Eta engine with I motronic?

[modifiede30]

I've actually heard that the 524td cranks break more often due to the prior stresses of having the turbo torque, whereas the stock eta didn't really have all that much stress on it. Ideally, an automatic eta crank should be in solid state and last quite some time.

its just what i remember hearing from jordan

You are kind of right.. From what I have collected, the eta crank can probably be run to 6000 rpms all day long and you should be able to sleep at night. You wont need to go much beyond that, but I have a feeling 6500 once in awhile wouldnt be a problem. Another thing to think about is that the eta only has 5 main bearings instead of 7 like the 325i to keep friction down. (i believe this is correct, i am quoting from the site that built the eta turbo, although i dont think they retained a single eta part).

I want someone to build an ho eta torque monster. (or i may do it someday) I believe it would be similar to some of the new diesels bmw is building. can you only imagine an eta with 220 crank torque without really breaking the bank too much? I think it would be a real nice autocrosser.

all the m20 use 7 Main engine bearings. The eta head uses 4 bearings versus 7 for the I.
The newer 88 up I block is supposedly the strogest m20 block due to a change with the bearings.

i suppose they were talking about the head then.. wasnt paying much attention. i know this is not relavant, but i had a fiero with the 2.5 iron duke which reminds me a lot of the eta because of its low redline, low hp, moderate torque. They sucked but apparantly with a few bolt ons, the bottom end stock would literally spin to 5000 rpms without worry. the redline was about 4800.
