That's a pretty cool find.

I've seen that graph somewhere.....can't recall though. The other day I was at the Elephant motorsports website and they carry those Euroh-spec pistons from Mahle for about $725/set (6 cylinder). Not sure if they are forged or cast.

VAC motorsports carries some made-to-spec pistons for several BMW motors. Really nice forged ones too. They want $1095 for a set (6 cylinder) and they make 95mm pistons for the M20 :shock:

I hope you mean for a 4 cylinder. 95mm is impossible on a m20. 87mm would leave the pistons seperated by about 1mm of cylinder wall.

Its gotta be a error on their part.....meh, humans :roll:

Have a look-see http://www.vacmotorsports.com/cgi-bi...pl?item_id=485

Yea eta compression is a lot higher than I compression, even stock.

Anyone know the specs on the the M52 2.8 pistons?
Wondering if they could be used to piece together a 2.8 stroker?

[SA E30]

I've also bee thinking about the 2.8lt M50 motor for parts.

On the other hand, is there any way I can print this, cause I've tried to print it landscape, and portait. It always cuts off some of the info... I've even troed pasting it into word, with no success... I really need to print this, cause its a big help to me, especially with the rod lenght and things

Install 323i intake and exhaust system + cam and stiffer springs,
should yeld plenty of power.

Same goes for 325i motronic and 323i cam + springs
