sup guys im some new on hondas so i need some help first i got a b20b with b16 head turbo sotck bottom end stg1 turbo web cams 450cc injectors 255walbro pump xs power turbo at 10psi and jdm pw0 ecu. no dyno and cause of that my 2 pistons are gone and 2 sleeves also what do u guys recomend me 2 buy like pistons if should i stay with my original obd 0 wiring harness or change it to obd1

 

Buy an ls.... better walls for turbo. and convert to obd1 Wayyyy more tuning capabilities. conversion harnesses are pretty cheap.

 

get it tuned before you smash out on it. i recommend obd1 upgrade

 

on the upgrade u ment by the entire harness or just the jumper harness

 

that would be up to you. i build full complete harnesses, but you can also use a jumper and then do the rest of the upgrades
