Best setup
hello everyone. I hope your New Years was great. I wanted to to get some input on parts and upgrades. I have a 93JDM FD. I want to upgrade as much as I can to get as much power as I can. HOWEVER, I want to keep the engine bay stock look. Any and all help to include links, pics and even personal setups is and will be appreciated. |
Keeping the engine bay looking stock will severely limit your power levels. The stock intake/intercooler are far too restrictive and take up too much real estate that will affect ability of other modifications fitting. If it were me and I wanted a stockish setup, I would do the following:
Power FC with a professional tune Autoexe intake and intercooler Downpipe Racing Beat dual tip catback Koyo radiator. You will be able to safely make 300-320 hp. Past this you will need fuel system and ignition upgrades. The stock turbos quickly lose reliability past 350hp. At that point I would go with BNR stage 3s. |
So far mishimoto radiator, 99 spec turbos, pulleys, and thermostat changed. Nothing more or less :| i want the bnr turbos, but then I’d want to get everything I can out of them. |
Why mishimoto radiator?
IRP has a ton of experience on these cars and provided some solid advice. Not sure how much pics of a stock engine bay will help but banzai has this solid thread https://www.rx7club.com/3rd-generati...added-1104322/ you could do everything they do except for the intake. |

The goals are this.
Lowest intake air temps possible. for power and safety. Rock solid coolant temps, and oil temps. typically you want ducted radiator and ducted dual oil coolers. Then work to getting a better more robust fuel set up. get a denso supra pump which drops in. I would also upgrade all the fuel injectors to Bosch EV14, 550 or 650CC primaries and 2000 secondaries. this does need new fuel rails for both primary and secondary. this will have the car running GREAT with much better injectors. After this is all up to you. cold air into the intake is more important than a humongous intercooler. Run a really large intake filter as well, lower pressure drop across the filter which means the turbo works less and the air is filtered better. The name of the game with the stock twins is getting the pressure drop across components as low as you can to keep the turbo's in their efficiency range when going for power. |
