rb25's have circle exhaust ports and rb20's have oval shapped....i think

know a bloke with one has a 1.06 exhaust housing on an rb26 hits full boost at 5000rpm has nothing until then, but has 510 all wheel horsepower on 18psi

is it ok to just remove the rear regulator and put a fitting on it like a sard one and plumb it straight back to the fuel return line...wat is the purpose of the damper regulator?

i would like to know because the rb20 rail has a regulator at the end which is in the way of my new plenum, where as the gtr fuel rail doesnt have the end regulator it just runs straight back.

just wondering can a GTR fuel Rail bolt straight upto a rb20 plenum? does it line up the same as the rb20 fuel rail?

wanted Gtr fuel rail pm with your price.

does anybody know the base timing for a rb25det its just a stock motor?

TURBO IS SOLD.

FOr sale is my RB20/25 High Flowed Turbo with steel wheels, comes complete with brand new HKS actuator, turbo is in excellent condition, only used for 10,000k's, doesnt leak any oil, has only ever been run on 12psi and made 180rwkw on my rb20, could definatly make alot more power with more boost. Location: Brisbane Price: $1150 ONO

need a rb20det silver top head, complete from valves to cams..in queensland.

yeah i tensioned the bolts up in the exact order of the manual to exactly the right torque...and i checked the oil feed fo the bearings where it sat and they are all fine...i will get a picture tomorrow and post it up it just looks like a complete snap in half as if you broke it over your knee..and iut snapped right halfway down cylinder 5 actual so only 1 inlet valve was opening in cylinder 5 and none on cylinder 6...and now one of the bearings has the slightest mark in it from where it broke and wedged itself..it snapped one of the bolts that hold the cam caps down aswell.

they were installed correctly with the torque settings used out of the rb20det workshop manual..they were brand new and were in the car for about 6000k's...and no none of the caps were swapped around i had them layed out perfectly where they came from...my mechanic thinks someone had dropped them hard in transport which might have put a hairline crack through them that was not visible to the human eye

hey guys just wondering if anyone out there using tomei poncams in their rb20 have ever snapped one in half i was driving down the road and gave it a bit of squirt then it sounded like i lost a cylinder...so when i got home i checked for coilpacks and all the usual stuff (ignitors, sparkplugs) and then did a compression test...cylinder 6 read 0psi i took the rocker covers off and cranked the motor over and i noticed that the inlet cam was completely snapped in two pieces right where cylinder 6 valves start so the valves werent in operation....the motor is still in good nick nothing wrong with the valves nor the piston...but im just curious on how strong these poncams are, if a camshaft that is around an inch thick of solid steel can just cleanly snap in two it must have been a manufacturing defect or something. i dont know.

hey guys...my rb20 just blew up..and im considering doing this conversion as i have heard its a great upgrade....just one question though...i have a rb20det power fc...but if i do this conversion i want to run the rb26 head...will my power fc work with this head (i dont mind if i have to rewire a few things) i already have modded the wiring loom for stock gtr injectors. any help would be good cheers

hey bud they will definatly fit a r33 with standard ride height

hey im after a factory alloy R32 Gtr Bonnet must have no dents and can be any colour, prefer brisbane.
