You cant argue though the HKS series one gears were decent.

The marterial was shit and the teeth wore down over time therefore making the Gen 1 gears the worst of the lot :banana:

bummer. my advice for ANYONE who fits ANY BRAND of cams gears is to check them 4 weeks after installation. being alloy there is always some 'give' in them. you tighten the bolts on installation but they can and do come loose. on one of my 32 GTRs. big build in japan. brand new crate motor, fully built from new, HKS turbos, 600ps all the good gear, cams, springs, head work blah blah blah. about 2 months after it was built we checked the cam gears. sure enough the bolts had loosened off. and these were tomei gears which run 5 bolts (i only use the 5 bolt jap gears, either tomei or trust). well worth checking.

Or just use stock modified gears :banana:

Were they HKS cam gears? Contrary to popular belief, not everything HKS puts out is even half way decent. I have seen their cam gears kill 2 motors. They only have 3 little bolts holding them in place. Really need to crank them little buggers down.

yeah, they really dont have a very god track record.... i went greddy because of this :banana:

I don't know what to tell you. I have seen two motors with bent valves that had an HKS cam gear which had slipped all the way to max adjustment. I doubt it was tuned that way and just a coincidence.

And HKS is really good at one thing with their parts. Adevertising. Nevermind, two things. Advertising and over charging for rebadging other peoples products.

bent valves. the pther problem i've seen with HKS cam gears is that shiny blue shit wears down/chips off, resulting in a tooth half the size of what it should be.

at this point, i'd guess its jumped a tooth (loss of power) then jumped another tooth and smashed valves.

I don't know why we are still discussing causes. the only way to suddenly get no compression everywhere is stuffed valves.

But you forgot the other very plausable option, some one stole his pistons.

lol very true....

maybe the gnomes that keep making hammering noises in my bottom end jump into his motor and took them

now we are getting some where, they stole his pistons and rods so they could do band practice in your sump.

This one time, at band camp............

Stop being silly.

You can't have band practice without the lead guitarist and that would mean his turbo would be f**ked too.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
