Hi all,

My 3 door is currently on standard gearbox and diff with standard 205 bottom end (rebuilt circa 8k ago). It had a t35.55 with siemens 55 injectors, l8 and a live map off Tony@turbosystems. Also has everything else for this state of tune, exhaust, cooler etc. the head and cams are standard at the moment.

Im looking to go to the next level after 'finding' a few spare quid. Just after some advise really. Car is currently around 380ish bhp with 30psi boost. Will not be looking to change box/diff/bottom end so please dont suggest that.

I know i'll need an ab07 (not interested in pocketing pistons) but how benificial would the outlay of head work be on a T36 or T38 or gt3071? What turbos would people suggest out of those?

What types of power out put would i be looking at?

Any advise welcome guys.
Thanks.
