What else should i do with my stage 2 streetport. I hear theres not much gain using just a streetport engine. I was told new muffler, mines sitll stock, and a cone style K&N, but anyhtign else that i should do to maximise streetport perfoamnce

Oh yea, my engine is a 13b 6port from an 84 -se

This is my opinion: Use early RX-7 12-A plates to convert that GSL-SE motor to a 4port. pin the rotors so you can rev it past 9000 RPM, 3 window bearings, high pressure OP regulator and port it as big as you can go. And use 48 IDA. I dont know what your driving habit is but since I drag often, I prefer a heavier flywheel and puck clutch/heavy pressure plate. Thats my $0.02.

Mazdatrix has a good writeup on street porting 6 ports or actually why not to port a 6 port-you should read it unless youve already. http://www.mazdatrix.com/faq/port6p.htm
It changed my mind about it, I'll look for a 4 port or go with a more readily available 12a (looks like a far better gain)

Are you keeping it efi?

Well im buying a remanufactured streetport, and for the core i gotta use the same motor as i buy. Im not looking for the fastest car every or anything. Im sure a 6 port will give me enough power. Im just wondering what other, non major mods should accompany it

BigJim

yea its stayin efi

wwilliam54

id carb it

if you insiste on efi, get a 2nd gen dynamic chamber

BigJim

Well maybe down the line once i pay off the engine and port ill get one. After this, im leavbing it alone until i get some of it paid off
