Hey
I want to get a set of rods/pistons. I am just wondering that if i have to keep stock compression or not--because when i have to get emissions done (obd2) i have to return everything to stock so i'm wondering if i get pistons that will lower the compression the stock settings / ecu will not work? or will they?

Or should i just get pistons that will keep my compression stock? (i have a turbo d16y8 btw)

Anyone have any experience on this topic? Thanks

It'll run fine on a stock puter' and injectors w/ lowered compression.

nitecrawler

really? that solves ALOT of my headaches

yeah the compression will be fine....but why go lower? 9:1 range is fine, just fine.

nitecrawler

Yeah but 9:1 is lowered...

FooK

i said 9:1 range...what motor do you have?

nitecrawler

d16y8, i guess its low but isnt lower better

FooK

lower allows you to run more boost on pump fuel before dealing with detonation issues.

you lose some low end in the deal tho.

personally, i'd rather keep it in the 9's. its kinda an "all around" good comp. ratio to go with being you dont loose low end power and you can definatly build it to make lots of power!! imo 8's is just too low

so when i purchase aftermarket pistons should i go with 9:1 or stock comp?
