I'm thinking about turning my old daily into a beater track day car for a 'lemons' style event (though with shorter race distances of no more than 1 hour), much like the guy in the other thread. Rules are that it has to pretty much be as stock as possible. Also, I want to put as little into this car as possible, and don't expect it to last more than a round or two. Aside from making sure the brakes and tyres are decent, what else should I look to modify on the car? I've heard people say I'd neet to add an intercooler for the CVT, but is that really necessary? Has anyone tracked their Fit?

 

Unless you starve it of oil, you wont be able to kill it lol

 

I suggest Swift Springs and a Progress Rear Sway Bar.
As for temperature concerns, mine does get hot but I haven't installed my Mishimoto radiator yet along with a new Spoon thermostat and switch.

 

No idea about the CVT, I can't imagine it's great for tracking but use what you've got!

I didn't end up racing it because some events got canceled and moved due to covid, but in terms of bang/buck ratio, my plan was

• Remove everything from the interior that's not mandated, i.e. seats, carpets, sound deadenng, spare, etc. This is free!
• Grippiest tires possible. I run Nankang NS2-Rs on my miata and they are pretty ridiculous at a reasonable price. Plus theyr'e available in small sizes, I have 195/50R15s which should be ok for the Fit as well.
• Sway bar and other suspensio mods
• Boost!

I was thinking of the classic ebay turbo setup, until I found this cutie. It's a supercharger the size of the AC compressor!

For a low cost/effort build, I think the huge advantage over the turbo kit would be that you won't have to touch the hot side at all and thus save a ton of fabrication work. I didn't seriously look into it, but I think it should be possible to mount it in place of the AC, route through an intercooler and directly into the intake. The trouble as always would be with the ECU, still.

 

Intercoolers are for turbo applications. Not for a CVT trans.

The CVT trans works by slippage. So It's not ideal for racing like a manual trans would be. Also the CVT trans doesn't like heat. So racing one may not be the smartest plan for the cars longevity. Nor would it last many laps at full speed compared to a manual car.
