Ok then if i were getting custom pistons made up for application of boosted 16v stroke is fixed by crank at i think 86mm, engine would be 1.6 litres +ish what is the ideal Compression ratio? discuss....
what power you aiming at what boost what method of controlling the engine? (ecu type and features for example)
yea has both cheers dude will have to look into the maths then!! can you reccomend/supply custom pistons/rods people?
obvious people are JE... but also worth searching out peeps like these http://www.importperformanceparts.net/ who seem to have a heck of a range.
Cheers alot mate Have mailed a couple on there, see what they can suggest! anyone know what the mounting side of a G60 TB looks like? is it two joined circles like a G40 one? with 2 butterflys? or one big hole?
Watch importperformace/flatlander though. Their shipping prices are mad! Set of head studs, that'll be $96 sir! It only cost $98 for the bloody rods!!!!
The best CR for most people with a modern setup (modern fuel, recent turbo's, etc) is 9:1 This allows you to have a better spoolup, better downlow torque in low rpm's (offboost), better performance at lower boost levels (in other words, no need to run crazy boost levels, when it comes to boost, higher is not always better).
