Dreaming 92FD is about to teach me.
Just bought an imported FD with 38KM on it. Mostly stock, so far it looks like the only mods are some weird boost controller (maybe? will post pics soon) an HKS exhaust, body kit, 99spec lights/bumper, and cusco coilovers.
First thing I noticed was a hesitation when getting on it so I got a PFC installed and it immediately cleared up any issues in that department.
I've also got a missing front sway bar, someone trying to drag? Not me.
My ultimate goal is 300-350rwhp. Trying to keep it alive for a good amount of time while still having a bit of fun.
I'm totally open to suggestions and recommendations.
Current plans:
In order though; Brakes, Suspension, Tune.
I want to be able to enjoy the car a bit while I work on it. I don't plan on going the cheap route at all though and will try my best to buy the highest quality of everything. No ebay special turbos or anything like that.
Any tips?

Current plans:
- Brake upgrade: Power Stop K4186
- Boost controller: Greddy Profec B or *Apex-i? (*would have to order from Japan)
- Suspension: Sikky adjustable front sway bar (You know, since I don't have one at all.)
- Cooling: RE-Amemiya AST, upgraded inter-cooler*, silicone vacuum hoses, radiator*, secondary oil cooler*. (*I honestly can't decide between fmic, smic, vmic, or brands for that matter.)
- Fuel: Denso 1020 Fuel Pump

Welcome to the Wonderful World of JDM
Great to hear you have joined the growing RHD FD owning contingent in the US. We have very many up in the Vancouver, B.C., area as we have a ten year headstart on importing. Follow us on the Westcoast/Western Canada thread under the Canadian Forum. Plan to join us for Sevens' Day on July 7th in Abbotsford, B.C.

First off, we need some pics! I can probably help identify the boost controller/whatever.
Banzai Racing has an excellent thread showing step by step how much horsepower different mods make. I highly recommend reading it, doing mods smart can go a long way for a happy car.
But, before any mods make SURE the maintenance is up to snuff. A lot of cars that are imported have sat for who knows how long, all the fluids are super old and broken down, rubber is deteriorating, tires are shot, etc. Take time and go through everything.

^Yep. If you are at the point where you are outrunning the stock brakes, you're either doing something wrong or you are doing SERIOUS track work and are ready for the next step.

I would just like to add this: For the factory sequential setup, the Power FC does a fine job of controlling the boost. No boost controller needed.
Typically 12psi is near the safe limit for stock turbos, anything more is just making the air hotter and over works the turbos. Around 14 PSI, you will not have enough fuel.
So, I'd settle for 12 psi, get all the maintenance up to date, a high flow cat, silicone vacuum hoses with Dale's check valves, and a SMIC. There are tons of SMIC out there that fit and cool well, a v-mount can be more effective, but usually require a lot more work to install.

Pictures at the bottom!
So sorry for the delay! Been working on the car and just getting myself situated before the big move.
The boost controller "thing" was actually a Cusco suspension dampener. Honestly, didn't even know that was a thing but it's extremely interesting.
There is an HKS turbo timer beneath the steering wheel but I haven't gotten it to turn on yet. I'll have to give it a look over.
No mods are really getting done until everything is solid. Here's what I've done so far;
Oil change, power steering fluid, transmission fluid, radiator fluid, and brake fluid. <<< Flushed and seafoamed as well.
Changed a wheel hub assembly that had a bit too much play.
Ordered brand new tires because the old ones were like rocks.
The new brakes go on Monday I got them for a very good price and I considering them future proofing.
Issues that I've noticed; It's got the 99 style bumpers but the fitment is a little... off. I'll take better pictures but I don't think it was done right so I'll probably order a new one and do it correctly as the front bumper has little cracks along it. The front right fender has a crack on the interior where the bumper is currently bolted on. (Was zip tied...)
The side skirts fit perfectly but the rear bumper doesn't line up as flush as it should.
The center brake light has a small crack so that will need replacing as well.
Mostly cosmetic issues which will be addressed after I make sure the engine and everything else under the hood is running well.
Ooo! My first "RX7" problem. So I get the car and take it for a drive. It starts idle surging. I google the hell out of it and I really can't figure it out. I'm running around, testing it with lights, ac, wipers. lol. I try it all. I give up for the night and last Friday I decide to go to a meetup with some friends. We all have our cars out and are just having a good time when out of nowhere my car just dies. (Out of nowhere being me going a little too hard with my first twin turbo rotary.) I pull over and restart the car, it's sputtering and doesn't want to start. Pop the hood and what do you know, the boost sensor line popped off. My buddy being the 24/7 mechanic pops his trunk, we replace it with some silicone hose he has (exact match on the inner diameter) and clamp it on with some steel snaps he has. Car is back to it's little idle surge. That's when I finally decided to mess with the valve on the throttle body. We play with that a bit and it changes the idle but it continues to surge randomly. I google a bit more and find a thread referencing the settings in the PFC commander. So I whip that bad boy out, play with the idle settings a bit and what do you know, no more idle surge at all. Idles perfectly at 950 when warmed up and a little over 1100 when I have the AC running.
Like I mentioned above, it was just a good price and some future proofing as well. No crazy driving at the moment.
Just so I understand; the Power FC can limit (or monitor) boost? Is there a setting in there? I didn't happen to see it. I read a couple of threads mentioning boost creep and there is currently a full HKS exhaust on there but I have no idea how to tell if there is a high flow cat or not. (Is the visually different than others? I could take a picture.)
I DID order a full silicone hose kit and that will be taken care of very soon. As far as SMIC go I've been reading up on a lot but it seems like there are always people who have to modify in some way to get the intercooler to fit; even if it is supposed to slap right in.

I REALLY need a new shift ****. The leather cover on mine slips around when trying to shift. Ugh.

Yes, the Power FC controls the factory twin turbo setup with the factory solenoids to operate in sequential mode. It does have over boost fuel cut if boost is 0.25kg/cm2 over target.
You can see the target boost and duty cycle in one of the screens, it looks like this:
Pr. 0.70kg/cm2 54%
Sec. 0.90kg/cm2 67%
These are arbitrary numbers and not the actual or recommended settings.
If your solenoids and hoses and check valves are in good shape, the Power FC does a fine job of controlling boost. What I meant about your exhaust is this; without a catalytic converter, the is so little back pressure that wastegate is the restriction and exhaust goes thru the turbos more easily resulting in boost creep. Having a catalytic converter maintains a bit of back pressure and reduces the likely good of boost creep. Option 2 would be to take the turbos apart and port the wastegate.
Sounds like you are on a good path so far, now you need to post up some pictures so we can all see your ride.
*Ninja edit* Just saw your imgur link. Nice car. Only recommendation I have is ditch those tail lights for factory ones. It would look much nicer with the dark paint.

Yeah, I don't like them much. But I'm not doing anything cosmetic (aside from refreshing the shift ****) until the mechanical things are up to snuff. The car is a blast to drive as is and still turns heads.
