I have just this week noticed that when my R33 GTS-T hits boost (only 10 psi) at around 3000rpm in 4th or 5th gear (under moderate to heavy throttle) that the revs initially rise quickly (without as much thrust!) and then dip slightly before continuing to boost OK...

Could this be the clutch slipping???

It feels a lot like it, but I've only ever blown clutches (admittedly in FWD cars) in lower gears and usually when revs are high!!!

Is it the torque that causes the clutch to slip??? It doesn't slip and dip in any lower gears!!!

Could it be a boost pressure issue??? I have a basic bleed valve installed. I can't think why this would cause this but I'm certainly no mechanic!!!

IDEAS??? I already did some searches and came up empty!!!

Ta!

Bummmmmmmer........

So, anyone know a decent place to price a clutch up here in Brissie???

I don't think I can afford a heavy duty clutch if they're $900 fitted!!!

How much do the standard clutches go for, including fitting, and ...

where should I get one???

I hardly ever drop the clutch in first, but I don't want it to blow again inside a couple of years either. Would I be better with a heavy duty item??? I'm only producing around 140KW atw...

Suggestions...

PS Hey, how long, if I nurse it somewhat, until it will give up altogether???

Iijj , quote for me was 350 for standard clutch and 550 for heavy duty. twin plates go up and up from there... i plan on making more than 200RWKW so a heavy duty is rated to the 300 rwkw range. If i wanted to make over 300 RWKW (read many $$$$$) I'd have gone for a twin or Triple plate item.

Personally get the best you can afford, cause there's nothing worse than making more power and the stock car parts can't handle it ;)..... I guess that's half the fun tho...:D

If anyone else knows of a good shop in Bris North, speak up!!!

Thanks!!!

Try x-clutches they have been in Zoom magazine, they are in QLD and at underwood somewhere.

They have stock, heavy duty twin plates tripple plates, they are made here in Australia using stuff they don't tell anyone.

In Zoom they had a silvia or skyline doing around 400-500HP, and ask x-clutches about what to get and they said get our special coated stock plate and it'll handle it.

Anyway sus them out.

      M35 Brake caliper replacement

      By Waders360 · Posted

      Hi from Canada, Both of my calipers are starting to fail. My car is a 2005 M35 Stagea ARX and I can't seem to find any parts or any cross reference caliper that would fit my car. Is there a company or a similar caliper that would fit and I could replace the OEM one. Or if anyone knows where I can find a new OEM. Any help is very appreciated. Let me know!

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.
