Cool TII into 85 gs.. is this everything?

Do some research..

https://www.rx7club.com/showthread.p...ght=chronicles

https://www.rx7club.com/showthread.p...light=13BT+gsl

yeah, there are tons more. Show me some of the better ones that I might have missed?

I know that in the archives there are some that show how to mount the TII tranny. I am planning on getting a 'se gas tank, a better fuel pump, new fuel lines.

I am not sure of the drive shaft.. would the tII drive shaft work?

In other threads that I have posted you might have read how I am taking a 13B apart and how I am going to build a 13B 4 port. to sell to a friend (maybe.. now

I have heard that I will need some kind of crossmember to support the engine? even with the 13B'se front housing?

I am going to do this swap myself, well as far as I can get anyway. I don't have all the tools that most do, so I will be buying tools as I go. I need to start this soon (within the next month or towards the end of it) I know I am going to be running into times that I am just going to flat out of cash or out of knowledge. I hope to seek some knowledge (and cash ) from everyone on here.

I hope the freaking engine doesn't fall on top of me :/

What am I leaveing out?

.:please post something useful:.

just start to do it...and use these as references when you get stuck...your going to need a oil pan of a 12a and a different rad...suggestion is an intercooler as well...every post on a 13bt swap has its points that another misses...you sort of got to pick and choose the best 2 or 3...however there was a really thorough one done within the last year or so...just can't remember who did it...

Oil pan should actually be off a 13b GSL-SE

what I would like to know is the drive shaft.. can I use a t2 drive shaft into the rear end of the gs from the t2 tranny.

I really just wanted everyone to add there links to this one or something like that. All the searches talk about 13BT into a 'se. The ones that place the t2 into a non'se useally don't have all the information that is needed.

I am looking for: 1. where to position and support the t2 tranny on a gs and 2. I can use a drive shaft thats not custom?

more question like omp lines and stuff.. well I can search for those when I have time. I just need placements for the above items.

You can use a TII shaft. IIRC you have to lengthen it. Take it to a shop and have them cut, re-weld and put a new inner core in it.

As for the IC goes I did a writeup in the last couple months or so. It was using the massive Ebay SSautochrome one. Sonce then I have changed my setup but it it a proven setup and should work perfectly.

I have read that the 12a front cover will fit. However since I have a SE I cannot confirm this.

OMP, I am blocking this off. One less thing to worry about IMO.

As for the Tranny get a S5 and make the mods so that the shifter sets in the stock location. Then take the upper portion of the S5 mount and use that with your SE mount. I think that 12a's are the same. But I am not exactly sure. Make a spacer and set it between the 2 mounts. This will give you the correct pinion angle. The spacer should have a thickness of approx .5".

Other little things will be turbo flywheel, and TII starter.

Hope this helps...

ok.. is that a mispell or something? whats IIRC?

unlike others.. I am going to buy a complete t2 with tranny, ecu and wiring harness.

I am going to strip the GS that I have tomorrow and this weekend as well as buy a new camera. I am hopeing to take as many pictures as I can so that someone can help me put together another one of those t2 into 1st gen sticky thread.. lol

1. start with as a complete system that you can.. engine, ecu, wiring harness.
2. Get a 13B 'se front cover OR MAYBE the 12A cover.
3. drill out the plug under the omp for a fitting for the turbo oil return.
4. prep car (remove old engine, install fuel lines, pump and arrangements for either a 'se gas tank or the "cup" that goes into the 'se gas tank.
5. Route the ecu and wiring harness plug as much as you can...

6. mount the engine and tranny, also install the remaining drive line components. Will the t2 shaft be a direct fit?

7. conenct all components to the engine..
8. pray
9. place key into ignition
10. PRAY
11.turn key to start position.

what else did I leave out before I go and show this to my brother, forever to be known as "the most sceptical *** I will ever know".

If you are using the stock ECU you will need to connect the OMP. its been posted before but I will repeat, you need the 12a front cover, then have the mounting pad for the OMP tigged up and redrilled for the new bolt pattern of the electronic OMP this is a 40 dollar job at most welding shops.

the none SE front motor mount will work fine, you need to slot the holes backwards about 1/2~3/4 of an inch and that will take care of the mounting.

lastly I answered two of your quesitons, now I am going to be a little crass....Freaking research it.

