whats involved and has anyone carried this conversion out?

is it a case of bolting a turbo on with the matching manifold, drill/tap oil return to the block and lower the compression of the engine with uprated head gasket?

any advice/links would be great

Theres a few of us on here that have done this... oil feed from a T piece where oil pressure switch is, oils return drill and tap return pipe.... manifold to suit turbo and management system... I/C from a volvo fits well too... pm me your e-mail addy for pics..

what sort of bhp figures do you chaps get from this conversion? what sort of budget would i be looking at to go turbo?

and lastly does the compression need to be lowerd? thanks

If youve got the later engine then no lowering of the comp is needed, just the oversized H/G from bmw's would be enough.. BHP depends on your setup/turbo... mine hasnt been on R/R yet but was 200bhp with 240lb ft torque with the smaller turbo i had...

It's difficult to compare the results we've all had from our various setups as we've all gone about it in such a different way.

For example, my setup makes 240lbft of torque, same as blingsta's, but also makes 270bhp which is quite a difference.

strange that is !!! curious what my new figures will be though once mapping is complete

did you get yours mapped blingsta?

blingsta could you send some pictures to Mikool-Wetdriftaz@hotmail.com please? cheers
