I have these parts but can't make up my mind which one to go with.
1.s38 m5 motor (3.6,315hp)
2.Euro S50 motor(3.0,286hp)
3.2.5 conversion on s14 (240hp)
4.Us e36 3.0 motor (240hp and super reliable)

Option:
Sell everything and get e46M3 which I have not yet grown fond of
If anyone is interested in any engines above, 3 out 4 of them will be available as soon as I make up my mind.I don't like turbos or superchargers so they are not an option.Biggest waste of money in my opinion.$5-8k for a freakin blower to give fake power to my engine..hell no.I prefer all Motor,no cheating like a ho.

Sell all the engines and build up a Z3 aluminum block 2.8L! *love*

And never sell that E30 M3! *no-no*

I did some quick research and came up with this!

"Previously only the Z3 2.8s used the aluminum block in the U.S. Both engines meet California LEV (Low Emission Vehicle) standards. Fully dressed the engines weigh about 331 lbs." - www.theautochannel.com

Fully dressed...331 lbs.! *mw*

Ok....lets get serious here. The aluminum 2.8L out of a Z3 will be my next conversion...if there is a small miracle that I get a good chunk of change.

Why? Read below!

If you are looking for a car that will be fast in a straight line and on the track this is the motor to go with. Some simple bolt on performance parts you will have enough hp for the E30 chassis to make you grin from ear to ear! :)

dave is right...you can dress up the z3 2.8 nicely...i had almost done that swap...infact i won the auction on a z3 motor, but came across the e36 m3 engine wich i installed instead....

Is the Z3 Aluminum motor strong ?

Anyone hear of any problems , specially because it is all aluminum?

If I remember well , the GM Cadillac aluminum engine was really bad.

So this engine is the same as a M50 but it is aluminum instead, which is alot lighter!

If so This is very interesting for my E30.

well since it is an aluminum block, if you crack it your screwed...but other than that, i havent heard anything bad...it is basicaly a 328 engine but with an aluminum block...the 2.8 isnt going to make your car into a superfast car,its only like 40hp more than a e30 325

I wonder if it could take the punch and heat of N.O.S. ?

Or just go with a M50 Conversion, then put N.O.S. to it.

Well it is a BMW block (not a GM one) and the only block issue that I can think of was the 4.0L V8's in the 540i had a recall (cylinder wall coating problem, not strength issue). That M50 engine will be way more reliable than the M20 too.

If I were to do that conversion I would keep in naturally aspirated (blueprinted, balanced, port & polished, and possibly bore it out...if possible). No turbo, no supercharger, no NOS!!! That engine would probably take a good beating and go forever.
