I've been reading up on this and it seems the preferred way is to get a marine intake and modify it to work with the truck engine. I've also read about the MFI injector upgrade but so far I don't see any indication that one can increase fuel flow that way. Are there any larger injectors for the spider injection system or do I need to get an intake with fuel rails?

 

The MFI spider actually has smaller injectors than the SCFI spider so if you are in need of higher flow rates, then that is a step in the wrong direction. There are no alternative injectors that can be used with the spider style arrangements that I am aware of. I haven't looked in a long while yet either.

If you need more options for injector flow rates, then the marine intake is the ticket.

 

Wynjammer has a new marine intake in Als Garage

And a larger spyder assy. as well

Man he's pricey. I'd like to have that marine intake but will it pass emissions without EGR?

 

No idea, I'd say the best thing would be call or email Al.
