Sorry to bring this up again guys, i sure theres a tread about his, but i can't find it unless its about the GTS-t . I know all the turbo version uses Premium Unleaded, but wat about the N/A model? I got the 1993 R33 GTS25 (Non-Turbo!) So wat fuel do u guys use and recommend? Without harming the oxy sensor.

Thanx in advance...

Thanks, so i'm assuming that when you guys said premium unleaded you mean ones like BP Ultimate, Shell Optimax, Caltex Vortex etc... Cause BP for instance, aren't there like the BP Ultimate with 98 RON and the Premium Unleaded with i think 95 RON?

Someone clear this up for me please

Thanx again.

ultimate is the stuff man, never heard of premium unleaded from BP, thats just the normal stuff. Ive got a user handbook which says anything over 95 however because they are run on 100 in japan its reccommended to use hihger octane fuel like shell, BP, which are 98 (from memory) caltex (97) and errm the others lol.

nah the handbook i got was an 8 page nuthing really, just had sum general things about the car, nuthin special really. I suggest u go to that website that skyla put on cos they are pretty cheap the workshop manuals, i would get one if i had the money to get it :D everything about the line would be simplified then at least!

Yea i won't spend $250 for the workshop manual but may be $50 just for the owners manual. Is that the one you got nismoman18?

And skyla for this one http://www.jpnz.co.nz/xcart/customer/produ...12&cat=8&page=3 how much is it in aus dollar plus postage and handling, do you know? It would be good if aust has got one here. :D

ight thanx guys...:burnout:

I think the exchange rate at the moment is about $1NZ = 0.87c AU so you would be looking $43.50 AU. Sorry don't have a clue on what postage would cost.

I do have a R33 owners hand book, but it's in Japanese. But it still comes in handy now and then.

Bp sell their "BP ultimate 98 octane" and a few BP places also sell "premium unleaded" which is 95 octane, instead of ultimate.

My old R33 GTS ran on regular unleaded, which is what was recommended in the Japanese Handbook. The handbook for my GT-V (RB25DE) recommends nothing but "Hi Oku", or premium unleaded.

Incidently, it's commonly believed that the Japanese use 100 octane (RON) fuel over here. So far, I have yet to find a gas station that listed the ratings of the various fuels available, so it's hard to say for sure exactly what octane Japanese pump gas really is!

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
