Dont get ITB's if you daily it.. will be un streetable gas mileage wise lol. And expensive..

Just get a K&N Intake + the racing beat exhaust if you can afford it... pretty pricey but it does have a good gain and sounds awesome.

Rather that or do a custom cheaper exhaust (2.5 inch max) .. keep cat in if you want more low end, strait pipe if you want more top end power. high flow cat for 1/2 and 1/2 Its good to have a bit of backpressure on a N/A RX7

If you want your motor to last , do the following..

-change the oil every 3,000kms
-never overheat
-premix the gas with 2 stroke (tcw 3 2 stroke from chevron)
-Redline the car daily
-use 87 octane
