6G Celicas Forums

Well said Art.
I don't agree that you'll spend half on a v6 swap, that's just crap.
My 3s swap had virtually no lag and would kill any v6 put into any Celica.

Well, considering the 1MZ-FE is half what a 3S-GTE costs...

My butt dyno and childish grin second this statement.

Yeah I understand that...My room mate has a 1967 Camaro with an LS1 in it with one of those hugh turbos on it...thing takes forever to spool up. Sounds like a jet airplane while it is lmfao

you guys are my heros lmao I can't wait till I get this started I'm so excited. I have the money I'm just trying to do some research first. I was told by my friend Kevin that i needed to do the disc brake conversion. Which I am going to go looking for this Saturday and swap out my transmission to one out of a gt as well. so brakes then tranny then motor....hopefully YAY

Is your friend Soulend, by any chance?

only my ALL-TRAC




if you have a ST then there would be NO POINT in installing a GT transmission. IT WONT FIT!

this is what we have been talking about. 3 of the 4 engine mounts are on the transmission and the GT and ST have different transmissions so the mounts are in different places. if you are going to get a GT trans, thats fine, just dont install it until you are ready to install a 3S-GTE or a V6, and the GT trans will NOT bolt to the 7A-FE engine

lol yes




right right I understand that. I was gona get it and put it aside until I got my motor and everything is ready to be put in.

how the f*** are we even having this debate? 3sgte > 1mz any day

Ok I was told to ask a few more questions:

Do I need to change axels? If so to what I.E. MR2, GT, or ST205?

Can I use the shift linkage from the GT or do I have to use it from the MR2?

Do I have to change my ECU? If so to what?

And something about wiring harnesses for both the engine bay and for the engine?.....

Thank You

1. OEM GT are typically fine as long as your not planning on going over 300hp. I purchased a set of GSP axels (for the GT) for mine that are almost twice as thick as the OEM. They should handle significantly more than 300hp.

2. The MR2 linkages will not work as they're a different length going from and MR car to an FF. The GT will work as long as you use the S54 transmission. If you do a complete conversion to an AWD trans, use the GT4 linkages.

3. You will have to at least use the 3SGTE ECU as well as the 2 bar MAP sensor from the engine. It is recommended that you use a stand alone engine management system though.

4. Wiring harness needs some fabrication. What kinds of fabrication, I don't know, never done one. But there are a few people on here that will do it for you and I see that there is also a premade harness being made now for this swap.

I'm going to take a wild guess and say that you have never actually DONE A SWAP.

All swaps cost money. Take whatever you think its going to cost, and double it because unexpected expenses always pop up and there is lots of hidden cost in these types of things. You could do either swap for the same exact amount depending on the choices you make.

I have, just not with the Celica. All my swaps didn't involve computers and the wiring harness consisted of a ground strap to the starter. The way it should be.

Still when the main part of the swap(engine) is cheaper, that swap will be cheaper.

You are freking AMAZING!


I don't think so I found a full 3SGTE out of an MR2 already. Everything is good on it for $700.00!!!

how do you figure. back that up will ya?


i wouldnt trust that 3S-GTE. and like said before. if its from an MR2 you need to buy a bunch of extra parts.. the alternator is different. the mounts are different. you might need a power steering pump. plus at that price its probably a 2nd gen and we have mentioned what that requires.

$700 for a 3S-GTE, just doesn't sound right. Also why the hell bother with the 2nd gen? More work and less power. If going 3S-GTE get the 3rd gen and call it a day.

I have an ex that owns a salvage yard and it is a 3rd gen motor.



for me getting a new alternator doesn't bother me I need a new one anyways. I also need a new power steering pump because mine leaks.


Plus it's got a super charger on it...so I figure I could probably sell that...so either way I can still make money off of a $700.00 motor.

Supercharger? The only MR2 that had a supercharger was the W10, and that was with the 4A-GZE. That and all USDM MR2 W20's had 2nd gen 3S-GTE engines. Something isn't adding up here.

You're missing the hidden costs. Doesn't the v6 swap require a fair bit of wiring harness work to work in our cars? Thats another 500 Dr Tweak dollars that you can add to the cost of the motor.

Maybe someone else put a super charger on it. I duno. I'm going to go look at the motor. I'll take some pictures of it and post it on here...So you guys can have a field day letting me know the f*** it is.
