93 GSR Acura Integra swap to a 94 GSR Acura Integra : im looking for a manifold or can i use my 93 stock manifold

 

you can use manifold from any gsr if you have gsr engine

 

Would that be my old b18

 

The only place you should have to worry about clearance, is at the oil pan, and next to the center engine brace. As long as your pipes line up and you don't have any contact, there should be no issues. The engine blocks and oil pans have not changed much over the years if at all. I personally have used my 91 manifold on my 92 and had no issues other than the o2 sensor location, just plugged the hole.

 

That would be your old "b17" you mean.

 

No it was a b18 it was on the block

 

If its intake manifold cannot use any manifold but stock 94 up gsr
Older model b17 use different head
B18 won't work unless it's b18c1
Best to buy skunk 2 or Blox aftermarket or just keep stock gsr manifold it will fit with car besides throttle cable which u can use a regular opening style throttle body instead of reverse
if it's exhaust usually u can use stock almost any model just check oil pan clearance
