All Garrett Part numbers are 4 digits.g_man1968 said:GT30R
a GT3071R would spool a little faster but it has an internal gate which I do not think is a good thing at those h.p. levels. You could weld it shut and go external though. For 200 rpms, I would just get the GT30R.
Pete, you are stuck between a rock and a hard place with this goal. Assuming race gas, race tune, and the mods to allow and support that kind of airflow, you have these posibilities...and they all sacrifice some low end power and response.Pete said:Hi guys, I really need your expert opinion here. I would like to upgrade my turbo, I'm looking for around 350-400rwhp, low to mid boost 24psi max, and fastest response.
Which variation of the Garrett GT series should i look at and what size?
GT30R = GT3076R. They changed the name but not the turbo. Just like the GT28RS is now the GT2860RSMISTER2 said:All Garrett Part numbers are 4 digits.
I have a GT3076R, there is no such thing as a GT30R. GT30R is just a commonly used name for a series of Garrett Turbo's.
The GT30 refers to the frame size of the turbine wheel inducer.
The 76 refers to the exducer diameter of the compressor wheel.
The R refers to it being a ball-bearing turbo.
See the links in the 2nd post in the Big Turbo Sticky at the top of the forum.
elmo owen said:GT30/40 would be my choice,i have similar goals and that the unit i chose,that way you dont have to run everything flat out,reducing wear like you would a GT28.
I have a GT35R from full-race, that i bought from a member here on the board. GT35R, does it need 4 digits? There are some that are 4 digits, and some just two.MISTER2 said:
