Great M70 Bi-Turbo thread

[SergeBMW]

Found this great thread while searching the interwebs for M70 turbo. Long 38+ page thread but plenty of photos of a guy putting together a Bi-Turbo M70 setup. Personally I would have placed the turbos near the front, next to the distributor for ease of installation but who knows, maybe the plumbing would be harder. This is something I would love to do to mine in the not so far future just for added HP, not to make it a rocket. Maybe having a 6 speed will be enough for me.

Great site thread, may need translator for some.

I only skimmed the surface of the thread, but I'm glad to see an M70 bi-turbo conversion in an e32. Usually those threads only exist in the e31 world or guys who use M70's in chassis swaps. Glad to see a documented bi-turbo (other than from Dinan) e32, and even the undocumented couple of Dinan e32's that are know to exist are rare as hens teeth.

Yea I have seen plenty of E30s with V12s BiTurbo but not much for the E32. There is this guy thats been racing an E32 V12 bi turbo with an E38 front end (hood,lights bumper) and it sounds great but last I saw he still had the sluggish auto trans in it. Never saw any info from him on his build.

Very old video but when it came out 10 years ago. You can see the E38 bumper, lights, and hood on the E32. Also I think at the time he lacked a proper tune because it seems to accelerate very slowly for a biturbo v12. A later video shows it running much better. There was a newer Dyno video of it by his friend.
