bmw e30 m52 stroker high compression first start up

m52 high compression stroker first start up! fully balanced, m3 cams, 540 maf, 5 speed conversion, and some headers, its a working progress.

[@mye30m50]

i used a 328 crank and rods with 325 pistons and block. it makes the compression ratio go up to 11.25, and the 328 crank is also forged.

[@GrauHer]

It sounds like 2 Harleys together, hehehe

[@XCracer15]

I know everyone else already said this but I'm excited to see what comes out of the dyno and if you have a build tread, a link to it would be very much appreciated but if not...make one ;)

[@mye30m50]

the head has double valve spring with m3 cams, but if your gonna do my set up it wont be good for boost because of the high compression. and you switch to manual!

[@XCracer15]

and @TheBimmerfan you guys might be confusing the whole engine for just the m50 intake manifold. It's a very popular m52 mod to put them on the m52 header/block, provides much better airflow but what do I know, you could be correct as well.

[@mye30m50]

its a 2.8 with the obd1 conversion it is still a m52

[@mye30m50]

@bimmerbum1 im using a 2.8 crank. my displacement should b closer to 2.8 - 2.9. im running 91 octane, witch is the highest i can get in Ca, for pump gas. i will try to get a dyno run here shortly. :)

[@mye30m50]

@nigelfoley1985 the throttle body was the same. it drove fine with the stock ecu, but after i put the chip and knn air filter, i notice a big difference. i want to go to the dyno in the coming month, so stay tuned.

[@LcstRx97]

m52 has the oil cap in the front, m50 in the the back

[@lyeszakariaimouche7644]

I did the same but with m51b25 crank in non vanos block...a stage one tune and s50b30 euro exhaust manifold and injectors running on 3.0 bar with 3.64 diff and 6speeds gearbox Its very fun to drive have never been on dyno but i guess its arround 200hp

[@TheBimmerfan]

Have you read what I wrote? I said nothing about M50 manifold because I know that M50 manifold can be swaped on a M52 engine. I said that oil cup is at the back side of the engine, where the M50's is and the oil filter housing is a m50's one.

[@mye30m50]

@MetalicB0x . its a work in progress, but it's just enough to get it running,

[@mye30m50]

i was running a Turner m3/cams chip, but i want to get a custom chip made on the dyno for it.

[@mye30m50]

kaxa523. not sure, gonna dyno it here shorty. will have a vid of it also.

[@rjteeter]

Very nice now get that cooling system hooked up =P

[@mye30m50]

@nigelfoley1985 no problems what so ever. its close but clears everything.

[@e30tim]

that's a beast

[@JumboJet888]

Where can i purchase this stroker kit? Have m52 engine

[@bryantmatthews93]

Sounds like a rotary

[@MrVoycer]

I'm building one of these, which cams are you using?

[@Munky332]

Just got a '94 4door 325i thats beat up, looking to rebuild/stroke the motor, possibly delete VANOS and go megasquirt, and turbo it (diy build). so this is just a 325 block/pistons with a 328 crank? what about the head? i also have an auto, not sure if i should replace the auto with a rebuilt one, or swap to a manual. Most of my experience is with mustangs, so this BMW stuff is new to me as i dont know the limitations.

[@catuned]

@sethum1. m52 328 crank and rods with 325 pistons.

[@mye30m50]

they sure do!

[@kirstankairan]

do the m3 kams just fit in ?

[@goheat77]

I have the same setup but its 11:5 compression m3 cams. How much power you think I will see? I'm still trying to get it started and then beak in the motor after a while of driving, I hope to dyno it. What do you think my power would be?

[@trevorjaster4072]

So howed it go

[@davidsilas6590]

Hi guys i need help,i just bought engine m52 for my e30.But the engine can crank but there didnt have injector pulse.There have postive currento but didnt have negative current pulse same goes coil plug also.I already changed crank sensor.Hope u guy help me thanks.God bless you

[@Zeekbdos]

NIce now lets see her run!!! (euromuscleog)

[@FullGarageYT]

11.25 COMPRESSION? EVEN STD M52B20 IS 11:1 WOW

[@OrangeFiero]

Just because it has an m50 intake manifold, doesnt mean the block, head, crank, pistons, and rods cant be m52.

[@randynavarro5471]

you running the M50 manifold?

[@t1kss]

how much are you planning to get power out of it ?

[@GaGracing]

what is the setup of internals? only m50 head? what ECU? piston are from m52?

[@GaGracing]

Oh, pistons are from m50 vanos or nv? thanks :)

[@mye30m50]

m50 vanos pistons

[@GaGracing]

mye30m50 Whats the piston valve distance? any dyno numbers ? :)

[@mye30m50]

1jamaicanlovrboy. ya it's up and running good, i got a turner chip and a knn filter. let's just say that this shit screams, especially when Vanos kicks, i pulls hard.

[@TschtschenBuarz]

Hov compresion have it. 11.0 to 1

[@5Toesss]

Build thread..?

[@Findmealife]

Dyno... Stay tuned. Heh.

[@kaxa523]

how many rwhp does it have? :)

[@TheBimmerfan]

This is a M50, not M52

[@Euphorica]

dyno it?

[@fladoodel]

obd1 conversion m8

[@TheBimmerfan]

What C/R?

[@MetalicB0x]

lotta stuff isnt hooked up to make it driveable

[@zepyoor1234]

How do you lower the compression?

[@onomikeono4181]

M54b30 pistons and rods

[@mortadachevy6031]

u should run higher than 91 octane like 98

[@mortadachevy6031]

Where i live in Lebanon the lowest octane rating is 95 and highest is 98 it goes for 2.5$ a gallon which is pretty cheap for that rating.

[@mortadachevy6031]

Im in Beirut Lebanon its in the middle east my friend. I have an m50b28 its boosted i run 98 octane and never had a problem with detonation.

[@mortadachevy6031]

Nicee u gotta get a thick ass head gasket i know a guys that got mine from Sweden. They run wepl over 700hp on a stock bottom end over there and they are very reliable.

[@mortadachevy6031]

Good luck with that do u have an Instagram account i could follow to watch your progress. mine is mortada.e34

[@Bmwfreak68]

A hot girl named Kirstie asked something technically ? Marry me.

[@YalbertJN]

thats a M50..

[@rayol82]

no its a m52

[@theyego]

rayol82 yeah its m50 !

[@fahrvergnuegen]

b3_qu!eT M52, it has the Vanos hump at the front. But he is using a M50 intake manifold.

[@ubergama30]

m50 can have a vanos hump too.. what tells u this is most likely m52 is the plastic valve cover

[@westpizzle4744]

M50

[@vlad-felow]

this is not M50

[@sk8aboijosh]

That's not an m52

[@mye30m50]

its a 2.8 with the obd1 conversion it is still a m52
