Hi guys
I would like to know if anyone on the forum has had any success in installing the Individual Throttle Bodies from the 20 valve 4A-GE onto the Big Port, TVIS, Red and Black top 16V?
I've read that you have to pick up the idle air somewhere in the system,and supply if aft of the fully closed butterflies?
Also, where will you sense vacuum for the MAP sensor?
Any advice appreciated!
Cheers!

to get the setup working you need to ditch any factory computer so you need an aftermarket realistically.
Ignor trying to get the idle air working aft of the throttles
you can just set the throttles to be open a little just like a conventional throttle,
and because you are running an aftermarket computer you dont need a MAP sensor either, just tune it to the TPS.
It keeps it nice and simple.

if you get a wolfV4 ecu it will allow you to run in MAP over a set rpm ( user defined ) and under that rpm it switches back to TPS, makes for a nice smooth idle. Wolf has some really nice features for that sort of tunning.

With the Silvertop Quads, they already have a set of nipples preinstalled into the bottom of the throttle bodies in order to get brake vacuum. And just use the TPS for fueling.
