Looking on Rrm they have a timing box and piggy back for the ecu idk what to get first ? Help any reviews ?

 

Neither. Get a Tactrix 2.0 cable and look at the two tuning options we have for the RA now. Either will do loads more than the timing box and piggyback combined.

you'll have to do some research depending on which method you want to go with. Each has a different set of software youll need.

building an engine isn't as simple as just throwing in some forged pistons, all of the tolerances are critical, and may require an overbore for proper PTW gap. if you're serious about it, bring a block to an engine builder who is familiar with 4G6x motors and they will be able tell you what piston size you need...87mm might work.
