http://youtu.be/Ny3sIHZT074 BMW E30 M3 with an LS1/6 Corvette engine & Camaro 6-speed tranny. The LS1/2/6/7 GM engines are an engineering marvel of low weight, high power, emission friendly, easily hotrodable aluminum, plastic and computer. 7. Installing an LS1/2/6/7 engine into an E30 is no more expensive and no more work than installing an M50 or M52 engine. 8. The total weight gain over an E30 with an S52 engine is about 50# but with over twice the hp and torque of the S52. This little 450 hp beast has brought my wildest fantasies to reality. It idles like a well tuned 36 hp VW engine. It has instant throttle response and tremendous, smooth, power with no low end lag. It has a good, civil but obviously not stock, sound, and it looks like an original, pristine, bone-stock ’88 M3 inside and out except for lowering, aftermarket wheels/tires, larger exhaust tips and, of course, the engine compartment. Since then i have added a aux 20 gal fuel cell, bbs wheel, 3.5 inch straight exhaust , dyno tuned it, new radiator, front bumper kit, rear wing, 450 horse power. If you paid yourself a buck an hour to build this car you’d be in it $50,000. If you paid someone else to build it you’d probably spend $75,000 or more. The first step was to obtain, in this case rent, one of those foam replicas of a small-block Chevy engine and a tranny and make a trip to the local junkyard that contained a few E30 chassis’. Imagine the looks you’d get walking through a junkyard on a Saturday afternoon with an engine under one arm and a transmission under the other. Anyway, it became obvious that there was plenty of room in an E30 engine bay for a small-block Chevy so I knew the LS1/6 would also fit. A T-56, 6-speed, aluminum Camaro/Firebird tranny bolts-up to the LS1/6, measurements indicated it would fit well, was light weight and the gear ratios were perfect, i.e. 60 mph at 1700 rpm in 6th. The 212 mph at 6000 rpm won’t be of much use for me.
