So ive been pondering with wither or not i should keep my 83mm pistons or stick with stock pistons on my coupe build. So im looking to you all for a detailed list of pros and cons on running 83mm pistons on an AAN with stock crank. Now i already have the pistons, and all the parts for the build. Just need to take it all in to the machine shop for the block to be done.
Bit of a back story, i bought a 90 coupe quattro project car and it included all the parts i need for the 83mm build minus machine work. So cost albeit is a factor for most when considering this type of build, for me its not a huge concern as i have all the $$$ parts.
my main condern is with 83mm, does it thin the walls to much?, does it limit how much power i can push on the block? Does it reduce reliability on higher boost applications?
Pros
- more displacement (2.3l)
- more power ?
- more TQ ?
- cool to say bored to 83mm
Cons (pertty much all $$$)
- cost of pistons
- machinest costs (can be over 1k)
- custom headgasket availability
- custom tuning ( every car needs it i suspose)
- reliability (is this a factor)
- cyl wall to thin? ( is 83mm to much ?)
Id like to hear what everyone thinks.
