M10 mild performance rebuild

[rommaster2]

"Mild performmance rebuild"

Raise compression, increase displacement, add lift and duration to cam. Make sure you're using a head with the 46/38mm valves.
Put it together with thought. Replace every worn or suspicious part.
Pretty much the route I'm going with M10. Don't know any other route and don't know how to do it without spending a few coins. Check out my project topic about my parts pile, you'll get a general idea of what I'm doing.

This is my general thought process on it all though i'm gifted with the challenge of living in california so i get to worry about passing both a visual and a sniffer for emissions testing. Really the main thing that this limits me on though is the cam and compression, though it helps i'm not looking to build some crazy powerhouse, i just want it to have 130 to 140hp. A this point I have an idea of what parts i need, its just a matter of getting good deals on them :).

No ITB. Weber DCOE 45 carberators. The car was built up by Korman Motorworks in the late 90's when it was imported into the US. No built thread but the M10 was a 1.8L bored and stroked to 2.1L. This thing rips!

Maybe you should do one of those M50 swaps all the cool kids are doing and sell me this M10.

also big and long intakes (36+chokes), balanced exhaust (4:2:1, 2"+), high diff ratios (3.9:1 or higher), lightened flywheel, hi-po ignition :)

Engine was built by Korman Motorworks.

What ITB setup is this? Is there a build thread?

Rom, if you're in CA, the carbs won't fly there.

That's where the M42 really will win- swap all the parts, document it,
and if you have to get ref'd, you WILL be able to pass-
you've 'upgraded' to a cleaner, more modern engine.

Not to say it will be easy, but it WILL be legal when you're done.

Then you can chip it afterwards...

Thats my only other consideration, i understand the carbs wont fly for smog so essentially I would be stuck running the stock injection system. Really the appeal to building the m10 is that its different, and its a swap I can do in a weekend if i build the motor on the side then drop it in.

Really it comes down to also if i can get an 02 motor for cheap to get the rotating assembly, if that comes together for me then I know i'm building an m10 for sure. Got a couple months before i can do that though as i finally moved into a house and have my 86 xr4ti i gotta fix so it will smog.

...as in, the bosses aren't there for the E21/E30 engine mounts. But the 2002 parts to go 2l will fit into the E30 block,
you use E30 ancillaries, and get a genuine 2 liters for a few (up to 20) fewer pounds than
a 2002 block...

If you use a 2002 block, make sure to do some homework about engine mounts.

Most of my build is from IE Motorsports. They have quality parts. Check my thread on all of it

I'll have to keep them in mind, just looked on the sight and they do have the pistons you need to use with the 318i head so thats already good to know.

Really i've got a couple things that are up in the air financially right now that once they get settled in if i can find a steal on a 2002 m10 I may just be in business. I'd really like to get a motor built in the garage to just drop in so i'm in no huge rush because my e30 runs and is my DD right now so as parts come my way i'll get it figured out.

I will say though ireland engineerings website has so many goodies :).

Look on Ireland Engineering under 2002 parts. They have a bunch of great upgrade parts.
