What motor for my soon-to-be-starting project.

[GrindCulture]

Hope to soon be picking up a good rolling shell to start my project. Just trying to weigh up my options as far as engines go. I'm mostly torn between a tinkered M30 and an M60, but not ruling out things such as M50s or turbo M10s.

Looking to get about 250bhp at least, but cost is also an issue, although not sure how much of one at the moment. Any options would be grand! Cheers.

Rebuild a M52 B28 into the earlier M50 B25 block (same bore/height) and get it on MS with the 2.5 inlet and that could see 230 bhp, if you change the cam's it could see a little more...... if you ever get bored with that then Ant sells supercharger kits


Now then... wheres that lotto ticket gone

[FormerMember]

There's one guy running M50B28 with wilder cams and MS, dynoed ~265hp..

It all depends on how much are you willing to pay and how good engineering skills you've. M30 is a lot better than M20, and much nicer to drive than M50. M60 would be badass

[Alex]

turbo m10 !!!!!

There is loads of talk about turbo m10s on here but i cannot say ive heard of anyone doing one or seen anyone do one

[GrindCulture]

I think M60B40 would be my ideal engine, 280odd bhp from the crate. However, money's gonna be an issue, so maybe another day...

M50: Don't think I'm going to get the power I want from the amount of money I'm willing to spend, sure it'll be more economical than the other engines, but it's not going to be driving every day/week anyway.

So, it's now a toss up between turbo M10 and M30. Fritz's Bits it just up the road from me, so any mounts/manifolds etc. should be pretty easy to come by. Decisions decisions...

[Alex]

i did have an m10 sat in a mates field you could have had but its now scrap

[JGG1]

Are doing the work yourself? No idea of your mechanical skills but the m30 is a piece of piss and plenty of bang for your buck!

I would start there (as I did) then if its not enough just modify it, then if thats not enough just turbo it!!

Where are you in Devon mate?

[GrindCulture]

I will do most of the work myself yeah. Both the M10turbo and M30 should be simple enough , even easier if I get a car with an M10 in already, then I can just emulate the 2002turbo setup and tinker with the boost levels I hope.

I'm in Cullompton by the way, J28 off the M5.

After having a chat with one of the guys from Fritz's, a triple-carbed M30 would be good for 250+bhp fairly easy with a good manifold. Not sure what figures I'd expect to get from a turbo M10 setup, the 2002turbo runs 170bhp, but surely that could easilly be topped. The M10 should cope with fairly high boost levels on stock internals. Anyone have any ideas?

[maxfield]

M10 engines are strong as!!!

A triple carbed M30, Christ I dread to think of the fuel consumption

Me too, but imagine the sound

[stonesie]

IIRC the brabham F1 car engines were based on M10 blocks... 1.5 litre 1500+ bhp (Money is a wonderful thing)

So you could say theyre strong, also M30 turbo has been done and theyre strong old thumpers

[Alex]

m10's are most likly the strongest engine bmw have built

Hahaha, carburettors. Back to 70's, eh?

M10 with turbo makes easily 500bhp, and basically only the sky is limit with it. M10 based F1 engine made ~1700bhp with 5 bars of boost back in the '80s..
There're lots of M10 based drag racers, with S14 bits they make reliable 1000bhp.

M30 can be turboed with stock internals until ~1.2bar, then it makes ~500bhp.

It all ends up to your budget and skills.

[GrindCulture]

Apparently so, I don't know much about the advantages over the standard injection personally but the guys at Frtiz's rave about how much better the M30 is with them, plus it's apparently cheaper to set up than an ITB setup.

There's a guy on here with an E21 with a triple carbed M20 in it.

[beefy]

If you go m30 i can supply the mounts and cheaper than fritz. There e30 de copies very well made do a search for them and check the feedback.

Well, with EFI you can tune the whole rev - area, with carburettors only idle and full throttle situations. Maybe little bit aggrevated, but that's how it goes.

If you tune EFI once right, you don't have to mess with it again. Also, it can adapt by itself to different situations.
Carbs you've to tune time to time, clan them etc etc..

ITB:s are quite a lot of money, yes, but so are good carburettors.

I think I've decided to go M10turbo. I've been offered a good engine to start on, hopefully I'll have the pony to get it, even if it means not getting a shell for a while more, apprenticeship=shit wages .

After reading a bit about the race cars from the 70's using it, that was probably what pushed it for me, Schnitzer had an E21 315 turbo pushing out 400bhp

really glad to here you are doing an m10 turbo, its about time someone on here did an m10 turbo, or have i mised something

[GrindCulture]

I've not heard of anyone here doing it, but I've not been on that long.

Watch at about 3:10, that's what I'm looking forward to

It's going to be slow going, just need to start getting the bits together and developing the knowledge to be able to pull it off.

[maxfield]

It's a toss up between this and the S14.

Both share the same blocks.

A turbo M10 is definitely something I would like to see on here.

[Alex]

use a 316 m10 and fit twin carbs, will sound pretty cool

[Alex]

that m10 in the video looks

fast as F**k

[GrindCulture]

All on stock internals too apparently.
