He has the VG30 rear housing

which means it'll probably be a 56mm cropped turbine wheel, which means a proper gt30 turbine housing wont work

[Simon-S14]

what sort of power is it making now? 270-280 seems to be the max for these types of set up's regardless of if its a 3071 or 76, the rear housing and wheel spec just cant flow much more then that.

[neo32]

just feels real choked up top

what housing u rekon dan

[neo32]

the other big issue i have is boost controll ie none

it just gets out of hand and the wastegate cant bleed off enough air and the boost keeps rising

[Simon-S14]

how much boost, and what dump

[discopotato03]

The details off the turbos ID tag would help identify its turbine . AFAIK the GT3076R's were never made with the cropped or 56mm GT30 turbine .

Does it have a port shrouded compressor housing , usually the dead give away for a GT3076R/GT3037S .

Most , but not all , seem to like the genuine Garrett GT30 IW turbine housing in 0.82 A/R . Std the Neo had a larger turbine housing than the R33 GTS25T's and different cam profiles and VCT . In theory same bottom end and more top end from better breathing and a bit less exhaust housing restriction . I think the numbers were 184 Kw vs 209 for R33 and R34 RB25DET's .

go cut 4mm off your turbine and leave it in the same housing, see how it goes.

find out exactly what cartridge you have then find a housing to suit. you cant use a gt30 housing designed for a gt30 turbine if you have a cropped 56mm turbine.

Garrett I/w GT30's have the 56mm turbine. Only the External gate GT30's have the 60.3mm rear fan

[JonnoHR31]

only the bastardised ones with "bolt on" rear housings have cropped turbines. the proper gt30s with a proper IW housing have the 60mm turbine

Not according to GCG

they're still the 60mm turbines, they have the exducer diameter listed instead of the overall diameter. they have the same 55mm exducer size listed for all their gt30 housings
