I have fitted one of these scrapers for my m20 2.8 while the engine was on the stand. Bloody time consuming because you have to have 1mm clearance between the crank and the scraper in any location, so its a matter of trial fitting, getting a 1mm feeler gauge, rotating the crank and marking where the...

Hey mate, good to see you on here. Do you recommend setting the tappets when its cold or hot? I had better results with my "tick" when I set them hot. I am going to try 6 thou at the cam. The one thing is, I did have the tick straight away after I built the engine, with had a full head reco but I le...

M52B28 Crank

M20B23 or M20B27 Rods

9.7 M20B25 Pistons (Flycut for larger cam)

+ deck block 0.5mm and add VAC motorsports Adjustable cam pulley.

Cam: 288 Schrick

JB Racing Flywheel

IE HD rockers

All this would make a very nice M20 with mid 10's compression as Reggid says.

My next stroker build I want to do I am going to use a 731 head, so I can run flat-top pistons and get the compression right up. Just trying to find a 731 head here in Aus is a bit a of a challenge unless I buy a whole motor which i don't have room for...

Hey mate, I have not seen a 320is downunder, probably my favourite e30, I might even like it more than an E30 M3 (which i have just bought). Where abouts are you in Aus? I don't know about the E90 rack conversion, being bigger probably won't hurt as a e36 rack is smaller than the e30 rack and requir...

Yes I had his chip fitted to my car when it was semi-stock, nice chip. I then ran with it while I was running in my 2.8 stroker with a Dbilas 276 cam and alloy flywheel, and the car was totally fine with the stock AFM and computer and that chip. I am now running the WAR chip and MAF conversion, and ...

I am running a 276 dbilas cam in my M20B28, and metric mechanic beehive valve springs, which I tested and have the same tension as the stock dual valve springs, just in one light spring. I chose this cam for its good dynamic compression qualities, and high valve lift (11.5mm). IMO it suits a short r...

For the ITBs I'm going to try hacking up an intake manifold so I can keep the stock injector locations and welding an adapter plate to it so I can bolt up some bike throttle bodies. I've been looking at the Triumph 675 throttle bodies because they come in sets of 3 and are separable. They are 44mm ...

I am hoping they are just taking some time to settle in. the Dbilas cam specs say 2mm clearance minimum, as that is what I achieved with the 2.5mm MLS head gasket. Everything is new in the head, new Febi rockers, new eccentrics, head fully reconditioned. I just didn't replace the bolts and nuts for ...

So the 288 was causing the valves to hit, and increasing valve clearance? Got any more info on this? I have 2mm clearance for my pistons to valves, I hope that is enough. I might borrow a bore-o-scope and have a squiz inside. The reason being is my tappets are requiring constant adjustment, they hav...

Here will give you an idea of how much to cut the pistons for the valve reliefs: http://forums.eurocca.net/showthread.php/39849-M20-Cam-Profiles-revisited I would say around a 1mm recess extra on both intake and exhaust to be sure. But you will find that out when you trial fit everything. Measure yo...

Nice combo for a high comp build! Go the 9.7 Mahles, copy the ks skirt shape, and away you go. How much clearance are you going to go with the piston skirts to crank? 1-2mm? Are you going to deck the block? Or leave the deck as is, and you will have room for the 288 cam. If you were to deck the bloc...

I don't think it is worth doing, IMO the throttles are too big for the 2V M20. If you ran the throttles far enough away from the head you could taper down nicely to match the intake port, but you are limited with room to do this.

40mm throttle butterflies are ideal.

Who has done a bike carb setup?

say with a tolerance, the specs give you a max measurement of 10.5 mm, and a minimum of 10.3mm. then blueprinting that part would be coming up with a measurement of exactly 10.4mm, half way between the minimum and the maximum tolerance. that is my take on blueprinting anyway. very time consuming and...

Be careful skimming the head too much. You need minimum .030 clearance between head and pistons, and .060 thou clearance between valves and pistons. I fitted a head which was around 124.4mm thick, I think stock thickness is 125.5. So My head had 1.1mm skimmed off it after several rebuilds. to get th...