PM the people that have done this, don't ask for a how to ask for a few specifics when you cannot find it in a through search

I wasn;t planning on useing a 12a front, I got a 13'se front. I didn;t know anything about the omp because i was going to premix. I don't know about the fact that you MUST use the electric omp when useing the stock ecu.

Lastly, I didn;t make this thread because I didn;t do research. I did it to verify everything that I know. The more people post things I haven't found while SEARCHING the better and more complete my install is going to be. Thanks for posting, please post other stuff, no matter how small. I don't want to forget something and be stuck dead in my garage.

Relax...there is tons of information here on the board. We are only trying to help. Bur I agree with Kenn all the small little things that you have asked have been in threads. Spend 6-8 hours more and read all the threads. Make notes if you have to.

I think that most of the people here are more than willing to help you out just make sure that you have done all the possible research that you can.

IIRC... If I recall correctly.



I am going to strip the GS that I have tomorrow and this weekend as well as buy a new camera. I am hopeing to take as many pictures as I can so that someone can help me put together another one of those t2 into 1st gen sticky thread.. lol

There is no need for another one of these. There are too many already. Read/re-read.

1. start with as a complete system that you can.. engine, ecu, wiring harness.
2. Get a 13B 'se front cover OR MAYBE the 12A cover.
3. drill out the plug under the omp for a fitting for the turbo oil return.
4. prep car (remove old engine, install fuel lines, pump and arrangements for either a 'se gas tank or the "cup" that goes into the 'se gas tank.
5. Route the ecu and wiring harness plug as much as you can...

6. mount the engine and tranny, also install the remaining drive line components. Will the t2 shaft be a direct fit?

7. conenct all components to the engine..
8. pray
9. place key into ignition
10. PRAY
11.turn key to start position.

No offense but you make it way easier than it sounds. There are tons of small little things that also tie into the project. If you have an extra 3-4k dive right in and see where that takes you. If you have questions along the way just ask!

My other post also said you NEED to modify a TII driveline.

Good luck

Oh, just another side not. If the OMP is not connected to the ECU it will throw a error code. This is why it needs to be connected. You can still run premix if you wish. Just neatly wrap the OMP under the dash so that it is out of harms way.

screw it.. I am going to post what advances or setbacks happen to me here

its freaking cold. I don't think I can take it.

I disconnected everthing attached to the engine. I couldn't get 1 tranny bolt off. the wrench sliped and knocked me in the head. I had to go to the emergnecy room,, they patched me up with some glue. It was only a 1" split.. lol freaking ****// it happends when you mix oil, antifreeze and beer. I ahve hd it. No more oil and antifreeze for me. Well anyway.. I don't have a heater and the cold gets to me quick. I am jsut going to take the whole thing out.. the tranny and the engine. I was only planning on takeing out the engine.

tomorro...

so.. it!

I'm pretty sure that I have read in some of the threads that you can use a stock -SE driveshaft; as long as you get the TII knuckle on the tranny end.

In other threads, however, I have read that you need to shorten the driveshaft when using the TII tranny. You also need to mod the tranny to fit through the stock shifter hole.

Atleast, I am pretty sure that I read that information correctly. I'm sure someone will come in and correct me, though.

well i took everything out just like i wanted. engine, radiator, that thing for the air conditioner and tranny. I broke some wires,, snapped some screws,, bled some blood, drank some antifreeze and oil. Well the hard work in the freezer is over. I took some pictures but the freaking camera fell into a bucket of oil. I need to get another camera and take better pictures. I want to show ya my car, in detail. The car has some rust on the chassis and the rocker panels have rust holes. Worst of all whoever owned the car before me apprently didn't think much as to where to raise the car. It looks like hell underneath. I need to replace the rear axel as I was doing donuts and smashed against the curb and bent to axel up. Not sure thought, I need to raise it and pull it apart.

I'll get a new camera and take pics, I am going to do a t2 engine swap.. I don't want to start off with a chassis thats going to give me more problem down the street.

How much and what do I remove out of the engine bay to get my rx7 gs ready for my TII swap.

Never heard that SE driveshaft trick. I will have to swap the parts and try it out.
