Sorry Im sure this is a stupid question, but what is the difference between these turbos? I know one is made by garrett and the other by precision but my question is, if I get a bigger t3/t4e, will be essentially the same?

PS. My goal is 400whp and i dont mind a late spool.

 

"T3/T4" describes about 80% of the aftermarket turbos out there. A SC61 is a T3/T4 too. You need to compare wheel sizes.

 

okay sc61: 56 trim and .63 a/r vs. garrett 57 trim .63 ar

 

Are the wheels designed different too?

 

Hehe I'm not trying to give you a hard time but not even trim is going to help. Trim is merely a the ratio between the inducer and exducer of the wheel. A small T3/T4 can have the same trim [ratio] as a large T3/T4.

 

So why is the sc61 so much better? I'm just asking for differences because I can't find anything searching.

 

Since this thread seems to be going in the "post your noob questions here", why are some turbos "60 trim", and another one is "P trim"? Where did someone get the idea to name something after a letter vs. a standard number?
