310 sounds a bit conservative morgs, specially on a 2.2, still at 1.1 bar ?

GTPSO1 is rated for about 550CFM max depending on what you read. Some sources say 380hp atfw others 400hp...? Assume 380hp is max minus 50-60 hp loss = 330 max.
At 310-330hp atw (max) it will pull from 2500 rpm to near redline like a 15yr old with his first stick book

This is a track motor...it will need to hit hard for long periods and have head room to last. Anyway if I can embarrass most people on this forum around a track with a TD04 the GTPSO1 is plenty

MC Sprint Results TD04 inspired
Autotest Result...

Its almost not worth building a 2.2 litre just to bolt on a TD05 to aim for 310-330hp atw.

An EJ207 + AVCS heads + VF37 twin scroll would do the same thing.

Morgan can donate his 2.2 to me

I have a vanilla model MY99 WRX as a base. So I would need a full long motor to achieve AVCS heads + 207 bottom end = $5k for a SECOND HAND mystery pack from Dodgy...Yuk!!! plus a second hand TS Turbo ? $1K (~$300 less than a brand new GTPSO1) Dial in MY specific application, MY specific driving style, MY existing GB ratios, MY long term plans, MY budget and that's some pretty piss poor advice, for me. I doubt you have sat and crunched the numbers for several years like I have? I will have more than enough power with shite loads of torque. Using it on track is a different world...you will never understand. Let's agree to disagree

Sort of explains some of the suggestions earlier in this thread. They give no consideration of the specific requirements that adamh stated. Sorry got some more Dremelling to attend to

This is going to be interesting to watch

Go boys! Remember to post results!

My complete v7 STi heads cost me 900 bucks + about 500 for full service. I'm sure you wouldn't have too much trouble finding some for the same price.

A new EJ207 is dirt cheap, plus gaskets and all that stuff. Put it all together, and you'll probably end up spending 6k for fresh long motor.

VF37 from a JWS test car....0km old. JDM Factory quality too.

If you are into AHG, sure I'd recommend a smaller turbo such as the VF series for response.
But if you're into Wanneroo or Kwinana then lag means almost nothing.

Response on the street where your more than likely speeding, is it really worth it?

Or some punch on the track with some sack at the end?

All depends on what the car is for.

I'd hardly call any of the cars here Dyno Queen cars!

Response is great, but I'd still prefer a kick in the nuts and fly past someone once their power becomes stagnant at 5k.

You will have more powahs soon anyways Morgan, and I know you want some more lag!

We can always do Wanneroo/AHG/Kwinana and see where the real results are.

How many laps of Wanners have you done to see what you car behaves like? Im going to go out on a limb and say that at the top of the short track, and through turn 1 and 4 (if you count the esses as 2 and 3) your car will be undesirable to drive, there is only so many gears you can downshift before you run out of them, or you comprimise corner speed because you need to be at a higher rpm in a lower gear. Even my car is shit with the VF30 and it sure as hell comes on before yours. We both know that yours rips in a straight line though...

However end of the day an all rounder package is the shit. I used to be obsessed with acceleration monsters (not that ive owned one but ridden in "a few") - but once you ride in something like a GTR that doesnt make any real power till 7k and needs to shift at 8.5, you begin to question the point.

2.2 is the way to go - look at Brads car - 11's all day every day
or
Alex's GETAGRIP - absolute jet on the track with a 2.2 and VF series turbo.

2.5's need sleeving etc, and engineer approval. Much more hassle. A well assembled 2.2 with some more boost and the bigger injectors will equate to 11's.

Tapering a little bit of boost at the top end to ensure it stays within its CFM envelope. 2.1xL EJ20G Stroker, Wisco psitons, Manley Rods, Kelford Cams and head stuff, Motec, Ivan Albins 1-5, Kaaz Rear Lsd, G4 Suspension, 12mm oil pump, 675 cc DW Injectors =

and some new 2spot 290mm rear brakes from Santa.

sounds good. I ran a GTPS01 on a built V7 sti spec C motor..550cc injectors, headers, FMIC, 1.7bar.

Netted me about 315hp at the hubs and about 390nm. Full boost when rolling on in 5th (thats 25psi) arrived by 3200rpm.

I'm sure it will go well. Dont be afraid to run lots of boost though. 1.5 would be a goer..

Thodd · #60 30-12-2007, 03:43 PM

My arguement was td04 with little lag vs td06 with dog lag.

2.2 and midrange turbo is a good mix for most situations lah!
