I guess I'll post my build thread over here, seems like everyone loves the big power turbo setups... I'm building (again) a 12.6:1 D16 for my CRX. Power goal is 170whp and 130wtq, on 93 octane. I built a similar engine before but I had ignition problems (loose metal in the dizzy) that made the tuning difficult, and I went back to 10.5:1 thinking the compression was the problem.
Bottom end:
D16A6 block
OEM D16 crank
ACL bearings
ARP rod bolts
sharpened main girdle
shot-peened rods
PM7 (ZC) pistons with casting smoothed out
Hastings Rings
open oil holes on bearings
open and smooth oil pump channels
new OEM seals
new OEM water pump and timing belt
sandblast and paint block
Head:
D16Y8 head
ported and smoothed (not full polish)
remove hot spots and casting marks in chambers
Crower springs/retainers
stage 2 Crower NA cam for now, moving to stage 3 once the engine is running for a while
AEM cam gear
fresh OEM rebuild
Y8 3-layer headgasket
Most of the stuff I have already in the current motor, the changes will mainly be the work done to the new block, and the pistons/rods. The bottom end work is stuff I found on Endyn's site. I'm cutting down the edges of the main girdle so they are sharper corners to pull excess oil off the rotating crank. The oil passages in the pump and pickup aren't smooth, they bore them from two directions at the factory and install a plug, so I'm adding epoxy to the corner and smoothing/matching it for better oil flow. The main bearings' oil holes are smaller than the ones in the girdle, so I'm opening the holes in the bearings to match.
I'm still debating bigger injectors, my friend's 160whp NA D is getting pretty close to hitting max duty cycle in the high end, according to the Power FC, so I may try to get some Prelude 345cc in there. He's also on a pretty conservative tune IMO, my current setup can just about keep up with him. I already got the AEM FPR, but it's not installed yet as I don't have a pressure gauge.
I'll probably continue tuning with Crome on my P72, but I'm considering biting the bullet and going with a full Neptune setup, a friend of mine just got it and loves it (bluetooth FTW).
I've got everything I need pretty much, the block is totally taken apart and everything is cleaned, I'm planning on having the bottom end together by the end of this weekend. The compressor broke recently at the shop so I can't get the porting on the head done as easily... might go hit the student machine shop to git er done. I also have to figure out where and when I'll get the head cleaned and resurfaced before I assemble it.
Here's a pic of it now... it'll probably look exactly the same except the engine will be a bit cleaner:
