Was hoping you guys might be able to provide some insight. I have the JWT 530 kit and am running it on a stock block with the JWT SS box. Car runs great and makes 370 rwhp. A solid tune with no problems.

So, like everyone on here...I have the boost bug and want to turn up the boost. Not that much given the stock block....in it's current form the kit boosts ~ 7 PSI (I have a gauge) at right around an 11.5 AFR. I wanted to raise the boost to 9 psi while mainataining the relaibility and am a little worried about the stock injectors already being at the end of their duty cycle..although I've heard of numerous cars with the stock injectors running around 400 rwhp. My goal is 400 rwhp and was thinking of upgrading to the VK56 injectors. After which I would get a retune and the HKS manual boost controller. Given such a low boost application it may just be a waste of money to go with an EVC 6.

Has anyone upgraded to the VK injectors with a JWT kit? are they a direct plug and play? Anyone bump up the boost past the preset wastegate setting?

Thanks for the insight....

 

just get after market one like DW, and stay under 600cc. I ran my stock block up to 11lbs daily. took it apart and it was flawless

 

How did you bump the boost?
