So guys I'm needing opinions on a matter including a turbo. So my friend got his car wrecked the other day and he had a 99 si with a b16 engine. He had that car turboed and he ended up selling me the complete kit for 800. The kit consisted of a top mount manifold, custom b16 piping, tial wastegate and blow off valve, 3" dump tube, a manual boost controller and what he said is a gt40 precision turbo. I have been reading a good amount of information over turbos lately since I've been wanting to turbo my ls.

The question I have is I know the gt40 is a huge turbo it has a. 83 ar on the compressor side which will take all day to spool, would you guys recommend me putting this turbo on a bone stock ls(already checked compression and did a leak down everything was fine) or would anyone want to trade me a smaller one like maybe a gt28 or gt30

It is a large turbo for a non vtec motor to spool. That being said it will have a lot of lag. You will not be able to run enough boost on a stock engine to be efficent, but on the good side you will not have to run a ton of boost to make the same power as you would on a smaller turbo. I have a SC61 that is simillar to the GT35 if you want to trade but that is also a little on the large side. But thats up to you

A gt40 on a Honda is retarded unless your aiming for like 900+hp. Its even dumber on a b16 in which that thing would've never spooled on lol. A 50 trim is not a bad option on a LS, a gt30r would be a nice tubo as well. Its all about Budget, Hp goals and what type of driving you do with the car
