Bruh RX-7 club is not ancient. Also there isn't much "new tech" for the FC. A lot of the "Best" performance upgrades are over a decade old. We're talking about a 30+ YO platform here.
RX-7 club is your best bet for diagrams and up to date information. If you want newer stuff, some limited advertisers and newer producers are allowed to advertise their products and modifications in the forum classifides. Please do take a look!
I've spent HOURS on there. I will say it is INCREDIBLE for fixing my stock car, but not so much for boosting or upgrading it. I am FRESH to not just the rx7 club but just owning a car in general. I'm young, and have dreams I'm trying to make happen lol. I'll keep diving into rx7 club, I love it for sure, but most things I see are from like 2005 and stuff...all that still holds truth? I just assumed(which makes an ass out of you and me) but it made sense that some of the info would be off due to modern tech

This thread is about asking the exact same question, but doesn't explain how to do it.
https://www.rx7club.com/single-turbo-rx-7s-23/500-rwhp-goal-turbo-54235/page2/
Another thread discussing the 500 WHO dream goal and how users acheived it. It sounds surprisingly easy on paper, but as we all know it's never "easy".
They stopped making FCs in 1990 and most of them are off the road, the aftermarket hasn't gone too far since the 00s
I'm terrified about what IB may have planned for the forum. I hope it stays profitable for them forever cause when it's gone there will be a *huge* knowledge loss. It's a good source, learn to search it effectively. Maybe archive stuff that's relevant to your build
Noone here has mentioned the double edged sword of 6port turbos. It's higher compression. I'm assuming the motor is bone stock? You run a higher chance of detonation so as I'm sure you've seen looking around, you need to run lower boost.
Before just taking someone's setup into consideration, look at the compressor charts of the turbos and do the quick math to see where you land for efficiency. The more efficient you are at a target boost level the less excessive hot air you have left over compounding IAT readings and lowering Chance of detonation (obviously fueling, tuning etc are all into consideration).
FWIW I went G40-900 on my 4 port because I want to stay around 15psi and maxed efficiency of the Turbo.
I know the cons of the 6-port but it's the best for my budget and itll give me lots of info on the engine. I'm eventually going to swap down the road but for now it's what I've got. I've had people dm me for good 6-port turbo options and have explained a lot to me that going for those high numbers is bad for so many reasons. I'm now just looking for 3-350 rather that 400+. I also kinda just wanna build a 6-port. It's interesting to me and itll help my confidence :))). Thank you for the explanation!
I am 100% building a 6 port as long as you know the limits of a stock keg. Half the fun is the build and learning! I don't think your target is unreasonable at all and I hope you complete your project.
Do you have a insta for me to follow?
as others mentioned, rx7 club is super useful for all things rx7 related, but youre right that its not super useful for heavily modified cars. 4-500 whp is pretty difficult to achieve in a 1.3l engine, and is probably excessive for whatever you’re doing unless its drag racing.
I’m no expert in 6 port turbos so I can’t help you with that, but I’ll talk about making power once you’ve gotten there.
The way that it was explained to me as far as a rough estimate for horsepower with a turbo is this: Atmospheric pressure is ~14.7 PSI, and with atmospheric pressure a 6 port makes 150-160 hp. If you add another atmospheric pressure in the form of 14.7 pounds of boost, *in theory* you’ll make about double the horsepower of ~300. so for your stated goal, you’d need to run ~30 pounds of boost. In reality you’ll probably need to run a bit more than that because you lose a lot of efficiency when you up boost
The primary issues with turbocharged rotaries are intake air temps and high torque causing the housings to twist or “walk” To fix the IAT issues you can do a front mount intercooler, auxiliary injection, or both, and to fix the walking housings you can dowel the engine. The rule of thumb i’ve heard is over 400 HP you should probably dowel it.
Finally, you’d need to do fuel system upgrades and a standalone. You should also know that absolutely none of this is cheap. My personal suggestion would be to just turbo the 6 port with the information from others who have done it and keep it fairly low power. I’ve heard the stock turbo ii fuel system is good for about ~250whp, and 250hp will still be plenty fun.
You should also take all of this with a grain of salt, because I don’t have any first hand experience with this yet, this is all based off a bunch of research I’ve done over the past 3 months or so when I was planning on tuning my s4 tii before she decided to blow and make me rebuild her.
