996 Inlet Manifolds onto 986 3.2S


Recommended Posts

Hi

I'm looking at upgrading the throttle body on my 986 to a 996 body and 'T' piece.

I do however also have the chance of a complete 996 inlet manifold set up for a good price.

I'm aware of the issues of height etc and can cope with that without an issue.

Has anybody done this swap before and is it worthwhile?

Thanks!

Decided I'm going to do this anyway.

The 996 head fitment is the same, I'm using the same injector rails, etc and it's all been done before as part of a 3.4 install, so it should be do-able.

I'm going to do the 987 airbox whilst I'm in there (don't like cone filters)

I'll update on progress.

:help:

Looked at this is in a lot more detail.

The 986 plastic inlet manifolds have the mounts for the fuel injectors built into the bottom, whilst the 996 has a seperate alloy mounting plate below this into and onto which the injectors and fuel rail go.

This accounts for the extra installed height of the 996 inlets.

I don't want to drop the 3.2 (as it's tight enough with the aftermarket exhaust manifolds and exhaust that I have) so I'm looking at the 987 3.2 Boxster manirfolds instead.

I'll keep you updated.
