External Wastegate

[jason.bored]

Hey guys need some knowledge here.

I want to run an external wastegate on my rb20det. I was originally and still want to weld it to my stock manifold but the position where I wanted to put it (on top of the manifold) the intake pipe gets in the way.so I thought how much to the right can I move over but it's too much that it's on a bend.

Is there anywhere else that I can weld it to the manifold that it won't b in the way of anything?

And does it matter where it's positioned for flow purposes?

Ur help is much appreciated

Thanks

Jason

What turbo do you have? You can put on your turbo housing aswell.

PM dilf*kn he has done it on his 25 to his stock maniflod he might be able to send you a pic so you can see

The best place is on the turbo housing - flow does matter for boost control.

Anywhere on the rear housing???

Anyone know who can weld this up in Melbourne coz I few said they didn't want to do it???

Pm hypergear he made some of hes turbos with the waste gate on the housing Im sure he can mod yours.

+1 for welding it straight to the exh housing,

that is the best option.

where are you located?

i can forward you to a guy who did the mod for me on my old turbo.

Pm me your phone number and I'll mms you pics of

My set up. I have a gate welded up to the standard manifold with a gt3076 hanging of the side. I've never had boost control problems.

i asked around a few places and none of them wanted to do the job due to it being cast iron and they can't guarantee the work or if it will even turn out properly.

who did the weld job for you JKR-32 and how much did it cost ya?

pm sent.

edit: looks good man, is that a steal pipe running of the manifold to suit a 38mm ext gate?

has anyone tried fitting a 40mm ext gate off the manifold or turbo housing?

[JKR-32]

My mechanic done the work mate. Not sure what diameter pipe actually. But its ha the old style turbo smart 45mm pro gate hanging off it. Brad does all my mechanical, fabrication and tuning. Handy bloke, but as is always the case with good mechanics, it's a jump in line type senario. Not sure on price, because he done the turbo swap, intake pipe, and dump pipe all at the same time as the gate. Along with a few other things.

[dori34]

this guy fit one and looks like it'll clear the intake pipe from the TB as well;

IIRC Nytsky's GT35R setup was running the gate off the exhaust housing - you can see it in his avatar picture of his engine bay!

here was my old turbo setup with the gate welded straight to the exhast housing

[jason.bored]

Yer I dOnt really want to weld it to the exhaust housing just incase I need to changed turbo or something like that, that's y I want it on the manifold.but it's hat to find someone to do it as being said it's cast iron an all and ppl can't guarantee the welds.even though I'm sure if it's done the proper way an no shortcuts that it will hold. Does anyone know anyone in melbounre that will weld it??? Pref in northern suburbs???
