3lit3 32, why do u say not to run 0.8 gapped plugs if your running under 12psi ?

Because the specified gap for an R32 is 1.1mm. The whole idea is to create the most gap possible for the spark to jump efficiently. If you make the gap smaller than necessary, it will decrease performance.

The only reason why you should regap your plugs to less than 1.0mm is because you have a poor ignition system or the boost levels are higher which can 'blow out' the spark, therefore you need to close the gap to make it easier for the plug to spark.

General rule.....The bigger the SPARK gap, the better the burn...as long as it can contain and maintain that spark.

    • Hey, yeah I really like the color. Only paint I'd rather have is KN6, but those are expensive. Right now I'm trying to get the car to the point where I can get it tuned to 370hp so the whole setup can be driven legally, and pass the next inspection that is already due anyway. Beyond that lots of rust fixing I'm afraid, winter project is most likely going to be a front end teardown and fixing the strut tower rust. I know these can be driven daily but I don't think I will do so anytime soon. Will post a build thread soon with a list of issues and futute plans.   Cheers
    • Wanted to reply to this topic. I'm in the somewhat same boat with our Stagea. I'm trying to install a different rear diff. The Stagea/Skyline uses mounts on top of the rear diff for the ATTESA pump. Any way you can relocate the pump? I did find this kit https://theskylineshed.com/products/nissan-oem-attesa-mounting-kit-to-suit-r32-r33-r34
    • So here's the deal, my wife picked up an S2 AWD Stagea. Super cool, clean car. Looks like the owner in Japan went track spec as it's got some heavy modifications including Exedy twin disk, tension rods, coilovers, GTR brakes, oil cooler & a Nismo 2 way rear diff. Now, cool mods for sure. But, she is just using this as a casual daily driver. The 2 way rear is AGGRESSIVE. It also has solid subframe bushings & poly diff bushings. So that doesn't help either. So far I've tried changing the diff fluid to the correct fluid. Even tried a little friction modifier. No help. This thing clunks, skips the tires & has some slight whine/NVH when driving. Might sound like I'm being picky, but just trying to find a better solution. Here in the states, it's impossible to find a Stagea rear diff. No luck. I do have a 300zx non-turbo diff. Same ratio, 5 bolt axles. On the Stagea, you need both front & rear diff ratios to match. This car is a 4.083. I'd like to just swap a normal rear diff into this thing. Nothing fancy. Even open diff is fine. She's not tracking the car LOL The difference is that the ATTESA pump mounts to the top of the rear diff. There are 3 total mounting points for the pump on top of the diff. With all this being said, what would be the best way to go about this? I could remove the Stagea diff & see if I could get somebody to possibly weld the 3 tabs/mounting points onto the 300zx diff so we could mount the pump on the 300zx diff. I could swap the internals from the 300zx into the Stagea diff but this is not in my comfort zone. Is it possible to mount the ATTESA pump to the underside of the car? Sorry for the paragraph. Just trying to figure out how to go about this. Any help is much appreciated!
