2.2 with 2.5 heads?

Post by race_to_live »

I have a 91 2.2 turbo and i would really like to put the 2.5 heads on. I think if i have read correctly that 2.5 heads will fit, but im just worried about all the small things that i might have to change. i would just like to have everything in front of me rather then tearing everything apart and having it sit in my garage for weeks.

This has been covered before. I'd suggest searching some more.

The biggest issues you'll run across are that the 2.5 n/a heads are not tapped/setup to supply coolant & oil to the turbo, or return the oil to the head.

In addition the intake manifold will have to swapped over.
