im going to be running USDM ITR pistons in my lsvtec with eagle rods and im hoping to find a B16 head to cap it off, if i use a p28 ecu will i need a lot, if any tuning? and what is a normal/desireable a/f ratio?

 

You need to modify the ITR pistons to properly fit on the Eagle rods. Everything else you asked can easily be found by searching.

 

yea your gonna wanna tune.
