awesome, they'll be on my shopping list. i figured it'll probably more cost effective to just get a silvia or a skyline, or something if i want speed. but i got an other question, does the rim size makes any difference in handling? or it's just a matter of looks? I think im running 14", so it looks a bit tiny in my car. I bought it for real cheap 2nd hand, i think the dealer had throw in smaller wheels. cheers! Exactly. A supercharger kit for 1ZZ-FE around 3k isnt much but is not exactly a large gain in power, would still get chopped by most non-eco cars on the road. Turboed 1ZZ is moderately quick but for ~10k, might as well sell up lol In terms of wheels, a little bit bigger like 15" or 16" is fine, but too big is heavy and will adversely affect handling. I recommend a slightly wider tyre patch on a wider wheel but not marshmellowed (too wide on thin wheel) causes sidewall flex when cornering. Something like a 16x7 with a 205/50 is plenty for the amount of power you're putting out and a good amount of sidewall for comfyness on the street