Thanks for the replies guys, we are onto it.

I now want to know when this car went from the USA to Japan, and why. It was delivered new to BMW North America.

Hi there,

How would I find out if a 87 E30 M3 has the original motor fitted to it?

I am looking at a jap import to australia with very low kms and just want to make sure its all good.

Here are some pics I have posted in my local forum:

I have beem looking at buying an M3 for a while now, I think I want to bring an original unrestored Euro spec one in from the UK or Japan.

I have some pics I will upload soon. no hole in lhs where it should have. there is no carpet in car....

Hi, I am looking at an e30 M3 to buy, it is in pretty poor shape, but it has all the good bits, like dogleg box, LSD, s14, 17 bbs wheels and it has been converted to rhd which is good for me down here in Aus. I have put the vin number into realoem and it comes up as a 1986 diamond Swartz m3, which m...

OK fair enough, would like to hear an m20 at 8000 rpms!

I would be curious to know if they used the stock timing belt, I am not sure it would be suitable for high revving, high precision valve trains.

The problem with going past 8000 rpm's is the 2v head with the funky rocker design that has conniptions above 7000-7500rpms. I would be happy with peak power in the low 7's, like 7300rpm or something. That's enough of a revver for me.... I have been recently told that the early cast cranks like the ...

I'd like to build a 2L M20 big bore short stroke long rod i recon you could make 250+hp screamer without much problems and would be revving sky high but i dont have the cash so it'd be a 3.1L if i did it again so even when off cam there is a little bit of pull to it Why 2l? Some old school people I...

Or you can go Dblias, they have a wide range of cams, I went with the 276.

I drive mine daily, 40+kms each way sometimes. Get close to 30mpg (10 litres/100km) and I have a 3.9 diff. Love it. If I use a/c then it goes south quick.
M20b25 with BBTB/exhaust/chip and 4 pintle m50 injectors.

Hi mate, Unfortunate to hear your engine is not falling together..... I made it sound prob easier than it is, it has been a long road for me also. I have had more pains with the scraper and head though, but the crank was good to me. Time will tell with mine, it goes in soon. Screech, my workshop is ...

I have fitted the m52b28 single vanos crank to my m20 block with no clearance issues, and if you have a look at my thread its got a blue tinge/tint to the crank. http://forums.eurocca.net/showthread.php/40730-M20-2.8-stroker-build-using-all-%28almost%29-factory-parts I would stick with the m20b25 pi...

To me it sounds like a vacuum leak, very common on these motors. If you can get access to a smoke machine that is the best test. Check the attachments to the throttle body, esp the ones to the booster. Also there is a way to rebuild/repair your idle valve: http://socale30.com/theforum/viewtopic.php?...

yeah what he said....

In my 2.8 build I have decked the block .5 (or just under .5) mm to get the pistons back up to the factory height using the 130mm rods and b25 pistons. My head has been machined a few times, so I have run the thicker gasket (2.05mm). So my 2.8 is going to have some nice compression.

Great, I am in. I am keen to use the factory airbox, so I will need to source an adapter.

A mate here in Sydney who is a member on here has one of Ant's chips, and loves it. (for a standard AFM though)

Reggid should chime in here, he is pretty knowledgable on camshafts. Your bottom end power will depend on your compression ratio.... Stock compression ratio is 8.8 so a 288 cam will be a dog on a stock motor. I went with a DBilas 276 cam for better low end power, even though my comp will be up aroun...

Been looking into this aswell. I ordered a miller setup up but didn't arrive, got a refund but none too happy. Ant from A-tech doesn't do them anymore (i am in the industry aswell so I know how difficult customers can be) so I am back to the old barn door setup for now. Got a few chips coming from a...

So it looks like $828 (not VAT) Aussie plus shipping IF 10 blokes get their shit together. I guess shipping would be around $200? So a touch over a grand for the six branch plus the cross pipe.
