Series 4 information needed

[fastg]

I run a Kpower conversion on my Locost. I had a prototype KMiata (as it was in those days) adapter plate to do my mockup. Quality stuff but there are a lot of conversions kits available as the K Series is becoming the SBC of the 4 cylinder world. I would suggest you pick the conversion to match the transmission your going to use. The Miata 5 and 6 speeds are good. If you going to do track days go for the 6 speed, but they are getting harder to find. I have a 5 speed sitting in the storage unit. If you going to stick to NA either will do. If you looking for power adders the RX8 or better still the Nissan CD009. The CD009 is very tough, was in a lot of vehicles and can be picked up new for around $2000. I have a complete conversion for a T56 but I will never need that much power capability. The K Series motors are very stout, easy to come by and an amazing availability of parts. OEM Honda parts are surprisingly  inexpensive. My engine was out of the 07 TSX, cost me $1k but I sold off the AC, Altanator, PS pump and inlet manifold, so I probably have $500 in the motor. With a set of Drag Cartel cams it dynoed at 240rwbhp. I am currently installing a 4Piston racing head with matching inlet manifold. Checkout

The only problem with the K Series engine is it's very tall, the K24 is about 3/4" taller than the K20. A dry sump system would give you a little but more ground clearance, but not a lot because the bell housing clearance becomes the next issue. Most of the height comes from the cylinder head. You can get a custom cam cover that saves 3/4", it's a lot cheaper than a dry sump system. Oiling is not an issue with a wet sump so a dry sump setup  is an expensive luxury.