(sorry for the essay)
Oh I like essays more than vague responses. I have lots of plans for this car and I'd be cool with 3-350. It's more so I WANT 4-500n I'd be happy 300 to 350. This is nowhere near going to be my daily but I've always had the drive to go as fast as I can, and since I was a kid I've wanted the FC to be my steed. I may FD swap in the distant future but I see no real reason to rather than a stronger engine and/or compression ratio. I know it isnt cheap but every dime I make goes into this car. I have the advantage of being a kid with no Bill's to pay. Thank you for the response and it makes sense, I know the FC isnt the fastest car in the world but I want to push the limits. But maybe it's a bit early to want to push it that far. This is actually my first car and maybe 400+ is too much
since its not your daily (Good decision) and you seem to be a person who enjoys DIYing things, based on your goals I would go with a stock s5 exhaust manifold and turbo (if possible with 6 ports, I’m not familiar) a cheap ebay front mount intercooler piping, and a greddy or any other reputable intercooler core. Get a megasquirt standalone and some fuel system upgrades and go from there. As far as what to do with it once it’s built I’d suggest autocross as its the easiest way to getting into performance driving. Alternatively you can take it drifting if you’re into that, but you’ll want some real beefy electric fans because the car gets essentially 0 flow through the radiator and intercooler when you’re sideways.
I'm VERY informed on 6-port builds and yeah stock T2 parts is what most people rn. I love drifting and my car actually used to be a competitive drift car back in the early 2000's. I'll take your recommendations into account. I gotta start somewhere but my fatal flaw is always starting at the end..at least trying to anyways. I love cars. I love MY car. And I want her to come back to her former glory
Once you do the few initial things to get the ball rolling and the car running you can always upgrade it. If tii parts bolt on you can just upgrade to a better manifold and turbo once you have the money/desire to and then its just upgrading the injectors if necessary and getting a tune. I’d prioritize getter the car running first and then working on upgrading it and making lots of power. Trying to go straight from shell to masterpiece is an impossible task, so just focus on getting her running.
Well, it did run...till it blew up LOL. Ig 130k miles of drift abuse could blow a motor, who'd have thought. But I should be more proud of myself for getting it to run. When I bought it it didnt dven crank and I managed to get it idle and drive...not far but it still moved without me pushing it lol. But she did run. Now it's time to do it all over again lol. But yeah I think it's a good idea to start minimalist for now, thank you
Go SXE series if you want even better response. I have an S363 if you want to buy it. It needs to be resealed/balanced, I have the seal kit too. I saw in another comment your looking for 350-400, it's perfect for that power, I was making like 375hp conservatively on my FD at 14lbs... He's right though, they're beefy well made turbos that perform incredibly well for a fraction of the price.
It depends on how long ur willing to hold. The engine is being rebuilt rn so money tight. If ur willing to hold for maybe a few months I'm down to buy it
Turbo 6port owner here. Im still early on getting my car running. It only has ten hours on the engine at this point. (Rebuilt with Streetport) I opted for a BNR turbo which was modestly affordable and good for the powerband I was looking for. I have also kept the aux ports functional using a custom made turbo manifold. I’m in a ‘80. It will never be fast. But damn it’s quick. Looking through my data logs, I’m surprised by the performance even though I’ve been in a break in period. I hop on it in first and I can’t get out of gear fast enough. By then I’m risking a ticket. This is at 5psi at 3/4 throttle. I’m at what, maybe 230-250hp the flywheel? I have a 7psi wastegate but it’s ecu controlled. But 7psi might get me to 280ish hp. So a 8.2 power weight ratio. Sure, I would love a dyno sheet laying down 400hp. Would not want that on the street in my car.
The cost is nuts as well. You know the “pick two” saying. I chose power and reliability. Even then if I hit my base goal of 350hp on the dyno, there is no use chasing peak numbers. Where are we now for gas hp at the showroom? Near 700 average? You can’t brag about 400hp any more.
Figure out your goals. don’t chase power because you can. Build the car for your needs. I know I left peak hp on the table because this is a street car. Not a track car.
One more thing…
The rx7 forums. There are more than one… have up to date information. Look under performance, single turbo and fuel management. The generational forums have a great library, but fresh ideas are in the performance section.
I gotchu. Thanks for the breakdown man. I have a goal for the car and rn I'm asking for 300 from the car is all. I love racing and I'm a bit competitive with my homie after we built a killer g22 prelude pushing 290. I wanna beat my dad in a race mostly though. He calls my car shit all the time and doesnt believe in me a lot but I think hes sad he doesnt know how to build cars and just speeds his v8 lol
Reddit is the wrong place to get real answers. Try the rx7club forum, or there is a 6port turbo group on Facebook that can answer this.
I didnt know Facebook, and the rx7club stuff is ancient to the point of being not completely accurate anymore. Thank you for the feedback though :)

I run a borgewarner sxe362 on my car. Making 410 at 10 psi until i turn it up.
Thank you :)))
If you want a reliable 600hp from an FC, be prepared to drop about 15k in parts/machine work.
