Hi,

I have a clunking whining noise from my r33 when at a low rev sometimes and also hops and feels like traction control is on when it is about 5000rpms?

Any awnsers would help?

Thanks Alex

Yeah it's shuddering,

It starts shuddering when it's at about 5000rpm and doesn't wanna go any further, it's feeling like the car is redlining and the whole car is shuddering.

It's not a build up because it's smooth Intil it hits the 5000rpm.

It's sounding like traction control is on when you lose control in the wet and it's that jumpy feeling.

It's causing the back wheels to rumble real bad.

It doesn't matter what gear I'm in the engine runs out of rev.

That 'shuddering' at 5000 RPM is probably the car mis-firing. Mine did the same thing when I removed the boost restrictor. So try new sparkplugs first and if that doesn't do it then maybe coilpacks?

The car has been sitting a while so I'll change plugs, get coilpacks tested, change fuel filter, bottle of injector fluid and see how it goes.

I'll try that tonight.

are the engine mounts good and is the exhaust supported properly, the engine moves when your under that much load and also when your just driving from low speed, if your mounts or your exhaust are not solid then it might feel like a shuddering or like its hitting a wall. :whistling:

      You could try some less aggressive pads on the rear. I found (a long time ago when all my brakes were stock 32) that using the same (Bendix Ultimate) pads at both ends made the rear bias excessive. I strongly suspect that the stock Nissan pads probably use a different material, but aftermarket pads will usually be the same material regardless of what pad they are put onto. That bias situation did get better when I put R33 calipers on the front AND used the same pads - just transferred them from old to new calipers. So you should feel the difference with the change you're making. But certainly do not forget the option to change the rear pads down a grade or two.

      Ha ha, sorry dose, I wasn't meaning to argue the point on "it'll do f**k all". I was only shining a bit of a light in the flawed logic you used with it mate.   I 100% agree that there is zero point changing stock manifold with a stock turbo, unless the manifold is f**ked. And only reason I'd ponder aftermarket manifold on a stock turbo would be that I'm too scared too look at the potential ludicrous prices people are asking for a stock manifold! Ha ha ha

      Can someone tell me what this part is for? Someone duct taped it.

      Your response is extremely similar to what someone on the Haltech tuning tips Facebook page answered me. I take it you're also on there haha. Dyno is booked for June 27th and that's exactly what I'll be doing. I also realized I never setup a pulse width adder table so I went and did that last night. Made a fair bit of fueling difference in low load areas.  I sorted out my power steering belt woes. It was an alignment issue and it has now survived multiple instances of abuse that would have killed it prior. I also changed my fuel pump hose. The hose I replaced looks nothing like the legit gates hose I received. Real hose is actually 5/16" and is labelled properly. Amazon refunded me but has been giving me grief about my nasty review I'm trying to leave... I keep having to modify it for acceptance. I want to make sure the point gets across to others.  Last issue I want to deal with soon is the slight vibration I get in my steering wheel with my GKTech Spacers in front. My annoyance has grown and I'm at a point where I want it resolved. I've tried everything I can come up with like clean spacers thoroughly, tighten in star pattern, retorque, have wheels rebalanced 4-5x with a variety of machines (2x with a Hunter elite). I've also taken the spacers off and remounted multiple times just in case.  I'm starting to think my GKtech spacers are at fault. I'll pop a wheel off and toss a dial indicator on tomorrow to verify runout and parallelism.
