Trackspeed NA/NB EFR Turbo Kits - Currently Not Available
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!

I'm getting off topic and speculating, but even FM recently stopped offering standalone units either due to 1) declining sales or 2) legal issues. I doubt Savington or anyone besides FM could justify the expense and time to make an NA/NB kit + engine management to be CARB legal. And FM already has the market cornered. If you need it to be street legal, your best bet is SB-100 and go Exocet or some gray area shenanigans (smog hookup or non-smog county).
Back on topic, congrats to 949 and Savington for that ridiculous dyno plot. Please bring this to MRLS and give us all rides.
Looking for one-stop shop for turbo package, not FM (this time around). Bonus points for no cutting of engine bay or drilling of holes for intercooler plumbing...

I ordered my TSE kit with the 6258 today. Along with it, I'm getting the TSE MS3, DW200 fuel pump, flow force 640cc injectors, and their 16 row oil cooler kit. Very excited to get my car back on track with all these new goodies.
The dyno plot from above, in action.

One of the side effects of popularity and success is scarcity. Sales have been roughly ~2x what we expected them to be this spring, which I am hugely grateful for. If you are waiting on a kit, I am expecting everything to ship by June 20th. You may see some of your parts before that date, so as always, keep an eye on your online account for tracking number updates.
I recently picked up one of your kits and have a question. Would there be any negatives if I get your turbo manifold extrude honed? There are some casting blemishes on the inside of mine that id like to clean up.
Is TSE still planning on releasing an intercooler kit with piping?
e: should add I've been holding off on my order in anticipation of the full intercooler piping kit.

I would stop holding off, though - the price for the entire kit is going to jump when the IC pipes are added. You will save money by buying a kit + IC now, and the pipes will be made available to DIY customers at a discount when they're ready.

Small tweak to our EFR stud kits. Without a good slathering of Resbond, we have seen studs occasionally come loose from the manifold and wind their way out, even though the Stage 8 nut stays in place. The long-threaded portion was long enough for the stud to back completely off, which resulted in the loss of the entire stud and nut.
Moving forward, all the kits will get our new V2 studs, which have a much larger center shank. This shank will stop the stud from fully backing out should it come loose from the manifold.

Coincidentally I caught mine just last friday night during a quick check up before a early morning back road drive. Two studs had backed out; one was literally hanging by a thread. must have not used enough Resbond! glad to hear I'm not the only one though.

Coat all of the threads completely, not just a single line like you would normally use. I also do the nuts as well. There's plenty of Resbond included with the kit to do all of them without running out
