Ok, I read every tech write up on boreing B-series motors last night and it seems that people were arguing its worth on a b16 staying N/A. Has anyone done it? What compression piston did you get? Did you do head work too? Eventually I'd like to go FI, so maybe I'll by the pistons for an FI application (I will have a spare block, so no downtime) and just save for the turbo.

With an 84mm bore/sleeve, it seems you will only reach a little over 1.7l of displacement. That seems a little disheartening for the money. Would getting longer rods/ different crank help or would that not be desirable to change the b16s highly touted rod/stroke ratio.

If anyone has bored and sleeved a b16 to 84 mm+, please respond and let me know your results (FI or NA). I'm just trying to figure some crap out. Those damn b18c longblocks are so expensive, considering I already have a b16 at my disposal.

Also, this will be a street driven car if that matters. It's my only car as of right now.

Rick, who is trying to make the best of what he has, or make a sensible decision.

 

resleeve the b16 block and if turbo keep it to 84.5mm .... if all motor get it to 85 or 86mm. Those thing makes ibecause it peaks much higher than the gsr and typer because of much higher conrod ratio.

I will be boosting...seems there is no other way.

 

How would boring a B16 to 84mm only make it a 1.7? Wouldn't it be a 1.8 then?
