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.

Because they are built with the mid engine in mind throughout the design!



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
