Has anyone tried the rb26 greddy pulleys on an rb25?

As far as I can see online the alternator and water pump should fit, not sure about power steering though. Google won't tell me the sizes of the pulleys either so I'm unsure.

Just to add to this, the RB25 S1/S2 power steering pulley is 3 rib where as the RB20, RB26 & Neo have a 4 rib. This link mentions it and and the offset GTSBoy mentionned.

I have used the ebay/greddy knock off kit. Don't bother.

Bought the nz performance water pulley - good item, but hey only bought it cos i like wasting money on car parts. Dont expect anthing crazy like "noticeable performance gain", come on :p.

use spacers to move the pulleys? 

FYP 😜 I want to see the carnage

The pulleys are a waste if just wanting fancy blue ones. Remove your current ones, clean them and get them anodized.
Only time to change is when required to under drive power steering & alternator if spending alot of time in high rpm (ie...on race track)

In the link you shared it says that the alternator and water pump pulley offsets, groove count and diameter are all the same across RBs. If that's the case I could use those 2 pulleys and not worry about the PS pulley,  is that correct or am I completely missing something?

Cheers mate,  I don't expect anything noticeable, maybe 0.1% but it looks better and I'm changing a few things anyways so I can make it look a bit ricier in the process.

Lol I'd prefer to keep the carnage to shredding a set off on a "private road"

      Slight brake pedal stutter after new pads

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
