slaping a turbo ontop of your vr6  is very easy,  just plonk it there and admire it and take a few photos...............

connecting a turbo to your vr6 takes more effort

bdepending on how much power you want massivly affects required effort,  but the head dose really have to come off for pikey spacers :)

Don't they already have a s/c "bolt on" for the VR6?

Anything that 'just bolts on' isn't going to produce that much power as it can't run very much boost, or it'll blow the head off the motor.

That's why you need the pikey spacers Danny has mentioned.... it's either that or low compression pistons.

low comp pistons is how it should be done  but most people never bother on the vr6,   they mostly get away with it because it's not actualy makeing that much power per cylinder.

stock 16v makes 37.5 bhp per cyl. tuned NA 16v can do 50 bhp per cyl on std guts

225 bhp = 37.5 bhp per cyl no more stressed than a std 16v

300 bhp = 50 bhp per cyl.  stock rods, bearings and pistons will hold that happily.

450 bhp = 75 bhp per cyl.  you want to start thinking about shiney bits

600 bhp = 100bhp per cyl.  even with shiney bits any more and it's not going to do reliable imo
