3" Turbo Back Dilemma

[david]

hi guy's, i'm thinking of getting my 3" turbo back custom made.i've got someone to do it for me,but he can only weld the 3"inch just below the wastegate instead of directly behind the turbo.what do you guy's think? i know there's been alot of thread on turbo back,but your imput and advise will be most welcome.

Mine's the same as that. You could have a 2.5" to 3" cone welded to the turbo flange? Won't make a massive difference IMO unless you're going for silly power where a 3.5" DP would be better suited anyway...

that's exactly what i've ordered,2.5" to 3" cone measuring 3" in length.
so that should not restrict the turbo then?

I'm in similar position, though I'm strongly considering purchasing a TIG welder and the materials and making the system myself. the amount of money it takes to get a system made would more than cover this and I want a decent welding set up anyway.

Regarding where to take the down pipe to 3", as Andy points out it won't make a whole lot of difference if you go 3" after the waste gate pipe and it makes it a lot easier to fabricate. Though personally I want mine to be 3" from as close to the turbo as possible with a separate waste gate pipe venting too atmosphere .

i think you save alot of money and hassle me self,if go just below the waste gate.like Rusty said it won't make alot of difference unless your're going for massive power.

purchasing a TIG welder is a good way to go,as i 'm thinking thesame way.i recently purchase a 5 meter 3" stainless of material including p&p for £80

That's a seems a very a good price for the pipe, do you know what grade stainless it is? ie 304, 314, 316 ect.

yeah sorry i for got to mention it,304
the things that cost is the 45 and 90 degree bends.

Thanks, just adding it up in my head £350 should cover the materials then, if you want a single rear box system with a felxi join at the end of the down pipe. Depending on what you go for a second hand TIG set up could cost you anything between £200/£500 and would be generally useful piece of kit. Beats paying the best part of a grand for custom system I reckon.

That's where I've been looking, just waiting for funds and for something suitable to come up relativity close as I want to be able to see it working before I part with any cash.
