Default Re: Vorshlag $2010 GRM Challenge car - BMW E30 V8

Project Update # 4: That previous update was small, but this one is a biggie. We had the whole team of 7 Project members over last night and knocked out a big chunk of work. I had the car on the lift, the hood off and pizza on the way by the time most of the guys showed up. But just 30 minutes earlier Chris and I fired up the M20B27 for the first time since we picked up the car:

Don't know what changed, but after sitting 3 weeks and with a fresh battery it cranked right up. Hell yea. So... anyone that needs a good running M20B27 engine, transmission, wiring harness and DME its for sale! $500 and its yours.

When the gang all showed up, and had injected enough pizza to kill a horse, we tore into the car with the goal of getting the stock drivetrain out intact. I couldn't remember if the front end came off as completely as the E36, so we wasted a little time trying to unbolt a welded on front radiator support, but eventually we figured out what had to be done - the drivetrain, crossmember, and front suspension needed to drop out from the bottom. No worries, we could raise the car up on the lift.



It was a frenzy of activity with as many as 6 people working underneath, on top (sometimes on a ladder), and inside the car at the same time. The car was grimy and greasy underneath and once we started unhooking hoses it was leaking fluids of every color. There weren't enough drip pans in Texas to catch all of that mess.



All sorts of engine bay clutter was pulled out - radiator, electric fan, condenser, charcoal canister, fuel filter, washer fluid reservoir, a/c lines and compressor, overflow tank, power steering reservoir, air filter assembly, and more. Once the bundle of engine wiring was unplugged and removed, it was time for the driveshaft, body mounted shifter housing extension, transmission wiring, steering shaft coupling, brake lines, clutch hydraulic slave, trans crossmember and and K-member bolts. Then we removed the strut top nuts and raised the car off the engine and K-member...

Once the body was out of the way we hooked up the engine hoist and got the engine and trans into another bay, out of the way. While we were at it we weighed it on the corner weight scales. The M20B27 + 5-spd was 497 pounds.



Chris pulled the rotting transmission tunnel insulation mat off, as this tunnel might going to need some "persuasion" to fit the transmission and bellhousing we have in mind. We took some measurements and the framerail to framerail distance on the E30, at the bottom where its tightest, was 27". The VH45 engine is 28" wide, so it won't be going in from the bottom for mockup...

It was a good 2 hours of work, and everything came out cleanly and quickly, not bad for a bunch of E30 noobs. This weekend I'll get the engine bay, old motor, and K-member pressure washed and cleaned up. Then we'll drop the VH45 motor in from the top and see if it fits... if that doesn't work we've got back-up motor plans that look to be more exciting than even this DOHC V8. Stay tuned...
