Gt30Iw Fitting Hardware , Whats Good/bad/ugly ?

[discopotato03]

It seems Garrett GT30xxRs are popular upgrades on RB25s but they don't just fall in so I'd like to know whats the best bits to make it happen . Basically you need a dump pipe and an inlet pipe and a spacer plate to get the compressor housing off the exhaust manifold . Then you'll need longer mounting studs and plumb oil and coolant in/out .

Someone here mentioned that Liverpool Exhausts make a nice one piece dump and front pipe so that would be handy . It looks like like the easiest suction side would be a 90 degree 4" to 3" silicon or rubber bend and some sort of steel/aluminium/stainless tube section to connect the plumbing and AFM . I say AFM because some people like have something that looks like its doing something and connects to the std airbox .

I don't know how inconspicious you can make a GT30R but the more the better IMO .

So , can we have some examples of what/whos bits people have used to fit these turbos to RB25s .

Cheers A .

A bright blue silicone bend won't be conspicuous, lol, but seriously if you run a silicone 90 off the front it will suck in on boost. You need a stainless or alloy hardpipe intake, that much has never changed.

[discopotato03]

Don't like blue as in silicon or uniforms . It would have been black or preferably flat black .

I did find in Mick o's thread a pic of his dump/front pipe .

I like bell mouthed ones myself .

Does anyone have pics of an install that retains the std airbox and possibly the MAF ?

Cheers A .

black silicon joiners for intake hardpipe , powercoat black 3 inch metal intake and comp cover of turbo , and remake a turbo heatsheild from the ACL shit

you can completly hide the big comp cover with the ACl stuff ... easy..will look stock to anyone except skyline heads, you can even

hide a 38mm gate of exhaust housing easy with that stuff, Im doing it atm, just waiting for stuff to come back from powdercoaters

then i have a made up airbox, that hides the Boost control solenoid, oil catch can and radiator overflow

cheers

A pic of one of my intakes , sent in by a customer. They suit the stock afm, airbox, bov and breather return. Painted black you can't pick it from stock.

That's on a stock turbo though isn't it Scott? DP is specifically wondering about whether that could be done with a GT30 on a spacer plate off the stock manifold. Obviously it's just a tweak to the design, seeing as shit won't move far, but it appears he needs reassurance.

Attached are photos of my intake pipe, linking my Z32 to my Hypergear with a breather in between.

The pipe was made by Mick_O, who is an absolute perfectionist when it comes to this. He's in the west and I believe he will be happy to fab one for a fee for anyone interested.

The welds were done to a colouring and finish that i requested. He noted and showed me that he can also make the pipe to have no marks or burn colour. The pipes are also made from medical/food grade stainless bits, all butt welded except on the 20mm bung (no filler wire).

You can obviously prep that and paint is fluro pink if you like. Matte black wouldn't be hard either.

Yep, works on any turbo in the stock location (low mount). 80mm alloy should be good for well over 350wkw.

I have a GT30(hypergear but same size/comp cover) /spacer plate and scotty intake pipe disco..all good, looks stock

I use a 4" - 3" reducer off the turbo, 3" 90º stainless bend, 45º silicon and 3" stainless 45º bend to the afm. I use a custom airbox as I experienced lots of stalling when backing off the throttle with just the 90º bend. Then the usual spacer, dump/front, solid oil drain and braided oil feed. Seems to work.

Thanks for the plug Jase my dump was a Liverpool exhaust made item disco which i was lucky enough to score off mtq. I can knock you up anything you need mate. Its kinda what i do lol

[discopotato03]

Well I basically wants a "suction" pipe made to line up with the GT3076Rs (same dimensionally as your GTX3071R) in stealth black . Aluminium would be nice because it won't rust internally .

I also need a dump/front to suit the GT30 0.82 AR IW turbine housing , I have a large body 3" Catco 8007 in the std location and it fitted the std front pipe .

I was speaking to the feller I wanted to fit this turbo today but he's a one man band booked out for weeks servicing daily drivers .

I reckon with the main bits made changing over shouldn't take that long . I intend to reuse the GTRSs oil and water lines because they fit the same .

Mick do you still have your Z32 and airbox ? If so would you consider making me the inlet section using yours as a template ?

Couple of things I was wondering about . I always thought thermal wrapping stainless was no issue and my old dead Subies fabbed stainless header was like this . I was told today that wrapping staino would make it harden and crack though thats not what I've found in the past . It would be good to keep the heat out of the bay and in the gas with the dump/front pipe .

Also whats the go with longer manifold studs , does anyone make anything OE std ?

Cheers A .

Ford falcon ones fit up nicely disco ...

[scotty nm35]

I wrap all my stainless dumps, I have never had any come back.

I think they are talking about thin stainless exhaust manifolds, as I have seen them glow white hot before. Not something you would want to heat wrap.

Does your suction pipe require bov/breather fittings also?

[GTScotT]

If you do get Mick to fab your stuff I can arrange to be on site and do your wrenching.

[discopotato03]

I'd like to fit all the std breather and recirc lines because mine is std in those areas .

Sounds good Scott .

Back tonight , cheers A .

or peugeot

[discopotato03]

So they both use longer suitable studs ?

A .

[ARTZ]

yeah mate, if you take your studs out, go to an exhaust shop and say you want some the same but 10mm Longer they will give you falcon manifold studs...

Sorry bout the slow reply disco but i have sold my car and all the parts too so need another 33 to work on mate

I dont do much alloy work tbh stainless is what i work with and it wont rust internally either btw
