6G Celicas Forums

So I drove the beams for the first time since the new fifth gear yesterday. Went to New Jersey and back on one tank of gas. I did not try to save gas, I drove normally, about 80mph most of the time, some minor traffic, downshifted to fourth and played around a few times. Filled it up this morning and it was 34.1mpg. We have gotten that before while driving out to the Midwest meet last year but we were trying pretty hard to do that. Next time maybe I'll try for best mpg but that's hard to do with the beams, it just wants to play.

On a side note, I was actually a little against this mod cause I really don't drive on the highway at all and I was apprehensive about opening the tranny for something I didn't see a need for. But Dustin does a lot of highway driving and he wanted to so I went along with it. That being said, after driving the car, it's pretty f-ing awesome! It's like a totally different car, so calm for cruising but all the fun still available to you. I really could not think of a downside yesterday.

Thanks a lot for that information. Finally someone found the solution to our problem. I always wanted to add a 6-speed tranny box to my celi. Going at 4krpm at 80mph is no fun with the engine screaming. Now I'll have to wait until the clutch wears out

Actually the 7th gen with the 6spd tranny is a little higher rpm than the beams is now.

looks like a lot of work for such a minimal drop in RPM's. Is there a bigger 5th gear out there that could drop it significantly. Or a 6 speed tranny that would fit a 5sfe engine. Just saying...

Looks like a good upgrade for top speed for the gt4.

im going to do this when I put the V6 in Amy's car. Ill add pics then. Ill also take a before and after pic of the speed and RPM like Dustin did

Does any one know the full gear ratios of the camry compared to the gt-four?
I personally think all my gears are too short.

Ray, this basicly uses the same 5th gear that's in the e154f. So no improvement for you guys.
we did the swap on jenns car a month or so ago, huge imrovment.
I'll post more about it and pics when i have more time.

Oh thats a shame. Ive always felt that im shifting like FATF endlessly and when I build a new more powerful engine its gona be worse popping through the gears in town.

I noticed you're not using the plate that goes under the front engine mount there... how come?

It's a front mount from an ST.
The same as a GT but no awkward plate underneath.

Interesting that they're interchangeable like that.

Awesome write up! thank You Dustin.

Question: I have a 96 ST with 7AFE (I have a manual transmission, C52? Not sure). Can I do this swap on my gearbox?

I do a lot of highway driving and it stays close to 4K RPM at 80 to 85 MPH.

Thanks in advance.

just s54 tranny..

Are you saying that this swap is only doable on S54 and not on C52?

that is correct.

I havent confirmed this yet but i have the ability since i have a 7A and a C60 (7th gen 6 speed) here. if the C60 bolts up then you might have an awesome alternative for the ST

that would be a very nice. Please keep me updated. I would love to have a 6 speed in my ST.

the other question I have is Will s54 fit a 7AE without modification or axles are different?

The C60 from a Celica or s54 won't bolt onto a 7AE.

You Might be able to use a C160 used on the 4AG

actually a C60 will be close
