Well the AAC/idle control valve controls engine speed (by a an amount) with a PWM modulated inlet leak.

That small amount of adjustment is required to give you a stable idle even though there is load appearing and dissapearing.

A/C, h.beams, stereo etc etc, as well as catching the motors decel after depressing the clutch.

AFAIC, if you don't use one, your idle will fluctuate with engine load at idle. That idle RPM in question will need to be set quiet high too, to prevent stalling when above said "motor decel, clutch press" occurs.

Interestingly, i guess a race car wouldn't need one. Could you let us know, why your thinking you don't need one?

My enginneer don't wants to leave it... as the A/C... as my ABS :down::(:ermm:

And for steering he will use electric pump not hydraulic (from a toyota car).

Also he don't wants to put the 044 pumps into the boot...

No idle.. no a/c.. no abs.. and two 044 in my ears!! All theese for every day car?? ;):( :(

I want my car for drag races but also for everyday use... so I think that I need the AAC! But how to obligate him to do it... he wants to make my car for race use only. :wave:

Will be an interesting daily street car with 600hp, no anti lock, no air con, and two 044's mounted in the engine bay :)

Its your car man, your mechanic should be making your dreams and wishs come true, not to have you fund his garage's demo car :D

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.

      A bit late but A disk S13P fit over stock R32 GTR brakes, usually A disk front, O disk rear works.

      Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.

      Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
