My take on this, I had an 01 gt with a kb on it in the past, the little kb for the 2v cars is the 2.1 this blower is designed to be used on a stock motor, it does not perform well on a built motor and no way will make 600hp period, you would have to go with a 2.6 then you would need a hood, and a whole list of other things, and this again is made for a built motor, and really should be done as one package all together, and trust me it will cost you plenty. If you are looking to get a blower right now on a stock bottom end and then upgrade as time goes on get the vortech t-trim or the novi as stated...ya kb is awsome for down low tourqe and instant boost, but I been in vortech cars and they are just as awsome, and dont worry about taping the oil pan its nothing, and in fact I think a lot easier then dealing with changing blower oil, trust me its a pain the butt big time, check out keenebell.net, and also mph and then go from there, search the threads, but unless u want to put down prob over 15 or more on the 2.6 and a built motor your best bet is to build your way up with the vortech or novi, thats what I would do if I did it again, I got rid of my 2v though for a cobra, I mean look at the 05 and up cars keenebell makes a 2.6 that fits these cars as a kit and can be upgraded through time with more boost forged internals etc, but as far as the 2v cars go 99-04 its just not worth going with a kb unless u got tons of money to burn, or you are satisifed with the little 2.1....my take on this
