Thanks, the S14 is primary for track use but it still gets driven on the streets for break-in or wild rides. 


The 4 rotor is very close to assembly, hit major speed bumps in the rotor/balancing. Otherwise she is ready. 


We havent had time to re-visit the high hp n/a 2 rotor stuff, and dont really need to. Some quick division of our 3 rotor horsepower would make a 318 rwhp 2-rotor with semi p-port (identical setup) If we reach 500rwhp with the 20b that is a 334 rwhp 13b. Until the 4 rotor makes more power "per rotor" than the 3-rotor, semi p-port is still king for highest horsepower recorded.

On a quick thought process the 4-rotor doesnt seem a lot more than 20b, but its a 75k proposition on the low side. Add to that I'm not a fan of the swap without moving the firewall, as the extra length is just too much to pack in otherwise. I wouldnt worry about the fat iron on a n/a 20b that is for sure. We are looking into building short crank 20b's to fill the lack of OEM stuff. Only bad thing is they have to be full p-port which isnt very streetable typically. Its about $3k more vs. Mazda 20b once both are rebuilt/ported/custom intakes etc.

Ok so I take the blame for this getting off track, I stated many things that needed rebuttal. 


So some ending points- I know much more about LS than your average bear, and I own domestic V8 stuff.

Hmmm, trade for the Rx4......that is tempting!


So I finally figured out how to transfer some old videos to youtube and edit them. This was two years ago, open track day. Not going all out on the car, but its cool to get an idea of in-car
