Hey guys, New to this forum but old to RX7Club.com and thought I'd start up on here for suggestions, comments and help of all sorts. The build thread I'm posting on 7 Club can be found here: Austin's FB TII Swap - Details and Pics Aplenty! Here is the general idea for the build: Take an unmolested 86,002mi 1984 Mazda RX-7 GS with the original 12a engine and transmission and swap in an S4 1987 RX-7 low-compression 13b Turbo II engine. Essentially doubling the hp and torque, getting similar gas mileage, and having much more fun with the car and its power-to-weight ratio. I will be doing the build in stages I've decided (with the help of the lady and a friend on 7 Club) and the stages are; 1. Get it running under its own turbo powered rotary awesomeness Remove 12a and trans Mod gas tank for FI pump and sending unit Install 13bt engine and transmission Custom trans mount and driveshaft Full ECU and wiring harness swap Leave almost everything else alone Just get the car running reliably all summer of 2013 2. Fix anything that I don't like and upgrade anything necessary - so a hypothetical list Remove 13bt engine for some re-mod's Paint engine bay FC front subframe swap for R&P steering and big brakes and 5x114.3 wheel pattern FC rear brake swap with custom brackets LSD rear end completely built up Aftermarket ECU of some sort Dyno tune from a professional Re-do exhaust for more flow Here are some pics: 1984 Mazda RX-7 GS 1.1L 12a carburetor engine Stock engine, trans, rear end No ECU Complete burgundy interior 1987 Mazda RX-7 Turbo II 1.3L 13b turbo engine TII transmission Stock ECU Interior partly gutted but should be complete [video=youtube_share;UauyfDwduIY]http://youtu.be/UauyfDwduIY[/video] [video=youtube_share;JRdpu31YSlY]http://youtu.be/JRdpu31YSlY[/video] [video=youtube_share;oqGUqjgeWV4]http://youtu.be/oqGUqjgeWV4[/video] A few pics of the engine being taken out and prepped for install into the FB: I look forward to meeting up with some of you guys this coming summer - if it ever comes - and appreciate any input!
