Whats up every one,
I'm sure there has to have been a post on here about this, but I am trying to build a new 08 scion xB. I want to get more out of the engine besides just what I would get from an intake and an exhaust. I want to build the car for track use and for shows. I'm thinking new cams, I don't want to do any forced induction, maybe a TRD supercharger eventually but for now I want to try and get the car to run in at least the 200hp area. Thanks guys. Once again, I know that you guys get this all the time.

ya i know. but i dont want that whole hassle of having to register out of state. haha, I'm just looking for simple mods. It's going to be a daily driver but i want to take it to the track on the weekends. so all i need is a little extra hp, and a damn good suspension

FI = forced induction (aka turbo and supercharger)

ya ya whatever. this is going to be the first car ive built for track. i have a jeep that i built from the ground up. I don't really care that much about it. I mean like I said I may go with a TRD supercharger eventually I just don't want to deal with overboost, and blowing up my engine. I already have a friend with a cracked block from his turbo over boosting.

The xB isn't exactly your most aero dynamic choice, but good luck with the build.

Well I hope to get into micro compact track racing. and I really don't think horsepower is THAT much of an issue as compared to grip

it has the same drag coefficient as the tc .32

A good start...

mild destroke + internals that improve Volumetric Efficiency + TRD S/C kit + cat_back exhaust + Ghetto Fab Intake - weight = legal xB

i figured on a carbon fiber hood for less weight, i want to keep the seats though. im going for a quicker xb, but with still the functionality, so i can still haul the girlfriend and the rugrats

I believe no 08 S/C has been announced (?) I was thinking aftermarket S/C then ... Turbo's is :no: bcause of catalyst removal

Carbon trunk & hood, yes! It's a sacrafice (!) of unnecessary items. Common suggestions- Use AAA instead of a jack, fix-a-flat, over a spare tire, lose 1 front (& 1 rear) wiper, manual steering, lighter battery, lose insulation/mats/sound deadener, speakers, lighter wheels.
