M42 Turbo Manifolds
« on: August 17, 2010, 08:32:52 AM »
Hi Guys,

This my first post and thought I would ask the question of what Turbo manifolds are people using. I have done a lot of searching and found a number of options. I guess what im looking for is some feedback on the differnt types available out there. My 1st choice would be the 666 fab, but as im trying to make this build to a budget it might not be a possible option.

Obiviously there are the cheaper ebay options out there, has anyone had luck with these. Ie not cracking after a few months of use etc.

I have come across the OBX manifolds which seems to be ok quality, but is advertsied for e36's. Would these fit an E30 chasis?

Any help/suggestions would be much appricated..

We're using the first 666 Fab manifold.  One key thing to keep in mind is adding some "give" or "play" in the plumbing.  We've cracked and repaired our manifold a few times, but feel it was due to tension and stress created between the down pipe, waste gate, and car attachment fittings.  I'll post pics soon of the new down pipe and waste gate attachments.  We added flex pipes as part of the exhaust.

Hi Aus-m42turbo  

please keep in mind the usa guys are LHD .. ours are RHD .so we have issues with the steering rack clearance. maybe a simple custom log type high mount manifold made from steam pipe might be the best solution .

I have been in contact with 666 fab and he has sold to some Aussie guys already, not sure how they went fitting but assume they were successful. I actually saw a rhd m20 last week fitted with a custom low mount manifold, which proves it can be done, and should be slightly easier for m42. I think I might get a few prices for a custom fabrication, and maybe even look into trying to fit a low mount.
