Well guys its time...ive put it off for a long time. its time for the build. income tax came in and ive been colecting parts over the last few months. wish me luck as while this isnt my first engine build(not hardly) it is my first honda build. feel free to lemme know what you guys think.

Some history: well a few years ago i made the awesome mistake of going on a road trip without checking my oil or any of my vital fluids (its a Y8 remember...see where this is going). well road trip ended up being about two hours worth of 100mph+ coming back from northern california in the middle of the night....yea you guessed it SPUN ROD BEARING!!!! :wacko:long story short...replaced the rod bearings twice, crank was scored i knew it was toast. lasted about 8K miles. Knew i was gonna have to replace the engine so in a blaze of glory i dropped the clutch at 6,00 rpm and shot a rod out of the block. (on purpose...im a jerk):pinch: well now its time for the rebirth.

Build Specs:
Block: D16Y8 honed
Pistons: D16Y8 w/ oem honda rings
Head: D16Y8 P&P by me, Milled .020 and 3 angle valve job Exospeed
Intake: D16Y8 cut open and P&P by me
all bearings and gaskets OEM
CAI: AEM
4-1Header: DC
exhaust: custom 2.25 with borla muffler

Build goals: my main goal with this build has been to make the most of what honda gave me. i woould like to squeeze the most out of this combo without having to change the cam or pistons(only because smog rules wont let me) so wish me luck guys feel free to comment!!! oh an pic whores(myself included) pics tomorrow gotta get the camera from my chicks house tonight.

you could easily get away with a crower 1 in there for emmisions.

its OBD2, hes gonna have to have that for emissions so needing a lot of tuning wont work well.

i dont see why not. it can run on the stock ECU long enough for it to pass emissions and it can be tuned with a piggyback if you dont want to convert to OBD1. Basically what im getting it as you have a motor thats mild enough to run untuned but that you can run tuned via OBD1 untill your emissions time comes. I mean do they pull the dizzy and what not to see the cam markings? Its not gonna idle like some .400in cam or anything.

ok now im afraid i might have a problem. i was out in the garage last night planning shit and drinkin a beer and i decided to look at the block a little more. refer to the pick as there is a ridge right where the pen tip is. every cylender has it and i can def. feel it with my finger. is this normal? i have a hard time believing the block is that worn...it has hone marks and the pistons fit tight.
Image

lemme know what you guys think.
ok more pics....some of you seemed really interested in the manifold being cut open and ported heres some more eye candy
Image

Image

Image

Image

you can try and tig weld it back together but i couldnt get the filler rod to mix with the intake at all. ended up using aluminum wire feed.

ok now some more of the head work...its really hard to get pics of the exhause ports because the valves create a shadow, but i got some good ones of the intake ports. enjoy!
