Silly Question, but please read

doing a cheap turbo install to my 250 2V.

using a std cast iron log style exhaust manifold and was wondering can a turbo flange be welded onto the cast iron manifold??

im only giving this a go to see how it will run and to keep costs down and all the trucks at work have shitty log style turbo manifolds and seem to work fine so was hoping for the same here, as long as the turbo spins huh

plz help

im not the best with turbo's but. you can bolt/weld anything on there you want but the whole name of the game with a turbo is flow. so i would think factory manifolds would be limited. maybe make a flanged tee in between the collector and pipe. would be easy install just to test.

yeh its just a fit and fiddle and doin it on the cheap to see how she will go.... least i know that can weld to the cast iron

anyone have a 2nd hand turbo for sale cheap for this experiment?

Rather than weld to the log, make a short adapter 1-1 1/2" high. Flange to match manifold on bottom, flange to connect to turbo on top.

Unless you are already an experienced cast iron welder, don't expect good results. This is NOT the time to learn to weld cast. Brazing would be better, but again, this is a poor time to learn. A fabricated adapter that you bolt on will be much more likely to succeed. You won't get maxumum efficiency using the stock log manifold, but I think you will be pleasantly surprised at how well it works. Good luck and keep us posted.

We could not get our American cast exhaust manifold (200 ci, 1965) to work with our OZ head. This was because the shape of exhaust ports 3 & 4 of the American cast exhaust manifold are too large to seal with smaller ports of the OZ 2V head. This is also why the exhaust manifold gasket for the OZ head is different, and the one you can get from Autozone etc do not work.

Probably not for a turbo manifold. I have seen them run cherry red during a good run, that's about the point brazed joints fail. It would be possible to make an adapter out of 1/2" or 3/4" cold rolled steel with the manifold bolt pattern and turbo flange pattern. A machine shop would charge around $50-80 probably.
