Is there a way that i can make my 4a-f carbed, into a fuel injected, there is the 4A-fe which is fuel injected and isnt it the same motor except for that difference??

i just want to have a fuel injected motor (cheaply) and if that is any cheaper than buying a whole new motor and dropping that in, than i will do that!

4A-FE has a different head, the head has injector holes machined into it... but you can make a stand alone EFi system into the 4A-F.

Probably not. Think about MAP sensoer, cold injector, ECU and wiring harness. Easier to get everything and drop it in. Then why not go for 7A-FE or even 4A-GE since you have to went through all those trouble.

Its not really that hard to rig up a EFi setup.

so whats the best thing to do then, hook up an efi system, or drop a new motor??

or should i say what is cheaper?

Not hard as long as one know what to do. A swap maybe less headache.

so if i went to the local junkyard here and found a corolla sr-5 or gts, i could use the motor and ECU from that, and drop it in mine?? are the motor mounts the same, cause thats my biggest worry, i dont want to have to change those!!

definately less of a headache to swap in a new one. But I'm always the one that takes the harder route... so I guess I'd be the one making a manifold for an crazy EFI setup
