nice figures LB

What will be the new rev limit with 1.8L setup? I think main the gain would be on mid-range revs...

And do you have any acceleration video with rotrex setup ?

Is that all you're changing LB or will you change cam as well, would be nice just to see the true difference of what the bore and stroke will give you.

I wonder if the w/m will gain as much now that you have the pistons and chamber coated ?

gains with w/m should be awsome as the charge will benefit from the cooling and density without the chambers heat sink effect.

HOLY CRAP BATMAN!!!

I love a good bore/stroke engine build. Back in the 80's, I used to do the 350ci to a 383ci or more! This will be a fun one to watch.

Well... the money tree is looking a little sad right now . It's growing but slowly. I'm taking my time and changing / adding all kinds of things which is driving the budget higher. I figure since I have it apart I might as well do everything I've ever wanted.

The problem I have know is my crazy wife and how much she plans on spending on the four kids at Christmas. Yes, she starts now. Those frigging kids are killing my fun. Man they are lucky I love them .

What ya gotta do is buy them the parts for Xmas.

A cam for one, pistons for the other. And then you tell them that will show them how to play with them.

Well...

I did manage to pull together some more cash so the project is rolling again this week. I'm thinking mid December at this point.

fun looking build! Rotrex superchargers have blown up in the s2000 scene as well. What size blower are you using? C38? Will it be run off the stock accessory setup?

I think you passed the "S" long ago (lol). At this point your car has moved on to another letter, proabably a "z" !

Looking forward to pics and insane dyno charts.

Living vicariously via LB mini since my son took the mini to college and am relegatted to driving a 135i. Running 340 HP at present w/ a mild tune so I am having some fun.
