[gromgsxr]

was looking for a bit of advice on making a m20b27 turbo iv got hold of a eta crank pistons and rods cheap and was thinking about using the 325i block and head and pistons iv read the wiki articul and was wondering if anyone has done this and can maybe give me some tips hints that may stop me making my life any more difficult cheers

[fowler]

off topic you started sorting yours out yet ??

[ross2009]

na mate aint touched it yet think ill get xmas out the way first then look at it but i think im gonna go 2.7 so ill have that crank off ya

[fowler]

sweet well you know where i am ? could post but will cost you loads of dosh due to the weight......
you will need to get it re-mapped me old fruit.
You going nuts on it like you said on the phone ???

[ross2009]

well dont weigh no more than a diff do they ?? there what 35 quid could arrange courior
yeah i know mate thats not a problem yeah gonna go full hog mate forged rods and pistons

[gromgsxr]

yeah i know ant at a-tec he got my mates e30 turbo running and also my mate brought the project grandad off him and the black e36 cosworth on his site me and my mate finished was looking for info like what pistons to use and how much to deck the block for a low comp turbo ready setup, thought i read somewere ant had thrown in the towel...

[ross2009]

you dont need to deck the block if you did that you would make the compression higher just ike skimming the head for a you seem to have the parts for a 2.7 the eta cranks 320i rods 2.5 pistons and a 2.5 head thats it mate

ant has thrown the towl in too

[gromgsxr]

bolt that lot together and what sort of compression ratio would i be looking? tried to do the math but aint got the doner 2.5i engine yet couldnt work out the compression cus of the crested pistons

[ross2009]

if you do it that way i think it works out about 8.3-1 i maybe wrong on that tho

[fowler]

just take a bog stock 2.5 and boost it it will take a bar of boost and dont bother fanny around with a 2.7 if you aint got the cash as it gets very expensive ?
If you dont eck the block o 2.7 build you end up with too low compression ideally ? it need sto skimmed a little but not going to give that info away for sh**te as it took a long time to work out.
As to the topic geeza you know kevin ? yes i have replied to your PM and i know all of the cars you mention and yes i had hand in doing some of the work with Ant, yes he has jacked it in for now...
Exciting times ahead i Hope....

[gromgsxr]

that sounds good to me hopefully getting an engine this weekend, will prob end up getting the parofin out and measuring the combustion chamber cc to do the math, any ideas on things like plugs to use doner cars to get coil packs off? ignition leads, and where to get hold of a strong head gasket and bolts/ studs??

[fowler]

yep yep and yep
you need arp stud or bolts your choice
STD head gasket (weak point so it goes tits up it can be replaced easily) BMW only
engine will need a refresh before boosting new oil pump, shells etc.
Its all down to the builder IMHO.....
Info is not free i am afraid...

[gromgsxr]

good thing i work in a motor factors so cheap parts, and ur not gunna give any friendly advice on my project lol? for free

[fowler]

All info gathered was at my expense lol na i will give most info but some stuff you have to find out for yourself i am afraid...
I have guided Ross up ther on his build and it was going great unit till he has an engine issue..
But 2.7 turbo is hassle trust me as i am unsure if a eta crank could take the beating,
the thing is if turboing was easy and cheap everybody would be doing it....
I have learnt alot myself down the 6 years i have been doing my project. the do's and don't what works& what don't
Just do the easy route, and get a good 2.5 give it a good freshen up and turbo that but it won't come cheap and that comes from alot of hard hours grafting with a good pal of mine in sun rain snow with alot of heartache along the way.
I have now come to an end and mine will be going up for sale in the new year, as I hope some one can enjoy it as much as i have... pastures new and all that..

[gromgsxr]

eta crank is just strong as a standard 2.5i crank, was not planning on going mad just for fun, iv bodged over 10 boosted cars with mixed results good and bad. from fords to bmw to mazdas

[fowler]

well have fun

[gromgsxr]

sure i will you brake it half the fun is fixing it again

[fowler]

That is true can't say fairer than that but each time it brakes you want it to go a little faster next time lol

[gromgsxr]

to true you speaking from experiance lol

[fowler]

a very big yes

built right, an engine with an eta crank can take a fair ammount of abuse

i know of a 2.7 turbo e30 running over 600bhp, well 2 infact.

god doesn't an M20 bay look better without an afm.
