• BUILD: Corvette-swapped Mazda RX7 Project

      Well, after about a year, I got bored of the car, changed a few things up. (most of the work was done in the dark after work, so I don't have many pictures of the work :/ sorry.)

      I changed a few things up with the motor, along with the body.

      Motor wise, with the help of friends, we did a heads/cam swap.

      New motor specs:

      Heads: TSP Stage 2.5 Heads
      Cam: TSP MS3
      Intake manifold: BBK SSI Ported and polished. The mouth was ported to 92mm to accommodate for the throttle body, and the runners were ported to match the ports of the heads
      Throttle Body: PTM 92mm

      I had to get a custom adapter made as well for the throttle body to work. The throttle body was 4 bolt, and the intake was 3. so i took it to a local machine shop, and had a .5" spacer/adapter made.



      And a pic with the throttle body on.

      Well, long story short, The car is finally ready to be tuned, we start tuning it, and fry the 98 pcm, which if you dont have any experience with gm engine control, suck in short.

      Instead of buying another 98 pcm, I searched a ls1 forum for a nice 99-02 pcm and decided to re-pin my harness once I find one. After about a month of searching, I found a really nice 2002 pcm, and buy it. So the fun began. (again, no pics, sorry guys) So I started to re-pin my harness, which is about 200 wires. It took me about a month to do, working on it off and on. Now I'm just waiting to buy a couple more things, and put in my rod bolts, twin scroll timing chain, and ported and shimmed ls2 oil pump. Then it will be time to tune, and have back on the road again! I'm hoping to have it out at KMS in march, I wont have everything done to it I'm working on, but at least the motor will be where I want it.

      I'm also working on doing some things with the body and suspension, continued on next page.
