I cant take it. i need class under my A$$ lol...thanks
Would be easier and cheaper to leave the pump/injectors alone and just install a turbo with really chitty oil seals. Free unlimited RPM.:woohoo:There oughta be some pulls coming up soon, I still need to get a new bigger set of injectors on the way, but that's not a necessity. When that happens the PT pump is coming off to have some more rpm coaxed out of it.

I may not get to it this year, but I may look into having one reground to increase injector travel, for now I will be trying those larger injector internals to see what the do with standard lift.
You found them somewhere ?
High lift cam needs modified injectors or they will not last long, I think stock injector is made for max 6mm travel.
Factory twin turbo 855s have a lift of .266" versus the .224" of the standard engine, STC has .272" and standard parts will work well with all these.
But not with 10mm travel, they need modified lubrication grooves. And very big nozzles or something will crack from pressure.
I know only one man who does them and he lives here in Finland. Others have tried but their injectors usually failed quite soon.I have heard about the big lift cams but never any information about the injector parts used or even where to buy them.
