You're not going to make 350whp on an 18g....unless you use e85.
The last 18gxtr I did on a 2.5L made 275whp
You're not going to put on a smaller turbo and make more power than you are now. You need a bigger turbo to hit 350 on the road dyno, or e85. Even with meth you may not do it. Maybe if you use an aquamist kit with dual nozzles.
If you guys are wanting to use small turbos to make big numbers you need an Omni 3 bar MAP sensor to be able to run higher boost than 20-21psi. you need at least a 70mm intake. and you need e85 or meth. And when you start push high boost, then a fmic is a good idea too. if you utilize e85....you'll need injectors
