I have been looking at 944 and other porsche transmissions for sell on ebay.
I am also aware that to put a rotary a beetle there is a bellhousing adaptor.Which is a porsche transmission so on and so on. what be possibilities of making a rear engined fd? please dont say alot of money.i know this.my post count doesnt for my knowledge. The differential is already built into the porsche transmission.You could create some mounts to hang the transmission from the rear crossmember.Move the gas tank up front.The radiator would also be up front no blowing hot air directly onto the engine.Also being able to hold more coolant and longer tubing for more cooling. Of course there would be the intercooler cooling issue which would be handled later. What are your comments on this idea as far as handling issues.Or would there be any if done correctly. I mean hell if im going to have my car completely broke and ripped apart then rebuilt. Why not try to do something different. |
What is the point when the car already has 50/50 weight distribution? You would screw up the handling balance.
|
yeah it wouldnt handle. Most Rear engine cars have the passenger compartment very close to the front of the car. the FD has a nice long hood to fit the motor, and leaving that empty would be a very bad idea. all the weight of the car would be in the rear.
|
umm why wouldnt it handle?nsx's are one ur top handling cars and so are ferraris and lambs.they all have rear engines. up front would not be empty.
you would have a gas tank,radiator,oil coolers,my ecu. the 911's or gt2's are great handling cars and have the passenger compartment area in the middle like the rx7 does. it still sounds like an option to explore. |
i dunno if theres enough room between the back of the drivers seat and the diff to fit the motor

What advantages would the mid engine in an fd have, or what is your motivation to do such a thing? |
Ummm, isn't it already a mid engine car cuz the front of the motor sits behind the front axle?
How would moving the 50/50 weight distribution the car currently has improve handling? |
hey j9fd3s.the porsche transmission has the differential on the bottom of it and in the front by the bellhousing.you can stick the tailshaft end down the transmission tunnel and have a 12a based 3 rotor sitting where the gas tank used to be.
what is my motivation for doing this?well cuz i want to for one.it would be cool.it would be something no one else has. as long as the car remains 50/50 what is the big deal. |
you wouldnt be able to achieve 50/50 with a rear engine. It is a cool idea for a show type car.
|
Hell yeah!!! Go for it. If these guys don't like it, you can just send the pics to me when you're done. Intercooler can go down under the rear of the car with air ducted to it, kind of like they do with some MR2's
|
Thats what im talking about IGY.woowoo.hahah.
seriously i think it would be great. im looking at porsche transmissions right now.mmm |
Or air/water intercooler
|
Actually 40/60 is regarded as the ideal weight distribution for high power cars. With this balance you can run wider tires in the rear to put the power down while still maintaining neutral handling. This thread brings to mind a couple ideas I have.
1. Run a C5 vette, or porsche transaxle in the rear with a 20b in the front. This would give you more room to fit the 20B and slide the weight of the tranny to the rear of the car. 2. Find a porsche 996 C4 with a blown motor and do a 20b swap into it. I know it's radical but remember the 996 has big brakes, a beautiful paint job, german leather, 4wd traction, 4 seats and a book value that still exceeds the cost of the 20b conversion, unlike the rx7. 3. put a 20b or 4 rotor into a C5 convertible. Less exotic but more cost effective. Also I think you would have more room to work with than in any of the above options. |
i like the sound of a rotary porche
|
Redrum, while you're at it, why spend all that effor taking the engine out of the front. You could just put one in back and have two!
If it sounds like I'm just being a dickhead, I'm not...I just saw...I think it was Super2NR TV and they were testing out an Audi TT with a pair of 420 hp motors, one in front and one in back. It was streetlegal...at least somewhere...maybe they were in Germany? And it was completely badass. I don't know if it could handle, but it could sure as hell go fast. jds |
Porsche Rotary would be cooler!
How strong are Porsche transaxles? (the 915 is pretty weak) |
3. put a 20b or 4 rotor into a C5 convertible. Less exotic but more cost effective Yeah, so why not put a C5 motor in the FD while you're at it! I know someone produces a custom crossmember to do this... https://www.nopistons.com/forums/pub...#>/biggrin.png Am I gunna be banned for suggesting that? Check it out! Corvette FD https://www.nopistons.com/forums/pub...1047683329.gif |

