are you saying that i cant get a bridge port on my stock 86 6port motor?

I think you can do anything you want, last I checked anyways.... Theres usually consequences to our actions though. I don't suggest bridge porting an 6 port, or any motor for that matter, just because I don't personally like the consequences. You're welcome to bridge port it if you like.

im gonna get a cheap j-spec, and bridge it myself,

just a fun engine, for fun

it's just an issue of reliability and longevity for me.

You cant go big if you could Bridge a 6 port..I personally think its a shitty set up..



@ mazdaspeed7 how much for the template..and do you have pics etc..?

rotary7s@tampabay.rr.com

$25 shipped for the intake. I dont have any pics of the templates b/c my master set doesnt exactly photograph well. I use plexiglass for my templates, but any of them I sell will be scribed into aluminum like the mazdatrix ones.



The port itself is about as large as you can go without compromising the casting around the port, and without dropping the corner seal. Judge Ito has complimented me on my port jobs before. Thats gotta be worth something.



If you want some pics, talk to me on AIM, af24179 is my sn

im kinda in that mood to pick up a 1st gen and bp the mother fucker

ChainSawOnSteroids 11-15-2002 10:22 AM

im not concerned with reliability as it will be n/a so i dont care, also it will just be a fun motor, so if it blows ill replace it with the reliable one, and do it all over again, lol its all in good fun, maybe a peripheral port? who knows

Turbo II 11-16-2002 01:06 AM

a pp would not be that reliabile to drive on the street same goes for a bp. i would drive a bp on the street though cause i wouldnt stop smiling. and smiling is a hard thing for me to do

mazdaspeed7 11-16-2002 01:25 PM

Why isnt a PP reliable on the street? They dont have the side seal wear problems of a BP. The PP itself doesnt cause much wear on the apex seals, look at the stock exhaust port, its peripheral. And the higher rpm's dont induce that much extra wear.

ChainSawOnSteroids 11-16-2002 04:06 PM

hmmm thats something i never thought about(reliability on a pp) but keep in mind that a PP wont idle anything less than 2k rpm's which is unsuitable on the street (i dont care hahaha) so im getting a PP (once i finish my current project)
