I'm working on it. The old threads were M8-1.25 and they were stripped out pretty bad. So I drilled them out and taped it 3/8-16. Then put some high strength red lock-tite on some grade 5 bolts and torqued them into the new threads. Let it cure for a day. Then used a hacksaw to cut the bolts off. Then a file to get them flat. Now I got all metal again. :)

C-clamped a T3 flange to the manifold, then used a drill bit to transfer center marks (need a set of transfer punches...). Picked the one that would be the hardest and did it first. Drilled 1/8, something bigger, then 5/16. Then taped it... Sucks tapping cast iron/grade 5 bolt. Dissimilar metals FTL. Hard and slow, but it's working. Gotta get some thread cutting oil before I do the others. STP oil helped, but ain't the same by any means.

impressive:)

wow, that actually looks pretty good. good luck with that, it looks like it will work.

Yeah, I'm pretty sure it's gonna work. Bought a damn set of Craftsmen taps and they're shit. Things don't have a center mark on top to steady the tap with a center. Ended up taping the first hole slightly crooked as I was eye balling it. Got another hole drilled, but I'm gonna have to buy a real tap before I do another. I want it right.

I'm glad it is working for you. We did basically the same thing but from a T3 to a T2 on our Swift GT manifold:

It held fine.

Finished the holes for the turbo to bolt up. Cutting fluid FTW. And changed to bolts. I drilled the heads of the bolts so I can wire them together. My bolts will NOT back out. ;) Will drill and wire the downpipe bolts too. Now I'm starting on adding a wastegate port.

Tim- Looks good, and glad to hear.

looks really good man.

Looks great. Are you going to mill it for a flat surface?


Turbo Tim, Did you say you turbo'ed a Gt swift. As in Suzuki, or metro with the 16 valve motor? I'll pm you.

kotomile 12-16-2008 12:29 AM

Did I miss it or did you already say what you were going to do about an EWG?

patsmx5 12-16-2008 09:58 AM

The external gate setup will mimic the S5 manifold setup. About to start on that right now. :)

I'm thinking about switching to bolts and safety wiring mine too, lol.

Ceramic coating looks super cool (may hold some heat in the turbine/not radiate as much)

don't forget to put some of the rutland gasket cement works perfectly. looks like this

Flat surfaces don't need gaskets.

Yeah, my welds ain't pretty. But they'll work I believe. Better than I did on my exhaust system, and it's still working...

Is there a difference? It was a legit Swift GT. Very very fun.

This build is going awesome Pat!

thats because it is big lol...at least when compared to other turbo's being used here

viperormiata 12-17-2008 07:17 PM

Looks almost as good as my FM3;)

I tell you what man, that is true craftsmenship:bowrofl:

patsmx5 12-17-2008 07:44 PM

This down pipe is gonna be a BITCH. Fuck. Started building one and it ain't gonna work. Gotta start over on that. Oh well, I'll get it. Probably gonna have the waste gate dump back in pretty soon for simplicity over performance. Just want it done at this point. I utterly HATE doing anything with exhaust.
