the twinscrew does sound gay will have to save up for the Lyshomo instead
Ive looked at using the Honda D16z6 crankshaft modified to fit the g16 block but theres just too much work considering the stock g16b crank could handle 250hp or 180lb of torque ate before it causes issues from what Ive read using H beams not the piddly factory rods.
Just for a contrast 10 years ago I went into Suzuki carbusters and Deon the onwer at the time showed me an engine dyno sheet for their speedway 1070cc g10b with g16b head ported 50mm ITBs , serious gear inside it drinking methanol making 196hp ate @ 10,500rpm then one of the billet alloy conrods let go and went for Ti rods higher porting angle to only gain another 4% or so peak hp. I cant remember all the details but it was a beautifully put together setup with dry sumping ti retainers and other custom go fast gear that wasnt easily available for the G16b head but mainly one off custom.
