So far there hasn't been a ton of problems, or anything that was really causeing problems. About one of the biggest clearance problems is the proprtioning valve for the brakes.



And the shifter is a little far forward, so we will have to cut the whole out, and move it forward.



But let's hear everyone's input, and opinion's.

wow thats so cool though, you can really truely see how small a 13b is when looking at all the space the 7mgte takes up



but - gasp - only 2 motor mounts? albeit theyre beefy as all hell...

Yeah, you can see were we had to cut the fire wall and set it back 3-4 inche's, because the front pulley was sitting in front of were the radiator should have been.



Also on RX7club, everyone was gripeing over how I messer up the weight balance, and just for everyone the #2 cylinder is right in the middle of the front wheel's, so the weight balance hasn't changed that much.








but - gasp - only 2 motor mounts? albeit theyre beefy as all hell...




Damn shippy, need beefyness to hold a motor that was giveing the engine lift trouble on the 1,125 lb. lift point.

blashphemy! its a white t2! you should be cutting up the red ones



mike

1Revvin7 08-28-2003 05:22 PM

Why did you do it to a t2? I can see an n/a....



But anyhow, its always cool to see custom work. How much wieght has that added tho? Polish that biatch!!!

wanta be boosted 08-28-2003 05:36 PM


its a white t2!




Uhhmm that has what to do with anything? It will probably end up a nice dark green, or maybe pearl white, once I get everything done, because the paint is horrible, and is not the original paint. Although it was white from the factory.








Why did you do it to a t2? I can see an n/a....




Because a TII is what I had when I got this idea.



And the TII has a stronger drivetrain (what's left of it anyways), also it has stiffer suspension, and I don't plan on buying new suspension anytime soon. Because the 7MGTE didn't push the front end down hardly any when we set it on the motor mounts.

FrestyleFC3S 08-28-2003 05:58 PM

cory ... mike was saying white is rare....and red you see every direction you look in

wanta be boosted 08-28-2003 06:13 PM


So why did you do it?






Because I got tired of playing, what wrong with my rotary today.



So I decided to get an engine that will run for 250,000 miles with no problems. And an engine that has more power, and torque.





Yes, it's treason I know, but hey I like reliability, and potential for 750 HP. https://www.nopistons.com/forums/pub...1047683894.gif

FrestyleFC3S 08-28-2003 06:30 PM

btw - its heavier, and while it has more power and torque than ur S4 engine, its got less power and more torque than the S5 engine

I can understand where he's coming from, I've played the "whats wrong with my rx-7 today" game, but it had nothing to do with the engine. It usually had to do with the widespread drug use in the 60's-70's resulting in the 80's engine management systems like the one on the FC. It's easier to put a haltech on a 13B than swap in a different motor, and you stop playing the guessing game afterwards. But engine swaps are fun, I hope the reasons he stated are not the only ones for this swap. Either way, it's cool to do stuff that involves fabrication and hasnt been done by every other person with a FC. I give him props regardless, it'll probably be less problematic than a *stock* FC. Though I don't know **** about the engine management of the supra motor, if it too is from the 80's w/AFM then it's just replacing one headache with another.

I agree...

wanta be boosted 08-28-2003 08:08 PM

No that is not the only reason I wanted to do this swap, I also wanted to do it because I love the supra but hate the weight. And the potential for 750 HP is a huge perk.








btw - its heavier, and while it has more power and torque than ur S4 engine, its got less power and more torque than the S5 engine




No not quit, the supra turbo STOCK has 230 HP, and 250 torque, so it's a gain over S4's/S5's.

Racer X 08-28-2003 08:12 PM

Cool.Too bad you butchered the firewall tho.

RussellTT94 08-28-2003 08:16 PM

very cool swap. a friend of mine has a mkII supra with a 7m in it. http://wsbf.net/cowgod/photos/2003/index.p...815-new-project

wanta be boosted 08-28-2003 09:20 PM


Too bad you butchered the firewall tho.




How else was I supposed to get it to fit?



There is no way that it would have sit in there with a radiator without cutting the fire wall.





Also it helped the weight balance by moveing it back.

roadkill669 08-29-2003 03:49 PM

Looks pretty good. But, why. Thats butchering a great car. We have a shop MK3 that reaches the 300hp mark and doesn't even compare to a RX7. My RX is probally around 210 and it is so much smoother, revs better, sounds awesome (nothing beats the sound of a rotary). Why didn't you do a 20b swap, or a 26b (soon i'll build it). I can understand the whole more torque thing, but the motor mounts in a RX weren't designed for torque. I would bet that the 7m would tear those things apart. But what the hell do I know. I'm a MR2 person that drives a T2 (and loves it https://www.nopistons.com/forums/pub... ).

wanta be boosted 08-29-2003 03:58 PM

That's why I'm useing mazdatrix compitition motor mounts.








My RX is probally around 210 and it is so much smoother, revs better, sounds awesome




I can't believe that!!!



My brother's MKIII NA, revs smoother than any engine I've ever heard, has such a mean growl at any RPM over 3,000, and has an awsome idle.



Now the last rotary I had on the other hand, reved very nicely (like every rotary), sounded like a jetsons car/weed eater, and has NO idle. But that was just my car.






But, why. Thats butchering a great car.




I thought it was like breading new life into a good car to make it better. I think it will be SO MUCH BETTER than the stock TII. But who knows.

