What engine?

[coldo]

Just a quick one, can anyone tell me what engine is in the late E30 316i 's?

Just that ive been doing a bit of reading up and found that some are M10 engines, and some are M40? Is this right?

Also, some are 1600cc and some are 1800cc? (its getting confusing now )

Finally, some are 102bhp, and some are 90 bhp!?

So, basically what im asking...

What engine should be in a late 316i? M10/M40? 1.6/1.8? 102bhp/90bhp?

Response is much appreciated

The facelift was in 1988

Pre facelift 316 (without the i) was a 1766cc carb engine, 90bhp
Pre facelift 318i, a 1766cc injected engine, 105bhp
Post facelift 316i (with the i) was a 1596cc injected engine, 102bhp
Post facelift 318i, 1796cc injected, 115bhp

Hope that helps

Forgot to say pre-facelift 4-pot engines were M10 and post-facelift were M40!

[coldo]

Aha, youve told me what i wanted to hear.

Thanks very much for that!

Another quick question... how tuneable is the M40 engine? What gains are to be expected from the usual bolt on mods? (chip, BBTB, exhaust system/induction kit etc..)

[Zayyan]

To be honest I've been told the M40 isn't worth bothering tuning.

I've got a 316i myself and Zone chips aren't available for them (only the 318i ) but I'd consider a BBTB in the future if I have the funds to throw at such things, I've heard chip and BBTB are definitely the best mods.

I've gathered that the standard airbox is pretty good so an induction kit's a bit of a waste of money unless it's heat sheilded.

The M10 is good for tuning.....you can bore the 1.8 out to 2.05 litres and with a lot of other engine work 200bhp is possible!

[Zayyan]

Forgot to say pre-facelift 4-pot engines were M10 and post-facelift were M40!

Not forgetting the post-facelift only 318is which is the M42

If you're considering a 4-pot E30 you can have anything you like as long as it's a 2-door (and not a Lux if it's a 318i) for the same insurance money (i.e. they're all in group 12), so think carefully about tuning if you're planning on it as the M10 engines respond far better to this....

[coldo]

Are there chips available for the 316i? (not neccasarily (sp) a Zone one?)

Am i being unrealistic at looking for 125bhp from the 316i? Without some form of forced induction?!

[Zayyan]

I'd say a 125bhp 316i without spending serious money (and it's seriously not worth it) is very unrealistic.

If you have a healthy engine then you can expect 110, maybe 115 from a BBTB and a chip but that's what the 318i pushes out so not really worth it....

If you haven't bought this 316i already read my post about considering the M10, I think you might've missed it

I did miss the post, saw it now, and see where your coming from!

Thing is... im not right into my BMW's/E30's etc etc... im a ford nut to be honest, just i noticed this e30 for sale, (dont get me wrong, i like the e30 shape alot) and thought, aye, if its clean and solid, ill have it.

Ive been looking at my options for a while now, and to be honest, this is the only E30 coupe that i could find advertised for sale within 100miles of me! so i dont have a big choice when it comes to models etc... and, like i said, its only a tempory thing, untill i can afford to run/insure/buy myself a series one escort RST

But who knows, i might get this 316i, and be converted!

As for tuning, ideally, i want to be able to see off the local goon squad in their corsa's without the risk of trying, then getting made to look silly by big dave and his 14 year old missus

Anyway, im going to view this car on saturday, so hopefully by monday ill be an E30 owner, even if i do decide i want a bit more power/different car
a few weeks later

Sorry for the big read folks

Your after a series 1 eh coldo ;) much you offering

Hmm its a little more complicate with m10's Zayyan...

Facelift was actually late 87, but this is bodywork, ie converting from metal bumpers to plastic bumpers and bigger rear lights.

The injection 1596cc engine didn't come in till late 88, so there are some facelift cars with m10 carb engines in them.

Easiest weay to tell if its carb, is by looking for the big round air-intake lol!

M40's also have bigger fan shrouds...and the radiator has the expansion/reservoir on the side whiloe m10's its on the top.

Oh and the Max ever made from a m10 is 1400bhp...you can turbo the sh!t out of them

[Jos]

Anyone do a turbo kit for the m10 to take it to 1400bhp?


Think I might hold on to my little M10 1.8 then (sitting on the garage floor), might make a nice rebuild project at a later date, something to drop into a track car maybes..

[Gwynleym10]

The 1400bhp, prob had nothing the same that is on stock m10's though....!

It being a four pot meens it will always handle better!

Go to

and type in m10 turbo to the search...loads of stuff!

Also this little beut in my sig pic...mmmmmmmmmmm

IIRC, BMW built them using used M10 blocks. (something to do with relieving of stresses in the metel).

D'oh

I knew about the facelift cars with carb engines, just forgot

Does that mean you could get a facelift 318i with the M10 in?

I got confused as I'm pretty sure the change from high to low compression for the 6-pots was as simple as pre-facelift = high compression and post-facelift = low, and presumed the 4-pot changeover time was the same

[Brianmoooore]

There are definitely post facelift cars with the carb M10.
I've just been taking fronr panels off one.

[wayneE30]

yep i own one
