Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

how much is it for a 4wd sump adaptor?? how much do the prices vary? i know RIPS in NZ make em and one guy on here (forgot his nickname) and sydneykid said his fabricator makes them.

i want one that fits first time with no mods at all.

also could i use my rb26 power fc djetro on a rb26 head/rb30 bottom end? how do i go with the difference in knock sensors on the rb30 bottom end? do the rb30s use 1 or 2 knock sensors?

cheers

RB30 uses ONE knock sensor in the middle. BUT they have the provisions for the 2 knock sensor in the standard position from the rb25/26 so they bolt straight in.

question for Sky30 . or anyone who knows

what rear housing are you using on the GT3540 ??

and have you got a newer dyno sheet than the one you posted in the RB30 results thread?

Im using some kind of .82 truck housing with internal gate machined to suit GT35/40.

No further results to that dyno, that was running stock plenum and stock exhaust manifold.

Thats is a good result!!!

Wondering if anyone has solved the bonnet clearance issue??? I have now been driving around with my bonnet open LOL and i dont want the cops to pull me over...

is it hitting the support bracing of the bonnet or the actual bonnet skin?

I have cut the support braces off, its touching on the bonnet itself where the corner of the inlet manifold is... i really dont like driving around with my bonnet half open LOL

Fatz silvia special?

Take it to a crash shop and ask if they can nicely put a controlled dent in it or something.. Looks like you may have to go some sort of bonnet scoop, shell out for an aftermarket plenum or thought about grinding the plenum yet?

Have you tried to space the rear of the bonnet up using a spacer between the bonnet and hinge?

Or space the engine crossmember down a bit using some big washers?

Yer i tried spacing up the rear of the bonnet and didnt work, im not going to play with the cross member for obvious reasons, looks like its going to have to be a bonnet scoop...

      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.
