whp or hp?
maybe 220whp is the max with the stock turbo but I'm not a 1.8t expert but lucky for you there are some here!!!
I guess it is possible to get somewhere close to or slightly over 300whp on the K03 if your spraying. A nice 75 shot w/ a bigger fuel pump would probably get you there pretty easily if you have a 1.8T with all the colt on parts that are common. The K03 shines when it comes to tq numbers though.
If you really want the ability to go above 200whp, I would just start with an upgraded kit. Talk to ATP, you could start with their stage II kit, and continue to upgrade from there. You could get the Stage II kit w/ a different turbo (50 trim t3/t4) and 440cc injectors, and run it on the stage II software for a while until you have more money to buy parts like a FMIC, fuel pump, etc. It would run fine like that. To begin with, you would have around 220hp, but you could easily tune it to well over 300 once you have a chance to buy other supportive mods and get it tuned on a dyno.
Billy T was using a T3/T4 - it was a 57 trim T04E compressor in a 50 trim housing and
I beleive a stage 3 .63 turbine. He handled fueling with a Greddy Rebic 4, and boost pressure just short of the factory fuel cut using a Profec B.
He used multiple bleeder valves to override and fool the ECU into thinking it was below the fuelcut/limp mode. This was before people figured out to clamp the MAP signal to the ecu to accomplish the same thing. He was running much higher than factory fuel cut boost pressures to get those numbers. He also had the intake manifold drilled and tapped for secondary injectors, that is why he needed the Rebic.
