well. let me explain first im been in the rx7's for 10+years now i had both 1st and 2nd gen but now i have a little project in my hands that im planning to put a FD engine on a FC body. im asking here because im planning to keep the sequential turbos on the motor and i been reading alot about 3rd gen cars and i see that you cant eliminate the rat nest, but my question is i cant get rid of it at all or i can parcially eliminate the rat nest? like what solenoids i can get rid of? im not have to worry about passing inspection because my car is over 10 years and i dont have to worry about it too much about emissions ****. and i have usdm motor so the EGR can go right? plus im installing a power FC because seems to work better with the 3rd gen sensors. i need some imputs. im been searching alot but not all my questions have been answer yet

thanks

Basically you're looking for information on turbo system simplification.

Rob Robinette's site had a pretty decent write up:
http://www.rx7.org/Robinette/turbo_s...lification.htm


There's also tons of info on this forum if you search for simplification. The basic gist is that there are 4 main solenoids controlling the turbo transition, 2 more control the boost (wastegate and precontrol). The rest are emissions or "extra" systems and can be removed if desired.

hmm i must of miss this, because this didnt show up when i searched. bu this is more simple that what i thought. thanks man

 

I have a 1985 GSL-SE with a stock 1994 fd motor and auto trans sitting in place .I plan to do the simplification on it .I still have the plate with the resistors mounted to it that I used on my 94 before I got the PFC . The SE will match my FD ,both silver with red interior .

 

I did the sequential simplification and now have a box of parts that weighs probably 15 pounds not including the air pump. Amazing how much stuff under there can go away!
