I was wondering if this turbo would lagg on a LS motor with stock internals. Its a Garrett t3t04e 60 trim .82 AR compressor. IF it does should i go with a lower trim?

 

go with the .63A/R over the .82 for sure, and I think you mean the turbine and not the compressor (I'm pretty sure they dont make that A/R size that I know of for compressors). You could probably even go smaller depending on what you are looking for outta your setup. Alot of LS guys have had pretty good luck with the 57 trim. If you're serious about picking up a turbo sent Arturbo an IM and ask about Precision turbos.

 

Someone correct me if I am wrong but wont ALL turbo's lag some. Its just the degree to which they lag will vary by the size if it?
