nothing wrong with the 4af/4afe engines

I am a little curious to test out the 4afe though. See if I notice a huge difference or not.
but ren is right if your gonna do something like that the easiest way is to swap a 4afe and what is even easier is just get yourself a complete ae92 sr5 with a shit body that runs and use that as a donner. RUNS well is the key though lol. Or if you wanted to you could use that for all the stuff but the engine and tranny and buy another 4afe.
and how bad could your milage be? it's only a 40 liter tank and on 20 liters yesterday I did almost 300 km! and my carb isn't doin to well....
