Trackspeed NA/NB EFR Turbo Kits - Currently Not Available

Trackspeed Engineering EFR6258 kit with "Medium" waste gate actuator
Another dyno from Bullet. Stock BP4W head, ST double valve springs, forged internals, squaretop, 3" exhaust, E85. 23-25psi
Low line is the map from the last Supermiata event we ran at ACS, 220whp. This is our spare motor for UTCC/Hyperfest in a few weeks. We'll swap in a whammy engine, +2 CNC BP6D head, cams, coatings, etc. That one should make another 30-50whp we think.

I finally got my Trackspeed kit installed and my car ready for our first Time Attack event of the year. Cars are classes by power to weight ratio. I have to give huge props to Andrew on this kit, first event out and my co-driver not only won our class, but set the fastest time of any street legal car, even those on Hoosiers. We were on 245 Maxxis VR-1s. We never turned a wrench and only fiddled with tire pressure...what an amazing kit! Car was running 8 lbs. of boost on E85 with the 6758 EFR to stay below our classes 9:1 weight to power ratio.
FYI...I run the Flyin' Miata silicon intercooler piping and it works beautifully with the TSE kit for those waiting for a final solution. I run the Treadstone TR6 intercooler with the inlet and outlet towards the bottom of the intercooler, I don't think the FM pipes would work with an intercooler with the inlet and outlet in the middle.

Gents, respectfully, please start another thread to discuss using FM's piping. Our piping kit will be out shortly and I don't want to confuse anyone who reads this in the future.

It's easy to lose sight of just how freaky this turbo is. This is the same turbo we're using on all the S1 cars (Bullet included) and they spool instantly. Like, better response than a GT2554R above 3500rpm. The whole focus of the kit, in fact, was on optimizing that spool. We knew they would make the power on top regardless, but god damn. 400whp from the smallest turbo available.
So wild.
So wild.

Those numbers are just so friggin wild!!
I'm building an HPDE car, not a race car, and I've been eyeing this kit for awhile. Is there any chance a version of this will go out for CARB approval (when a full kit is finally developed)?
I would LOVE to have a street legal track car with this turbo kit, but living in CA really puts a damper on certain go-fast bits. I would happily pay the premium for this kit vs something like FM if it was offered with an EO sticker. Just wanna let you know Savington there's demand, and I guarantee I will put my money where my mouth is. lol
Keep up the great work!