BigTurbo74 08-29-2003 04:18 PM

Looks nice, im glad your not like the local guy that v8 swapped his na fc, he'll bash rotaries any chance he gets.

setzep 08-29-2003 05:54 PM

fit under the hood?

The 7M-GTE is a pretty bad ass engine but watch for a blown headgasket. My friend and brother have been in to these engines for a while and have came across that problem.

What EMS will you run?

wanta be boosted 08-29-2003 06:33 PM

Yeah, I didn't really want the podunk, hilly billy, bastardized car. And I still like rotary's, I just wanted this a little more.








fit under the hood?




Acctually yes, but only with a **** hair of clearance, and that is after cutting some small piece's off of the hood. But this is also a TII hood, and the timeing belt, and timing belt pully's are acctually up in the scoop. So it worked out good.








What EMS will you run?






Well for now, until I get the money to buy a stand alone ECU, I'm going to use the stock ECU, and all the stock electronics.

rx7_re 08-29-2003 06:52 PM

uhh, i give you props for doing it but i look down on you for just giving up on the rotory. https://www.nopistons.com/forums/pub...1047683607.gif



Anyways like I said, good work on it though.



I do have one concearn. Its not the weight, its where its at. Look at how high a lot of the weight on that thing is. Then go look at where a shortblock sits in one. You'll get the picture.



Good luck reguardless

wanta be boosted 08-29-2003 07:18 PM

I know what your saying, but the supra engine's are tall engine. And there is no way I could lower it anymore without makeing a whole new sub-frame for the front end, and relocateing the sway bar, and rack and pinion. Because the oil pan is about a finger's width away from the sway bar in the frontf, and then just a LITTLE bit farther away from the rack and pinion. And even if I made a new oil pan I could only lower it, 1/2-1 inch at the most.

The headgasket doesn't get torqued enough stock thats why they blow easily.Supra guys say to add 20 ft. lbs to the factory torque spec to prevent it from blowing on you.If you blow it that way then you'll need a copper headgasket.A way to upgrade and avoid the stock fuel cut setting on the 7M is to run the NA cams on it.The cams allow 11 psi of boost before needing a fuel cut defenser.

I'll get some pictures of the tranny mount once my brother finishes seem welding it.





But for the most part it is finished, and it is a K member that will be welded to the frame rails of the car.

OK finally some pictures of the K brace.



And it will be welded in between the frame rails of the car, and will bolt to the tranny.

wanta be boosted 09-16-2003 03:38 PM

Well, I finally got my drive shaft made, and it fits like a dream https://www.nopistons.com/forums/pub...IR#>/smile.png





Now the last big thing I have to buy is the clutch (the old one was shot), and I found one for $350 bucks, and it is a triple disk clutch. So it should be fun https://www.nopistons.com/forums/pub...#>/biggrin.png





And then we get to wire up the ECU, and try to start her.

Dramon_Killer 09-16-2003 04:35 PM

a) you gave up on the rotary and you butchered a t2.



b) you butchered a supra and tore its heart right out.



Worst of both worlds. I'm disappointed in you.







lol jk man actually i think thats awesome. It's always nice to see some custom work. And by custom i mean not just a v8 swap.

epion2985 09-16-2003 04:38 PM

want to be boosted, I see you see my dilemma here so I was going to ask you for some advice. What would be a good engine to drop in to an fd. I am looking for a v6. V8 are just a little to big for my liking. I am looking to make about 500rwhp. And I dont want to spend years putting it in so not something outrageously difficult. Any suggestions?

wanta be boosted 09-16-2003 05:00 PM

If you MUST have a V6, I would go with a VG30 twin turbo. Those are the motors out of the new style 300ZX's, but you would have to buy a front clip, because they aren't near as easy to find as say the 7MGTE. And with a turbo up grade and supporting mods, you could be running 500 HP at the wheels pretty easy. And it would fit length wise pretty easy, but the width might be a problem, because we have a 300ZX body (shell), and that damn thing is wide a f#ck!!!! So I don't know about the width. If you are seriously considering that swap I would be asking questions on the 300Z forums first.





But if I were you, and I had the money, I would go with the 2JZ, a 7MGTE, or any other inline 6. They ARE the smothest running engines you will ever come accross. And that is because whenever wheight is being throw to one side of the engine (whenther it be up/down, or left/right) there is always weight that is counter balanceing it (in the exact opposite direction). And they are VERY tough engines. They will run for 200,000+ miles stock with no problem. They would give a honda a run for it's money on reliability.





But there is pretty much no engine that you can't put in a car. If you have the talent and the money, then it can be done.



But right now I have about $700-800 bucks in my swap (I don't remember spending that much, but I know I have). And all the money spending will be complete once I buy the triple disk clutch ($350 big one's), and an AFM. Well, and I also have to build an exaust system, so there is another couple of hundred. And then I will have completed my swap with under 2 K, but it will be a pretty much bone stock 7M. And probably able to keep up with a stock 3rd gen without a strain. Because turbo supra's were very respectable even though they were 3500 lb.'s And this is like shaveing 1000lb's off the supe. https://www.nopistons.com/forums/pub...1047683473.gif





Anyways, if there is a motor, or a type that you like, and you can afford it. Then put it in there.

Have you ever even driven one!!!! https://www.nopistons.com/forums/pub...IR#>/angry.png



By the time you finish the swap you can have a RELIABLE rotary FD that puts out 500whp. Stop bashing it when you dont know **** about **** man...
