I have a 1st gen b16 swapped into my hatch and about a month after I put the turbo on it started puffing a lot of smoke. So, I did a compression test and 1-3 read around 190 and #4 read just below 90. So, I pulled the head off and the #4 piston out, to find out that I was able to pull 5 chunks off of the piston between the rings. And my question is will a USDM b16 piston work on my 1st gen JDM motor or is the compression going to be different?

Thanks
Brian

 

ah why don't you try using the search function. it is the button in the top right.

 

Pretty sure it will work...but why replace with a forged piston? since you already have the engine apart.

 

usdm is pr3
89-91 jdm is pr3

if your piston reads pr3 on top, then head to ur local honda dealer and u can order one piston
if u want u can buy a set of used pistons/rods for about 50 bucks

might want to check clearances though, might need to go with .25 over pistons

 

I really wish I had the money for aftermarket pistons. But I kinda got screwed on money when I spent about 900 bux on new rims for my other car and then a couple days later someone stole my wallet that had about 600 bux in it from selling my old rims.

 

Damnit Bart I was standing 5 feet away from you when you posted that. Keep this up and I may just sell your tires

 

Speaking of my tires where the **** are they? I paid you for them like 5 months ago you delinquent ****! I want my mudda ******* Azenies biatch!
