Hello a few buddies of mine started this project when I met them about 4 years ago ,a RB powered Miata mx5 !!!

at first we installed a rb25 neo motor had to do allot of r&d and we went 9.8 @ 143 in the 1/4 mile. while all that was going on we had been working on a rb26 building it from head.to toe! The car now has a RB26 fully built with a powerglide 2 speed gearbox,GM differential,custom made axles especially for this car from the DRIVE SHAFT SHOP AXLES,a pair of 26x10.5 Mickey Thompson full slicks , Garrett gt42-45R dual ballbearing turbo,c16 race fuel,26psi making over 800hp and 600+ ft.lbs.tq

let me know what you guys think!

this was our 9sec pass On the 5 speed manual gearbox (still had the rb25)

This was our first pass on the powerglide gearbox we didn't know how the car was going to react we wanted to see what it did so we could dial in the launch and everything else after

We were so happy the car did so great on the first pass!!!!! (RB26 set up )the car is capable of doing 8's , the 15th of January we are going to import face off here in SoCal we are definitely going 8's !!!!

Hmm thats a very interesting conversion. Its amazing how many different engines have gone into mx5s over the yrs. I personally would've gone a TT Lexus quad cam. But hey each to thier own :)

No I wish lol the motor wouldn't have let us put the radiator in ,we wanted the radiator to fit and not have to cut the crap out of the front so we cut 3" off the firewall to make it fit better,and it actually worked out very well and were very happy with the outcome! The 15th of this month is import face off here in SoCal,hopefully we can hit the 8's,were very excited about it! Its been a long journey to be where we are now alloy if sleepless nights and R%D. I will be posting up the videos for sure for you guys entertainment!

    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny  
    • Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now. we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck.  so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again 
    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
