is this possible?
 

I just bought a steel log type manifold for my b18c jdm civic., my turbo is a t3 the problem is the flange on the manifold is a t25 can a weld a t3 flange over the t25 flange but then it would be restricted 1/2 inch vertically and 3/8 horizontally. The way the manifold is constructed I cant bore it out the ponly thing I can do is build a new box coming of the log to the flang ( bigger and weld the t3 on that lots of work ? any ideas can I use a mig? how thick steel?

Sounds do-able.Post some photos so we can all see what your talking about.You need to watch it doesnt hang the turbo to low though.

The Nissan t25's that were on the 88-89 300zx had T3 flanges on them. You may find a blown one or just the turbine housing, and use it.

why dont u just buy a T25-T3 adaptor for ur manifold? I have one but its the other way around. Works great too.

how can it be the other way around lol? cant you just put it on the othre side :S

Re: is this possible?
 

It would be very easy to cut the flange off and weld a new one on. If you can't do it find a regular old welding shop
