So Ive got a project in mind and its kind of a dream Ive wanted to do for years. I want to put a Bridgeported 13B single turbo in a SN95 mustang. I just picked up a clean 98 V6 chassis for $500. Ive been looking online for a motor/trans combo. Looks like $2500 is about average for a decent FD 13B rew with trans, ecu, sensors, wiring, maf, & the whole 9 yards.

I can weld enough to make engine and trans mounts. Driveshaft will have to be a custom job.

I have this vision of a clean, slammed SN95, but with a taste of JDM. Like fender flares, Work Equip look-a-likes, but still use dual exhaust pipes, keep all the mustang badges...ect stuff like that. It looks great in my head. Not build it to be a super powerful race car, mostly just something fun to drive to shows and occasionally drift.

Its a really pretty blue and the body is in decent shape minus one little rust spot on the rr quarter panel. Cant wait to get this project going. Any positive thoughts and advice/recommendations is very welcome.

You definitely have a good shell for the project. If i were you, you want to bridge the engine so you'll need an aftermarket ECU anyways to get it running right, i'd just be looking for a motor and trans and make yourself a engine wire harness

Another idea too, you have 2 options with the trans, you either get a ford trans and make an adaptor plate, that way you keep the original driveshaft and shifter location, or as you said, make a custom driveshaft, but the shifter location will probably be in a way different position, the choice is yours

Yes I was definitely thinking bridgeport and single turbo. Would I be better off going with a S4/S5 combo, or jump to an FD S6?
Whats a good user-friendly ECU/standalone that I could use? I have heard mixed opinions about megasquirt. Whos else is a good system to go with? I am decent at wiring but have never wired an entire engine before. Mostly fuel pumps, signal wires and plenty of lights.

S5 is pretty much the same as s6, i believe the ports are slightly different with s6, but if your gonna bridge its not going to matter much, you biggest limiting factor will be the intake and exhaust, bridges love to BREATH, and love the extra petrol to go with it

Ecu is entirely up to you, the biggest factor is if YOUR going to tune it or not, if your not, start making phone calls around your area and find a tuner and ask what they tune, that is what should make you decision

Awesome :-) Usually people put mustang engines in RX7's, nice to see it the other way around for once.

So futher looking into engines and things I would need, Why in the world have prices sky-rocketed for 13B turbos?!?!?! Uste to a guy could pick one up off ebay for around $1600. Now theyre around $2500. Not to mention it would be a good idea to have it rebuilt and ported, and possibly a single turbo conversion and fmic. So just to get a motor some-what properly set-up is going to be well over $5K, not to mention how much fabrication to get everything to work in this SN95 chassis...feeling a little dis-heartened at the moment

I don't suggest a rotary in a mustang the same goes for v8 in a rx7 bit to each his own. If you live in Central Fl I know of a place you could get them for about 1600.

Fabrication...:
-Modified/Custom Trans Mount
-Custom Engine Mounts
-Run Return line if not already there
-Custom hose to brake booster
-Custom Mount for IGN coils
-Haltech/Microtech/Megasquirt
-Wire a separate engine harness
-Adapt battery harness to supply power to starter
-Find way to make speedo/tach work with 13B, or aftermarket Speedo with GPS and aftermarket Tach to 13B
-Find rubber hoses to make match with Mustang Radiator
-Custom driveshaft from local driveline shop
-Custom downipipe or modded downpipe off an existing setup all into a modified fleabay exhaust

I see sheetmetal, some thicker steel for the trans mount, and some welding, and (if willing) some soldering for an ECU, wiring for harness, and a little ingenuity. Nothing crazy. Yes, probably about $5K if you do it yourself, but not bad in comparison to some of the full builds on here. You could always build the motor yourself, source your own irons and rotors, or even do a 6port turbo, which have been putting out decent numbers of late. Couple that with a decent used turbo setup and a used turbo 2 trans (which are stronger than FD trans anyway), and youve got a custom built monster on a budget, then as budget allows, upgrade your turbo and exhaust, go from there.

I like this RotarySN95 idea, cheap RWD rotary coupe.....words that are harder to put in the same sentence.

Do it. Or space it out as budget allows. If you need 6port irons, I got you, on the cheap, just PM me.

I would suggest the Turbo II trans as well. They use your "push" type clutch instead of the pull type in the FD. This makes your clutch a little cheaper as well.

I believe they make T5 to 13b adapter plates, so that would probably be wise instead of going with an REW trans at the very least.

How about rx7 with rear seats. I have a 02 mustang gt 4.6. Also a fd 13b. Why not a 2nd gen na with back seats. It is just a little tighter than that mustang back seat. Just asking. It will diffently be different if that is what you are going for

Been A crazy couple of months. I'm in the middle of a career change and buying a house. Thank you everyone who chimed in. This thread is not dead!!! Just put it on pause for a little while. The house we're moving into actually has a 2 car garage (My dream come true) So this will be my Sanctuary and Awesome build laboratory! Lol.

I finally got to put a little work in today to the stang and got the nasty old interior out. Cant wait to get into my garage with all my tools and start the carnage.

To re-cap, someone was saying that the S5 T2 motor is perty much the same as a S6 FD's motor? Also, I believe my car had a T5 at some point, but I got it with no transmission. Just the motor. Oh and no flywheel or clutch either. I literally bought it for the body. Would a T2 trans be better or should I source out a T5? I cant wait to really get this project going

"Would a T2 trans be better or should I source out a T5?"

6 of one, half dozen of the other. Go with what fits the motor, will make the swap a little easier.

So we're all moved, house is coming along nicely, and I even got to finally pull the motor out of the mustang a couple of weekends ago. I did find a place in Quebec, Canada that sells JDM engines and T2s for around $1600 so when money allows I might be going that route. Unless any of you have a good deal on a 6port NA motor with T2 trans???

Is Kevin form Rotary Resurrection still around? He rebuilt the motor in my old FC several years back and did an outstanding job. I was considering him again for this build when the time comes.

Question on axle/diff: The V6 mustang comes with a lame factory 2.73 final drive with open diff. If I added like a 4.10-4.30 and welded the spider gears would that hold up to a 350whp rotary you think? I would love to upgrade to a 99-up cobra IRS setup, but thats another $1000, but it would help it handle like a dream.

I appreciate all the help and info folks! Keep it coming. I get a lot of nay-saying with my other car people, but I always come back to my Rotary family.

The SN95 has an 8.8" rear that is bomb proof with the right parts. Just get a GT rear, or rebuild yours with new gears and a locker from summit racing or something. I never would weld spool gears. It makes the car drive like crap and only good in a straight line.

Gilgamesh

Yes he is still around, although he is not on this forum.

All of these RX8 rebuilds are keeping him busy.

I actually live really close to Banzai racing, but they're a LOT more expensive and a lot less personable (atleast that was my personal take). I had them as a customer when I worked at Napa. I'm sure they do phenomenal work. Their website is impressive.
