yeah Id certainly reccomend unigroup!!
they looked after my r33 for 3 years which made 254rwkw and did a few supersprints in.
my advice for your first outing, is to keep it on low boost.
a couple reasons - it'll be safer on the motor! (but best still to do what andrew and dunc said by getting it on a dyno to see if she's all good!) and you'll be able to handle the car a bit better first of all. i.e. if you get on the gas early on high boost, might bring the rear end around on you for some oversteer, keep it a lower level first, get a feel for the car and the track!
when you taking it to OP GP?
Im racing there this sunday.
what brakes and suspension do you have too?
for brake pads, check out the business trader section - GSLRallysport for QFM A1RM pads
I used them in the skyline and now use them in the mx5 - love them, great price and Greg is easy to deal with
cheers,
Chris!
