About Mikado
THE B20A IS THE MOST SLEPT-ON ENGINE HONDA EVER BUILT.
Everyone gave up on the 3rd Gen because they're "too hard" to find parts for. We're changing that.
The B20A Isn't the Ugly Stepchild.
Welcome to Mikado Motorsport Supply. The B20A platform isn't just the "Not-a-B-Series" B-Series. It's the most underrated, high-torque motor Honda ever dropped. While everyone else is talking about H-swapping or struggling with a Frankenstein B20B VTEC, we're becoming the hub for the BA4 / BA5 Prelude platform.
We exist for one reason: we wanted a place to document our build and bring the B20A back to life. Finding parts to fit these cars is a nightmare—we want to change that and make the platform more accessible. That's why we made our conversion rods and our conversion harnesses.
There is no aftermarket. We are the aftermarket.
Built, Not Bought.
Mikado is really just us building our own cars and listing the gear that worked. We know the struggle of the B20A because we live it. We want to be that mate who "knows a guy"—sourcing the right JDM, AUDM and spare parts, and engineering the stuff that doesn't exist anymore.
If we put it on the shop, it's because we've already installed it and know it fits. No more digging through dead 2004 forum threads for broken links and Photobucket images.
We're reclaiming that "built in my garage from a box of scraps" energy while building a community of like-minded owners through free meets and socials.
Why Mikado?
It's been decades since the '90s.
We have tools now.
It's time to stop praying for answers on dead 2004 forum threads. We have manufacturing tools that didn't exist when these cars were new. We're taking it back.

Tested on Our Own Metal.
We don't sell what we wouldn't run ourselves. Our parts are designed here in Australia and tested on our own cars—if we have a problem, we figure out a solution. If something is listed on our site, there's a good chance it's on one of our cars right now. That's how we know it works.
No Gatekeeping.
Keeping these cars running needs all of us. We're ready to handle the cost of test-fitting and development, but all knowledge is good knowledge. If you know something we don't, get in contact—it helps us all. We're here to share the data, not gatekeep it.
If you're too stubborn to leave the B20A, you've found your people.
Built for the redline. Built for the night.
