4agze or 3sgte? Which is Easier to Install, in a 94 st coupe Options

[Kplaya05]

Hi, just like the topic, which is easier for an engin swap a 4agze or a 3sgte? i havent really seen to many posts about the 4a-gze and i have even did a search on it and cant find anything.

What kind of car does the 4agze come out of and what years and is it easier to put in a ST than a 3sgte?
About how much would it cost to do the entire swap?

Thanks, Kyle

Both swaps will require a good deal of research work to get them to run properly and reliably if you do it yourself....so its hard to say which is easier or harder to install. However, do realize the 3SGTE has been swapped more frequently than the 4AGZE so the work involved is better documented and drawn out for you. There are many people who can assist you with the 3SGTE swap and getting wiring completed, where there may not be as much help at your disposal in making the 4AGZE swap happen.
For reference to swapping your ST, be sure to read through the ENTIRE sticky in the FI forum that defgeph wrote up about putting the 3SGTE in an ST. Everything you need to know is in there.

The 4AGZE was found in the MKI MR2 Supercharged overseas and in the US, as well as in the Toyota Levin in Japan. Both engines have parts available in the US, however the 3SGTE has been used in several platforms here where the 4AGZE was only used here in the MR2 for two years....and thats it.

Do lots of research before hand about the two motors and decide which you want. Expect a ballpark range of about 4-5 grand for either project to be completed depending on how much work you do yourself.
