Default Will this intercooler inlet size be a problem?
I am building a single turbo kit, and the intercooler I am using has a 3.5 inch outlet to my intake manifold, which is fine, but the inlet to come from my turbo is small.... My turbo outlet to the intercooler inlet is 2.5 OD, but the inlet that it connects to on the intercooler I have is 2.0 OD...

Is this going to be a big problem? What sort of effect can this have with this sort of bottleneck I guess you could call it?

Or can I run it and still get 700 wheel....

So to make sure I'm reading this correctly...the ic has a 2" inlet and a 3.5" outlet?
Also what are the overall dimensions of the ic?

Cut the inlet off and weld a larger one on it.

Be careful cutting. All the filings that make their way into the intercooler core will eventually wind up in your engine. You would have to stuff a towel in there before cutting, or maybe use a plasma cutter.

yeah, I was considering doing that, or having that done. Just wasnt sure who I could go to, to have aluminium welded, and if they would be able to get the cast aluminium 90 elbow I would need in 2.5 OD.

You could just stand it up when cutting and let gravity keep the insides clean

Why does it need a cast 90 welded to it? Why can't you put a straight piece of tube on there and then make the next piece that couples to it a 90?

That's a good idea - or you could take the blow-side of your shop vac and put it on the other end and blow the chips out.
