basic turbo question..trim? internat gate? help

[Ltrain]

what t3/t4 turbo trim would have the less lag. Im assuming the smaller the trim the quicker spooling the turbo?
(rather have t3/t4 for better top end, dont want a t3)

what do yall think of the above turbo?

and if a turbo has an "internal gate"...do they mean wastegate? so im assuming i wont have to buy the wastgate?

sorry if there dum questions

seems you have a gsr, i think that turbo is too small for your application. i would go with at least a 50 trim but you have the right idea, a smaller trim spools quicker but cant make as much top end power.

and the internal gates have a built in wastgate flapper but require an additinal wastegate actuator arm.

what are your power goals?

i would say go with a larger trim. my gt28r spools at 2500 rpm. very quick spool and lasts throughout the whole rpm range.

gt (ball bearing turbos) are great as far as durability. they will always cost more. sp is where i got my manifold. great company. thats a pretty good price for a new turbo. mine cost 950 new.

hmmm gt28r have the same top end power like a t3/t4?
