+1

nice. any more pics?

have you got anything planned for it?

Hi yeah i only have had it about a month now.

Don't no to much about it.

would be intrested in details of the 2.7 aswell if you have any?

James I'm relying on you knowing all there is to know about 2.7s

I was told it was done by the owner before the one i got it from he worked at BMW and did it him self.

Galvanised 318is comes to mind

You lost me there mate

Bull Every man and his dog says its a 2.7 when they dont know much about e30s

What you try to say mate that am full of bull and its really 318

Joke is wasted. Its a 2.5 but plenty of clueless sellers say its a 2.7 . Ps i am using my phone

Unless it has proff it's a 2.7 and how it was achieved, anyone new to e30's can be fooled into believing it's "had the conversion"

Most common seen on ads is "bored to 2.7"! mistake no.1. You stroke them to 2.7 not Bore them.

Next up is the head marking where it states 2.5 /2.7. Must be a 2.7 then? Wrong. Some factory 2.5's came with that head.

You need to go back to the previous owner and find out what he has done to get it to 2.7.

Or put it on the dyno and see what it's making.

hi everbody
im the previous owner of this lovely e30 and i think i made a mistake by selling her as 2.7without the proof as i bought the car the way it is just now and previous owner said the conversion done by him and he didnt had any proof but after i had a nice drive in her and seen the power i believed him as i had few e30s now and she was definitly more powerfull then the e30 325i i had
i never put her on the rolling road
and i only sold her as i lost my garage and i would say she was the cleanest e30 i had

I'll be doing a 2.7 conversion in the near future, I'll bear in mind the proof thing to make sure my car doesn't end up with a thread like this. JBH will keep me right

Thats it booked in for the rolling road to see what its putting out.

Better take some photo's of my 2.7 before it goes back in, then.

Mind, it is only an eta/731 so it probably doesn't matter much.

still worth doing Stuart

but I think your like me.. it will be with you for a very long time.

I can not wait mate hopefully we wont be dissapointed

I'm not so sure James. I still can't help thinking it's time to move on.
I've got to get it mobile, whatever happens, but I'm expecting one huge disappointment. TBH, I don't think that even if I'm happy with the way it drives I'll ever trust the car again - I'll always be waiting for it to let me down. Regularly running up and down the country as I do, a car that doesn't instill confidence (or, worse still, isn't reliable) isn't an option.

.... Or am I
a) thinking of another town/city?
b) mistaken?

John Clarks in Aberdeen(& Dundee) are the only Scottish agents for Alpina Stu, so your correct on that point.

As to whether or not,they carried out any work for Sytners North of the border,that I am unable to confirm.

I do know they(John Clark) have an alledged, good relationship with Alpina back in Buchloe

OK so its going on a rolling road soon what should be the outputs if its has had the conversion and what would they be if it has not had it the conversion

171 is factory output

a well sorted 2.7 should make 200bhp but it all depends what conversion it is, an eta conversion using a 320i head may only produce that of a 2.5 but with more torque

very nice motor mate

Factory 2.5 is 171bhp. IIRC the Alpina 2.7 should make 210.

What's the relationship between torque and bhp ?

ha ha, i was gonna buy that but decided on a project instead of an already made 1

Thanks for that info

I get the impression that there is a lot of "guesstimation" about 2.7 power outputs. The only eta2.7 I'm aware of seeing a dyno sheet for is Daimlerman's. That one made 178bhp and had peak torque of over 190.
Also, there are a lot of variables in the way people choose to build their engines. For instance; my old 2.7 had head work (325i valves and ports to 325i size/shape) and allegedly made 213bhp with a BTB manifold and Cat273 cam. I never saw any dyno plots for it, though.

In a few weeks, I'll post figures for my new one, once it's run-in and been remapped.
It's been built for torque rather than top-end, balls-out, power - basically it's a 2.7 bottom-end and 2.0 top-end with a 325i cam and a very light flywheel.

Would be nice thave some facts about these strokers. I would plan to use the 320 head as well

It was a guesstimation, i was looking into having a bash at building one a while ago.

do you have a pic of the engine bay mate?

Nice car tho
