BoostBoy, I am messing around with a CA now, can you believe it? I have this long term project, that is slowly coming to fruition. It's for my '81 210 ice racer. Why would I build a CA20E? There's no aftermarket support, virtually no one has ever made good power with one, then why? Because I thrive on making boat anchors fly!
I parted out a 67-K mile '84 S12 200SX. So, I got the H190 rearend, the CA20E, and the matching 5-speed. It will all go into the 210. Anyway, back to the CA. I couldn't find a single scrap of cyl. head flow data for the CA20 anywhere on the internet. I went to the teamnse.com [Pintara/Stanza] website, and all I read was how everyone wanted to dump their CA20E's. So, as usual, I'll have to go this alone. I have ported the head, back cut all eight valves, and did some flow testing on my cousin's Superflow 110 bench. What is really interesting, is that the exhaust ports flow as good as the intakes! That's very unusual. But it's also really good for forced induction applications. I bought a nice little 70 cubic inch, two-lobe roots style supercharger for this engine. No kit, no manifold, no drive components, just a universal blower. Make the rest yourself.
It was made by KF Industires, in CA. I've got the drive system made, and it uses an E16 timing belt and gears. I am currently having my Dad [nice to have a machinist in the family!] deck and O-ring the block. I will build the blower manifold out of 3/8ths" thick aluminum stock. On top of the blower will be a 44mm Mikini side draft carburetor. No ECU for this car. Like I said, this won't be done next week, it's a long term project, but I do plan to make this a reality!
