. first off a zetec with the same turbo kit as the spi has would have maybe 20 more horsepower and 20 less torque than the spi, just remember horsepower sells cars torque wins races. and that knocking you hear has absolutely nothing to do with it being an spi so go do your homework. if it was a valve seat it would sound nastier than that, the knocking is most likely from a poor tune. and i was being very conservative with my estimate spis can make damn respectable power with the stock motor boosted, if it didnt i wouldnt have even considered building mine. ". also how do you know how much money he has into it? ive got damn near everything ready to bolt on to turbo my spi and geussing from the top of my head im under a grand including a atx to ib5 swap . jeffescortlx made 212hp and 262 torque on a spi and that was on pump gas andwith the 1 7/8 exhaust with the 3 inch turbo back and e85 he was probably closer to 250-260 hp and 300 torque if you ask me in a car that started with 90whp thats a little better than some potential seeing as that was stock internals and cheap engine management.not meaning to sound like a dick but so many people are uneducated and just spout off about the little spi without having any understanding of it. they have one major problem valve seats which can be remedied cheaply then the spi would be just as reliable as a zetec
