Ok, so me and my brother built a rb25 180sx, we got the front facing plenum and the larger throttle body, its been a few months now without driving the car because their are MANY problems with it and i just realised now we got the series 1 TPS sensor because the throttle body only took the s1 TPS, so im just wondering which wires go where, on the s2 engine loom their is yellow/black...red/blue......blue/black and on the TPS sensor their is blue, white and pink? so any guide to that will help, iv'e looked everywhere and cant find anything on s1 tps -> s2 wiring.

another thing is this: i grabbed a multimeter and measured the volts the wiring is putting off

their should be

yellow/black -> 5volt

blue/black -> ground

red/blue -> TPS signal, BUT im reading like 2.5volts from this? with nothing connected, so its like the ECU is SENDING this wire a voltage? wat the boo!

help would definitely move this purposely built drifter into actually drifting, we finished it last year august, havnt even got a chance to run the engine in yet :(

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?

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

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      I would just put EBC back on the "I would not use their stuff" pile and move on.
