Hey Guys, Just thought I'd make a new thread for my GTS Build instead of flooding the other one. Here is the before shot One ugly, poorly maintained, unloved skyline. Set me back $3500. It's a

Hey yeah, I got all my bits OK :) A bit delayed because of bushfires, but they're all good thanks!

RB25 to go in the 33 is good to go now, putting that in on Monday.

RB25\30, progress is good, gotta save up for the machine shop work, then just re assemble it with some new bearings and new rings.

RB30e got yanked out Monday night, it got dark before I could rip the sump off and change the oil pump gasket and sump gasket. I might do that on Thursday afternoon.

Mega Super ultra powerful monster RB25 is still in the research and development phase at the moment, but I'm thinking. JE pistons with ceramic tops and teflon skirts, Nitto rods, balanced crank, nitto collar, ACL bearings, 12mm head studs, Bore and Deck block to suit, Grout filled block, all them oil control mods, Aiming for around 9.8:1 Static CR, still not decided on that really, NEO head some crazy cams and springs, yet to be decided. Not sure what turbo either, Looking for around 450kw though running on E85

I'm really undecided about the whole mega RB25, Lots of people say different things about what's needed for big power, like RIPS motors are like, near stock and good for like 500hp, and their built ones are insanely powerful. Put you look at everyone in the 400kw club here on SAU and they've got lots of mods.

First TSS round is in Mid March, I might go out to a drift practice day to shake the car down though, or maybe sprints, depends on how I go for time and what's on when I suppose.

In a RWD platform you'd be crazy not to put a rb30 in. Extra torque for no extra cost in the build.

Just keep in mind that RIPS build and TUNE the motors that produce massive power. Although stock can produce great numbers, it's usually the oil issues that kill them.

Id only use a neo head if you were retaining VCT. Even then the available upgrade parts aren't as good and a 26 head would be easier.

RB26 doesn't have vct, it also means he'd have to bin the exhaust manifold as well as the intake, neo and 26 have solids but the neo has larger ports standard, neo head studs are the same size as a 30 bottom (RB26 are larger), you can get neo heads cheaper, easier and usually in better condition.

Its a pretty obvious choice, the only thing it doesn't get you is "RB26/30" as its name, which loses value regardless of performance :P.

Oh, it doesn't? Thanks for clearing that up. Mine does.

His intake won't fit either way. Head stud size doesn't matter.

Ports aren't bigger, they are shaped differently to previous 25's.

bigger is not always better when it comes to these heads.

The solid lifters are also not the same setup as rb26, with a shim on top of bucket.

He was talking about modifying cams etc. so the head wouldn't be taken off a wrecker motor and put on without first being checked. Then start getting upgrade parts for them....

Any RB head can run VCT, but 20's and 26's need the head modified to make it work.

Janges is right, bigger is not always better on the intake size. The correct size is always better.

Any reason you want to run a solid head? Brad has been reliably running 1000hp on a hydro head.

Is it still a hydro head though?

Neo heads will spit shims in high rpm and kw applications.

Yeah I've been lead to believe that brads new motor has a neo head. And shimless buckets.

There is no doubt a 26 can have vct, but I'm not interested in doing the required modifications when just slapping on a neo head is a Shit tonne easier. Also neo heads have a smaller combustion chamber which will give me my desired compression ratio with my current pistons.

Plus they're cheaper.

standard maybe, you were talking about cams and all sorts before though on a super build.

      RB20DE NEO smallbox clutch.

      By Duncan · Posted

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      By MBS206 · Posted

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
