Hey i was wondering what machining needs to be done to an RB25DET to fit GTR crank and rods? Is it a big job? Is it worth the hassle or would it be better to stick with standard crank, building motor to push out 400rwhp so would it be a benifit for my power level target?

it would be a waste one would think to fit these to make such a small hp figure i reakon save for stronger pistons,linished rb26 rods and a set of cams cam gears etc this car would be a totally internally reliabe 400rwhp streeter SK your needed:) someone correct me if im wrong.

Hi all

Im new to this site and i was wondering what everyone would suggest, for me to be able to get around 300rwk from my gtst without changing the internals.

Current mods are full 3in exhaust, pod filter, adjustable tein suspension. Everything else is still stock as ive only had the car 3months. any sugestions would be appreciated thanx. These cars are the best :headspin:

so gtr rods will fit on the gtst crank? Sorry for the questions, as dumb as they may sound i honestly have no experience in this field and want to know alot b4 i build my motor, i dont want to build it and then find out that i could have used something else etc to get a better result.. thanx

Yep, RB26 rods are a cheap upgrade in an RB25 - rod length, journal size and gudgeon pin size are all the same. Rod width is a bit beefier, expecially around the big end journal.

300rwkw is pretty easy to get on a standard bottom end, there are a ton of posts on the forums of people who have done it.

No V.V.T. on the intake so you'll need to swap over to either RB26 cam gears or adjustables. Are you talking standard cams? If they are aftermarket you need to be careful of lift as they are made for solid followers, not hydraulic as the RB25s are... unless you convert them with a Tomei kit. Or RB26 valvetrain. Or make your own out of Coke cans. Or ask Alby Mangles for another way.

LOL (clown) :D

Im talking Standard cams, with adjustable gear.. I heard that this mode is done on the RB20's.. Not sure it would benifit a rb25

    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
    • Perhaps the answer is... more jacks!* *proper jacks must be used.  
    • I NEVER think about using a scissor jack unless there is absolutely no other alternative. f**king things are dangerous, annoying and stupid.
