I have a rb26, running stock turbo but plan on upgrading to newer twin turbo.

I was wondering if anyone dynoed their dump pipe to see if all those 700$ nismo,tomei,mine's dump pipe are worth the expensive price or better put the money elsewhere..

Any dyno chart to back it up!?

Thanks a lot guys!

Yeah if you can get R34 GTR dump pipes grab them and save your money, but everyone has cottoned on to this and R34 GTR owners seem to be keeping their dump pipes. How selfish!

How much should I expect for the r34 ? Because I can get mine's for approx. 200$ ( I think the guy don't know how much it's worth hahah!)

By the way, I have a R32 GTR.

i got Mines dump pipes when i had my R32 turbos changed for 2860-5's.

i dont think that the dump pipes really make much of a difference, the sound was a little different thats all really.

i paid 350 second hand to have them installed along with my turbos.

not too bad, but still not cheap.

but at least it wasnt what they're asking for them brand new.

I think they do a bit more than just change the sound. :happy:

sorry, it was on an sr20

but you'd think it says a fair bit about dump pipe design across all engines/turbos

unfortunatly the thread got deleted as one of the companies who's got tested complained or something.. sigh

you own a GTR, what costs as little as $200 that will make any REAL power difference.

it made a difference to how it sounded when on full boost, and it probably made some small difference in power.

who really cares, it got done when i had the turbo's changed as most GTR owners do unless they got R34 dumps already.

there are probably other things that it helps like flowing more gas and heat from the turbo's.

i dont have dyno sheets to back my power up, just giving my honest opinion.

if you wanna change your dump pipes you can, if you dont its not going to make a real difference. its just whether you want to spend the money or not.

Unfortunately - that is a big fat no!

R33 dumps i've also been told by a little biride have done 380rwkw as well, 20psi.

Identical result to cars with Tomei dumps, R34 dumps etc. So there is certainly no issue neccesarily.

I have factory R33 or R32 dumps on mine - 280rwkw @ just over 1bar.

identical result as before when i had much larger trust split dumps on there. I had to sell them due to ride height problems, otehrwise i guess i'd never have seen it.

I'll make around 330rwkw @ 20psi, which is the norm for GT-SS's, plenty of setups with stock dumps have done that with ease.

The car in question that makes a claimed 380RWKW would be mine and, yes it uses factory R33 dump pipes. But for that price l would give them a go. If you see no gain you can always sell them and get your money back. Although my car makes the above mentioned power, l am thinking of buying a set of trust extention pipes as l have been offered a set at a good price. looking at after market dump pipes compared to the standard ones, the after market dumps you would think would make some type of power gain.

hmm, they may be able to handle 380kw but what about the dyno sheets comparing the different dumps? i think the advantage of well designed dumps was faster spool and more torque,, not really raw power

my mate who is pretty "in the know" sent his aftermarket dumps to CES to get honed out a bit more too

but yeah im not the expert just going of what ive read

^ well when this "birdie" is one of the most experienced RB tuners in the country, if he tells me it's as good as a aftermarket dump - fitted car...

I'm highly inclined to believe such a statement. If i remember to get some dyno sheets @ some point (details removed), then ill get a hold of them.

I'm not for a second saying a R33 GTS-t (or SR20's) for example, see's no benefit. Just the example we are talking about at hand doesn't

I went with R34 because they were 2x cheaper the price of the mine's ( 2 peoples were selling an used set).

Thanks for the head up. I'm sure it will be better than my stock one!

Also, Tomei diameter is 60mm just like the r34. So, beside the material, I can't see a difference.

By the way, just to make sure, are the r34 dump bolt-on on the bnr32 ?

      I need more than help to finish my R33

      By marni · Posted

      Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄

      Hmm. I've gotten pretty good outcomes from talking to them about things that I've had go wrong or ideas for improvement. Have had a lot to say about the R32 FUCAs, and they have sent out some replacement parts for those, gratis, on a couple of occasions. Mind you, I have bought a couple hundreds of $ of replacement rod ends for them too!
