Ok this one is for the really clued on, I've got a 89 r32 gtst 4door, engine mods are FMIC, full exhaust, Apexi power filter insert(yep running stock air box), & alloy rad. Now prob is, when car hits full boost, 9psi(lol), the rear window jet sprays the back window! So I was thinking maybe a vacuum hose somewhere is plumbed wrong. Not real sure any help would be appreciated. I know it's not a big prob, but is really annoying, & don't want to just disconnect it.

I'm not the really clued on but I'd look in 2 places for a start.

The windscreen wiper bottle has 2 motors. 1 for front and one for rear. See it is connected up correctly to the water lines feeding each front and back.

I'd also look at the boost solenoid on the firewall drivers side near the compliance plate to see if there is more than one hose

maybe a T piece or even set for an aftermarket boost gauge that has now been connected into the wiper system somehow.

thanks will do, it has a after market boost gauge on it, has a T piece, but didn't notice where it ran so will go and see where it goes.

the vacuum hose that was making the noise that was reconnected - maybe worth a double check to see where it is from and where it goes

post-132714-14225277336731_thumb.jpg this is the vacuum hose that was disconnected at one end. The end with the cable tie was off. And if you follow the hose you can see where it ends. The end that came off is connected to the stock oil/air seperator. As for the boost gauge, it's all how it's supposed to be.

      Rb25det timing belt position on cam gear

      By drifter17a · Posted

      I just changed the timing belt on my RB25DET NEO and wanted to get some opinions. I’ve been super cautious, did a lot of research, and took my time. I’ve driven the car, and it runs fine. After warming it up, I revved it to 8000 RPM a few times—no issues, everything held up.   After the drive, I heard a noise that I think is either the clutch or possibly a tight accessory belt. It’s not constant, just comes and goes.   I took the timing cover off to double-check everything:   Belt is on properly, Tensioner is tight, Did the 90-degree twist test—belt isn’t too tight or too loose.     What still worries me is that I noticed the belt seems to sit a little toward the front edge of the gears, especially on the idler pulley. It even looks like it’s slightly coming off the edge there. Is that normal?   My old belt (5 years old, ~3,000 miles) also showed a bit of wear on that same edge, so maybe it’s just how it sits? I’m probably overthinking this, but since it’s my first time doing this on a NEO and the engine is forged, I really don’t want to mess anything up.   Also, I’m thinking of swapping to a clear front timing cover with the glass window. Would you recommend NITO or HPI? HPI looks reputable and their covers have 2.5mm thickness, but not sure if there’s a real difference between the two.   Any advice or reassurance would be much appreciated!

      Powder coat on mating surface

      By GTSBoy · Posted

      40 grit sounds about right, to start. You make some decent cuts/damage in the coating with that, then rapdily scale up to maybe 80 and 120 for the bulk of the actual removal, then fine it off to 180 or 240 perhaps. No need to go any finer than that, and maybe no need to go even as fine as that. Wrap it on a big block and have at it. At least on the hub face.

      Hiya!

      Do the GKTech rear lower control arm mount relocation, and either alloy subframe inserts or very stiff subframe bushes. Traction is going to be at a premium!

      Hello,   My name if Frederick, i'm 30 years old and I live in Belgium, Europe! I used to have a Nissan 370z daily but since I got a company car I turned that into my seattime driftcar. About 3 years ago I also wanted something older with more feel, so I got an R32 GTST with an rb26 engine. I am now getting the rb built to have around 800hp and it's close to being finished. I'm very excited for how it will drive and how driveable it will be! Regards, Fred!

      ENR34 - Inner Tie Rod is unique part! Replacement?

      By AdiR34 · Posted

      Appreciate the insight! Talked to some local folks and they basically told me "it's not that deep." As long as the threading on the inside matches what's at the steering rack, everything else can be constructed-to-fit. There are full aftermarket kits I can use - probably better for my car overall since it's lowered.  Example: GKTech M14 Super Adjustable Inner Tie Rod Set - Nissan Skyline R32 R33 R33, 240SX, 300ZX, 350Z / Infiniti G35 M14I-TROD-2 gktM145-TROD gktM14I-TROD - Concept Z Performance (These can be packaged with their "high misalignment" tie rod ends).
