4age 20v/16v manifold compatability

I am running a RWD 4age 16v on 40 Dellorto's, Im thinking of upgrading to fuel injection, I was offered a set of 20v ITBs, not quite sure yet, Obviously a ECU would be needed, the question I cant find the answer to is..... will the 20 injection bolt straight on, I have asked 2 people will it bolt on?, one says nope, one says yes, whats the real answer?





Something different, Very different..............

I belive the head has a different bolt pattern for both exhaust and inlet.

4AGE 20V ITB

The intake bolt pattern and port spacing is slightly different between the 4AGE 16V and 20V. Search Square Engineering or T3 for an adapter to fit the 20V ITB's. They may have a distrbutor in England or you may have to import it. DaveW

I thought that the 16v came in small port & large port inlets too?

You do get large and small port heads but i have a feeling they have the same pattern as they are both 16v. The 20v is different.
