the S2 im hopefully swaping for my 16valve nova can run 15psi (190bhp) safely but will obviously shorten the life of the engine itself, runs 149bhp at 10psi i think so im thinking it woudl be beter to run that durin the week for work ewtc , then if i wana have a show off blast at the weekend the wack it up a bit??
ps ive never driven one or owned a turbo charged car b4 so be gentle
thanx

 

leave the S2 standard and it will be the cheapest most reliable day to day car youll ever own m8 ( if you look after it properly )

 

apart from killing gearboxes lol

I done 3 in 1 month on my S2 that was running about 160 bhp

 

why do they kill gear boxes? just a weak point on the car or???

 

On most turbo cars go for about 8-10psi. Dont put too much strain on the engine.

Gearboxes will always go if you put more power through em than they can handle cus the gears start breaking.

Hope this helps.

 

wot can u do about the gear box, i guess u can fit stronger "race" ones yea?

 

i run the same box on my xr2 for 20k miles and 2 years, on 170-200 bhp, over 400 1/4s and 0-60 runs and gearbox still good.
