Engine swap, 4S-FE for a 3S-FE

[Blister]

Hi there,

I hope someone has the know how to answer my query, I have a '95 Camry ZX automatic front wheel drive with a 4S-FE engine which is leaking a bit of oil (not really sure where it's from) and there is also a bit of blow by so it really needs an overhaul, but I can pick up a '94 3S-FE for about $500 whick seems to be in very good cond. So I was wondering if these motors could be swapped without any problems or modifications?

Appreciate any help regarding this matter, the other option of course is to go ahead with the rebuild, I can sourse the parts reasonably cheaply but it's much more work!

Cheers

You might need to swap over the ECU, injectors, AFM (if it has one) as well.
