Does everyone use a template, which template did you use?
I'm having a hard time shelling out 60 bucks to mazdatrix for a damn bit of sheetmetal with a port scribed on it

 

I make my own...

how'd that work out for you? where'd you get the info for the sizing? Scan it and send it to me?

How is it running? did you notice gains? does it idle OK? Do you have a NA or turbo?

I'm rebuilding my 87 TII and want to port it as long as I'm there, the pricing on their templates just irks me.

Mostly for turbos...
NA's are a little more tricky to port, as you have more options in terms of port sizes.

I base the porting templates on my experience with working with these engines.

shieiiiit I'll be lucky if I can get this engine back together and make it run
gotta learn somehow I guess. Thanks for the input, I'm just afraid to go tearing into my housings with a grinder I guess.

 

60 bucks is worth the money....considering how much time and effort they have put into the design of the templates.....

 

bump. anyone else use other templates?

 

How much time and effort do you really think they put into the templates? They basically would have already known what size/location for porting would be good, so it's not very hard to cut it out of a piece of sheetmetal.

Sure, you know it's quality and will work excellent, but I can't see it requiring much time and effort to create.
$60 us is too much, but then again, that's Mazdatrix.

 

I kind of agree.
but, there doesn't seem to be any alternative

 

The alternative is looking at pictures of other people's streetports and making your own. Just don't port into the coolant passage.

 

that's great, but by the time you realize you've gone too far, it's too late.

 

The availble templates being sold are fine for most applications.
They are conservative to most of the "secret" porting shapes from most shops, but they will reward you with significant gains if you follow the instructions.

much better deal. mazdatrix wants like 60 bucks for the intake and another 20 for the exhaust.

 

also, from what i have hurd, mazdatrix's template is the RB template, Mazdatrix is just re-selling it
