I wanted to get some opinions from those who had experience with these units.. basically i'm running a pair of newly rebuilt RR581's, on a fresh built R33 motor with all basic upgrades.. downpipe,injectors, fmic, filter, z32 mafs, tomei dumps, cams, and slightly higher compression, however not by much only by a point or so..

Since we only have 91 octane here car will be tuned to max on pump gas and leave room to turn up boost higher with race gas.. any ideas what I may expect?? ball park?

Many tks for comments in advance!!

btw, it will be tuned on power FC with datalogit..

tks Gents! Why do you say laggy? They seem like rather small twins.. slightly bigger than stock.. I'm sure it cant be laggier than a single set up?

91 will definitely be the biggest problem so we shall see what kind of numbers it turns up.. the set up is an S13 chassis with a freshly rebuilt rb25 trans..

      Rear Main Seal (RMS)

      6.3-8.3nm....pretty damn light those fine m6 threads in the aluminium retainer plate are very easy to strip

      What are the torque specs for those 6 bolts on the retainer plate and 4 oil pan bolts? I'm currently tackling this job during an auto to manual conversion... I thought this would a 5 minute job!

      Forged piston skirt coating or no coating?

      By Desean Strickland · Posted

      Tryna decide if I should get a skirt coating on my cp 2618 forged pistons that im about to order. Anyone have first hand experience with a forged RB with coated or non coated piston skirts? Is it worth it and does it make much difference? And for people who went with 2618 pistons with no skirt coating how long has your engine lasted? The engine is an rb25/30 and main concern is  that It will be a daily car and will probably see a fair bit of short distance driving, have been told by my machine shop and my tuner that generally a forged engine lasts around 40,000kms before needing a rebuild. Would a skirt coating make much of a difference? cheers

      Can anyone shed some insight on this Turbo?

      From now on read it as minus 5 and minus 7 instead of dash, and you're correct...

      R32 GTR fuel gauge not working despite fixing fuel level sender

      By XoRoKu · Posted

      Opened up the cluster to inspect the gauge itself for signs of damage and it looks good. Got curious since that needle doesn't go back to a "neutral" position by itself (it stays in the same position when ignition is off. so I manually moved it to 1/2. Connected it back, turned on the ignition and the needle started moving up! Not sure what's up with that but before that the needle was way down below empty like fully south west. There's always a chance that the needle moved slightly the first time I tried and I didn't notice because of how slowly it moves and how far it was from the markings. I don't know if the current needle position is accurate so I'll fill it up and see where that brings it. I guess I'll try to adjust it manually if it doesn't get to F. Looks like the needle position is relative and not absolute? Thanks all for your help and patience!
