7a fe to 5s fe., has it been done? need input. Options

[pipwud]

I'm goin to try and make it happen.

I have been doing a complete rebuild on a 94 celica for over a year now. I put in a fresh 7a Fe engine but have a 5s Fe sitting around my garage. I was looking into boring it out and replacing the 7a Fe. I've also been tryin to look into an awd transmission that bolts up to the 5s Fe, if one exists.

To be honest, I don't k ow what I'm getting into.
New to 6gc. Been reading a lot. Did me good.

Plan on posting pictures of where I've gotten so far. in the process of wiring power doors in place of my manual I had previously. Any input on that would be much appreciated.

And anyone around phx, az?

The same AWD trans that the 3S-GTE uses (E154F) will bolt up to the 5S but it takes a whole lot more than just the transmission to make your car AWD. It's pretty pointless with the 5S, in my opinion.

To go from an A series engine to an S series takes a little bit of work but is very doable. Most people would say it isn't worth the effort to go from a 7A to a 5S, but that's because most of the time when someone asks, they still have to buy a 5S. In your case, since you already have the 5S, I say go for it. I've had both and the 5S is simply more powerful all around. It's worth it if you can do it under $500 or so, and keep in mind that you'll need new axles, shift cables, motor mount, full exhaust, and a few other things for that price.

Honestly its worth it if your not looking for alot more,power an swapping to a 5s now youll be set for better swaps later on
5s an awd is a bad idea tho another guy did that to rally race an found out right away the 5s is way under powered to pull a celica as awd

Youll need new axles crossmember motor mounts shift cables. Transmission wiring harness some exhaust work new ecu an probably a few other things

dont do it. the $$$ to install a 5S-FE even in FWD only does not justify the performance. you might as well drop in a V6 or 3S-GTE

I was noticing that there were spare threadings all around the firewall, shock housings n all that. Considering my model is a 94 st, would any of those threadings be included in the swap or would I have to fabricate all that? And I do have all four motor mounts. When I pulled the 5s Fe, both of the mounts on the cross member looked similar to the 7a Fe motor mounts. Any assurance on that?

What all can I expect to bolt up without an issue n what should I expect to give me any issues?

Can anyone point me in the direction of the guy that did the 5s Fe awd spec?

Random question; the speaker in my door is an 8in. Crutchfield outfits to an 8in, too. Problem is, I've not found 8in speakers. They're all subs. Could I just throw those in? And anyone know where to get aftermarket interior pillars or panels?

I'm filled with questions.

I believe it's just the passenger side motor mount that needs to be swapped out. You could compare your mounts to find out.

I believe 3/4 mounts will bolt up, there is more information available in the stickies. As stated above, you will need the GT trans, shift cables, axles, all new exhaust, and a list of other things.

Marine speakers are available in 8". Otherwise, it's easiest to just fit a 6.5" like the majority of us. There is plenty of info on that in the stickies or, if you really must have subs, click on "Information" in the black bar the the top of the screen. There's a how-to there.

Right on! I appreciate you. I'll compare those mounts. If not, what would I do to get the 5s Fe mount in there?

I could give or take on 8in subs. I already plan on putting a system in the back. If the bass doesn't impede too much, would 8in subs fit right in?

Could you explain 'stickies' to me?

Thanks a lot!

8inch subs bolt right in i have them in my coupe.
Id just get a s54 trans an the mount that are on it an get the gt crossmember an that should get the job done

The swap should be really simple since its a us base car anyway

And how's it sound? The s54 is the manual trans for the 2.2, correct?

That all depends on the exhaust set up you run

Yes the s54 is the 2.2 manual trans

Was talkin about the 8in subs.

[kurt95gt]

Oh lol. They dont sound too bad. They give a desent amount of bass over stock
But if you do it put some of the stick on sound deadening stuff on the inside of the door to keep the viberations down
