I'm working on my LS/VTEC setup, I'm trying to use a 95mm crank from eagle. Plan on using stock length Eagle rods as well. Anyone see any clearance problems using USDM ITR pistons. According to my comp calc, with these pistons, the compression should be 11.46:1. Anyone think I'd need to make the valve reliefs any bigger to clear the pistons?? Any other questions, comments, flames are appreciated.

I'm gonna run the 95mm crank, because of the displacement being 2L, and the Rod:stroke ratio is gonna be 1.44:1, which to my understanding, is perfect for high revving, and stability. I plan on revving to 9000RPM, and making peak power at about 8700.

 

i have a eagle 95 mm kit in my b20 it comes with special rods and piston dont know about itr stuff will work

 

According to Summit, where it gives details, the rods are the same length. The pistons however are dished pretty good. According to comp calc, it'll be 8:1, which is way too low for my all motor setup. I'm gonna need something to get that up to 11:1 or better, but not anymore than 11.7:1.

 

I can't find any information. I read countless books on engine building with no results. I don't think I'm gonna spend my money and get something that isn't going to work. I was looking at the pistons, and they only have 2 valve reliefs. I don't know how that would work with high lift and duration cams. The dome pistons have -11.2cc worth of dome displacement. Things just don't add up. I think I'm gonna run stock stroke and bore and run ITR pistons.

If anyone has any information at all or any ideas, I would greatly appreciate it.
