Hey guys,

Pretty new to the scene and very overprotective of my car hehe just need some help to calm my paranoid mind about my car...

I got 92 R32 GTR and i get this loud mechanical sound upon acceleration at low rpm which almost sounds like its coming from the middle of the car. Usually happens when im 2nd gear and going over a speed bump then accelerate once i've gone over it, as well as driving around a car park or at low speeds in street the noise comes on accelration and then after about 2k rpm the sound just dissappears. Took it to a mechanic and they said everthing is fine and its just a common sound from the gearbox and its normal. Still i find the noise loud and annoying and was wondering if it could be something else such as cv joint or diff. Was wondering if anyone else has had the same problem?

Also had a new Bosch 044intank installed and the car doesnt wanna start as nicely as it did before the swap (spark plugs? battery?)any ideas on this would be a big help

Many thanks

R32s are awesome, of course you are protective ^_^.

Sounds like the transfer case, may need some more fluid. Get your mechanic to check it out (common problem in R32 GT-Rs I believe). When it gets very low it will make a sloshing sound so I don't think yours is serious if much more than normal :) so don't stress. The other possibility is the clutch engagement but without being more specific on the sound I would be inclined to think the first is what you are hearing.

As opposed to Walbro, Nismo, stock fuel pumps the 044 doesn't keep fuel pressure when car is switched off (I forget the exact reason). With that pump all you need to do is let the fuel line prime for 1-2 seconds before you crank the engine. You'll learn to hear the sound when the fuel reaches the fuel rail.

also in regards to the sound possibly being a clutch issue, i have recently installed a 4000 pound heavy duty single plate clutch. to be honest the sound is a bit hard to describe but i would definitely say its a rough mechanical turning sound almost shuddering. dont know if it will help, but yea

      RB26DETT Sketchy boost mod?

      Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
