On the highway my brother with a V6 Mustang 3.8L(200hp) raced a Twin Turbo Supra his friend(about 300-400 hp). Now at this time my brother has enough money to buy any mod up to $3,500 what would you suggest so he can kick his *** next time.

 

Lol Nothing to do with camaros lol. Prolly Nitrous or a turbo. It's very hard to get the same power to weight ratio as a supra.
Cold Air intake
recalibrated MASF
Catback
headers
underdrive pullies

 

I know what I can do to my car plus im not old enough to drive so no point in wondering even if I have the money.

 

I'm sorry, I was just responding to the post.

 

Sorry if I came off rude but I meant to cause no trouble.
