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

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...

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?

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

Chris Taylor 06-12-2008 10:24 PM

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
