Hypergear

[kspots08]

Hey guys.

I'm currently contemplating buying a .63 rear housing (internally gated and v-band dump) for my 35/40 off Hypergear. Just wondering if anyone has used them in the past and where they happy with what they got.

Is it brand new gear that you get off them or just reconditioned parts and housings? I will probably end up going with them as it seems to be my best option at the moment.

Plenty of threads in the FI section mate, please go have a search.

Having said that, a .63 is FAR too small and a very bad choice for a 700hp/GT35

[kspots08]

Thanks mate will have a look now.

With the .82 i have at the moment it iust just too laggy coming on boost. Im hoping that this will make it come up on boost much quicker.

Get a smaller turbo then.

Putting a .63 on a GT35 will cause undue restriction, and it won't improve things "much" better.

Yeah was thinking of buying a smaller turbo, but dont really have the funds at the moment to do so. I thought i may as well do with what i got at the moment.

Why would Garrett sell a GT35 turbo with a .63 rear housing option if it is not a real good option??

ask RUFFLS

Because they already have the housing.

Offering an option is merely adding to product coverage.

The .63 has its place. But not on a RB25 with a 700hp turbo mate.

By the sound of it you'd be better off with a GT3071 which even in a .82 - would come on sooner than a GT35 with a .63 and be MUCH more linear and progressive (read: less epic wheel spin as boost hits)

Hypergear can provide you with what you want, from what i've seen all the housings etc he has are brand new, not reconditioned

but Ash is spot on the money, the turbo you have is better matched to a 3 - 4 Litre engine, not a 2.5L

and i understand you may not have the funds, but trying to make the turbo you have more responsive is not only a waste of time and money, but you'll find it won't really be what you're looking for, you'll basically be restricting it with such a small rear housing and have fairly erratic power output

a garrett gt3071r or gt3076r 0.82 will both be much better suited to an rb25, in regards to power and response as a package... you won't be dissapointed

the new Garrett GTX3071r 0.82 (the 5 bolt rear garrett design, not modified copies) with correct supporting mods will see power figures of 270-300rwkw on 98ron and response of fullbost (17-19psi) by around 3600-3700rpm ... with slight modifications to the standard heatshields it can be installed to look fairly standard too!... as opposed to your externally gated 3540 which wouldn't look so standard

food for thought

[kspots08]

Thanks heaps guys for your input. Definitely has given me something to think about. And yes Ruffels i do want the engine bay to look somewhat standard as the cops don't really appreciate if a external gate is right there in their face.

A mate with a 3540 went there, Stao have re-configured the front wheel and engineered that into a set of stock R34 turbo housings. It was heaps more responsive after its done, and looks completely stock from out side. from memory it costed just over $400.

[R31Nismoid]

That sounds like an even worse option.

I mean you cannot "reconfigure" a wheel. It's either you change it to another one or you don't.

So it wouldn't be a GT35/700hp comp wheel any more for a start, and if it still is - its TOO BIG for those housings as already stated.

Buy a turbo correctly, once. Be happy forever

[GeorgesR34]

Sorry I meant changed to a smaller 76mm comp wheel.

[R31Nismoid]

Easier just to sell the turbo and guy a proper Garrett designed one, with proper -IW housings etc etc.

3071 is what this guy needs by the sounds of it. Winner turbo.
