For the sake of this thread you can also get to 300RWHP without adding boost by changing the turbo, intercooler, and adding a set of SC or like cams.

For 400RWHP using CIS:
- Port Heads
- Headers
- K27S
- iA Fuel Head Mod
- Adjustable WUR
- Larger Intercooler
- 1.0bar Boost
- Free Flowing Muffler

Hmmm that's good to know! I didn't think you could touch 400rwhp using the CIS. I think my next upgrade is a better and bigger intercooler. What is the best bang for the buck there?

My car has a guesstimated 340-350 rwhp. I am nervous about running that 1 bar spring.... I usually don't push my luck with the throttle pinned too long
