Forged parts usually require further processing to achieve a finished part.
Basically you can make a denser part than with a casting process. Which makes the grain structure tighter, and therefore stronger. :)
I would fit Wossner 11.5:1 - they are by far the best quality and price now and this is a better compression for a road car (mine detonated with any reasonable timing and pump fuel...). Bildon sell them for good money, but they are assholes...Quote:

I may have missed it, but what have you done with the rods? Reason I ask is that they're perfectly good balanced up and not worth the expense of upgrading (although the Scat ones are now very cheap).
Thanks for the advice. Although I have been told that it's better to take the material off the head and or block than to use High Comp pistons due to the fact that the high crown spreads the charge and can cause detonation and make the charge burn time longer. What's your take on that? Or due to the Head design, is it better to run high comp pistons? Also, i was thinking of only going 11.0:1, or would 11.5 be ok? In my experience my last 8v engine had 11.0:1 comp and it would detonate if i wasn't careful about the fuel/ignition.Quote:

Thanks for the advice. :)
OK.. this is what i've found so far to be the best prices for brands i trust..
Bildon Motorsport
Wössner 16v forged- US$549
Drag Performance (Ebay)
Custom JE 16v forged- US$600
Both come with rings, pins and clips..
I'm assuming Bildon will do wossner custom comp for me..
This Drag Performance mob will do any bore size any comp ratio in JE's for that price.. The only thing is that I don't know if the JE's price is for coated or uncoated.. And i haven't asked yet..
well get it happenin mate, the only way your gonna know is if you ask questions mate
great progress BTW
dom
Hahaha, yeah i'll email the guy tomorrow. And thanks man. :)Quote:

P.S. Nice rods :D
Ok thanks for the link. Yeah i figured as much about the comp, but wanted a third opinion.Quote:

Thanks. :) Not bad for the price.. Just a little cheaper than carillo's. j:.Quote:
