Don't buy a cheap sh*t eBay intercooler, try get a good second hand GReddy one, or stick with stock.
I'd be looking at suspension too, a good suspension set up makes driving a Mk2 so much better!
I had Tein SS on my old MR2 and loved them, I've got them on my Evo VI now too and they're just as good.
On track they were a bit soft, although I never thought to adjust the settings
I'm probably never going to track the Evo again so these are for sale. Paint is rubbish in them and the tyres don't have a lot of tread left either, maybe do a half day session? ( or more if you're a rubbish driver like me? ) £200 collected from Merthyr Tydfil, not got time to ship them so collectio...
