It really surprise's me that guys STILL believe that the Japanese have to do an engine swap after a set amount of KMS. 1st,it was 30000kms,then 60000kms. CRAP,CRAP,CRAP.
ALL JDM engines come from JUNKYARD WRECKS.
Importers can get you the powertrain,,or the complete front clip from the dash forward if the car has been rearended. JDM doesn't mean more power,infact a Cyclone split intake manifold makes less HP. A JDM engine/powertrain has been subjected to an accident of enough force to write off the donor car.
Rebuild your original engine.
