Darrin, as far as I am aware, you need a split dump for an R34 to fit the Stagea, thats why your pipe wouldn't have fitted. Just Jap only lists them for R32 and R33 GTS-T and the one I bought for my R32 some time ago fitted straight up, with none of the issues you have mentioned, and I checked it the other day while my car was up on the hoist and everything in a-ok.

I have no dealt they fit R32 and r33, because that is what they were designed for.

I had no problem with having to extend the vertical section to miss the floor, but I do have a problem with the warped flange. I am not prepared to fill the gap with sealant. It is that bad.

When I ordered the pipe thru JJ, Daron was not sure which one exactly fits and had mixed reports from customers. So he agreed to send me with with the chance of a refund if it did not work. so that thats what will happen.

R34 dump pipe is longer by approx 20-30mm and has a extra mounting bracket which could be cut off if not needed. I have not measured or compared one to a R33, but that is what I have been told by JJ

All the people that have fitted some sort of dump to a Stagea have used R33 ones.

Just to be clear, this thread is not to put down Justjap's products or quality, but to simply find a solution to my problem. Justjap's understanding and service has been great.

So bascially I am back to square one.

their service is good, quality is generally 80% good tho..... with my bellmouth had to have the flange rewelded, too many gaps due to shitpoor quality weld. didnt cost much.

flows real well, and fits fine :laughing-smiley-014:

This pic is the JJR split dump. Note that the pipe is straight as circled and this is where it hits the car.

The second pic is JJR bell mouth design. Note the is a offset in the straight pipe which should miss the car

This could be the problem?

Also spoke to Bosimporting and they told me that I need a R34 dump for the series 2 and r33 dump for the series 1.

This does not make sense as they are they same floor pan and the motor and turbo are in the same position.

But the r34GTT dump is 20-30mm longer in length and the cat is also longer in a r34 GTT. So why would it fit?

Had a look and compared a R34gtt bosimporting non split dump pipe tonight to the R33 JJR split I current have

The R34 dump was approx 100mm longer than the R33 one.

Also compared the R33 JJR pipe to the standard series 2 factory exhaust and the length from the turbo to cat flange was the same.

So a R34 will not fit.

Will have to find a R33 one that will miss the floor.

I finally got a dump pipe to fit

I used a R33 Xforce bell mouth dump pipe

Fitted pretty good, but had to create a bit more clearance by removing approx 3-4 mm from the end of the gearbox cross member and massage the floor where the gearbox cross member bolts on.

Pic to follow. . .

what a PITA process that has been.

did we end up confirming anything to fit a S1?

I've got mine ready to be put on, Duncan. Care to help me? I've got the jack, stands, tools and the space - I just wish the garage wasn't so bloody cold!

S1 would be the same

The main thing learnt out of this, is what ever dump you use it must set down lower to clear the floor and then set back up to cat converter, ie not run straight to the cat.

I have a BOS imports split dump to go on, I know of at least one Stagea S1 owner that has fitted one of these with no issues so I will let you know how I go. The section of pipe heading towards the cat definitely does have a dip in it though so maybe that is the difference...

I spoke with Bos importing aswell. He tried to tell me I needed a r34 dump for my series 2 not a r33.

R34 dumps are longer and a different shape under the car. It would have not fitted. Another SAU member in Brisbane has a R34 Bos pipe for sale which I had a look at and it would not have worked

I also spoke with Alexcim about his Bos R33 split on his car and even though it fitted, it still had clearance problems. Also spoke with Rev210 about his JJR split on his car and he had clearance issues aswell even though he still fitted it.

So out of all this, until someone makes a stagea specific dump pipe, the ones that are off the shelf for r33's are not a perfect fit.

so after all this, does anyone have a surplus mild steel bellmouth dump/front to suit r33 they need to sell, to me, cheap?

No, but I have 2 shiney s/steel split dumps, never used for R33's

That is what I used, but not cheap in s/steel $350

nah, just jap brand, stainless steel $220 delivered.

thats what I have. got it 2 yrs ago..... off ebay JustJap store.

needed slight alteration to the welded seam on the bellmouth (gaps), cost bugga all ($100 incl fitment)

They only have the split type for $250 and the Xforce bell mouth for $330 now

You can also now get the s/steel split type (same as the JJR one) for $199 on ebay from another seller, but only good for r32/r33

Installed my BOS stainless split on the weekend with NO clearance or alignment issues. This is on an S1 and is a fairly late model split pipe, so it worked for me, which I am really happy about.

Note the huge clearance between the pipe and the aircon line, this is one of the things that was changed in the design of the split.

It comes close to the rear gearbox cross member but not too close, it won't hit it. The exhaust could be 40mm longer on total to be perfect but it's pretty good, just pulling forward on the rear hanging points a little and it is close to the rear sub-frame due to this. On a quick test drive nothing touched or rattled so I'm pretty happy with it as is.

    • Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy. 
    • New [400]Z, they're available in manual and you don't have to worry about parts scarcity. 
    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
