Default School Project Help

I have a project I have to do for my autos class and I need some help. We have to buy a car, and modify it to run the fastest time possible at Grattan Raceway. We have a $25,000 budget which includes the car, all modifications, labor, fluids, and services. I was thinking of getting a 2002 WRX. They're running for around $5000. What modifications should I get in order to get the fastest possible lap time? Should i get a different car? We will test out engines on a simulator program. I also need to properly estimate HP, top speed, and gear ratios which i will do when i'm done. We will also have to run the same car in a quarter mile drag race with the same setup as for the raceway. I mainly need help on which car to choose and the modifications for it. We're not actually doing it; its just a project. Thanks

Here's a linke to the WRX i'm thinking about. It has a few mods on it

I would not go with a WRX for a pure drag car.

With a 25k budget, there are many better options out there.

If building just for a fast car, I would get something like an old fox body mustang, gut the interior, gear it right, and cram the biggest most built engine I could into it. The old dodge darts make great drag cars too if you convert them to a big block.

I agree that AWD isn't as good for drags but i think a WRX would be a great car for Grattan

Miata. Swap in an LSx Corvette V8 (they're aluminum and light). Konis and humungously stiff springs. 13" x 10 wheels with cantilever slicks. Strip the crap out of the car to get the weight way down. Make heavy stuff like the battery easily moved. Take it out of the trunk when your road course run is done. Put it up on top of the roll bar. Swap the front tires for skinnys and rears for drag slicks. For drags, you want lots of weight transfer onto the rear tires and higher weight transfers more (think opposite of roadracing).

Is Grattan a road course track? I assumed it was a drag strip .. sorry if wrong.

But still, I would not choose any AWD car for any road course on pavement/asphalt. There is simply too much drive train power loss and added weight from the AWD system. I would stick with RWD on anything other than rally-style racing.
