with something like this, i would think it has more to do with the ISCV (idle speed control valve/motor)..... i had a similar issue with a 20V conversion i recently completed, whereby the engine would idle nicely when warming up - but once at operating temps the engine would run out of air from the idle being too low.
How the ISCV works is that when the engine is cold, it is fully open (or near fully open) allowing the engine to idle a little higher than normal.... and as the engine warms up the ECU (engine control unit - computer) starts to close up the ISCV to bring the idle down to the 800-900rpm it should be at.
With the conversion i just did (same thing - silvertop 20valve into AE92 SX seca), we tried cleaning out the ISCV in case it was getting "sticky" from oil residue etc... but it still seemed to be a bitch.
The solution was.... unplug the ISCV. Yes the engine will idle a little higher when warm... but at least it doesnt die!
