Better Rod/Stroke Ratio LS/VTEC

- Sun Aug 14, 2011 9:29 am #267505 Okay, according to the compression calculator, If I use a b18b1 block, b17a head, b17a crank, custom eagle 140.48 mm rods, b16a pistons, Ill have a 1677cc or 1.7L b18b LS/VTEC with a 1.74 rod/stroke ratio. Good Idea or Bad???? Oh also a 11.14 compression ratio.

Its basically an oppurtunity to build a b17 with b16 rev capabilities, but still retain the little bit of extra torque that comes from being a 1.7 liter. Not to mention fresh rebuild.....Any other opinions on the matter???

I say do it. The biggest thing I hated about my B16 was the lack of torque and waiting for power. This would help out with that. I hope you do it and post up a build thread about it as I know i would follow it. I LOVE seeing engine build threads. :thumb: :thumb:
