I now own a second E30

[nando]

Clean interior, being from the states RHD fascinates me.

I could be wrong but isn't ABS in e30s not worth jack?

do you have 3 left feet? if not, then ABS, even in an E30 with only 3 channels, is better than what you can do by "feel".

wow dude. that is really nice. cant wait to see how it turns out

mtree crank?

Haha, was not trying to say that by feel I am better. I just like the feeling.

Yeh pretty excited. Just trying to weight up whether to go with M44 rods and S50 pistons for M42 rods and custom light weight pistons, I think the latter will end up with less rotational mass.

Also for reference the M42 crank weighs 14.5kg and the M47 is 15.7kg. With some Knife edging and lighting I should be able to loose 2-3kg of weight.

mtree crank?

BMW M47 Crank, picked it up from a guy in Melbourn.

Best part is it only cost me $700 was an absolute steal.

$700 for a crank doesnt seem like a steal to me, but I didnt even know what the M47 was How much additional stroke do you get? Not much info in my 30second search

you are usually looking at about $1000 to buy one in euro plus shipping so it is cheap for me.

going from 81mm to 88mm, meaning I go from 1.8lt to 2.1lt and about 200whp once I am done.

[2mAn]

Maybe my math is off, but I got ~1950cc with the 88mm crank. Either way, that will be a nice bump in displacement. I know you mentioned custom pistons, so I will assume thats where the additional .1L is coming from. Should be a blast, I love seeing engine builds that break the norm.

What else do you have in mind to get you to double the stock M42 power output? headwork + cams?

[Massimo]

yeh I will be boring out to 87mm for the pistons.

looking at using M44 valves they have a smaller steam. Probably go some new valve sprints and upgrade the cams. Not sure on the profile yet.

As far as porting goes, not planning to go crazy, just want to match the ports smooth out the transitions and contemplating on shaving down the valve guides to match the port walls.

as for the intake I am going to go with RHD engineering ITB

Here is a thread about there development

and finally RHD also do a 3kg fly wheel which I will use as well. Combined with MSV3 I should have not worries reaching 200whp

wow, that is going to be a fun car! 87mm bore and 88mm stroke, I love it! a built (almost) square motor. should be a riot. I will be watching for updates.
