Hi, I’m planning on doing some exhaust porting on a turbo 13b which I will be using for drag racing and I was wandering if any of you would like to post up some pictures of your exhaust ports to help me, also if you could do it again what would you do different this time.



Cheers

This customer made some big boost at really low rpm until he blew up the turbo. I guess he needed more turbo https://www.nopistons.com/forums/pub...#>/biggrin.gif

How much boost, at what RPM and what turbine/housing?

I spy an RX-8 E-Shaft and other lightweight goodies.

Damn, I haven’t had a chance to look at this yet, if anybody else has got any pictures pleas post them. https://www.nopistons.com/forums/pub...DIR#>/wink.gif

Ok this is what i want to do what do you think.

one more.

Here's the racing beat race exhaust port for a 12a. The 13b RB template will be pretty much the same but of course wider. I just finished today. I still need to polish up a bit more.

Why so round? Square is good like that racing beat 12a port picture

I don’t know that square port looks kinder frightening https://www.nopistons.com/forums/pub...R#>/unsure.gif
