Sort of a loaded question. ;) It's a 2JZGTE. Right now it's in stock form, meaning the shortblock is good for sick amounts of power with the right turbocharger and ECU mods. With 10secDSM as a screen name I'll assume you realize the Toyota's factory forged internals, piston squirters, 7 main bearings, etc. that allow the 2JZ's to produce beyond impressive power. The engine is a low mileage take out from Japan and if the selling price is right the car comes with a spare complete engine and transmission.
