We can help you get your FD back on the road

The well known rotary shops are so busy they probably aren’t the best place to help you with your basket case barn find. That’s where we can help you. We have amassed a collection of known good / hot tested short block kegs and complete take out motors (a motor with every accessory on it)

We can customize it so you only pay for what you need.

We’ll resell the rest to someone else looking for that part.

For example, want us to remove every single emissions and twin turbo-only part like we did for our Dom and Han builds?

Want to buy a short block that’s been hot tested on our engine stand?

Want a to buy a known good 13B that doesn’t need a rebuild on day 1?

Want to see a video of it running on our engine stand? Watch us do the compression test? See it hot starting?

Try to find that anywhere else.

We’ll even add wires through the firewall grommet so you can additional sensors.

I have yet to need an expensive brand new wiring harness. And if you do, I can convert readily available JDM harnesses to USDM pinout to save you money!

Just contact us and let us know what you need

Let us know a little bit about the state of your car and what you need so we can schedule a consultation call.

Want to see it in action?

Our shop cars demonstrate just about every configuration a 2 rotor FD can be built for (all with safe boost and safe AFR levels)

  • Red Touring 12k mile stock+ (Power FC, downpipe, hi flow cat, catback, K&N air filter) making 250 WHP vs 220 stock

  • Montego blue 36k mile maxed out twins car with safe 315 WHP / although the 30 year old twins really shouldn’t be pushed this hard. Even my car’s twin turbo seals are starting to go, and these are 30k mile turbos off of a cream-puff automatic never driven hard. The time of the twins has passed.

  • Dom RX7 (See us at Fuel Fest Dallas 4/25/2026 Texas Motor Speedway)

    • Engine keg built by Rotary Performance, single turbo making up to 435 WHP on a plug-n-play HKS Special Setup turbo kit.

  • Han RX7 (See us at Fuel Fest Dallas 4/25/2026 Texas Motor Speedway) EFR8374 / 550 WHP semi-peripheral port (Semi-P)

    • Engine keg built by Rotary Performance, Semi-Peripheral Port!!!! (Semi-P),

    • Will make 525-550 WHP after we break it in. Semi-P makes about 100 more WHP at the same boost level as a street port engine.

      Blowing 18 PSI through a big hole makes a lot more power than the same 18 PSI through a smaller hole.

      Keg built and balanced by master technicians at Rotary Performance with Goopy seals that REQUIRE premix.

      Our take: Han is about as far anyone should an FD on the stock drivetrain

      • 1/4 mile racers in the late 90s blew a lot of 3rd gears, axles, driveshafts, and stock diffs beyond this power level - Real world data straight from the mouths of those that got really fast at rebuilding the 5 speed since they had to race on stock drivetrain.

What about the 4 rotor? What about 700 WHP 2 rotors on Social Media I see everywhere?

Click here for a link to Epic Motorsports Brendon 4 Rotor FD Build that they built

Rob Dahm builds awesome 4 rotor Pike’s Peak racing / 700 WHP 13B FC dyno proven motors / 12 rotors!

These aren’t the types of street cars that we build here.

For those types of builds check out his social media - He’s doing awesome stuff, but I don’t think he’s running what I consider safe boost levels on 93 octane pump gas and he’s definitely not limiting his builds that way. (We salute THE Rob Dahm).

E85: I haven’t had a chance to explore E85 other than my high HP MKIV cars. I’d like to but part of my problem is I don’t drive anything other than my truck daily, so by the time I get back to an FD the E85 has accumulated too much water. Unless you’re daily driving and cycling your gas tank every couple weeks, it’s advisable to maybe skip the E85 for now.

We can sell you just about anything you need to complete your motor build.

EVERY SINGLE part OUTSIDE of a complete FD RX7 take out motor 13B-REW (anything that bolts to the keg, known good parts)

EVERY SINGLE part INSIDE of a 13B-REW short block / keg (good usable low mileage irons taken from known running local motors or my cars (I always use new irons and rotor housings for my collection leaving known good exceptional parts available for the community.

Every keg major component (front, mid, rear irons, rotor housings, rotors, oil pan, front cove) plus parts bundles for the small stuff. We try keep at least one completely torn down keg + all engine accessories in stock at all times. If we don’t have it, we’ll find it for you.

Used known good short blocks tested on our engine stand with videos of it running and videos of a properly executed rotary compression test AT OPERATING TEMPERATURE plus a video of it hot starting afterwards. Nobody on ebay does this, don’t trust a compression test on a cold rotary - it test higher and doesn’t prove it will even hot start.

We can get your short block rebuilt to your specifications with all new rotor seals and all coolant seals / sealing kit. Depending on the complexity we’ll get it rebuilt here or with one of our local trusted / proven engine builders, and then we’ll test run it before shipping it to you.

We can get you a replacement motor or rebuild your motor with any parts you want to send us for zero parts mark-up. We can outsource complex machine work to proven rotary experts whether it’s porting (big street, Semi-Peripheral port, Bridge, half-bridge) or you want to strengthen the internals (optional dowel pins, 3mm apex seal machine work, etc.)

We will buy your short block or long block and help you ship it to us.

We pay you a base amount for the non-compression surfaces core (everything but the irons, rotor housings, rotors)

And then we can either work out a price and pay you before you ship it to us, or for the most money for your core, ship it to us and we’ll video the teardown and show the condition of every single part and pay based on if it’s re-usable and whether it’s an A, B, C, or F grade (F grade parts make a nice coffee table engine or wall art if you want us to ship it back to you).
