2000 Acura EL

Hey guys just looking into some better information and tips anyone has for building a High Compression D16Y8,

I currently have one in my 2000 EL but I bought another engine and transmission off a friend for $100 (for good reason, it was shit inside)

Cylinder 2 and 3 are both egg shaped at the top of the sleeves so there is piston movement at TDC back and forth between the sleeves (more than there should be)

I thought of building this engine up and swapping it into my EL.

First thoughts were to rip apart the engine of course and get the block bored out and decked so everything is perfect again and since the sleeves are warped I presume it would have to be machined evening out the sleeves making them a little larger ? making it a 1.7 or something like that ?

After that would look into some high comp pistons (not sure what size since the block sleeves would be a little bigger)

Then add new head studs, replenish the valve train, add a cam with adjustable cam gear, head gasket (not sure what thickness would be best) and put a tune on it as well then swap it in come spring time.

Going to try and gather all the parts and work on it over the winter.

Any input or information would be great ! Hope I didn't sound to dumb explaining it all

Love the Civic

pg6 pitons come up to 76mm in size and they are a oem piston. They are mostly a flat top so they will work great with a y8 head. As far as cams I would look at a Rocket motorsports regrind or a Colt regrind. The header will be the hardest part. There are really no good options for our motors. Just get a oem y8 head gasket.

This actually looks like a nice header as long as the description is right.

OEM Y8 head gasket can be used up to 75.5 bore but if you go 76mm bore than the gasket will stick into the CC and burn up. Golden Eagle takes OEM Y8 head gaskets and bores them out bigger if you decide to go 76mm.

Make sure you clay the motor to see if you need to fly cut the pistons for the valves at all too.

And that header does look great, would love to try it on my car.

Not ganna lie that header is sick in the picture, who knows actual quality and if it really is for a d series, anyways good luck on your build.
