21 Turbo Power of the super production car

[Lew21turbo]

Hey guys, just wondering if anybody knew about the amount of power that the super production 21 turbo pushed out? Saw the car had a short side exit exhaust. Must say it's really making me want to do something retro with my 21 like the old days of the touring cars. Just wanted to know if anyone has done this or has any info on the super production cars.
Thanks
Lewis

Fair one on the addon costs. Forgot about those.
Supposing you were already going to a downpipe mod , it wouldnt be "that" bad ..

If you want 300 you will need:

Head work
Uprated valve springs
FBI Exhaust manifold (optional)
Forged pistons
Steel liners
Steel rods

Personally I don't think you do but I'm yet to prove anything close to it.
It seems the std manifold is a restriction so the fbi or the likes is more required than the other items.
And the compression does want to be lower, personally I'm having my pistons machined instead of using forged.

And reliably, not as a one-off shot with special fuel and crossed fingers

Of course, as a daily it's got to get further than the shops and I can't be bothered having to add octane boosters with each refill.
