Buy tomei arms turbo, ams intercooler, tomei titanium intercooler pipe, and oil line and fuel injectors. Also you would have to replace your transmission to heavy duty gears mrt performance.au has it Bret Middleton is a genius shoot him an email but he takes a long time to reply though. Your stock transmission can only handle up to 350 and still be reliable anything more and you will have to upgrade your transmission.

 

Im hoping to hit 380-420 with a MAP EF-3 setup with a Jacks transmissions 600hp fully built sst... anything over 310wtq on stock clutches will fry them. will let you know results when i get it on the dyno when the trans comes back from jacks. Keep in mind you need to have ALL supporting mods (Injectors, fuel pump, intake, exhaust, etc etc...) It takes a lot of modification to get there, but it works. if you want to switch to a twin scroll turbo you need to get an X exhaust manifold too. Also all the necessary hardware. Stock block should be able to take more hp then torque. My tuner suggests keep it safe and under 400wtq to keep reliability.

 

This is the exact thread I needed to read! I have a 2011 Ralliart and I am hoping to push 400HP as well with my car. This thread seems to have the right recipe to achieve what we want. I am on a budget as well but will be saving up for the transmission upgrade since that seems like it will be a must. Thanks for all the input guys, you have made it much easier for me to learn and put that knowledge toward my car. Build it right the first time!

Good luck getting an appointment there, I can't even get CBRD to email or call me back with a date to come in for a turbo install and tune......it's now been 3 weeks since I first contacted them and my phone calls and emails have been largely ignored. I was told that they were busy and would get back to me after 1 week, and haven't heard from them since. And this is not the first time that there's been a significant lack of communication in my dealings with them. Not happy with CBRD
