the efi kits are tricky and alot depends on what your looking for in terms of performance. the TBi kits are ok but really old technology. the MPFI kits are really the way to go these days. megasquirt is probably the cheapest way to go so you can scrounge parts but it requires a large DIY effort. you can put a kit together for under $1000 that will support 350 HP. obviously if you want more power then you need to pony up some more cash. the accel and fast efi kits are really nice and are as close as it comes to plug and play efi, however, you still need an MPFI intake and some fuel rails.

we can do manifold mods and fuel rails for you if your intersted.
