Which 60-65mm throttle body (TB) for easy upgrade on CA18?

[Vetal]

Yes 4 port head. I wouldn't want to mess with ITBs, I think 65-70mm would give me enough flow even for some 600HP

what about p11 primera GT sr20de tb?

What about this, from Sunny GTI? Easy to fit (swap plate/TPS)?

Those who used SR20 throttle bodies, what do you do about TPS? Yesterday I compared both TPS's and I don't see how could I swap between them between CA18 and SR20 throttle bodies...
Here on the right SR20 TPS "drive":

I'm using RB20 throttle, it is bolt on to the CA18 intake plenum but up side down, the throttle cable mount need to be redo.

Got my hands on SR20 already, but don't understand what to do with TPS...

Just use the SR20 TPS, the plug will be different from CA,
just cut and connect 2 wire for MT CA, the power pin and the signal pin,
for the AT CA, you will also need the 3rd pin which is the kick down switch.

It doesn't have idle switch which, from what I read, is needed on CA

Oh...forgot that SR doesn't have idle switch,
so I think RB20 throttle is more easy to make it work on CA.

Yeah, but water lines upside down...

Anyone knows how to make SR20 TPS work?
