Here's the short story, my friend has a D16Y8 in his 97 DX. He put a ebay turbo kit on it and didn't tap the oil pan properly, which led to a spun bearing.

He's looking for a quick and easy fix.

Advance auto parts qouted a remanufactured crankshaft at about $225; all new bearings for about $50; and a reman'd rod for about $80. (not 100% sure on the exact price on the parts, I do know that the total with tax was approaching $400) (this is what his dad would like him to do)

The other approach. There's a local machine shop that can mill the crankshaft for $125, he could get the bearings from advance auto for $50, and remaned rod for $80, (or have the machine shop machine his rod for $60. Total parts about $225, or $205 if they machine the rod and crank (He's leaning more towards this idea)

My thoughts. A local junkyard has a 96 D16Y7 complete block: rods, pistons, crank, etc..., for $200. My friend doesn't like the idea of a y7 motor in his car again though. I tried to explain that we'd obviously be reusing his Y8 vtec head, but he doesn't want to consider that. Isn't the Y7 bottom end better for boost since it has lower compresion pistons? (I thought I read that somewhere on here, maybe I'm wrong)

Just wondering what you guys might do in this situation.

Thanks for any thoughts/input you may have.

 

He is going to have more of a headache with sizing the bearings correctly with his current troubles. I would say for ease of installation, go with a factory built block and call it good. Does he know what is all involved with machining the crank and then bearing re-sizing?

Probabley not. He's just looking for a quick and easy fix (if that's even a possibility).

If he happens to mess up on the re-sizing, which is possible when trying to cheap out on autozone bearings, he would probably end up spending more on sets of bearings than he would to just get a new block and headgasket!

 

get Y7
thicker head gasket and block guard

 

make him get the Y7 block. If he did, he would have a couple of options available...

1. Y7/Y8 mini-me. yes, the Y7 has a larger dish than z6/y8, so slightly lower compression should help with detonation on a turbo setup.

2. Use the Y7 crank, block, and rods, with his Y8 pistons to create a D16Y8 that has D16Y7 stamped on the block.

3. Use the Y7 crank & rods in the d16y8 block, so he doesnt have a *** fit about having a d16y7 in his car.

obviously, the most economical option would be #1. slap some sense into his head and get the Y7 block and throw it in the car.

 

Thanks everyone for all the input.

 

how bout be smart and just buy a b series ... or just pay a couple of hunderd of a zc sohc vtec that motor does wonders and the tranny gears are sick..
