That's what Aaron's kit is. There time certs which are better. You drill out the old thread. Tap them and then screw in the time cert.

You'll probably need a 90 degree adapter on your drill to get the closest one on the firewall.

My way.:nono:

Was thinking to do the job with helicoil but did not have enough of them. So did my own inserts from bearing bronze. Outside has M14X2 thread and inside MF10X1.25 thread.

P.S used milling machine for frilling and making the threads......and lathe to do the inserts.

Dude that is super clean .I fixed mine already I took a couple hours but I got it.I picked them up at driftmotion, by the way Arons and his co worker are bad ass and his shop supra is a beast.

I understand sometimes you have to use what you have. But bronze? Bronze and aluminum sit on almost the complete opposite end of the galvanic scale. With aluminum sitting on the anode side and the most likely to corrode. Hopefully it doesn't become an issue, but couldn't you have picked a more compatible metal?

Had a discussion about that matter with my elder colleague who has a good knowledge about matallurgy and he pointed me that it's not going to be an issue since the bearing bronze alloy that we have allready has 9.5--10% of aluminum in it. It also has iron, zinc and lead in it. :wave:

But only time will tell how it's going to work.

fromgehenna, what turbo and exhaust manifold setup is that?

It WAS a china manifold but......... First I cooked it in hardening owen in 800 degree of celsius for 3 hours (to relieve all tensions in welds). Then nodifyed the wastegate (turbosmart 45mm) flange and weldet some supports. Then I straighten all the flanges and coated it whit black satin. Manifold is T4 and my turbo (Master Power MPR 474-3) is T3 so did a transition flange from T4 to T3. The flange has termall sensor place in it. So some small fab work has gone in it. Hope to get my OldCrappy running in coming summer.
