Looking to Build or Buy your dream rotary powered car?

Our tagline has been to collect, restore, and modify JDM legends, but starting in 2026 we’re dedicating most of our time and effort to servicing the rotary car community, specifically the FD RX7 (while keeping a few of my other non-rotary favorites). We’ll be working on a few cars for folks this year, but more importantly we’re trying to get the word out on what you could learn if you had hundreds of conversations with rotary experts that have been successfully servicing or driving these cars for a very long time.

How I think I can help the rotary community enjoy their ride:

I’ve been fortunate to own FD RX7s off and on over 30 years with all kinds of build level (lots of stock and OEM+ cars, maxed out twin turbo cars that made safe reliable power, and now I’m getting into some pretty serious single turbo builds using the latest parts and building 2 rotor cars with 400, 435, 500, and even 550 WHP builds like my Dom and Han RX7s.

Over the years I’ve had countless conversations one on one with rotary shop master technicians and owners, and it’s simply not possible for every rotary owner to gain this kind of access. Again I’ve been fortunate. Rather than hoard that information, I want to share it via simple blogs on this website and in a set of new YouTube videos in a way that’s informative and easy to understand. Mark S and I already did a local users group and engine build seminar at the FX JDM shop summer 2025 where we gave out tons of this type of information to a local group of owners and I think some of them found some of it pretty helpful. That first user group meeting (we used to give those at the company I worked at) was kind of where the idea came from to start the blogs and YouTube videos.

Here are a few of the topics we’re going to share our views on (and I’ll move this content to separate pages as this is a bit much for a home page).

• Why the rotary engine has such a bad reputation and what can we do to prevent becoming another horror story?

• I want to buy a car, what do I need to look out for? Even I’ve bought cars wrong and I have 30 years of experience buying at least 20 FD RX7s. We’ll cover what to look out for to avoid being that guy that needs a rebuild on day 1 of ownership.

• I want to import a car, how do I do that or are there any trusted FD JDM importers (YES! I bought the donor 1997 RHD black FD from a great shop in Florida and then I turned it into my Han RX7, and I’ll share his contact information with you and will try to get his permission to be a link on our website.)

• I just bought a rotary powered car (or maybe you’ve had it for a bit), what do I need to know to not be that guy that had to rebuild it 3x and still might blow an engine on my next high RPM / high boost pull?

• What do some of the folks that learned the hard way wish they’d been told before it was too late?

And then there’s power mods (this is where the real fun is at). We’ll be sharing success stories that we’ve had or our friends have had with these types of power builds:

• Maybe you want to go OEM+ with free flowing exhaust and some safety mods,

• Maybe you want maximum safe power that your stock twins are able to handle before spinning themselves into twisted metal from over-boosting like many others have done? They’ll die really quickly if you run too much boost PSI through them.

• What to do for a stock twins replacement now that Mazda has stopped making them and it’s nearly impossible to find a good set?

• Looking for a safe single turbo twins replacement and don’t want to overstress your motor / try to keep it safe? Add some horsepower but not so much that engine safety becomes a larger concern?

• Want to hit 400 WHP at safe boost levels for Pump gas 93 octane? Learn how a semi-P build that makes the same power at lower boost levels is just the trick for rotary engine safety.

• Maybe you want to go nuts like my Han RX7 and take the engine as far as the stock drive train can handle (around 550 WHP before 3rd gear strips on pulls)..

• Maybe you want to make Rob Dahm level power - 700 WHP 2 rotor at high boost levels going beyond 93 Octane pump gas

• Maybe you want to make a 4 rotor like Rob Dahm - What does this take and where do you start to get the parts?

Here are some of my FDs with a brief build summary. We’ll be posting more information on these fairly common types of builds soon and later in the year we’ll try to make some YouTube videos where we compare the cars and do some real world driving with them and race them against each other and against some of my other cars.

My mint condition 12k mile never taken apart 250 WHP (stock was 220WHP) She’s OEM + exhaust (downpipe, hi flow cat, catback K&N air filter, and Power FC to ensure proper cooling fan control over stock ECU)

My Montego Blue 99 body kit twin turbo boosted to reliable 315 WHP - Power FC, open exhaust, SMIC, Koyo N flow radiator, 3 bar GM map sensor, etc. Previous owner cooked the coolant seals so I rebuilt it summer 2025 in 6 weeks.

My Dom Rx7 435 hi boost setting or 400 WHP low boost setting ported, balanced, and built by Rotary Performance - HKS GTIII-4r special setup plug and play single turbo - 435 WHP, 400 WHP on safe street boost.

My Han RX7 - 550 WHP EFR8374 semi-P built by Rotary Performance with balanced rotating assembly to help me in my two step battles.
