ls turbo 50 trim question??????
Okay guys I've been on the fi thread for quite awhile. Reading about different setups and what not.I currently have a jdm b18b motor with a usdm b16 tranny. Along with a turbonetics turbo kit( I got the turbonetics kit for dirt cheap
).The turbo on the turbonetics kit is a t3/t4 50trim with a .48 ar rear housing.I have been reading and looking how much those ls-t have been putting down.And I see that alot of them put around 250hp on there 57trim setups on around 8-10 psi.Now I know that my 50 trim can't put that on 10psi.But can I upper the boost to reach 250hp on my jdm b18 safely on my stock motor.And if I can how much psi can I go before the turbo max's out.Sorry for sounding a little noobish but I'am very curious.Help please oh and thanks in advance Joe.

Power is what breaks parts, not PSI. If you run a smaller turbo, you're going to have to run more boost to get the same power as a bigger turbo. If you need to run 12-14psi to hit the power goal you have, then that's what you'll have to do. The only thing is, for a stock LS block, i wouldnt go over 300whp...

The 50 trim is more suited for higher boost but it will still produce good power at low boost. It will need 10-12 psi to make the hp you are looking for and that also depends on your tunning and the rest of your set up.
I hope this answers your question.

great,okay so I understand that. But I still don't really understand that much about turbo effic.. So you're saying that I can raise the boost till I reach my goal of 250hp.But like how will I know if my turbo is maxxed out???????? That's really the only thing I don't understand.So I can use a manual boost controller .Upper the boost to what I want it on.Then have it tuned to how much horsepower I please???

He's right, but if you really want to know, you can learn how to read compressor maps. The general rule for most T3/T04 turbos (standard journal bearing) is that you should keep them under about 23-24psi. After that the majority of them begin to just move hot air with little power gain. This isnt something you'll need to worry about...
