so this is what ive been playing with for a little while, ex-pro7 car, thats getting a 12a PP engine.



just got the wheels yesterday, so now it looks cool

You've got a lot of junk in your trunk, mister! https://www.nopistons.com/forums/pub...1047683607.gif

yeah, the water heater broke, and we had to clean out the garage!

I like!

That is pretty sweet.



So let me get this straight. To P-Port you basically just drill a big-ass hole in the rotor housing and fill in the original ports, and put some sort of "runner" in said new big-ass hole so you can bolt an intake to it. What needs to be done for cooling?

damn that thing is beautiful. i can never find clean 1st gens around here cheaper than 5k...



those wheels are sick too. nice ride...

Is that a 12A or a 13B? Looks like 13B waterpump/front cover, but the housings look too narrow in the picture for a 13B. How ya gonna mount that puppy?

thats the cleanest way ive seen.

engines a 12a, its just mocked up. of all things i need to find a 12a front cover and oil pan! i used to have em....



i'm hoping to use the aluminum water pump housing, but we'll see

There's an extra stud for the 13B waterpump, and I believe the front cover has more dish for clearance of the aluminum pump housing. The aluminum is about 5 pounds lighter, tho, if not more (going off memory... its fuzzy).



If you got a 13B center iron and did a FC subframe swap it'd be perfect, tho! lol

bad peepers, no!

bad peepers, no!

What webber are you planning to use???????

that one!



efi is in the works too

Are those your X plates? I've never seen an intermediate quite like that before.

yep, i'll go grab some more pics

x castings.... these are factory filled ports. comp stat gears

Intermediate looks similar to the JDM 12A setup.

Thanks for posting pics! The intermediate has the upper machined section of a '76 or newer but with the temp sender hole os a '75 or older. Also tall ports of '76 or newer, and with an ACV port. Was it filled in?

acv in the iron isnt filled, but the rotor housing has no port for it, so its blocked there.



i should take pics of the rotor housings too, big font MAZDA housings, but the exhaust is sleeveless and differently timed

Do the exhaust ports open later than US-spec, like MFR housings?

yes. i printed out a degree wheel, and its got mfr port timing, which when coupled with the carb, is going to be nasty

where the hell are the port pics?

ahh this thread is useless without port pics!

way laggin on pics, engine is in the car, this pic is a couple days before it went in

what is this crap, where are the port pics?

its just a hole.... actually i should do one, if you shine a flashlight in the trailing plug hole you can see it thru the intake port

damn it, you put it together and took no pics of the ports?

The intakes are probably the same as MFR timing, right?



Hey are you going to use the water temp hole for a guage?

yeah i did put a degree wheel on it, port timing is close to mfr timing.



i think i'm going to block off the hole, but i do have that sensor from an rx2, so i dunno yet

damn mike, that looks like its gonna be soo fun when you turn it on!

You could make an aluminum plate and install an aftermarket sender.
