Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

    you guys do know base model rsx pistons put it at 11:1 and a safer piston to valve clearance. F23A1 block/crank/rods, k20A3 pistons, F22A6 head, skunk2 IM, 70mm TB, custom header, and a custom grind from web cams and you'd have a 230-240whp brawler.
    So slighty higher compression and .1L of displacement more than what you're currently running and the results will be 50-60whp higher than your current numbers?

    And static compression ratio numbers don't paint the entire picture. The swirl bowl in the top of the K20A3 pistons is not conducive to use in an engine trying to make an efficient, powerful burn during the combustion process. And by the way, they would only make that combo have a roughly 9.9:1 compression ratio.
    My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!

      Where are you guys getting these numbers from? It's so much easier to run a K20 piston in the F23. What was wrong with that idea (besides using K20 rods like Jarrett explained)?
