745i M106/M102 (M30) turbo engine

[GarrettM]

I went to check out a euro 86 745i Turbo. Now the guy didn't know much about it except it needed a turbo. Wants 1000 for the whole car. I read these are based off M30 engine? If so, will it bolt up to a 3 series? If anyone wants any info on the car let me know. The guy also had an 84 I think 745i also a turbo. He just bought a 94 750iL so thats why hes selling the 745i's.

he should kept the 745i that thing has some long legs for its time and not to many came across the pond, I'm sure there is a 745i owners group e38.org the e32 section or bimmerboard.com they are 7 heads thats for sho!

if your saying the745i (m30) turbo parts bolt up to an 325i (m20), NO

but id like all the turbo parts to make my 535i a turbo:p

Oh yes it can be fitted:



It's 3.2l M30 engine with turbo. Only fitted to E23 745, it's really strong engine, oil-cooled pistons etc etc.

Worth buying, these ain't found in many places.

I meant swap engine. Would it be like any other M30 swap?

Basically yes, only problem is the turbomanifold which may need modifying.
And if you want to tune it more then you need bigger turbo, IC, better turbomanifold etc etc..

But it's same M30 as the others, only difference outside is the manifold, turbo and IC.

that looks like a M106 (m102 had a different distributor), its been fitted with a new head at some point too.

now if only i could find that turbo manifold id be a happier person.....unless theres a company that'll make an ex. mani thatll fit into a e30b35.....any knowledge.....anyone????

In 745 the manifold is located "underside" so i doubt a big turbo will fit there, of course those original little KKK's fit but..

Alpina B10 biturbo could be one option also, biturbo 335 would be cool :)
In those the turbos are also under the manifold, though :-/

Best option is to make it by yourself / get it made so you'll get exactly the manifold you need.
Here are some E30 M30 turbo manifolds for sale time to time (forum / säljes) but those guys are located in Sweden so it could be a problem to you... www.pure-pf.com But anyways lot of kick-ass turbo E30:s :-)

thanks man! i recently saw a couple of pictures i think on this site where a guy used a 745 mani but flipped it upside down so the turbo's up and closer to the front of the engine bay.....so it kinda intrigued me...especially with the tight space....thanks again tho:)

[Garageaholic]

Srsry? I have writeups on how i did it in my E30...

[bimmer_adam69]

mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm mmmmmmmmmmmmmmmmm
i will find your write ups frank! and i will drool haha....i know i shoulnt be so lazy....:p

[Madhatter]

ill send you one if you want, no idea what shipping would be worth :D

The K27 isnt exactly a small turbo either, just in its current trim it just doesnt have the potential for big horsepower.

[bimmer_adam69]

send me a 745 turbo mani?????? :Dor is this directed to someone else?????:(

[Madhatter]

yeah if you want, cast iron+international might be a little exy though :D
