Nothing really!. Last summer I had a slight coolant leak, but that was soon fixed for next to nothing. The only money I've spent on the car is to satisfy my addiction to modifying!
The car came with the usual Jap mods, like the exhaust, air filter and wheels. I've since taken off the original mods and added various performance mods of my own over the past year; such as HKS cams, HKS verniers, Blitz Access ECU, Blitz Boost Controller, Blitz Diffuser, Blitz Turbo Timer, Magnecor HT leads, Khan RSR 17 inch Wheels, Full Body Kit, Cucso Struts, MRD Exhaust (v. loud!) HKS Blow off Valve (soon to swap for a Blitz one!).
I'm not 100% sure of my cars power reading now, I'll have to get a dyno done soon. To give an example of what sort of car the MR2 turbo is, I've **eaten** a Merc SLK 230 Coupe for breakfast, literally blew his Bavarian doors off, and that was when I was running 7psi (v. low) boost and on 95 Octane gas, god only knows what the outcome would have been if I was running 1 bar boost on 97 Octane gas! For another performance comparison, a Jaguar XK8 struggled to simply **pass** me in the fast lane!
