What set-up are you coming from?

What set-up are you coming from?

Done so far: 3" stainless turbo back. Fmic. Coilpacks. Fuel pump, ecu, digital boost controller, turbosmart stealth plumback bov, custom airbox, intake and exhaust cam gears.

Adding in this install:

Gtx3076 .82, injectors, fabricating 4" intake from custom box to turbo, fabricating stainless dump pipe to suit Garret housing, exhaust manifold gasket and bolts, powder coating everything black (turbo, piping, braided lines etc)

Er. I think that's it.

Will be intersted in gtx35r's

Such an evil stance

[krzysiu]

I'll have a gtx3582 on my car within a couple months. Coming from a gt3076r.

My GTX3071 finally arrived, the 1.06 rear housing is way too big but I may use it to jig up the adapter and pipes then try it out. Whats the worst that can happen, a bit of lag? Lazy to build boost?

[krzysiu]

Will be very laggy. Why did you get that housing? Silly choice :s unless it's going on a 5+ litre

[Rolls]

it'll be lag without the characteristic top end that laggy turbos have, it is just a simply mismatched turbo for the engine.

[JonnoHR31]

i think it'll work pretty well actually. would be similar to a 3076 with a 1.06 rear, which is what i have and its perfect on a 3L. would be a little laggy on a 2.5 but should still do nicely.

[zebra]

The VQ motors are a good thing and pump out plenty of exhaust gas, might work alright.

I say give it a go if you think you can live with it, would be great for your VQ35 build in the long run.

[Rolls]

oh I thought it was a 2.5L

[zebra]

It is a 2.5.

IIRC he is building a 3.5 to go in

[scotty nm35]

Thanks Zebra. Yep, it wont be too bad hopefully as im up around 4k whenever I hit the throttle.

It was the only Tial housing available unfortunately, even GCG are out. I will probably go the .82 when they are back in stock and hopefully the Vbands are the same size. Either way I needed this housing for the VQ35 build if I ever get the coin to progress it further. Parts are so cheap to import atm too damnit.

[KISIN]

turbo noob here, but is it possible to have a custom exhaust housing made up or rework another...eg for the gtx3071r and have a smaller divided then the tial .78 ? where and what would be the cost involved ?

[JonnoHR31]

why would you want smaller? would be a complete waste of a x71 compressor wheel

twin config ?

[JonnoHR31]

might be a little different in twins but i think with a smaller housing you'd find the rear housing would support a fair bit less power than the gtx71 compressor can flow. might be better off with normal 3071s and smaller housings

[GTScotT]

twin config ?

HKS T2 flanged housings, GCG stock them.

would those be the gt2835r ones ?

ps: would you guys think x71r in twin cofig with the t2 housing posted above would be semi-responsive (20ish psi no later then 4500)

No

[scotty nm35]

No chance, and the front housing is huge. (so is my Tial 1.06)

Im not sure it will all fit, I am going to have to mount the wastegate off the housing.
