E30kid 24 Report post Posted Saturday at 07:51 AM Better late than never, but here's a foray into the next major step in my E30 I began last week - the drivetrain! This has been on the cards for a few years, but I finally settled on what I want to do with my 300,000km M20B25 and work has begun, have slowly been sourcing parts for it over the last year or so. The juicy bits are basically a 2.8 M52 crank to build a stroker from the original b25, coupled with custom pistons further pushing to a 2.9L displacement, with RHD ITBs, hotter cam and Link Fury to be the brains of the thing. Loads of other bits along the way naturally! Last week I managed to hire a couple of bros to pull the engine, win win because I got free labour and they got to learn cars without the pain and expense of projects themselves. During the week I tore down the engine to get it ready to take it down to the engine shop for boring. Good to see that the weld on the head from the infamous M20 crack two years ago held strong with all looking in order. Remarkable how little wear in the bottom end bearings on a 300km motor! Local engineering shop completed my crank spacer too so the b28 crank should drop straight in now. Todays agenda was removing the rear subframe, as to clean it up/blast/paint and re-bush as I sourced new Powerflex bushes to go in. Tomorrow I'll take stock of exactly what I need to prep and take for sand/vapour blasting and paint prep and tidy the engine bay up and remove the brake master/booster in lieu of the replacements currently in freight. 3 Quote Share this post Link to post Share on other sites
Harper 610 Report post Posted Saturday at 09:33 AM Curious what you think of the RHD itbs when you get them. I'm not far off ordering a set for my M44/42 in my E36 318is. Quote Share this post Link to post Share on other sites

Managed to score them second hand but not actually run earlier in the year, they certainly look the part and seem pretty well made. I've seen the odd set in the wild at this point so doesn't seem to be anything surprising. 1 Quote Share this post Link to post Share on other sites
