Well I have been holding off on getting a thread going on here until I got farther along in all the cluster eff that is going to be my car. But the cold winter is keeping me from the garage and just sitting in front of the computer, so I figured I would share things that I have done.
I seem to be taking the road not so most traveled with my car, you know reinventing the wheel per say. But it gives me something to do on the weekends while i finish school. I keep saying i keep my sanity in the garage, i just go visit it on the weekends.
So lets get started...
first things first, even though i just sold my rally rx7, i did that more for the sake of school and wanting someone to enjoy the car rather then it just sitting in the driveway doing nothing. this car will also be a rally car. i got a smoking deal from a friend of an already caged rx7. but it was a roller and nothing more. so it came home, spent a little time with the porta power getting the nose strait and then i got to work.
Next thing to get into order was boxing of the front part of the frame. With now 2 rx7 rally cars, and talking to the old timers that used to rally these back in the day. the noses of the rx7s are pretty weak. it's because just past the steering box mazda reduced the amount of metal that they used on the frame, making it pretty thin. so what you see with a lot of hard use off road is the front part of the frame will start to buckle right around where the cross member bolt on. on this car the frame was so bad it was torn. i wish i would have taken a picture of it, but it wasn't pretty to say the least. So I boxed the inner, outer and under and tied them all together to make it as strong as i could.
Next on the list, as with many of the other first gen guys out there, was to swap a 2nd gen sub frame in. clearly, i'm not covering any new ground here. but it ties into my next "why not" invention.
Struts, yeah what to do with struts. Stick with stock FC stuff, buy some fancy super bitchin suspenders, or make something from stuff i had laying around. with some FC struts i got with the front sub frame i started to measure up with some other struts i had laying around, and with some grinding, some cutting, and very carefully removing the ears from the FC struts, i put them onto a set of 05 Subaru STI struts.
STI STRUTS?!?!?!?!?! yeah STI struts. my thoughts behind them, 1. i just happened to have them laying around my garage, 2. they shared the same tube diameter as the FC stuff so it was just a matter of getting the ears off with out destroying them and 3. my personal favorite, they are tough, they are an inverted strut from the factory. I actually ran a set of STI full suspension on a legacy rally car i had for a full event. other then sitting a little to low, they held up just fine. And the fact the legacy was a 1000+lbs heaver, i'm not to worried about them living a very easy life in the front of the rx7. I also wanted to stick with the Subaru top hats because they have been known in the rally world to be pretty damn strong. Many other car manufactures actually swap to subaru top hats because they are super cheap and strong.
