I noticed in your introduction you said there were some weaknesses in a G180. I am currently rebuilding a G180 block w/ a G200 head. had the head shaxed 20 thousanths, getting the block bored 40 thousanths, getting the cam redone, asked for a custom grind, to work best from 3000 to 6500, getting an offenhauser intake manifold, doing the port and polish on the head myself, want to get a weber 32/36, made a custom sealed air intake, i am hoping to make around 150 horses natrually aspirated power, and saw youre making 580hp!!! i really dont know much about turbocharging

so can you clue me in on whats weak in a G series and about turbocharging?
thanks a lot, Jared
Jared,
The main weakness in the G180 is the timing chain,here in Aus we can buy a double row kit for them and that fixes the problem,also with the G180-G200 head,you cant port them out enough to make the power you want,you need the G161 head that we have here in Oz,also when it comes to porting,leave it to a proper cylinder head specialest.The power your after sounds a bit high,even if you get close your going to need EFI to do it or twin 45mm webers,the single 32/36 wont be enough....

Darren
