i have a question for you guys, what is the difference between the 4afe and 7afe other than the liter. is both engine identical, are you able to swap in a 7afe into a 4afe with ease, im pretty sure the ecu is different, is the engine harness also different, any different in sensors, or is it a plug and play setup between the two. if you guys can be specific about the differences i would really appreciated, thanks.

7afe has a knock sensor, 4afe does not.

wiki it. they will tel you the difference.
if i remember right.
one has 3 speed the other 4 speed auto.
one has just 5 or 10 ore hp. makes a difference. check wiki about it. tells more specs.
since your hmong its just like haveing a cx and a dx. cx is the 4afe dx is the 7afe.

will FYI this is not honda.. all the stuff u told me i know bout it already n it not close to helping me on the harness.. plus i say specific about the differences about the motor so i dont really have to major change wire o yea wiki don't tell about no harness, senor etc. just liter n power which i know already..thank you very much for not helping at all.. o yea all hmong pple dont own a honda like myself..if i look at the cx ang the dx wat is the deference on the motor i bet u their exactly the same which is a d15 just optional on

they have VERY different torque curves.

hey ypu guys are hmong too... nice hmoob yaaj here... LoL! i know this thread is old, im just bored rite now but yeah... if you want, id say build a 7a block with a GE or GZE setup with it, and run turbo, but IMHO since we are hmong ppl this car is more for commuting and trying to show something different at fresno new years... LoL! but yeah the 7a is a better setup than the 4a is... like a d15 and a b18 something like that, but since you dont have a honda. its sad that were using honda as examples for our beloved toyotas...

7A-FE has a rigid aluminum upper pan and better bracing to the transmission. It's built to handle the extra torque better, both are plenty strong blocks.
