Which engine transplant?

[GrindCulture]

M50 sounds perfect for what you want then really.

[blackcountrybimmerman]

daily = m42,m44 chip & pan filter =good mpg
and pretty good fun

I take it you're into the straight 4's magpie....

In reality these engines are only giving 20PS more than the one I already have. Is it worth it?

Opinions?

[GrindCulture]

Yes, broader power band, more torque, better economy.

[Cloud]

I am, it's still in the build stage, but conservative power estimates for when its finished are around 260 - 300 horses. If I still think it's gutless after that then I'll just tune it more.

What's the plan?

Power upgrades: 2.8 M20, cold induction, ECU remap, seriously racing cam, sixbranch, head work, ITBs, lightweight pistons and pulleys and driveshafts and thangs. There's a bit more than that, little things I don't understand, but my mechanic friend is going to experiment with. If it's still too slow "tune it more" is whack on a supercharger.

[blackcountrybimmerman]

OK, to hit 200hp.

What would need to be done to the M20?

[GrindCulture]

I doubt 260-300 bhp is possible with a N/A 2.8, a guy on here and a hugely expensive 3L build that was just about 260bhp.

[Cloud]

What would need to be done to the M20?

2.8 stroker + live mapping is the best way to get that

at what cost?

[blackcountrybimmerman]

I don't know what cost mucka...

Let's say money isn't the issue, it's down to opinion and the best way to achieve the goal.

no mate,i was asking cloud

[Ziggy]

M30 suits me fine... but if I was starting it again now I'd probably be braver & go M60

[blackcountrybimmerman]

Sorry, watching TV aswell. Didn't read the post properly.

BBC3.

at what cost?

As mentioned earlier, I have a mechanic friend who can do most of the work. ITB setup is going to be funking expensive, the rest is going to be a few hundred here and there. Most of the cost is with the other parts, suspension and brakes. If I can keep the whole build down below £10,000 I'll be pleased.

do you have a build thread?

I took a big gulp when I read that....

I will do all the work either myself or with someone who doesn't require renumeration for their services.

TBH I think £10,000 is a lot of money to throw at a car. I like my motor, but I don't like it £10,000 much.

If you want to spend that much Cloud I salute you, the E30 is an iconic car.

But if I were to even think about suggesting that to my other half, I would lose my family jewels.

A V8 will fit?

[Cloud]

Nope.
Still haven't got around to buying a camera. Meant to get one in the January sales. I can't see there being much interest in it either, it's just cleaning some grot off some valves, getting ridiculously oily with the crank case, and some plastic induction tubes.

It is, it's a really silly amount to bung on a car which might end up wrapped around a tree at any moment. But as it goes, I don't have a family, friends, no children, and no hope of getting any of those things ever, so the car is kinda the substitute for all of that. Some people can say they built a business up, some that they had a family, some that they bought a nice house in the South of France. For me, I'll have my E30 grin-machine. £10,000 is a lot on a car, but it's quite a bargain as far as mediocre lifetime achievements go.

Cloud,

Do not think for one minute that I'm knocking you. What you do with your hard earned is your business...... fair play to ya. Like I said, I salute you for commiting that much time and effort to it.

6 cylinders make a nice noise.........mmmmmmm

Well,
the Alpina C2 2.5 engine makes a pretty fantastic noise. The standard M20 is a lovely musical instrument though, even through bean-can fartboxes, it sounds gorgeous. One of my favourite sounding engines by far.

I also like the noise the M30 makes! quite similar to the M20

No, I know, I understand. Thanks. I'm just highlighting the reason why for me it's acceptable, even though £10,000 on an old car isn't really sensible.


I'm using an M52 crank for my 2.8

M52 is 20 more bhp than an M20
M52 crank in an M20 gives 25 more bhp

M52 was restricted by bmw for some reason,insurance i think.

put the M50 inlet manifold on and remap and your snarling at 220bhp,maybe more!

it has an alloy block too

[blackcountrybimmerman]

On some of the later engines, are some of the parts standardized? Are you able to interchange between engines?

[blackcountrybimmerman]

These are the sort of threads I like.

Lots of information appears from them...

I'd say it's less so with the newer ones. The M10 and M30 engines were built from the mid 1960s through to the 1990s, so they really became the "standard" engines. After 1992, it seems that BMW went berserk with making new engines, there's a huge variety, but I'm not sure how much technology they have in common, or what parts are swappable.
