I have a GTR r33.

Im looking for some new dumps.

They all look very much the same to me...

Is there any major differances between the major brands eg trust, Hks, Tomei etc?

Is it worth getting one over another?

Im going to get a set of 2860s turbos of some description to go wid the dumps

I have the tomei ones they look awesome, if they work half as good as they look it will be good, fit perfect also. I picked them up for 600 for the pair new. I dont like the HKS split ones (or their copies) as the main feed it too small in my opinion and the single large dump works better.

I too like the Tomei ones

Stock ones are pretty good (in fact - really good) - not too keen on the HKS ones.

Apparently Nismo make a cast 1 piece one as well - $$$$ I am guessing.

Also there is HPI - though they look pretty similar to tomei...

Yer i like the Tomei ones, they look hot shame u cant see them lol

600 good price to!

there are plenty of choices. The stock dump pipes are restrictive and the exhaust housing of the turbo often has overlap on the dump flange making it really need a good port matching.

Hard to go wrong except for the el'cheapo china units. They often need work to align the flanges and as a result may bolt on and actually perform worse than stock.

Hpi, mines, tomei, oodles of choices. Look around for second handies for the bargain buys, as long as it is made of decent stainless and the flanges are true you can't go wrong.

I picked up a set of mines dumps and apexi front, all second hand stanless for 400 delivered. Might not be as nice as a new shiny pipe, but how long is your new shiny pipe going to look that way? I can't even see any of it so looks don't matter much.

I dont see the point in the tomei units...fair enough they look mint. Who here is using them with a twin 3inch into one front pipe? Cos if youre not theres no point in having a dump with a 3inch outlet....

Just buy the Just Jap split stainless dumps. A bit less turbulence that stockers in the gate pipe and same 2.5 inch outlet, same size as most aftermarket front pipes. Makes perfect sense. The JJ ones fit perfectly too.

Dont buy ebay ones. They dont fit. Theyre a throwaway. Tried myself LOL.

Oh, and the tomei manifolds look mint too. But the cast stockers match ported do the same job and are half the price at the end of the day. And stronger. And wont ever crack.

The JJ ones are shite. And will be worse than stock if you aren't bothered to check the matching of the flange to the turbos and get rid of the overlaps.

When they do bolt on they have rather crappy flange alignment so unless you like poor flow you get the die grinder out for a few hours. I've now seen enough of these to know quality control is an afterthought.

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.

      A bit late but A disk S13P fit over stock R32 GTR brakes, usually A disk front, O disk rear works.

      Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.

      Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
