Exhaust port spacing question (fabricating manifold)
 

Hers the question, on my Tercel engine (3E) the exhaust ports are rectangular and really clost together. I was going to try to make a log for it but wanted to know if it was alright if the "runners" for each side were just one bigger peice of pipr that covered both ports, or if that would cause issues..

If you can immagine the ports are like [][] - - [][],

I think they would distort each other

I think what he meant is can he use one large tube for 2 ports.

that is what i thought he was asking and yes and he can, of course the flow wont be as good, but its a log for crying out loud. Its going to be relying on back pressure anyways so go for it.

two things are for certain in this world... Hotrex is gay, and so are logs. Spend the extra couple hours just making it into a HF style manifold. Think of it like this, your getting free horsepower and spool up time over a log for just a few hours of your time....?
