Ok I want to rebuild my S5 N/A motor and want to port it myself...what port would you recommend to make large amounts of power? Someone suggested a BP

I want at least a 13 second car! N/A!

 

big street port. the other ports are not really stuff you could do yourself unless you changed other stuff as well. like ecu change or carb setup. basic street port info for 6port NA's here: http://www.mazdatrix.com/engsp6p.htm

some bp stuff as well from their site: http://www.mazdatrix.com/faq/portbp.htm

also for exhaust porting you probably wanna use Turbo housings.

I've seen 13 second (LOW 13 second) 1st gens with just a Bridge ported motor. THey are SILLY fast, lol

Get your self a BP, and either spend 1000$ for a computer system, OR get your self a nice carb set-up, and you'll run 13's

"Warning. Get use to a 12-1500 idle and terrible gas miliage. But hell, i guess it's the price to pay for a 13 second car right"
