I thought some of you might like this...? Taper bored from 76mm to 80mm, which is the absolute limit for this unit. No idea if this would add any power to the 2UR... but it is a possibility. It was built for my supercharged 3UR. I might be up for lending this out to someone in New England to further the cause.

 

Thanks for sharing. I wish I was in the new england area or I would take you up on this offer.

 

I have a great set up to hit the dyno with that. full bolt ons, ported intake manifold and nitrous with pump and race gas jetting...

 

What's the bore on your intake manifold? Where in Vermont are you? I can almost throw a rock into Vermont from where I live in Massachusetts.

 

I don't think boreing out would help in HP but it will help in throttle response and probably make it smoother to...

 

I don't think boring it without a whole host of other mods will make a noticeable difference unless it reduces velocity, then it won't be good at all. There is too big for sure.

 

Hit the dyno so we can see if there's gain or not.
