someone made experience with adaption of a 3.2 l engine (C32B) into 3.0 l (C30B) engine compartment. (throttle and ECU)
Seems that there are many things different.

engine 3.2 for 3.0

If you are placing the 3.2L into a 3.0L car, you can use your existing wire harness, throttle body, intake manifold. Nothing is different as far as performance goes, just emissions and throttle by wire on the throttle body. Depending on the year, the 3.2L heads may have air injection ports on the exhaust runners, which you can just weld shut.
Good luck with the swap!

I'm asking me if there is no other change to the Spec R 2002 engine.
Do you think that the complete intake is the same and not modified?
A small example.
I did installation of 3.2 l NSX-R valve covers to 3.0 engine.
The hoses have different sizes in diameter front and rear comparing to the 3.0l system.
The PCV valve at 3.0 l engine is installed at the front valve cover, at the 3.2 l engine its at the rear valve cover.
Now I have 2 PCV valves installed at the intake, because I dont wanna change the front system.
The rear NSX-R valve cover has a grommet, so it was easy to install another PCV valve.
Any reasons not to do this ?

hi Detlef --
I don't fully understand your question, but I do not believe the intake system has been changed other than different emissions plumbing.
In regards to the front valve covers, the later models have a fitting in the place of the grommet and valve on the earlier years. You could routing this to a vented catch can, or duct it into your intake track with an inline valve.
