Throttle bodies

[jogi730]

Has anyone ever done a throttle body per cylinder conversion or know of one?
If so what throttle bodies were used?
Personally know of one where a 4 cylinder using GSXR 1100 throttle bodies on Megasquirt system.

Don't know, but I heard some one telling that do not worth it on turbo cars ...

We did 2 versions of the same turbo engine installation, one conventional with 2 correctly sized throttle bodies, and one with Port Throttles, just to see what the effect was.

End result was, lots more complication for no real gain. If the conventional throttles are sized correctly, there is no benefit to port throttles on a Turbo application.
In a N/A aplication then the Port throttles are much better for driveability.

If you still want to try it, BMW M3 has a nice set up or Jenvey make some very good individual throttles.
For Bike throttles, BMW Boxer twins are a decent size

Nissan Pulsar/Sunny turbo used TB's for there turbo lump. So did the URq rally cars IIRC??

The Nissan throttle bodies are a weird setup apparently. THey double up so two butterflies contained in one (or something like that).
