Oh no, sorry to hear about the engine! That is a killer blow.. Awesome of the supplier helping you out! ... Why did it break, was the engine out of a front impact car? Mechanical Gauge during startup should be mandatory from now on. I still can't believe your bad luck. Scrapping a M20 on no oil pres...

I am a bit confused. So you have installed the engine in a non-BMW car then? Mine worked perfectly as i did just tap into the speed signal cable without connecting it to the dash-cluster instruments. I had to buy a signal device to manipulate the signal pulse to get rid of the 250km/h limiter though...

The wire will still be there, just connect it to the speed signal from the engine. Signal comes from the connector on the diff.

You can also buy some gismo of ebay to manipulate the signal, or delay it so you can hit 250km/t+ also.

Cool

What kind of compression ratio and boost did you run?

You got the making of at good chistmas gift there Glenn, not many get E30 M3 V10 for christmas Even if you had to build and pay for it, not bad!

Remember to take some pics outside before you push it in the garage, mush easier to get the Imola II 'flare' trough the lens

For M50 and S50 conversion they often use E28 535 engine mounts. Those are 63.5 mm high.

Nice work man! Nice to see there's a good breathe of E30 turboes up in Iceland to match your volcanos. There will never be to many S50 turboes winkeye Interesting dyno results, you drive on 98 octane pump fuel right? I'm working on my B30 turbo setup (95 octane) and have talked alot to the Andreas@ ...

BTW, to thread creator - I would also recomend you going for the M50. If there is no special passion for the M20 there is no good reason for working extra on welding the waterchambers in the head and always be taunted with the rocker arms issue. A M50 MLS and ARP'ed with flat machined block and head...

Well, Gunni - that depends on getting the map perfectly set up, doesnt it. Orginal parts you can never tell how long will last. Especially if we add E85 bioethanol the EGT drops quite a bit. Two friend of mine run 603whp and 530 whp with M20 2.7L's. The 603whp one had forged rods and stock preface p...

Nice and very useful thread, truely excellent custom work! To bad your selling. You have a better stamina than me when willing to work outside like that. I wouldn't even consider doing a custom engine swap without standing on a flat surface under the roof.. Many of your pictures of different solutio...

Unplug the crank sensor.

The best long term is killswitch on DME + for the ECU and killswitch on fuel pumps.

Remember, the best defence is the custom solutions witch even E30 geeks wouldn't know about.
