Anyone Using Hks Gt2835 48 Or 52t Turbos ?

[discopotato03]

Hi all , I'm trying to find the turbo cartridge numbers for these turbos which is hard because not to many seem to use them . I was wondering if anyone has them and can check the ID tag for the numbers .

I want to look into using one of these in a 0.68 A/R GT Pro S IW turbine housing for my R33 .

Cheers A .

Do you have the housing? If so good find.

Everything I see in the Garrett master sheet with the cropped 56.5mm version of a 3071 ~ 2835 is shown with a 56T compressor. Not to say they don't do a 48 or 52T but you might have more luck finding rocking horse sh_t.

As a side issue, you know my 48T 2871 hybrid makes 300 rwhp. Garrett rate the real thing ~ 380 odd hp, and working on Sydneykid's drivetrain loss of approximately 80hp it's within spitting distance of getting there. So basically those OEM housings haven't really held it back. If for some reason you spec'd a 48T version then there might be no net gain.

I would concede the potential extra efficiency of a HKS housing might make the engine breathe easier up top, but there's not a lot of extra to be had. I acquired an OP6 housing (A/R ~ 0.7x) to try the theory, but it's currently sitting untouched in the shed. After a few calculations I concluded that I would have needed the extra capacity of a 52T or 56T to make the whole effort worthwhile. And then I'd have a whole new hybrid.

Hopefully someone can confirm or reject whether you could get an off the shelf cartridge, or have to get a custom one built up.

Off-track, but I'd hoped you'd go down the route of the split pulse. At least it would put a certainty to all the discussion in that area.
