Note We do not recommended level 4-5 on standard internals, clutch or gearbox. As a mimium we recommend forged pistons
and steel rods, steel head gaskets, uprated clutch. We also recommend either a PPG gear kit or 6 speed gearbox conversion ( from later STI)

*PLEASE NOTE - We do not do parts fitting here and therefore do not put complete pricing info on each level.
