Okay so I have a 98GT with a 5S-FE in it. I'm looking to eventually put some power in it or do an engine swap in the future. For now I am sick of going down the high way cruising at almost 4K rpms.

I have read a lot about the E153 Tranny. I also was wondering if anyone has done an S51 swap as well.

Basically to summarize what I think i know..

For E153:
ST205 Mounts, Cables, and Linkage
Axels- I have seen a lot of combos, i know if its out of an MR2 i need the same year inners, but i have seen that the E153 is in certain year solaras too. So could I use those inners, and for outters i see the 91 Camry seems to be most readily available.

What is the Mr2 year bracket, 90-95? And anyone have any info in doing a S51 or if i even should consider it?

Thanks a lot everyone!

you dont want an e153 attached to a 5s. the gearing is WAY to long for it.
what is an s51?

I believe its a Camry transmission. http://en.wikipedia.org/wiki/Toyota_S_transmission

ya its in a camry tranny and the ratios and final drive seem like they might be better for highway at least i think. the ratios are still a little confusing. thanks manny for advice on e153. anyone got input on the s51?

I just looked at the Wikipedia page. Given that we all know what the S54 an stand up to and how similar the S51 is to the S54... why would you swap? The S54 is bulletproof. You'll never have problems with it. That's like swapping a 5S-FE into your ST. You CAN do it, but it will cost you money and give you no real benefit. You'll lose some acceleration with the S51, but you'll have a higher top speed. So yes, you MIGHT be able to do 140, but it'll take you forever to get there. I would stay with your S54. You might be sick of cruising at 4k, but most low-power four cylinder cars are pulling similar RPM's.

You have a manual tranny and you're at 4k on the highway?
I have a auto tranny and when I'm cruising at 80mph on the highway, I'm just above 3k, doing 65mph it's at about 2.5k-ish.
You must have something wrong with your tranny lol

you will do 4k at 80mph on the highway mike, i do it with mines and you will do it with ur tranny sway as well lol

the auto tranny is different, isnt it a 4 speed tranny? so the gear ratios are different then on a 5spd

a little blurry, but i just want to confirm.
about 84mph @ 3.2 while cruising on the high way.

there is nothing wrong with his tranny.
your auto has longer gearing.

well thanks for all the input everyone. im still kind of on the fence so we will see what happens i guess lol.
