does anyone know if a FD trans will fit in a FB or what mods it takes to do it????

The short answer: Not so much.



The FD trans is supported by the PPF, and not by a crossmember underneath. You would have to work out a totally new mounting scheme



The long answer: With enough time and $$, you could totally do it. It would just be a major bear.

A FC Turbo II tranny would work better.....

well ijust picked an fd drivetrain and was thinking of doing the trans with the motor also, i was kinda thinking about doing the 2nd gen front subframe swap also to accommodate the stock styl fd motor mounts.Let me know what you think. What is a pdf I am not third gen literate https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

PPF = Power Plant Frame.



Rather than a rear tranny mount, 3rd gens have a C-section aluminum casting that connects the rear of the trans to the front of the rear diff, then the diff is mounted to the body.



And again, it seems unlikely that a 3rd gen would have good gear ratios to work with the power of the NA 1st gen.

well the power will not be a n/a first gen it will be a built fd motor and turbo car

if you have a gslse i think the mounts will be the same. i think all of the 13b mounts are the same.

the gsl-se has a front mount style motor mounts where the third gens are mounted off the rear

no, the 12a motors are that way, the 13bs are all the same

well since my car is a gsl-se i think i know where the motor mounts. It mounts just like the 12a motors do. I am not trying to start forum wars but it mounts just like any other first gen motor (gsl-se). The third gens mount on the rear iron if what i saw last night is true. It will mount right about where the idler arm mounts on the passanger side frame rail

pre-85 rotary engines , 10a,12a, and 13b mount with the bracket bolted to the front "timing cover", after 85 (2nd gen) motor mounts are bolted to the intermediate housing. one bolts up mid oil pan and the other on the opposite side with studs that stick out of the intermediate housing next to the engine water drain 14mm screw and is held with 17mm nuts. Pic below is engine out of my 80 13b first gen. White car is a 84 GSL-SE 13b fueld injected, notice how they both have the front mount bracket just like the 12a. Anybody have pics of a 2nd gen engine with mounts.

Hey thanks for the pics jgarza77 it helps out. Did you get your 3 core rad yet? I blew up the gsl-se motor so i found a built third gen motor i am gonna try to get in it using factory mounts for the third gen and am considering the 3rd gen trans too got any input on that

hmm. i was under the impression that they were the same bc anytime someone wants to put a 13b into a 12a car they have to use a 12A front cover. if what you are saying is true, which m not really debating bc ive never really paid attention to it on my fb5, then a swap into a 12a car would be able to be done with the front cover from any fb engine

if memory serves me right, if you use a 12A turbo front cover and water pump it should ease your installation a bit, because the front cover will have the place to bolt the front motor mount bracket to your FB and it has the oil line to the turbo and so on, you are going turbo or are you going n/a?

Using the 12a front cover on a 2nd or 3rd gen into a 1st gen greatly reduces installation problems, trust me on that one. And if you use Racing Beats, front motor mount bracket it will keep you from bending welding and rigging your motor to fit. Also when using a 2nd or 3rd gen into a 1st gen the oil pan clearance needs to be looked into and the easiest way to solve that is to use the GSL-SE pan.

Aren't the S4/S5 TII trannies stronger anyways?



ALL the FB motors mount the same, that is, using the crossmember front cover thingy. Yes, thingy.

You not only need an FB (GSL-SE or any 1st gen model) oil pan, but the oil pickup as well.

My only problem with running the first gen cover is the oil pan i would have to build one. I want to stay with the crank trigger setup on the 3rd gen motor i also got the complete harness so i will be running the aem pnp system to runn the motor with electric omp and everything just a single turbo conversion on the motor

had to read your post a couple of times, sorry.......got the 3 row it works great, I took a saw to the old one and it was trashed, sorry no pics. I have never done a 3rd gen engine and tranny swap using the stock mounts of the 3rd gen so not much input on that but if your present motor is a GSL-SE w/turbo, you should be able to use the front cover, mounts, and oil pan from your SE motor on the 3rd gen motor, not sure about intake bolt pattern though. What exactly are you planning to install? you going with the whole 3rd gen engine setup including twins?

I'll have to look into that, I know my SE pan bolts right up to the 2nd gen 13 but not sure about 3rd. Ive seen the crank trigger setup on a 1st gen on a car at Rotary Performance in Garland (rx7.com) but would have to shoot Ari an email and ask. Chris there is very knowledgable as well and would be glad to lend a hand.

shoot some pics of your present setup and of the engine going in so I can get an idea what you getting into, Ill get with my fellow rotorheads and see what we come up with or who's done it and we can compare notes.

Well I found a third gen project car that some one started to build got like 15k into the car then it got vandalized so they gave up on it. If i already didnt have 20k into my car i would just build the third gen but too much invested in my car to give it up. I bought this project car for the built Pinapple racing motor and the intake maninfold the transmission,wiring harness all the running gear but the rear diff. I split the cost of the project car (3rdgen) with a buddy of mine that wants the body and interior for LS-1tt car. Got all the other parts i need for the full swap from the third gen to first. I am also gonna do the second gen front subframe swap so i have the room to make motor mounts. I fabricate daily and i really enjoy the challenges of this kinda work. The motor has no turbo system on it right now the kid sold all of that before i could get it from him, everything is ceramic coated that should be water pump housing,t-stat housing the rotors and housings with the irons,oil galley mods are done cooling system mods are done too this should be a really bad ass motor I talked with Rob from Pinapple and he said since it has sat for awhile to go into it and make sure all the apex and side seal springs are still okay and that there is no rust but i didnt know the motor was ceramic coated till i went and looked at the car and got shown the reciept for the motor. Performance clutch all of it. But i got some sponser ship in the clutch department so i will not be using the one in the car. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

5 lug conversion, drilled & slotted rotors, 2nd gen 13b, with turbo Im feeling all hot and bothered and so jealous.......man that looks good, what size wheels are those?

[attachment=32250:attachment]

well if i do the front subframe swap i will be selling the 5 lug conversion for the front if you might be interested in it i have 300$ into it i would take 200 plus shipp that will be the strut housings and spacers with caliper brackets if you need calipers and rotors we can talk i got access to a buch of second brake parts

let me know after you do the swap, I got so many 4lug wheels laying around right now, that if I went 5 lug they would be rendered useless and my old lady would probably freak If I told her i was buying more...........I need some time to throw more on ebay.

well you couold run the four lug hubs and rotors on the strut housing and it should be fine so you could run you four lug stuff if it is the large four lug and if it isnt i can get you some big 4 rear axles i think
