 degrees while boosting, peaking at around 55 degrees celsius if I remember correctly (can't quote me exactly anymore)
The Front Mount, under boost would actually only get up to around 32-33 degrees at the engine while boosting and the amazing part was when you took the foot off the throttle the temperature would drop right down to even below ambient for a few seconds.
Heat soak was still an issue at traffic lights, but not as bad, because the standard Intercooler seemed to attract heat alot more than a 3 inch stainless steel pipe.
The only issue was there was a slight increase in lag of about 400rpm. However, the difference in the top end was remarkable. For us in Sydney it was like driving a Rex during Winter in the middle of Summer ! The sound of the car boosting up was also awesome. You could actually hear the turbo spooling and whistling (because of the Apexi Super Air Intake and the turbo needing to fill the intercooler piping with boost) about a second before you got pinned back. At that time I had a second hand turbo from a Liberty running at 1.2 bar. It was a little out of balance so the whistle was a thing if beauty ! It lasted 40,000kms and when I changed it, it was only because I was bringing the car to the UK and wanted to show up my mate's £32,000 P1. The Liberty was still working. Amazing value for $850 AUD fitted.
Also, I had the fuel pump changed to that of a Ford Falcon which is a 4.2 litre 6 cylinder vehicle. Even when temperatures were 35 degrees celsius ambient, there was no pinging.
BTW If you are interested, the car would beat the standard P1 on a Motorway. Off the mark, 1st and 2nd would be down to the launch. When comparing in gear acceleration, the P1 would win down low, but the mid range and top end in my car would be enough to pull it in and overtake it by about a car length in 4th.
Of course, throw a corner into the equation, then the same driver would have no chance in my car against a P1 ;-) The P1 really is an awesome 'factory spec' vehicle !
My mate, not wanting to be outdone by a car a third his price, got a scoobysport muffler put on. With just that modification, my massive top end advantage was diminished, although I would still be pulling the P1 in up top. I have always wondered what my car would be like with a VF28/VF24 turbo instead of the VF22.

Mark.
