Hi guys,

RB26, JB clutch and stock flywheel

- Car has firm (but not overly hard) suspension

- Bit of a resonance issue at cruising speeds (from exhaust)

- Shifter will pop out of gear after about 5 min on the highway, or bit earlier if the road is a bit rough

What should I start looking at to fix?

Cheers...

If it happens when you back off more than likely you have a worn gear ( the one that pops out)

mine pops out of the tops gears, i have removed the gearboot and it helped for a while, but it still does it does that means the gears are destroyed? it maybe the 300rwkw goin through it though lol....

Yer you'll be looking at replacing the synchro hub assembly mate...won't know for sure until you pull apart the box but those are the symptoms that usually go with it. In a way it's good because there's no bullshit bandaid solution like using a different grade oil to silence problems, forcing you to repair it properly hehe :D

Bout $1000 to recondition it mate, plus the labour of pulling the gearbox out / installing it again. Oops, I just realised you aren't the OP that I originally addressed my questions to lol. Same problem anyway...

    • Yeh I think i'll message an old contact i had for ages that manages his own tyre shop now.. n tell him what i want n work with him before ordering..  Got this 17x9 +30 Driftteks on 245/45/17 PSR Drag Radials on the rear.. They fit well - for your reference in future - Rear guards  have been lipped in & minimal to non flaring of the rear Gaurds.    
    • If only it were that easy! I also needed to remove seats, shocks, brake calipers, send my car through a fence, and use measuring and ended up guessing because I didn't remove seats, shocks and brake calipers. It can be hard sometimes Can be a little more complex than 'just measure' if you want to truly measure the entire wheel through all of it's suspension travel. But if you aren't going for every last mm then yeah, you can check the space you currently have and guesstimate.
    • If you own a car, and it has wheels on it, and you know the offset of those wheels, and you have a measuring device, you have everything you need to work out if other wheels will fit.
    • Will this fit? but they are staggered set - RAYS 57DR SEMI GLOSS BLACK 18x8.5 +37 | 18x9.5 +38 5-114.3 STAGGERED SET   or If no go could just get a set 4's wheels of 18x8.5 +37 5-114.3 - would i run 8.5's 235s up front n 245's at the back if I do?   Thanks.        
    • Put a clamp on your return line. I have a feeling it's sucking air, and introducing bubbles to your fuel. With a lot of fuel, less problematic. I'd honestly be redoing all the lines in the tank and clamps on everything.   Also, you've given two different answers to the same question: Asked if being followed by the police you could get down to use the whole tank, you said yes you could, so long as you keep off boost. However, you then followed this up that free revving, it would also cause the issues. I'm doubting free revving is enough to make any noticeable boost on what is likely a decent sized turbo.   So now I have to ask, can you actually drive it lightly and use all the fuel, or does it break up even free revving? Also, have you put a fuel pressure gauge on it? Can you hear the pump change noise at all when you're having this issue?
