not necessarily. mana tau MK buy his project from overseas maa..
btw, is Injen a jap brand or US tuner brand? i seem to only see it in NFSU games. if it is indeed western, it could support the fact that that IS a LHD MR2...
V8 no problem fitting. MR2 V8 use to run in LeMans races. (longtitude layout though).
with newer V8s, the engine is more compact & solves much of cooling problems, its no longer a huge pain. MR2 has the correct length just need a little bulk on the width to handle the massive torque the V8 gives.
