Bit if an update thanks to
just ace
My car Is back and running :) thank you so much for that fuel rail.

Not sure what ill do with mine either plug the hole and send the jap rail back to ace or leave it as a spare

Got the genuine o rings from toyota bought the last 8 they had on the shelf for spares :p

And installed a fire exstinguisher behind the passenger seat mounting it off an existing hole.

In the process of having a spacer for the Acis system made up by a machine shop
30mm from other should be good for 25bhp of torque.

Yeah, that's my plan to
Ill have it dynod before and after and update you guys it's popular with the supra guys so why not with us few jap guys have done it and from a stock gen 3 have gotten 132rwkw with that and a beams tb?

Thanks again ace

Yeah just saw that actually on my manifold,
How silly of me

Damn those 3rd gens :p

But here is the link could be fake could not be
But does make you think.

Also ace how does the Acis work on a gen 2 what does it actually achieve?

No, I think you've got it back to front.
I think ACIS works as described below, but anyone can feel free to correct me.
 
With the gen2  3sge with the motor running, below 5000 rpm the ACIS valves are closed, making the intake runners operate at full length (from the valves out to the throttle body -  long runner -  max torque).
A bit above 5k rpm the ECU starts to open the valves, effectively making the runners operate at half length (the lower half) for max power at high revs.  Something called Helmholtz effect and I  can assure you that ACIS definitely works.
 
Shortly after I bought my car I discovered that the ACIS valves were seized up. Water had got past the metal gasket into the middle hollow inside the casting and badly rusting the shaft. (keep this in mind if washing down the motor after degreasing)
It was impossible to free it up and I had to replace the whole ACIS assembly. After that it sure made a hell of a difference at high revs, and I could really feel the rush just over 5k.
 
To test that the shaft is free you need to carefully reach under the operating lever and check that it moves freely, but the service manual gives a full procedure for testing ACIS operation.

Ahh I see
So wouldn't there be some trick to keeping the valves opened from idle all the way to 7200? Or is that a silly question

So the spacer wouldn't work at all on a gen 2 right

Yeah that would be true it would be worth testing tho just to actually see what would happen. On both the 2 and 3

Anyone here played with keeping the Acis engaged from idle? If so decent gains? Or would it not be worth messing with it I have 2 Acis assembly's
Worth doing red targa or not ?

 A bad idea to totally disengage the ACIS (valves open) 'cos you would loose all your bottom end torque.
 
Before I fixed my ACIS the valves were stuck in the closed position so while my car was fine at lower revs, I was loosing a lot of  power at high revs.
Toyota designed it to work the way it does for a very good reason.
 
As for the riser/spacers, I have no idea of their value.
I have read several posts on various forums about them, but have never found anything conclusive.
