y are u runnin the sx loom
how do u expect to run a 20v on a 4age ecu
dsome poeple are so bloody dodgey
anyway check if the injectors are pulsing
if they are then the ctank sensor is ok
is the ignitor earthed
but if u r tryin to run the 20v on the original 4age wiring and ecu then yr just wasting yr time
it might eventually work but it will be a waste of time
what bout the vvt whats goin to control it

my thought's exactly! Anyway, the 16V triggers have only four teeth with one trigger tooth, and the 20V has 24 teeth and one trigger tooth, So ask yourselves how is the ECU able to tell the difference? My gut feeling here is the output is showning 7 times more pulses and is confusing the ECU and it's just going "Yeah right! WTF"... Just run the 20V ECU!

The smallports use a 24/1 tooth setup as well, my thoughts are while u may be able to get the engine to run, ur spark/fuel maps will be way up the shit (not tooo bad i would think) and you will have to find another way to switch the vvt on and off
Sounds like a pointless excercise, for best results go find the right ECU

I was think last night about this and there is a way around the problem, we use a 20V setup on our 7afe, but we use an autronic, so this doesn't car what we use. But my point is that if you use the 4AFE dizzy it has a 4/1 setup same as the 16V and does if the hole/cam of the 20V, the only difference is that the location of the tigger tooth will have to be the same as the 20V, which mean you'll have to move the dizzy to match this and then lock it in. This may then work... Well B/top? ok standard, but not good for working them stupid. You can adapt all the good stuff like throttle bodies, cams, flywheel to a S/top, which is what we are in the process of doing.

No, we just get Better results and reliablity from the S/top. The combo we use are B/top throttles+manifold, b/top flywheel and yager cams (260 deg 8.8 mm lift)and S/top head and rods, Forged Pistons, 13:1 comp, motec,etc Good for 150fwhp. B/top rods couldn't handled constant redlining, and the rules for this engine state factory rods. The watered down verison uses similar gear but has standard 20V pistons and only 11:1 comp through shaving, b/top cams in which only the intake has slightly higher lift (8.2mm vs S/top 7.9mm), exhaust cams are are identical 250deg,120fwhp; both use customed made and designed headers. Ported, shaved b/top, same pipes made 120fwhp, So why pay the extra $$$?? Most people Buy a B/top to say "hey, I've got a B/top!" That nice's, I've had one for nearly six years and costed half the price they are today! And I ended up converting it from a 6-spd to and auto for the missus! That was a struggle.... The problem with the B/top is the rods and "squish" areas in the head, Shaving the crap out of a S/top head gives much more comp if and when you do the same amount to a B/top. Also the S/top has a lot more meat to play around with in the ports, So a really good porter are able to get better flow rates from the S/top head, seen many times.
