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.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
