The last 304 3 inch 90's I bought were $25 each.

I usually lobster my bends but the Brobo I have wont cut bigger than 3.5 inch. I have a couple of big power systems to make soon and would have to get mandrels for it but how the hell do people clear speed humps with over 100mm of pipe hanging under the car? I think I will instead make oval tubing, say 3 x 6 inch, hopefully the owners will agree...

Hey guys

got the GTR goin into the exhuast within the next couple of days and trying to get a figure on how much i should be paying...

the set up is a single high mount borg warner on a twinscroll manifold

Basically the work i need done is a

4 inch v-band dump pipe to the cat

plumb the two wastegates into the exhuast

setting up the plumbing from compressor side of the turbo to the intercooler

im guessin stainless will be the way to go?

any input is welcome

cheers

The guy they use is really good, so dont stress over that.

I'd go stainless, it's more costly but when it comes to GTR's the phrase "Do it once, do it right" always springs to mind

You didnt do very well in maths at school right? Double? Lol

For example a 90 3" mandrel in ss is 3 times the price of ms.

Please post pics of the completed job so we can all drool.

Yeah they cost about $35-$40 if you buy them at a wholesaler

Retail somewhere about $60 ofr a 90 bend

If you can provide me details of your stainless pipe supplier I would greatly appreciate it. I'm clearly paying too much from Tubesales. I only buy small quantities but if you can get them at half the price then it would be worth my while getting them freighted up here. I do a fair bit of custom exhaust work here.

Just finished a 4inch full system on a 34GTR. He supplied the manifold and gate etc and it uses that flexible stuff you guys are talking about. Looks like rows hooked into each other. Seems to work pretty well and the heat coating we had done didn't affect it negatively and its strength is good too. Makes wastegate plumbing very easy.

For other options, we use a 2inch flexible bellows - they are like a braid outer with a spring inside to bend. Makes aligning Vbands a sexual experience

wow when i get the stainless bends of my mate ( not sure of the supplier it was only 10-20 dollars dearer then MS ?) 304 grade ? anyway my friend has the flexi tubing on the end of his wastegate pipe so he can plumb it in or leave it vent to the atmosphere works great and excellent idea!!

Well thats it isnt it.. definatly dont want the job to look like sh!t and i dont wanna have to come back and do it again

Do u know the name exhaust shop they use Steve? have u delt with them before?

Ill go the stainless cause i will be happier with the look no doubt

will be asking about this flexible hose as well Dan

Yavuz is booked out for a while yet.... whats another 3 weeks after already having the car off the road for 15 months :thumbsup:

fairly certain ive already got Brads number.. hes doin up a custom catch can for me when im ready

Righto, has been a while since i posted this thread

car is now at the exhaust shop and is close to being finnished,

Hack from performance exhnaust in Northmead is doing the work and from what i can see so far he has done a great job

Ive got some pics of the dump and cat, with wastegate pics to follow soon

cheers mate,

Do have plans on going to a few events, (somthing coming up on the 19th of Feb?)

anyway Paul and Steve-O have my event calander planned lol

will probably just tag along to what ever they do :thumbsup:

righto exhaust job is nearly done... here's some more pics, not everything is bolted up yet so gives a good idea of what the pipes look like

For those interested in how much its costing all up PM me and ill let you know

cheers

    • Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.  
    • Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly
    • oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)
    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
