3sfe to 5sfe?

You could also check into getting a 3S-GE. I used to get 30 mpg when I used my car as a computed. A 5S-FE would be a good choice also. I thought about that before doing the V6 swap. It would be a good torquey motor for auto-cross, but I like the power of the 3S-GE, I like the V6 even better .

 

well there are certain things to the 5sfe that people like. it has a good mpg, it was used up till 2000 i believe so parts are accessible and new, there are more performance parts for it, and it is a stable engine. there are things however that i like about my 3sge that make me want to keep instead of swap over to a 5sfe. i like the g series heads, i like that i get better gas milage on the freeway than my girlfriends camry with the 5sfe, i also like "claiming" that it was a limited production engine. in all reality i would say that a smart choice would be upgrade to the 5sfe. there are more accessible parts for it and it is not hard for people to work on. i have had the usual problems with it though. leaky valve covers, leaky distributor plug o-ring, and sticky throttle valves. also the thing i dont like about that engine is the ignition coil is inside the cap. but these are all personal problems and preferences. its an outstanding engine for what it is. an f series head that produces a good amount of power and torque while still giving the better end of gas milage.

 

it is a direct swap. s series engines have the same mounts. however, you do need to change over everything else if im not mistaken. check out celica tech for more info and i know there are a few guys on here that have done it also.

 

Well just quickly thinking about this with the exception of just putting in another 3sfe engine you will need

- new engine 5sfe, 3sge, 3SGTE
- correct ecu
- correct maf sensor
- would be nice to get the correct wiring harness
- if you get a gen2 3sg(t)e it would be nice to get the proper fuse boxes for the engine bay
- different rad hoses & possibly a better radiator
- some exhaust modifications

If you go turbo you will also need

- an intercooler radiator & pump for gen1 3sgte
- a return line to the radiator for the gen1 turbo coolant
- to cut a hole in your hood for a gen2 3sgte tmic

 

Hard to say.

A 90-93 celica 3sge would be gen 2
A 94-96 celica 3sge would be gen 3

So I'm guessing gen 3?

 

May want to weigh out the costs of the 5SFE swap to the 3SGE swap. The 3SGE should be direct bolt in for the most part while the 5SFE may require custom mounts. Just something to keep in the back of your head while pricing this out.

 

I personally like the 3SGE over the 5SFE, namely because it is a pretty rare motor in North America, and it's a 4th gen. specific motor over here. The 5SFE is good, but it's still basically a stroked 3SFE. Also the only car I've driven with a 5SFE was a camry with a slushbox, so I may be biased that way as well.

 

both are a direct swap, however you will need to change everything over from the 5sfe. dunno bout the tranny on either engine though. if you do go with the 5sfe just get a front clip from a wrecker that has a decent camry or celica. just rip that thing apart and you got your engine. of course it would be wise to rebuild on both engines. which in all sense means that if you were to do a rebuild and dont care about power at all, you might as well rebuild your 3sfe and not spend the extra time and money for a swap. but thats from a strictly "cheap-skate" point of view.
