Im getting very close to having the extra money for my TS upgrade. As of now im leaning towards the KB 2.8H. At this time in my life I need to make sure I can keep the car daily driver capable and be able to run on 92 octane and am hoping to be able to achieve 550-600rwhp with this blower, which from my research seems very capable. The reason Im not going with a smaller blower is because in the future if I have the luxury of turning this into more of "just a toy" I would like a blower that gives me room to grow into. With that being said is there any KB 2.8H owners running it at around 600rwhp? How much boost did you need to attain this and how are its street manners? I dont have a CAI at this time and dont have an upgraded TB so not sure if the mammoth kit would be worth it for me since it comes with both. I was planning on going with 60lb/80lb injectors KB BAP and what Mass Air would you all recommend? Thanks.
