1987 - 1991 M3 (E30)適用.285 hp/4000 rpm.
One of our most popular items, TMS E30 M3 2.5L Engine Conversion kit uses factory BMW Evolution III parts to convert the stock US 2.3 liter engine into the European Evolution III 2.5 liter engine. Increasing the displacement and raising the compression yields much more torque-50 ft/lbs. gain @ 4000 rpm.. With a stock head our 2.5 kit will make over 225 hp, add cams, exhaust and a Stage 3 head (below) and over 285 hp can be achieved. Our kit includes everything you need to convert your 2.3L into a 2.5L. We highly recommend upgrading the intake and exhaust system to allow larger 2.5L engine to breath. Call for more details. 2.5 Kit: Genuine BMW 2.5L crankshaft w/ bearings, nut and spacer for crank, 2.5L head gasket, M3 bottom end gasket set, TMS 2.5 custom chip, Wiseco/TMS 2.5 forged piston set w/ rings (11.25:1 compression) , rod bolts and head bolts .
