i couldn't agree more lol

do me do me please... 0871294 original reg e333 ftf

hello guy been having me a manic week :mad: right one of the blocks i have has the raised centre and the other has the sunken centre i think this may be on account of the year of manufacture i have a mag that says the early 525e cars built up to sept 1985 had a very high 11:1 compression ratio whils...

thanks for that Brian will speak to the stealer better to safe than sorry

All E30s and many more.

you wouldn't happen to know how to tell if its an old type cap or new ???

Brian that rad cap recall thing does that apply to all e30's

it seems to me the engine you took apart (sold to you as 2.5) is actually a 2.7 mate but get the crank measurements just to be perfectly sure.

318 are 4 pot.

early 325i pistons had same crown but longer skirts

hello again GUy just a thought mate like i said before i can see 3 possibles ie 323i, 320i or 731/eta conversion. have you measured the pistons to ELIMANATE as the 323i and 320i had 80mm bores and the 525e and 325i have 84mm bores and steam hole between each cylinder. cant believe i didn't think of ...

always gutted to hear about this especially being an e30 fingers crossed you get her back dude

interested also but defo need more info...

any joy with BM GUy

finally found your thread dude, no one worse at computers than me

nice pics cant Wait to see the vid

1bar = 14.5psi so 4700psi = 324.14bar really sorry about that

that's the second encounter of brain rot ive had today must be that birthday ive got coming up.

really good to hear there's a big improvement and all went well

how much did the pipes set ya back

ok mate you got 3 alternatives i can see... 323i, 320i or the 731/eta 2.7 conversion cause like sychochild said it could be an insurance cover up. best bet give bm a ring and see if you can match the crank No's up

hello psychochild i live in brighton mate

yes mate the pistons look the same but that's not to say its an eta what head came of the engine

i cant say to be fair as Ive always relied on the block code

to be sure. you say 2 small cut outs for the valves??? the 2 blocks i have here only have 1 small cut out for valves per piston. will try to put pic on for you latter

I'm no expert but as far as i no! the 2litre is thirsty on account of the 731 head BM used which can flow enough air for 200bhp hence why you can get away with using this head for the 2.7 conversion. as far as i know the best 2.7 build fuel consumption wise is when using 885 head and 325 pistons (h...

it comes down to the heads the 731 has 40mm inlet and 34mm exhaust valves and 885 has 42mm inlet and 36mm exhaust and different size and shape inlet and exhaust ports hence the 731 head is capable of around 200bhp and the 885 210bhp+ also the 325 piston has a specially shaped crown so when used with...

hello schuey could be risky as 4700psi = 108bar there abouts mate

don't mean to put a downer on it for ya mate. have you got pipe bending tools as looking at this conversion it seems to me it might pos to make the original ones fit

I'm no expert but as far as i no! the 2litre is thirsty on account of the 731 head BM used which can flow enough air for 200bhp hence why you can get away with using this head for the 2.7 conversion. as far as i know the best 2.7 build fuel consumption wise is when using 885 head and 325 pistons (he...

hello mate there's 3 m20 engines that used the 130mm con rod they are 2-litre, 2.3 and the 525e. the 325 con rods are 135mm long. however if your gonna do the job wright and use your 325 pistons like you say then you will need the 130mm con rods, 525e crank 325 or 525e block as they have the steam h...

OK just a quick thought the standard 325 power steering pump is 110bar does any one know the Z3 pump pressure

sorry mate since i moved house i can not for the life of me find my calipers

i even tried blaming the wife

but still no luck

i have however compared against another and there is definitely no difference. hope this helps... jay

don't even go there :cry: i tried a few years back to remove one for a full respray and ended up backing out and pushing it back and forth instead for ease and iam a commercial and domestic electrician by trade. some of the connections are spade which isn't a prob but most are a push fit design that...

http://www.rceng.com/technical.htm plugging the numbers into that site seems to support my arguement? they use 0.5 for the bmfc which is an assumption it may be 0.4 or 0.6 nobody can tell you which it is for any particular car, you'll need an accurate engine dyno and diagnostic equipment. Those num...

Armed with all the above who could go wrong with this conversion i certainly feel confident now, so a final big thanks for all the knowledge guys and Ian mate you truly are a legend... cheers pal

hi ian here's a pic of that manifold mate

hay you guys check out the prices of reconditioned racks at buypartsby.co.uk and the best bit is they do recon drive shafts as well

cheers schuey let use no how you get on with the pipes... jay

hi schuey good to hear the jobs a good'en well almost but ya get a bit of that!!! did you use the e30 / e36 linkage conversion??? with the Z3 rack

cheers ian... jay
