2.7l @ 16psi

I'm sure Alain will be happy with the car (if he ever decides to stop modifying it and decides on driving it some). I'm just glad that this car is finally running! Initially, many people worked on it (or should I say butchered it?).
The car started as a 2.5L, it has the Vitesse Stage 3 kit for the 2.5L. It also has the Vitesse Cam and Wasted Spark.
Based on the dyno chart, the car should be very "fast", the powerband is very healthy.

Earlier spool. LOTS of torque, and it will breath a bit less up top. I believe ST broke a bit over 500...or maybe it was 49?, with a 2.5, STG II and a stock bottom end. It seems like it was 493 @ 23 on rocket fuel. I think he was easily at 350 ish with standard 93 octane at about 15 ish? PSI. Search Special Tool and you'll get a decent approximation. I believe his 493 was with a standard head.
What I'm saying is that you'll need new wheels and tires if you run the STG II with a 2.7. It's gonna spin em!
in 4 gears!

It'll be interesting to see. I have my doubts as the turbo was never designed to perform such a task.

Chris White can tell you as he is using it. The Stage II will spool sooner (more torque earlier), but will run out of steam before the Stage III. The Stage II is rated for 380-400rwhp.
On this engine you have many components working together to yield such a healthy performance. 2.7L engine, head, cam, engine management, Turbo....

Ehall, I never owned a Stage 2. The numbers you qouted are from a stage 3.
Regarding Alains' car, The stage 3 turbo will not make 500+ HP at 16psi.
I made 533rwhp at 2 bar boost with massive headwork, 4 into 1 headers.

It's good to dream! Do you have a boost graph from the dyno run handy?

I stand corrected.

My street car has an MID 2.7 wTec3r, tial 38mm and some other mods along with John’s stage II.
It makes for a great street set up, the turbo spools very quickly and smoothly. In fact it doesn’t “feel” fast because there is no delay before the power comes on.
I still remember the first time I accelerated up the on ramp to the highway – I was thinking that it was not as fast as before…until I noticed that I was at the end of the entrance ramp at 110! I had to brake hard to merge with traffic. Once nice spec I like with this set up is sub 10 second 0-100 times – and that was not using a ‘drag race’ start!
Sure, the stage III would have produced more HP at the very top end but at the expense of the midrange performance and drivability. If you look at the dyno charts at the beginning of this thread you can see that the HP is rolling off before peak RPM, there is a little power there if there was a bigger turbo, but then you would give up the nice torque curve a bit.
Also – the smaller stage II will be more efficient at the lower boost settings – the key to the performance of this motor.

Thanks for the info guys,
I`m starting to think in the direction of a new or fresh engine using some of the stuff I allredy have on my current engine..
But would be nice to see around 400whp though

If you decide to go the 2.7L route, your 2.5L software must be reprogrammed for the 2.7L as the ignition varies. Then, it might be a good idea to upgrade for the new software to be announced shortly!

I like that 0-100MPH time

Oh yes.. I`ll shoot a e-mail when and what I decide . New software sound interesting
