I took out a 4AC 2 valves per cylinder that was not even cross-flow so it was like comparing chalk and cheese. I used a facet fuel pump located on the shocker tower it did use to make a little too much noise for my liking but i just lived with it. I did a lot of porting tricked up the carby.
if i drove easy and didn't put my foot down it did better fuel economy than the old 4ac
Myles,
get yourself a factory toyota K engine manual and work slowly threw the tune up section you will learn as you fix the problem, Then if your still stuck pm me.
I hate when I pay utility bills and they send an overdue Account so I pay that too then next time I have a massive credit.
IMO It really borderlines on fraud sending out a second account when the first has been paid weeks earlier.
