can the eta engine be rebuilt for better performance. If so would i have to get a new crank,connecting rod pistons etc. or can i just get better pistons,cams,valve springs,valves. Not looking for a whole lot of power just better than what i got!

I don't really know how much power you'll get, guys like Randy. M50E30 will know cuz they have done it

All I know is that alot of ppl on the board who have done this eventually drop an m50 in there

I head you get around 180hp .....The reason why is keeping high torque plus hore power.. Well you can also throw in a chip...

An M50 is so much smoother, reliable (I have been hearing alot of M50's lasting well past the 250K mark recently), and it has 70 more horsepower to boot than an M20!

Don't waist your money on that old engine. Save up your pennies for the conversion. Don't get me wrong. There is nothing wrong with the 2.7L eta...it is just not a real "performance" engine.

i think hes just talking a little jump in power....not a shitload...
its a lot cheaper to work with what he has...

There are quite a few guys on the board who did that and eventually went with M50/s50's.....

anymore?

How fast is a lightly modded M50 in an e30?

I never did the E to I head swap. I didn't think it was worth my money to put in an old engine. The M50 I picked up was under 100,000 kms and it came with everything for the conversion.

A lightly modified M50 in an E30 is definatly faster than an E36 325i and it is probably a drivers race with an E36 328i.

I completly rebuilt my 2.7 and got a lot more power then everyone says. I never did any major mods to it, just cleaned it up. Shaved the headmatched the gaskets, file fit rings etc. With the eta, it's a matter of helping make mid range power. Not to give it more rpms, but to use the power it is designed for. My car right now is stock, with a custom exhuast, and i garentee that it will take any stock 2.5 E30. 4 and 0 as of today. I like the torque in the mid range. after having the 2.5, the 1.8 and now the 2.7 i prefer it over all. Except to my moms E46. Thats a nice car.

I still don't think that the i head makes any sense, it lowers compression witch, unless you have a turbo cause power loss. There is a right up on it somewhere on the net, i will find it now so i can post it.

Found it this will be pretty hard to disagree with

I would rebuild the 2.7 if your looking for torque and reliablilty. From what I understand, the 2.7 will outlast most BMW engines, including the M50. Correct me if I'm wrong? I know my 2.7 is no rocket, but its pretty ballsy torque-wise and I've beaten "i" 325's off the line...not in the long run *sad* ....plus, at 125k I still have awesome compression and my engine runs damn good and smooth.

*wave* I think you're missing a key one. I'm just a couple hours away from Orlando, and am selling mine.

*th-up* it sure is. I have raced a few e46 330's, and have beat all of them. I am also running a/c with no weight reduction. No problem :D

I think you guys are right about the 2.7 litre conversion not being a good modification in and of itself as compared to swapping an M50. But, with the proper planning and the replacement of the pistons, crank, cams...well, most of the engine, can result in an awesome powerplant. Couple that with standalone engine management and you have one mean N/A machine. I plan to do this along with boring the cylinders to make raise the displacement to 2.8. It just takes the proper planning and patience to put it all into effect. I'm going to be gathering parts and money for probably a year or more to finally give me the reason to take my engine out.

Anything's possible...

They will last forever, I cahged motors at 314 000 kms, but i changed it with a motor that had 200 000 on it. That was the one i rebiult, runs like brand new.
