I'm pretty sure they are what I've got except pained in black with added external gate port, as all the welding patterns are the same.

The goal is to supply a kit that keeps every customers at my test car's performance at a budget price. As mentioned earlier, I'm investing a fair amount in re-developing the current TDxx series of turbochargers, manifold and gate are crucial.

they have copied the stainless ones and remade them in steampipe..like what you are going to do.

This is just a FYI for anyone going to buy a JJR 3inch dump pipe.

Did a paper gasket outlining the outlet of the SS2 turbo. Below is the difference in size:

I will be getting the dump pipe fixed up to make it flow better

[blah_blah]

Yeah no money for that

Heard custom ones are really exy

The JJR one only cost $170

[Hanaldo]

My JJR one matches my gasket perfectly?

[GTScotT]

Seeing as stao makes his based on the OEM gasket I'd say the JJR dumps have started slipping in quality. Usually the machinery needs to be renewed and replaced every so often to keep the standard the same. That sort of thing is a secondary priority to a cheap offshore supplier.

I have seen things that have holes etc punched end up under diameter as tooling wears etc, but profiled flanges be it water cut, laser cut, plasma cut etc etc wont generally have tolerance issues. More than likely the machined adaptor is a little out. Better too much meat that you can grind back then not enough material.

Just a question...doesnt tao machine the fark out of the flange on the turbo. So the dump wont match up..

Has anyone else with an SS serise done what Tony is doing?

Tony do u have a stock gasket around to compare to?

Here is a stock gasket on the SS2. pretty much perfect. Got jibbed on the JJR dump/front pipe

[ssxRicho]

Contact jjr. That is pure shit. Nothing else.

I've got one and it's fine.

Good luck getting the bolts in with it like that though...

[GTScotT]

Lol just needs to rotate the gasket a little, you can tell its right tho

[Roy]

That's woeful! I take back what i said....

Thought some of the guys in here might be interested in this. Video I took earlier today of me in my R34 with ATR43 G3 (350rwhp) vs Jay-rod in his R34 with ATR43 G2.5 (340rwhp):

Mine was pretty well spot on but my jjr dump is 6 or 7 yrs old. Just gave it a quick clean up with a grinder and angled the inside edge of the flange.

Sounds like a dodgy one

[hypergear]

Good to see some one actually done a trace. That dump pipe don't look good, I hope the actual pipe is welded outside of where the flange is, or there will be a big gap once die-grinded. Its going to make discharging of air more difficult, which its already hard getting enough out of the Nissan 6 bolt pattern. I would definitely get that exchanged/fixed before turbo installation. Just got to admit that if you want some thing done properly you must do it your self. I'll be making a Vband / two bolt type 4inch front/dump pipe for all ATR43 turbochargers replacing the current Nissan 6bolt dumps in very near future.

Made and trailed a Dual Ceramic roller SS2 today. (took me 3 hours to balance, with all the extra bearing collars)

The sample manifold looks not too bad and haven't cracked yet with 22psi. There is a just noticeable off boost response using the roller setup. I will make a few for those interested in evaluation at the normal price.

Shiiiiiiiiiiiiiiiiiiiit, I wish my car had been ready for this years Powercruise. I did finally get the engine installed today though! Lots more to do though

Nah PE in Ringwood would have made a good 3 inch bellmouth out of the standard dump flange for sweet fk all. My entire exhaust from them was $600 with me supplying a Varex!

[kosmo90]

Yes I've fitted the prototype manifold. It is awful, lots of dressing up work required and i'm certainly not impressed with the level of workmanship, the final product I will be selling will be a steam pipe manifold with every thing done to specifications. it will definitely flow much better then a stock Rb25det manifold.

How long before these are ready and how much? i've just snapped a manifold bolt and it's stinking the car out now.

Just wondering if i should re-bolt it or upgrade
