hey guys,

I just got my clutch changed on my R33 GTS-T 1995, it had the original Nissan clutch on previously, I changed it to an excedy heavy duty clutch (organic) . Now I feel like I have lost a bit of power, the car is still running great besides that small loss of power esp. in between shifts, it feels like it takes a while to get going after changing from 1st to 2nd and from 2nd to third etccc..(CLUTCH IS NOT SLIPPING THO) but once I get past that stage it feels like my car again..

I have spoke to a few guys and they all say that the clutch has nothing to do with loss or gain of power. What do you guys think ?? is it all in my head or what

Thanks guys

Amer

I dont think its anything to do with the clutch, because I have heard all positive feedback about it.. maybe the way my mechanic installed it ?? I dunno mybe its in my head..

Anyone had this experience??? or maybe the oposite or no change ??? feedback would be very much appreciated.

I had my clutch replaced the other day (a PVR/PBR heavy duty 'normal' clutch.. can't remember) and have the EXACT same thing. It's nearly like a 'pre-lag' just after a gear change and YES it feels like a loss in power. Mine's p1ss1ing me off. I also have the "CLUNK!" noise from the diff/driveline when playing around with the clutch pedal catch point while reversing. Another annoying 'quirk' to this car :P I'm gonna have a transmission person look at it, cos although my mechanic has the exact same clutch in the exact same car, it never used to do it, and it annoys me too much to leave as is.

heavy duty clutches are only different to OEM clutches( assuming its organic ) in that the clamping load is higher and the pressure plate is usually forged and not just cast like on a normal one.

I'd say its probably in your head man... my car is getting slower everyday need more power eh ;)

Well, seeing as one of my mechanics took it for a drive with me and could feel what I was talking about, it's not in my head. He did say his cars (R33's) both had it too, but I don't think it's something they're supposed to have, as I've never felt it before until the last few months. It just makes the car feel sloppy in a straight line and annoys me. I'll be chasing it down.

OK, I had a new mechanic look at and drive it today, and he reckons he knows what it is. He wanted to put it up on the hoist to confirm, so I'll go back in a few days time. But he reckons (watch out, incorrect part naming to follow, I'm no mechanic!): on the same little arm thing which has the "throw-out bearing" on one end, there is a pin that holds a bolt with a ball-end. He said it is not uncommon for that bolt to snap so that the pin is the only thing holding it there and for many mechanics to not realise the problem when working in the area. In fact the installer has the same car and clutch, so I'm sure he'll be over the moon to hear that he has a problem hahahah. And what happens is the pin makes a 'crack'ing noise when it smacks back into the ball-end. If this is the cause, I'll go back to the installer (Dynotune... don't ask) to get them to fix it for free.

Coincidentally, I'm gonna get some upgrades in the coming months and this bloke also said the clutch won't be good enough for the power I'll make. Luckily he only charges $450 to go in and do clutch work. Anyone foresee the need for a spare clutch capable of ~210rwkw in the next few months? Would be fine for any stockish R33, mine has 150kw at the moment, but going for about 250kw or so.

I have the same clutch in the same car... I get the jolting noises when reversing, and it feels a little laggy when changing... but I put that down to the fact that the clutch it grabbing COMPLETELY when you change gears, rather than slipping a bit and keeping the engine revs higher. My other clutch was VERY dead when I had the new one put in.

I had my guy put in a nismo... um... now i've forgotten what it is called. Pivot ball? The bolt I think you're talking about. It's a thicker unit than the standard, and even though my standard one wasn't dead, I thought it a worthwhile piece of insurance.

I had my guy put in a nismo

So is the clicking noise gone now?

And how about the hesitation after changing gears?

I'm waiting back for clutch availability but hoping you found this fixed it. If so, we're NOT crazy or paranoid!

    • The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
    • I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.
    • Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.
    • Thanks @jtha7 I will have a look around tomorrow but it is a prick of a spot. These are some photos i tried taking 
    • I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
