Hi all,

I have heard that there are ways to modify the standard GTR airbox's to get more air into them.

I want to keep the factory look, has anyone done something? Has it worked? how have you done it?

Thanks

D

Do you have the attachment that connects the box from the RHS into the guard?

If its the same as the 34 GTR, there will be a cover on the inner guard side of this attachment. You can take this cover off to increase air intake.

Power level is 422rwks, on 19psi.

Just changed to bigger twins and want to chase 450+ rwks

Why does that matter??? I just want to know how to modify the thing

So you're making 422RWkw with a completely stock airbox? - Good to know!

Yep removed that already, anything else I can do? :)

Hmm I might be able to cut out a much bigger hole and a custom larger pipe into the guard :)

I found that the stock airbox was becoming limiting around 500rwks so I need to custom make something however still need to retain the standard appearance :)

Whats your current power level and mod list?

It may matter to you that Piggaz car has made a genuine 470rwkw with a standard box and NO modifications. So he MAY have saved you some time and energy

The engine side of the gearbox you can modify that to accept a filter then modify the snorkle to feed air over it. It ain't a 5 minute mod though. I don't know the part number for the filter. Haven't gotten that far.

Also tickle the alloy pipes that bolt to the comp housings. I've sent you those pics before I think.

      Manual Shifter slightly bounces/moves/vibrates when accelerating/deaccelerating

      Congratulations on your find  Did you mean it has 6k miles or was that a typo? Firstly, keep in mind some movement of the shifter is normal...it is a long rod hanging out of a box bolted to the engine. Having said that there are 2 next places to look: 1. Transmission and engine mounts. If these are worn or broken the shifter will move around more. They are reasonably easy to source and replace on a hoist, and possible but uncomfortable to replace car stands 2. On the bottom of the shifter there is a nylon cup that sits over shifter's ball end. If this is worn or broken the shifter will move around more than it should (but will still shift OK). That is a cheap part and requires removal of centre console, rubber shifter hole covers and a circlip in the gearbox shifter hole to remove the shifter. Re maintenance, as with any new import you should change all the fluids including transmission when you get it; never trust the seller and previous owners to have done the right thing. I am pretty sure R34 GTT is the same as earlier big box transmissions, so use any good quality GL4 75w90 trans fluid if it is shifting well (if it is hard to shift due to synchro wear, redline shockproof lightweight will keep it alive a bit longer before rebuild is required)

      Misfire/stalling issues

      Well considering I have the exact same problem with that as the original one I don't think that the ignitor is the problem. I would imagine that this being such an uncommon problem the possibility of getting a new ignitor that is bad in the same way as the old one has to be very slim. I'll definitely pull everything apart this weekend and check the turbo out. Got quite a bit of things to check out Saturday like fuel pressure and the pcv so I'll report back once I do that.  Thanks everyone for all the replies this is all really helpful

      Rb's have issues with bottom end starvation, not head starvation. Which either way, you probably wouldn't ever see on a dyno. Strange... What's pump gas for you? Octane rating?