Well im decided im doing a rear engine conversion.
i have also found a website that has a adapter plate, 4.5 lb flywheel, heavy duty clutch, pressure plate,my bearings,and a lightweight 8.5lb starter kit to adapt to any engine you want.i also found a guy selling 993 turbo transmissions with differential for 1400 dollars. |
the dilemma i found with that type of transplant is that the the 13b has heating problem in a front set up with the air cool from the front well in the back there is less airflow unless of couuse you do like a custom mr2 snorkel.
|
Japanese RX-7 mag had a mid engine sorta FD in it sometime last year. I think RE Amemiya made it.
|
it will def. be a cool project. it would be cool to do some rear scoops ferrari 360 style.
|
dont worry i most definitely plan on doing air scoops in the pettit flares to go into the engine bay.this weekend i will start working on the front like getting everything positioned correctly wiring,strut brace,cleaning painting,brake lines,brake balancer, and redo the radiator.ill map everything out on paper for the front and start going at it.
|
Well here are a few questions for you.
What are you going to do in regard to the firewall? What are you going to do with the rear glass since it's going to fog up like crazy with all the heat in the engine bay? How wiil you build (and out of what) the lining that's going under the hood to act as a trunk or housing for all the **** that doesn't have room in the back anymore? What about the intercooler? How's it going to get air, are you going to run a FMIC and run the piping all the way to the back? I hope you wont, it ads weight and isn't really a logical solution. That's it for now, this is what it might have looked like if the FD was MidEngined (Engine Behind Driver) from the factory. |
Well, as long as you can figure out all the wieght and ducting/cooling kinks, then is sounds like an interesting idea..
|
you can mount the intercooler(s) on the bottom rear of the car with ducting, like porche race cars. Im trying to find the Pic i want but cant seem to locate it.
i guess it depends on how you mount the engine, and where your ducts are. |
If you did that wouldn't you have a huge problem with rocks and other road debris hitting your intercooler?
|
yes, but you could rig a screen up to protect it. I dont think there will be enough space for that anyways
|
I guess that would protect you at least from the bigger rocks and serious damage.
|
someone who has money and time do this https://www.nopistons.com/forums/pub...IR#>/smile.png we need more creativity and courage in the world of enthusiasts, particularly here in north america.. at least in japan and australia there are a few crazy assholes who are willing to take risks. those of you who want to discourage him.. don't. this is what he wants, and he's asking for help and ideas.
|
yeah its going to be a great project.
|
its just going to take forever.hehe.
as far as rocks hitting the intercooler/what stops sticks and debris from hitting a front mount?nothing.it should actually more protection being in the back |

What are you going to do in regard to the firewall? A thin sheetmetal construction will put up as a skeleton.On the inside compartment it will have insulation tacked on then and interior theme to match the rest of the inside.On the engine bay side, I will have heat foil insulation. Something simular to what they use for the metal looking sunscreens for car windshields. What are you going to do with the rear glass since it's going to fog up like crazy with all the heat in the engine bay? Heat resistant lexan glass.The same type of glass they use in all your rear engine vehicles with heat problems. How wiil you build (and out of what) the lining that's going under the hood to act as a trunk or housing for all the **** that doesn't have room in the back anymore? Well since it will not be driven in the rain, it doesnt have to be 100% weather proof. But again an interior exo skeleton will be made over the gas tank once placed. A carpet lining will be placed in the old engine bay, and weather stripping will go completely around the hood area. What about the intercooler? How's it going to get air, are you going to run a FMIC and run the piping all the way to the back? I hope you wont, it ads weight and isn't really a logical solution. Intercooler will have an electric fan for good measure and be placed diagnally near the bottom. That's it for now, this is what it might have looked like if the FD was MidEngined (Engine Behind Driver) from the factory. Um mid-engine means engine behind front axle in front of rear axle. The fd is mid-engine. It is mid engine front. There will be carbon fiber pieces to cover the new engine bay and heat wrap to keep heat down as much as possible. |

You coudl do custom fiber glass ducts for air off the roof. Kinda like the eclipse from F&F but i'd make 2 big ones on each side. You could use a VMIC and run a duct just to it. You could use sheet metal in the front. You dont really need to thou you could bolt the rad and computers all up to the bay pretty easy. The rad piping might be a bit of bitch but it shoudl help in cooling. You coudl put weight in the front too to balance it out.
How would you shift thou the gear box would be in the back. Or is it a auto? Personaly you shoudl take all that time / money and just go get a 20B and make a sick beast. |

I know what kind of Mid-Engine layouts there are, therefore I said Mid-Engine (Engine BEHIND Driver). Otherwise, it looks like you have everything planned out nicely, good luck with everything, please keep us posted since this would be a definite breakthrough in FD modding. |
