Dual Port Heads for EA-81?


Recommended Posts

When you say turbo heads, I'm thinking that you are refering to the EA82 turbo heads, the EA81T's have a single intake port like the NA's. Then SUB4 heads are REALLY REALLY spendy, I looked into those also. What you could do, if you are pretty good at welding aluminum, is drill out ports into the "bubbles" in the head, the block off the single one, then make up a flange and weld it to the new holes in the head, then make up an intake to match, would be interesting to see, also would be pretty interesting getting to the spark plug. You'd also have to make up something to run the water lines for the thermo houseing and heater and the crossover.

Consider this:

 

Look up the RAM Performance Webpage, they have tons of EA81 airplane stuff...the guy sells kits for springs, lifters, valves etc...Order the relatively cheap spring/valve kit, that has the wider bore, then take the heads into a machine shaop, and have them bore the single port holes to match the valves...that will definatly give you a substantial gain W/o all the cost...
