Everything was basically finished...daily driver status was never going to happen with 14.1 compression but i did enjoy the car a dozen times or so around town....N/A is awesome but another thing that pushed me towards boost is I'm going to compete in SCCA this year and the SM class I'm in has nothing but egos and Stis...so in order to be competitive I'm going to need to be a lot faster...i already have them all by 1000lbs but they have 4wd and turbos. I was running cops on the setup something is wrong with the distributor using it as a COP and I didn't want to keep trying to figure it out or spend more money changing to a different setup..

Reno your right i came to that point of either spending more money or building something a lot less problem free with a lot more power.

Yes very good supercharger....im using the c30-94 with the 105mm pulley....i believe the guy above was using a smaller charger and 90m pulley on his stock engine...this one is capable of 16-17psi and 400hp....think that is plenty for me not trying to go back to the future.

new Pistons are in and block is in the shop...83mm 10.5c/r with ceramic coating and friction reduction coat on skirts...strange to see how big a difference 83mm bore makes with compression dome height...first picture is 83mm 12.6c/r with a normal 20v dome then at 83mm 10.5c/r the pistons are surprisingly flat...dont know if you can tell in the pictures but if you can see where the rings go on each piston you will notice the size difference between n/a pistons and pistons for boost. 

Heads all done....CNC ports, 1mm oversized valves, Bronze guides, combustion chamber has been cleaned up as well. 38mm exhaust ports as well. Valve buckets are currently being DLC treated as well. 

Also has a custom plenum made for boost....came out pretty nice

lastly I've had this for a while but wanted to thank Moto for helping me get this awesome seat since my other bride seat shrunk and I no longer fit in it. lol

update more when the block gets back from the shop

260s at 10.7mm lift intake and 210s at same lift for exhaust although the exhaust was flowed at 35mm bore and now it's 38mm so probably a few more cfm from the 3mm size increase. These numbers are at 28" water also..
