I get that with mine as it is, everyone thinks its either boosted or a 2.0L But on this matter personally rather than the 2zzge (celica/corolla sport) i would go for a honda k20. The engine is much better, responds to n/a or boosted mods much better, cheaper for parts, more reliable. And the same amount of work to fit. Custom mounts (prob adjust hasport mounts to suit) driveshafts, wiring etc etc I know that goes against most peoples thoughts but you really cant go wrong with a K20
