Ive been studying Judge ITO's porting threads and learning from some local roto heads that have been doing this for 30 years.

I started today with one of my bad housings- Praticing on the exhaust ports. All I did was remove the material to the stock outline, and then add back the 2mm bevil that surrounds the port. Remember first time here and im working with nothing but a dremal and some carbide bits.
I know its not perfect, I also know that I lopsided the port edges, ones not quite stock shape. But eh' for a first try, its not that bad IMO.

 

Little too big?

 

Front plate....

and what do you guys think about this for the intermediate ports?

 

looks pretty clean to me.

 

not bad... where in Oregon are you.... near eugene?

 

Im 20 minutes south of portland .

But my gf's grandparents are down in eugene. I think I will be there next weekend infact....

 

did you check your ports with a plexi glass with rotor spinning on the plates? watch out your side seals and corner seals........

 

Damn, can't find anyone in eugene that is rx7 inclined. I down here all by myself. Noone to tune or build or mod with...

 

Lmk if you want help, im always bored out out of my mind. lol

 

So heres today work. I cleaned up all the ports and praticed on my exhaust ports some more.
Let me know what you think.

 

More... I think I like this method for my exhaust ports....

 

er that housing how bad is the mark/ gash in the center... looks nasty... on your primaries> I would slant the top more... more like 88integrals find some of his ports and you'll see....good for side seal. maybe aliitle on secondaries also... bevel/hand ssand the edges alot//some nice fine grit

 

These are all spare housings I am praticing on .
Next ports will have a more agressive edge.

 

Bump for more input mabey?

 

make sure you do that!

 

Really good for first time. Not bad work at all. By the way... I am in Grants Pass Oregon until the 22nd !

 

grants pass huh.. about 100 miles... erso from eugene... what ya doing overthere...

 

Ah why are you in grants pass BDC?

And I will check the sides seals and stuff with a plexi rotor, thankfully I have about... 10ft of plexi laying around.

Cant wait to get this motor together.

 

love to help ya slap it together but damn the drive...damn gas prices..... plexi rocks..... I've got 4 ports on one piece

 

Very nice for a first port job!

Makes sure that you shape the top of your intake ports a bit more,especially the secondary ones.

Well done!
