M20 B3x Naturally Aspirated Stroker build past, present and future

[2mAn]

I'll be ordering some custom Pistons shortly around 11.5:1 CR

Cam will be the RHD roller cam. 292 advertised duration 110 LSA 13mm lift

You're using a S52 crank (89.6mm Stroke) , correct ?

If thats true, what Bore is the 11.5:1 piston? Are you running thin on the cylinder walls yet?

Impressive

Just looked through your build.
Deeply impressed with all your knowledge. And perfect for me to study.

I have a 1987 325is with m20b30 running E85 and RHD itb’s.

Bought it with the engine built, but the former owner was not able to finish it.
Working with the tune, fuel delivery and installing vacuum system and proper air box intake.


I will study this thread closely.

Unfortunately I live slightly farther away from Rama than you, since I am located in Sweden.
Possibly the only e30 running RHD itb in the country.

Keep up the amazing work!

Epic. Good to know thanks

[digger]

fits no problem, just need a modified intermediate shaft. im getting a custom one as the stock one gets weak when you machine too much off the depth so not looking to risk it

[Bimmer_man]

I’m still dying to see if the 3.3 crank will fit in the m20.

I'd like to give You a big respect for what you've done, the research, but most of all - that you've shared your knowledge and findings here! Thank you, good luck with the build, and I hope to see more!

[digger]

cheers, have to get a wear patch repaired in the carpet near clutch pedal and fix a few broken speakers while dash is out so not looking forward to it

its coming along just a record slow pace (new job means less free time). contemplating making a new airbox and getting a new haltech E2000 ECU before engine goes in.

Hey mate, looking good. The dash is not that bad. I have done a couple. How's the new stroker build going?

[Bimmer_man]

Hey digger any updates on that 3.3 bro?

[95BMWIC]

Gorgeous!

Glad you decided to fix it..

[digger]

That was definitely done ! It carries coins and the odd nut bolt or screw...
