Hello, first of all, introduce myself to the forum, in the next few days I will assemble my miata turbo and I am undecided about which one to choose

I'm undecided between garret's gbc22-350 or pulsar gtx 2860 (.64 a/r)

I am also considering pulsar g25-550 although I think it is too much for the figures I am looking for

I have wiseco 87.5 and forged connecting rods so my goal is about 300hp and the main use is street/drift car so having a good spool would interest me


gbc is journal bearing the 2860 dbb (I think this would compensate for part of the delay although I'm not sure that's why I'm asking for opinions

I don't mind not having the water cooling since I respect the times of use

 

I have a 1.6 with a gt2560 and for me it very slow to spool . I see real power after 3800rpm 2860 is even bigger....

 

Good spool, great power and 1.6 isn't easy. Are you using E85?
Maybe limit the power goal to 250hp, if response is important. 2554R, GBC 20 or 22, nothing bigger than 45mm inducer
