8 Hours on the engine so far, ROAD RACE HOURS NOT DAILY DRIVING, I do not know milage because i have a 2006 RSX Type S tranny without speedo.

Will post dyno's when I get them scanned.

THIS IS FOR BUILD INFO AND DYNO SHEETS!

Please follow TOS in this thread, ie NO FLAMING!

retuned at RLZ in July and made 232 on their dyno. injectors took a dump on me first lap out at CMP in kershaw SC. car missing and short shifting at 6-7k i still ran a 1.49.7

retuned week of oct 5th 2009....power was the same, up'd the rpms to 8200. took it to VIR again for oct 10-11 NASA MidAtlantic weekend. Ran a 2.10.2 on 3 year old hoosiers and NO AERO to the car and stock lsd....lsd aero and tires will net me at least 3 seconds a lap, i just don't have the 4000 to dump into all of that right now!

is the K24a4 block better to build off of then the a1? i see that you guys are using the A4 block. I plan on using the TSX pisons and rods in my build, but just wanted to know which block is better to start with, or was affordability a part of the block choice?

we will see soon, i kept the bore at 87mm, machine shop said the cylinders were still good, so it might be a lil harder of a task for 300 now but we will find out soon...

going to pick up the freshly polished and scoped crank and the welded, honed and decked block in 2 weeks
