The issue might be the angle or exact positioning of the bracket that mounts to the rear of the gearbox. My CES pipe has a different but relevant issue that comes from how it lines up with that mounting point. Basically being slightly off there gets carried down the line.

I suspect you will be able to make up an adapter out of a small piece of aluminium that will work to bring the whole thing own a little. There is a little flex in the whole thing so dont worry if you have to pull it down to get it to mount differently. For example, there are two holes so instead of lining up both you could line up the bottom gearbox mount hole with the top exhaust bracket hole and try that for starters.

thanks abo...... i fixed it today, it was hitting on the bracket bolted to the floor pan to stop the tailshaft hitting the ground in the event of failure, so i took the bracket off and elongated the holes and bolted it back up so it sits slightly higher now..... no noises at all anymore yay!!!

30 mins i find that hard to beleive....... anyways i got under the car this arvo and its not hitting up the front it is further down near the tailshaft centre bearing, its hitting the bracket that sits on top of the exhaust and under the tailshaft centre bearing. maybe pics would explain better. Any ideas on a fix????

No joke Ben :D Grey Imports fitted it up for me.

You do need to be weary when fitting any front pipe that when you are removing sections of the exhaust its possible to shift the rest of the system in the process which can result in the problems you have had.

As others pointed out its usually a case of trial and error and hanger/mount adjustment where applicable to get it spot on :D

hey blitz just out of curiosity what differences did u notice after having yours fitted???

Well, I had a hole in my original factory front pipe which sounded terrible, but once we fitted the new JJR pipe up the car generally sounds a whole lot smoother, with a nicer exhaust note and it seems to drive nicer also.

      Dumb question, but why would it matter if the wheel came off a car with hicas or not?

      MAJOR FUEL ISSUES 25det neo r32

      By 25debt · Posted

      Hey to anyone that reads this, long time lurker first time posting, sorry if it’s been answered before but I’ve been looking for nearly a year now for answers. ive got a 25det neo in an r32 that works awesome when it works (made 500whp on 21psi) but works 45% of the time, 1st issue there’s a harness that runs under the passengers side front fender that my tire keeps rubbing through and one wire seems to power the fuel pump even though I’ve done the relay “mod” some people like to call it, and when it does rub through it kills the car, yes next time I’m with the car I want to take the fender off and try tuck the harness well out of the way but I’d also like to try and by pass this mysterious wire as well lol, also wouldn’t mind getting power from the alternator as I’ve read it supplies the pump with 13v ? But no idea where to run the power wire too. 2nd issue, when replacing my fuel pump and fuel hanger I managed to break the factory fuel level sender leaving me with no fuel gauge, I’d like to buy the fpg fuel level sender for r32/s13 but the plug it comes with confuses me, I’ve got a detschwerks x1 fuel hanger which has light + pump - level + pump + and a ground, I’m no auto sparky but I’m wondering if I can cut the plug off the fuel level sender and wire the negative to the pump negative and wire the positive to the level positive to get a fuel gauge back ?🥴 3rd and final issue, the reason I want a fuel gauge is because whenever it’s below half a tank, it fuel starves like crazy and runs like a bag of shit even without doing a pull or sloshing the fuel round in the tank, I’d also like to fix this but have no idea what’s causing it, I’ve got a dw420 and a dead head fuel setup meaning the fuel is regulated before it gets to the engine, my only theory is that the return line is to close to the pickup on the pump and when it’s at half a tank the return line is causing the pump to cavitate enough to cause fuel pressure issues, that or the pump isn’t low enough in the tank which I would find strange considering I can’t find a single thing online about it, also if ya wondering how I figured out it happens at half a tank without a fuel gauge, I waited until it started happening and went and filled up and the car took exactly 30 litres every time I tested it, if ya managed to read through this mess I appreciate that and any recommendations , cheers

      ChatGPT is trash and lies about things I would not expect it to lie about considering many things it's wrong about are very easily verified with google. The S3 R33 GTR shares its steering wheel with R33 GTSTs of the same production year. Part number is 48430-26U17. I'm guessing you have to get it from a car that came with HICAS though, the ER33 is 48430-26U18, but the HR33 diagrams note that part number is still leather vs 48430-26U13 which is not leather-wrapped. They all use the same airbags, so if you need another one you can get it off basically any same year R33 or Stagea.

      Never ending fuel pump drama

      I'm going to run hard lines front to back in the future. That should help dissipate a bit more heat. If not, a fuel cooler might be next

      rb25 Degreeing cams with hydraulic lifters?

      By MBS206 · Posted

      No. The mark is with respect to the cam rotation. None of those things have altered it. When stationary, the cam position stays in sync with the crank position. It doesn't matter if you moved the head 4 feet up. Hence, that mark needs to stay exactly where it is.
