Hey!

While doing some hard driving in the mountains this weekend, my MKTurbo manifold cracked… causing my downpipe to crack.

I have cracks running on the top and bottom sides of the turbo flange and a crack on the 1st runner.

I’ve already sent an email to Lars, but was wondering if anyone had any other ideas.

Will another manifold fit or get close to fitting? I’ll already have to get the downpipe welded up.

I would like to eventually track the car a couple times a year, but wouldn’t this just happen again?

I do have the softest Innovative poly motor mounts which might have contributed.

Just trying to weigh my options (hopefully the most economical). Between finding a different manifold, buying a replacement MK, or getting it welded up.






TIA

 

Your timing locked at 10° or something?

 

I am on the 4th revision E-Tune with digitune since I have an FM221 ecu. I would HOPE Digitune would spot something in the logs I’ve been sending if timing was off.

For the previous 8k miles, the car was running on the smoothest looking tune but the timing tables look similar.

I also drive the car quite a bit in Charlotte which does not have the best roads.

Ran one of these cast tacotaco manifolds for almost a decade. Even cut into it, welded on it, and added to it. Never cracked. Went 6.50s in the 1/8th mile with a modified version of it.

 

Did you use a custom downpipe?

The Mkturbo turbo flange is between the 1st and 2nd runner to give enough room for the vband. I was trying to salvage the downpipe.

 

Yes custom booger welded downpipe. Even the manifold eventually became custom to LOL...
