always premium.

although this week i happened to get some AVGAS for free... about 25l. lol.

so that went in my tank which mixed with 10litres of premium. better stuff :thumbsup:

I run AvGas in my racecar. 5 reasons why what you've done is a bad idea:

1) AvGas is lower specific energy. meaning you risk running lean without a re-tune to suit.

2) its leaded and illegal for road use.

3) its leaded and will kill your cat converter.

4) AvGas has a short shelf life and degrades quickly = lower octane.

5) AvGas is very hydroscopic (absorbs moisture) and can cause problems in your fuel system if its not straight out of a new sealed container.

good thing you only got 25L, so at least it won't be in there for long. but I'd be topping up that tank with 98 or higher unleaded to dilute it as much as possible and avoid any nasty side effects.

Seriously, how much do you really save filling up with cheaper fuel.... a few dollars. Then take into account less k's from the tank of cheaper fuel..... if you need that $5 you saved that badly, maybe you should buy another car.

That's what I was trying to say. :nyaanyaa: Buying another car because you need that $5 is just stupid though, but I know what you're getting at. :)

      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?
