I'll agree with Dave that the .63 is where it's at for response but only with an external waste gate. A big one. For me though, I used to get so pissed off with being on boost at low revs and the party over at 5,800 or even 6,000rpm. For track work, not only do I have power out of the corners but I don't have to short shift. More importantly though it feels free reving from idle. By that I mean effortless driving at next to no throttle movement. But when I want it it is there with just a few more revs. Been driving to Kellyville from Campbelltown this week and getting 480km to a tank but been playing with the boost controller to so a couple of prods with the pedal as well. If I could make one choice I would buy the 3076 .82 as this is THE perfect combination in internal waste gate turbos. Only because I don't mind the lag. Something about an RB engine that still pulls strong at 7,000rpm, sounds delicious.

Interesting Gary , the only inbetween (3071R and 3076R) that I can think of is the 52 compressor trim version of Garretts real GT3076R/GT3037 . Brett at GCG reckons he can supply the real GT3076R in 52 comp trim and it uses the same port shrouded comp cover as the usual 56 comp trim GT3076R . I have not see the ones he has but he did say (before they arrived) that he was goung to put the IW GT30 turbine housings on them .

Just for the record the 52T 3076R should have the cartridge number 700177-6 , 56T is -7 .

Back in a sec .

Just had to check the turbo assembly numbers for Garrett/HKS , Garrett GT3076R 56T - 700382-12 , HKS GT3037 56T - 700382-11 , HKS GT3037S 52T - 10 .

On the HKS USA website they list:

HKS3037

- 2.75" inlet

- Rated at 420/440/470ps 48/52/56 Trims respectively.

HKS3037S

- 4" inlet

- Rated at 450/480ps 52/56 Trims respectively.

The 4" inlet apparently helps in the order of 10ps.

The 4" inlet ones have the ported shroud , the 2.75" ones are normal T04E 0.60 A/R .
