Hey all,

I'm looking around for a dump+front pipe setup for an RB25 with stock turbo. I'm told a split dump will be better than bell-mouth as well.

From what i know there isn't much point going all out nuts on a stockie turbo, but i don't want to regret a cheapo purchase (i.e. JJR stainless) when something a little dearer is the better option (such as CES), i.e. adding an extra $100-200 and getting stainless, or ceramic coating.

I have a mild steel Fujitsubo cat-back at the moment with no plans for turbo upgrade for a while.

Any suggestions for a reliable, reasonably priced setup with the aim for a pansy 200rwkw?

Thanks :teehee:

Omar,

I just have the single 3 inch dump/front pipe in one.

Works well for me with my hi-flow turbo set up etc.

Before my hi-flow set up I was making just under 200rwkw with it.

However if you are planning further mods later (turbo upgrade) I'd now suggest a hi-flow cat also. I have standard cat with my set up and it is robbing me of some more grunt!!d'oh!

Also - I havent had the split pipe on before or done any testing so cannot compare !

I think Liz had both on her old 33 - hope she see's this thread :teehee:

Cheers,

Chris

I'd get one. Just unsure if there's better options.

Do you recommend JJR?

:yes: I was hoping maybe you could shed some light into the matter as i was looking at one myself haha, but if you had a good reason not to go there id keep hunting!

I guess it depends on what you want to spend! I mean the HKS front pipe alone is around $400, and with that you still have the stock dump pipe..

For the price personally it looks pretty dam good! Especially as its a split dump pipe, and front pipe in one. And will directly bolt up to OEM turbo and cat/decat.

Ill just go ahead and get it and let you know. :teehee:

Get one of these babies from AM Performance in SA, im sure he can send interstate, they do Split pipes in screamer style or return to exhaust which would be best for street. Quality is top notch and they wont leak between the turbine and the gate!

just adding to this thread, would it be beneficial to include having a small flex pipe in the dump/front pipe? gktech sell ones with flex pipes like this:

R33 front pipe with flex

ive also been looking at the JJR dumps but without a flex piece in the piping, just wondering if there is benefits with having the flex piece there?

Batmbl sell good ones Omar, Just japs are also fine.. Just as long as its not an xforce one you'll be fine.

Mines a custom ceramic coated one which is why It sounds so deep, so Id suggest it being ceramic coated, if you can find a second hand Ces one that would be good but unessasary as they are designed for some decent power.

The belmouth actually will flow more with bigger turbo applications, but the split dump makes the car sound better with a stock turbo.

If your like me with no need to upgrade the turbo then I think any will be fine if you ceramic coat them or heat wrap them.

A high flow cat is a obvious need too. I have the Catco one from Batmbl and it flows great, alot better than the stock one.. again dont get a xforce jobby.

They dont fit correctly, often never line up with themselves or other brands.

The cats dont flow at recommended amount, dont feel right.

Exhausts often stick out conciderable amounts from the rear bar of the car. but sound good.

So just a few points

I havent had anyproblems with mine. car makes 203rwkw with pfc on standard turbo so no flow issues either. Only thing i can say is it is quite loud. Might be bcos mine has a hotdog resonator instead of a proper mid oval style muffler. sounds great though.

Are you saying i should ceramic coat a stainless one too? Or is that just mild steel?

If you want to.. Mines stainless and ceramic coated.. looks slightly funny like a weird polished silver but you'll never see it.. Just drops temps in the engine bay.

The xforce cats are really bad at flow.. but thats a nice power figure.

So Nat you're saying i.e. buy a JJR and get it ceramic coated?

Sounds like a decent idea actually.

Yeah cat is on the list too. Hoping RSPCA can get me a cheap one.

I checked BATMBL on SAU and saw their split dump+front pipe. Looks pretty good, but you said yours is custom? What did they do differently, the coating you mean? I'm happy to add $100 over JJR and get the BATMBL one, sounds better quality steel (plus you recommend).

So the Catco was good for you? I'm not gonna go nuts on a cat (i.e. i'm not fussed if its ceramic/metal) cause i'm not gonna upgrade the turbo for a while, if ever (he says with a hint of doubt lol)

Are you anal like some of the other SAUers and insist on a metal pussy?

Convince me and after my exhaust manifold is fixed (next week) i'll head straight for the turbo-back :D

Good to have some advice drawn from experience ;)

On the dyno my CES dump actually brought boost on quicker and made more top-end than the bellmouth....they both tragically had boost drop-off, but hey that was related to a sucky-closed intake pipe :S

So you'd recommend a CES dump+front??

Yeh i was thinking it wouldn't make a big difference. I'm gonna stick with a split dump. Just wanna pick a good all rounder.

Hey, i just ordered my JJR one in stainless, when it arrives.. (maybe a week) ill let you know how it goes.

Thanks mate, i'm interested. If it's a great bit of kit then its a steal. I need convincing cheaper=better :)

    • It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....
    • Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
    • So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.
    • Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
