boring out too 84 mm for new bores. Then fitting M52 crank and rods.

[town325i]

is there any difference in the cylinder from a m50b20 to m50b25?

[Dezzy]

They are slightly smaller.

[town325i]

They are slightly smaller.

whats smaller the valves? do they have cut outs for the piston like on an m20?

[Dezzy]

Bores are slightly smaller and blocks are the same it think. I was going to go down this route before I decided to bore my B25 out to 86mm instead.

As I understand it all that's needed is to take the B20 out to 84mm and new rings. Dan will let you know the in's and outs.

[DanThe]

Chap I sold a 2 litre block to recently reckons there is more different than just the bores

[Dezzy]

When we were talking about it mate that's the way I was going to go.
If they were the same year maybe the same no?

[town325i]

ive messed up there i ment cylinder head i need to read what i type

[Dave_M3]

Good deal got there!!! I always wonder how people feel when something ends up selling for so little and know the new owner will be round to collect it soon while thinking it should have made so much more


With Dan 5 mins up the road, you should have it all done and dusted in a weekend

thats happend to me before and i cant really say what i felt it was something like this ******* ********

[town325i]

ive been to try and collset the engine tonight and my sprinter van with all its seats and bog and everything aint bloody big enough so im going back tommorow with a trailer to collect it.

The engine in question is one that has vanos on it will this cause me any aggro with fitting or wiring?

[Dezzy]

Not as long as it's a runner. I am sure wiring won't be a problem for you. A 5 min walk up the road should answer any issues you have.

[Brianmoooore]

Vanos makes no difference to the wiring at all. It's just a single extra wire contained inside the engine loom, and doesn't go anywhere near the connections to the E30 loom.

[DanThe]

You should have unbolted the gearbox, that van is near fcking useless!

[Dave_M3]

Can you take the B20s to 86mm too or are they all out at 84?

I must take my M50b25 that I blew the head on apart to see if I can do something with it at some stage just for the shits and giggles as I have an M52 crank

[town325i]

it must be an early vanos engine as its got a steel block not alloy.

[Dezzy]

M52 is the alloy block mate. M50's are all steal I think?
The early M50 mine is none vanous the latter M50 93 on i think are single vanous.

At dave_m3 never you mind about 86mm bores in am M50. That's my thing

[Dave_M3]

Haha, I'll just stick with my 86mm more M42 so

At least my other 6 pot is 87mm

[Dezzy]

Ha ha 87mm? S54? I know the M3 Evo has 86.4mm

[town325i]

ive got the engine home now and im hoping i will have time to get the engine loom off next weekend so Danthe can work him magic on it and get the gearbox off it so the old clutch and flywheel can be binned and an m20 one put in its place got to make use of the new m20 clutch i have

[Dezzy]

Nice work mate.

[town325i]

it wasn't the gearbox that was the problem it was how wide the engine is with the inlet manifold on bastard thing. I'm hoping to became supervisor soon at work then i will get a new Astra van i hope as the other van are the Peugeot partner vans and they are crap unless your a midget much more useful.

[Dave_M3]

Hold strong and insist they get you a Transporter 4motion with all the Tee-de didelly-eye trimings

Haha, I'll just stick with my 86mm more M42 so

At least my other 6 pot is 87mm

Ha ha 87mm? S54? I know the M3 Evo has 86.4mm

Who knows... knowing me, I might be tempting faith and making a 87mm bore M42

I'm sure I'll make a build thread once I get a few more bits together so you can see exactly

[Dezzy]

Vw transporter or the new sprinter gets my vote too. Great bits of kit.

Dave I look farward to seeing a build thread. Very interested

ive already got a new sprinter van but its a welfare van so it got a toilet in the back with a drying room. then in the middle its got 5 seats with kettle and a microwave so there aint much space left after that
