Where would I get some je pistons for my 420a? I tried ebay but can't find any. Is there an alternative I can use? I'm leaking oil burning alot of smoke so I need to prep this car for turbo and make it running new again. Let me know guys!

Also what else should I replace for optimal performance?
 
There's quite a few pistons there, which one would be optimal to choose? I already got a set of Eagle rods so that's one thing. :D

well if your are for sure going turbo and want to run some reasonably high boost, go with the 8.6 compression. but, you will lose some power unitll you turbo. but if a turbo is a ways away, you may want to go with 10.5 compression. give you a little power before the turbo, and can be used with the turbo, although boost must be kept lower and its a lot harder to tune
 
unless i was mistaken i thought i only saw pistons for the 4g63 there (and rods) hold on let me check again













....










still checking....











Yup i was right :p
