After blowing my head gasket in Summer 2007 I figured it was time to upgrade the entire motor and went with a US EK (1751 CC) motor found in the first gen Preludes and First and Second gen Accords:
EK Engine Build - Spring 2008
Blown Head Gasket....Oops.
I got lucky and was able to find a fully rebuilt EK long block on Ebay. To my surprise, it was already bored 40 over.
Upon receiving the motor, I ditched the CVCC head with the intention of using my original EL Head. It needed a full rebuild so I contacted Bryan Maloof of Maloof Racing in Duluth, Georgia and had the head sent down to Bryan for him to work his magic.
Parts for any EL motor are very difficult to come by these days and through some very generous people, I had parts sent from New Jersey, Oregon and California to complete the build.
The work consisted of: new bronze guides, custom oversized stainless steel intake and exhaust valves, new Crower springs, Ferrea titanium retainers and Mitusbishi valve locks. The valves were made to use Mitsubishi locks and retainers to get rid of the old style "tractor" locks the early Hondas used.
The quench side of the head was welded to gain some HP and much needed swirl to get complete combustion. Basically, it was welded into a heart shape and it had the added benefit of boosting compression w/o having to shave too much off the head. With the head shave and planing of the block the final compression is about 10.6:1
A few years ago, Bryan made a run of custom adjustable cam gears. The machining on these things are incredible right down to the stainless hardware.
I mounted the same lightened fly wheel and transmission (82-83 GK 5 speed) to the new block and also re-used the A/T Engineering Intake with my dual Dellorto set up. With the larger displacement and better flow, I increased the size of the venturis in my Dellortos to 32mm from the 30 mm ones I was using with the EL.
I swapped in a Colt Cams reground cam with a profile that I hate. Once I figure out a better profile I will have a hard face welded cam done up.
My Pace Setter header was also re-used and will be exchanged for an A/T Engineering 4-1 long tube header once I have it ceramic coated.
While waiting for the head work to be completed, I re-sprayed the engine bay.
By late Summer, 2008, it was finally completed.
Over the winter I hope to have the distributor re-curved and swap in the new header and cam.
Next spring I hope to have it dynoed and have a time slip to see how it really performs
