Bills 2.5-turbo build, pic's of machined parts Options

[Bills914-4]

here's a few pic's of some parts I've been working on

1700 heads I've modified at work, from this


to this (machined step & groove), chamber porting was done
at home , needed more cc (61) to get compression down








custom 100mm JE pistons ( thank you Charles @ LN engineering)
machined piston crown pocket (9cc)

Here's a few pic's of the flywheel clutch & pressure plate ( 228mm twin disc )
Kennedy Engineering ( www.kennedyeng.com/clutches ) it's a little on the
heavy side , but that's ok , the small intake ports & cam I'm using I think it'll
still be snappy , thanks for looking Bill D.

we were going to do the discs with organic material , but he could not make them thin enough ,
