Well ladies and getlemen, I am a proud owner of a brand new(atleast to me) 1990 N\A RX-7. The first order of business is doing a turbo swap. I have decided to go 13B-RE with it. I am very proficient at wiring, since I have done it before on other cars, but the problem with the RX-7's are the connectors. I've asked here once before about them to no avail. I was wondering if ayone has ever done this, maybe matched up some generic connectors or information on it or something similar, so I have a place to start.



While your already reading, I might as well sneak one in... will the fd 5 speed trans physically fit in my 2nd gen? Ive read that the clutch release system is diffrent, so I would use a slave cylinder from an fd, right? Also if running a T2 diff, what driveshaft would with the fd trans?

If your proficient it should be no problem. Wiring is all about taking ur time and attention to detail. As far as the tranny there are people with fe (Rx8) 6 speeds trannys in their fc's in their cars. so im sure that an fd tranny wouldnt be a huge streach... (insert people that know here)

an fd tranmssion should physically fit however there two issues:

fc clutch is a push type clutch

fd clutch is a pull type clutch



and



fc has a transmission mount in the cneter of tranny

fd does NOT have a tranny mount like fc it utilitzes a PPF (power plant frame) which connect the rear portion of the tranny to the rear diff.



First of all.

a Turbo II Tranny can support almost as much hp as a FD tranny (this is unless you plan on 500+WHP)

Second of all, you would have to utilitze ALL clutch components from an FD and every FD clutch cost more $ than the comparable (Hp/.tq rating) clutch for an FC



so basically to fit an fd tranny in an fc you would have to spend a lot more time money and fab a custome mount for very little advantage over a TII tranny



JUST INSTALL A TII Tranny and be happy your not paying for expensive fd parts

So I guess T2 it is, but how about the connectors? Does anybody have any info of something else I could use, for ex. GM weatherpack connectors or other generic connectors?

The 2 wire ones like the injectors are available. Check with an aftermarket fuel injection company. other than thous i dont know. You may be able to find them somewhere.

yeah some you can get, like the injectors, some you can get but have to buy 100,000 at a time like the ecu connectors. and then some you just cant get like the fd CAS connectors

I also have a 1990 GXL that will be getting a TII conversion and I too will be making a complete wiring harness using some of my old connectors and some GM Weatherpack connectors ( for air temp and coolant temp mostly). I will be using a Megasquirt standalone without an airflow meter so I won't have to use that connector. Bosch injector pigtails and most GM Weatherpack connectors are readily available. (Pep Boys has them).
