Just spotted this one

Looks pretty tidy from what you can see in the photos. Why do people use such bad photos?!?!

I owned an e28 M5 back in the late 90's and it was a terrific car. Like any BMW, of that era, rust is the biggest problem, coupled with poor maintenance by some owners. M tax can make some spares expensive, as with e30 M3's etc. Personally, I wouldn't discount the lesser e28's either. A well maintained 528 or 535, with a few choice modifications, can be an epic performer for a relatively modest outlay. The 12 valve m30 engine might be a heavy old lump but it can make an easy 260-280 brake and a shed load of torque. Add that to a relatively light car, by todays standards, and it's great fun.

I opted for a similar route to Ian Elliott and his touring. I believe his car makes a bit more though. The original engine, from the e12 M535 made about 214 I think? Anyway, I had a new head casting that had extensive flow work, larger inlet/exhaust valves from an e34 and a more aggressive cam profile from Schrick. My actual engine came from TWR (Tom Walkinshaw Racing) with 240 but that was whilst running the old K-jet injection. We've since fitted triple 45's and a better six branch and 50mm mandrel bent exhaust system. There are still some other tweaks to be done, such as modifying the distributor, before we get it finally set-up on the dyno. I have also fitted an e34 M5 flywheel and 745 clutch as the torque is what really makes this such a good old engine in my opinion. I know Ian tried an e36 M3 clutch and it only lasted a few minutes.
This is Ian Elliott's engine.

It's relatively straightforward though. Just basic old school tuning really. Don't get me wrong, my skills end at changing plugs and oil but there's plenty of information out there. You just have to watch who you get to carry out the work for you, as some of the earlier posts demonstrate.
ALPINA B10/5 (based on M30B35) as used in the E30 B6 3.5 had the following spec and is pretty much what I have except for the lightweight & oil cooled pistons.
MAHLE lightweight pistons
S38B36 146mm connecting rods (135mm stock)
Hemisphere combustion chambers
Larger intake and exhaust valves
Dr.Schrick 280° duration camshaft (264° stock)
Balanced crank
Oilcooled pistons
ALPINA exhaust manifold
254bhp @ 5900rpm
320 nm @ 4000rpm (235 ft-lbs)
Bottom line is for me, that any m30 powered e28 is great fun and a relative bargain.

Out of interest, who'd you use to build your M30 lump?MAHLE lightweight pistons

Hi Mark,Thanks for that
They rebuilt your engine (and didn't contract the work out)? No mention of any sort of mechanical services on their site?

It was the ECU. Bit of TLC and airing cupboard time has fixed it. Rear anti-roll bar bushes needed to MOT, back on the road tomorrow.
Hopefully it'll rain and I'll go find some roundabouts.
Ahhh - good news Hopefully it'll rain and I'll go find some roundabouts.
You want rain? Plenty here and I'm not too far away from Black Mountain (near Llangadog)...a wonderful place for oppy lock. Just don't mess up. It's a long way down!

Mick (the owner) uses his father, an engineer, for work like that. They do full restorations inc all mechanical & bodywork.Thanks for that
