Thank you for sharing guys! I built a 3.0L M20 for my 89' E30 Touring. Its a lovely engine, but its so costly to build, I dont see many people building their own. That being said.... So happy I did. Thank you for sharing more info with the world on this lovely and unique engine choice!

Hi Graham I read your forum about the e30 race car and it led me here 😊 I too play with m20s, if your going to use that m54b30 crank don't spin it over 7250rpm as they seem to brake, harmonic issue, we just finished a m20b31 and made 206rwkw and 340nm of torque, very healthy, I'm just finishing a 2.9 ATM that should make 330-340hp at the crank, the 84 or 86 mm cranks are the best to use for a race car that will do sustained revs
@PenguinMotors
@PenguinMotors Год назад
I only spin the current engine to 7200 as its on standard rods. Which fortunately is where it peaks, making the engine bigger will lower where the peak occurs anyway. Without a close ratio gearbox it wouldn’t make sense to make it more revs anyway

We put an m52 head on bandsaw in the early 2000s trying to see if we could get 9/16" headstuds to fit . Ended up just using 1/2" and o ringed the block. Alot of trying n failing but we succeeded in having the 1st 1000whp m52.

Mate, if you use the 2.5l 885 Head on this Build with this flat top pistons your engine will be proned to knock, because you will eliminate squish area.....
@PenguinMotors
@PenguinMotors 2 года назад
thanks for your input, in most instances i try to run a tight 0.030 squish, but its not possible with all engines, there are quite a few which don't have any. In this case the set up you describe is the same as my 2860cc engine which is on a standalone ecu and properly mapped, it makes 285bhp and has proved totally reliable, bearing in mind its in a race car so is only driven flat out.
@bmwmaster81
@bmwmaster81 2 года назад
@@PenguinMotors Maybe it's a try to go with 2.0l Head. Squish would be there and a quiet high cr.....good porting would be needed ... difficult but doable.

Hello, nice build i have my self a 2.8 stroker ! I have an issue that my timing belt at the camshaft pulley has the tedency to go near the head instead of the midle. Actually 1 2 mm ar out of the pulley. Have you ever had this issue? Also nice build !! Looking forward seeing your build. Before going max flow on the head check out some forums cz max flow on the bench dosent guarantee performance.. you need air velocity also. There is one guy that supplies itbs that he also does porting on cnc with proven results.
@PenguinMotors
@PenguinMotors 2 года назад
that would suggest to me something is bent or out of alignment, my guess would be an issue with the tensioner, that can force the belt towards the back of the cam pulley. i agree a small flow increase does not always give more power

What type of qautre mile times do you get and what's 0-60 like, just trying to compare if its worth me doing an m54 swap or going down your route. Will be for streer use mostly. Would be amazing to see the car in action.
@PenguinMotors
@PenguinMotors Год назад
No idea on quarter mile or 0-60 as it’s circuit racing car so it’s setup to corner, traction off the line is poor so it’s never been down the quarter or done a 0-60. One of the videos does have some on board footage from the first half of a race at Thruxton

Without opening it up your never going to know. If the car or engine haven’t been messed with it’s unlikely to be a 2.7 as the only bmw made 2.7 was the eta engine which as standard doesn’t have a 885 head

Nice build for m20. I am also going to build a 3.0 M20 with 288 camshaft and target compression ration is 10:1 for daily drive , would you please share detailed information about rod and piston spec. Or could you suggest build information? Any reply would be greatly appreciated.
@midnightzero2173
@midnightzero2173 2 года назад
You can spec these from ireland engineering. If you want to go 3.0l You'll be looking at 86mm bore and up which is getting close to the limits of the M20. Rod length for an M52B28 crank is generally 135mm. I built a 2.85L stroker, 84.5mm bore, 12:1 compression (Or thereabouts, slightly lower due to thicker headgasket), 288 schrick, ported head with oversized valves with 40mm throttles etc etc and it made around 240hp at the wheels on Australia 98 octane fuel.

I ran Molnar 135mm H-beam rods. Best bang for the buck in my opinion. Comes with ARP bolts as well. I got 86mm wisco pistons from metric mechanic. They have massive valve relives so now it's a non-interference piston. I was lucky to find a euro m52b28 crank. Has the smallest counter weights and this weighs less. It has an 86mm throw. It's a stout motor and hauls hard. Running megasquirt with a fully custom new harness. This has so far been the biggest challenge. Lots to go over and sort out with tuning and de-bugging. Its expensive, a great motor to learn on, and has a great final feel. It's certainly more special then a swap IMO. Just be prepared to pay a lot more then a m52b28 swap for similar power results

i run an emerald ecu, sorry i cant remember what the injectors are, other than they are terracotta colour and emerald supplied them after i had issues with other suppliers. but as long as you don't use Chinese junk , any 250-300cc will support anything a naturally aspirated m20 will ever need
