Hi,
Ive had an offer to buy a 4Y EFI motor at a good price and wondering if it is worth doing the swap,
What sort of power, fuel consumption improvements do i expect to get?
3RZ is the better option i know, but as i have had no issues with the 4Y and this has come up cheap im thinking it would be a reasonable change

Don't even go there.
The amount of wiring and additional sensors and parts you will need for absoluetly NO gain, you would have to be carzy

What he said. My stepfather and I swapped an 18r for a 22re motor as it was cheap but still had many head aches, helped a heap having a mate that's a really good sparky though. Efi is good as it wont stall on hills compared to some carbys though.

Thanks, Im gonna go the 3RZ Route,
Ive had a quick search and unable to obtain if there is a difference between a 2wd 3RZ Sump and a 4x4 3RZ Sump
Just dont wanna squish the Sump

i run a 2wd sump on my 3rz with x over steering, have a tiny rub mark not even a indent on the corner of my sump from up travel, must only do it when moving because when i stop with it flexed to max up(well as much as it gets stopped, would appear it flexs a tiny bit more whilst moving due to the rub mark) it still has 10mm of clearance

I might just lift my Engine/Gearbox at the same time to match body lift and then i wont have a problem

i would try and avoid that at all costs, lifting ur engine and trans 3" will increase how top heavy ur car is, 3" body 3" spring is a pretty tall hilux, having ur engine 3" up will IMO make it abit flop happy.. i would mount it in the stock position and i dont belive u will have any probs, epesh if u have stock steering.
in this pic it was not rubbing
