Well I mostly read on here, but I figured I would finally contribute something. These are my ports I am doing for another fellow in OKC. They are FD plates. We are hoping to see 400+ hp. I will be redoing the primaires to the same size. The reason being that I broke into the water jacket on the other side. Its a pin hole sized hole. I will repair it and keep the iron for myself. I don't feel comfortable w/ a repaired iron in someone else's car.
Any constructive crizicism is welcomed. I have ported several motors, we can always learn more. Thanks. |
They look really good from what I can see. Those pics aren't the greatest. Did you use templates?
Also what are your plans for the exh. ports? |
I suck at taking pics. I didn't use a template. I like to feel the ports for the first ones I do. It depends on the motors use. Then I make a paper template from the original and copy it to the other side.
I will post some pics of the exhausts later when I finish them In the mean time here are some pics of the exhaust from another FD I did. This picture is before I bevelled the edge around the exhaust port. The primaries on this motor were mild and the secondaries were a little smaller than the ones above. |
Your exh. ports look pretty much the same as what I use. I go a little bigger than a rb race port. Looks good. Nice job. Not sure what you mean by feel the ports though. Whatever works right?

your ports look very good.
for help with making templates you can always use plexiglas to visualize as opposed to just feeling. i know it doesn't help with depth, but it will be better than estimating. |
Oh wow man that is really nice looking. I wish I could trust myself to do that https://www.nopistons.com/forums/pub...O_DIR#>/11.gif

all you need is a steady hand, a little knowledge of port timing and seal tracks, and some carbide burrs. And know bigger isnt always better https://www.nopistons.com/forums/pub...DIR#>/wink.png See that is part of the problem I am REALLY new to rotaries and plan on using a decent sized turbo for the TII swap I am going to use through december. So exhaust ports should help with spooling the turbo quicker.(There may be alot of bull **** in that last statement, feel free to correct me if I am wrong) Not to mention I am 19 IT guy...I drink ALOT of caffeine and have since I was like 5. A steady hand is not something I have. I found it hard enough to cut a washer of my crankshaft pulley bolt on my honda. |
Just dont expect your first time to be the best work. I love caffeine as well. About 7 Dr.Peppers a days worth. You need to understand where the seals travel and where you can port. Look at some used irons and it will give you a great idea of things.
Bigger is better 95% of the time in my book. I run a 88 N/A with amost the identical port on the primaries as what is posted above. I also run that motor w/ larger 5th and 6th ports w/ no sleeves and a large exhaust port. The car has a straight pipe (no cats) and stock intake. It doesn't have much power under 2K but it really screams above 4K. Everyone has a slightly different opinion. The one we agree on is the stock ports are restrictive. |
shitty looking ports. I dont expect that engine to last 2000 miles.
