Yeah I've got a stock VVT Exocet that is an autocross toy. I want the most responsive turbo possible.

Have you actually driven a well tuned vvt 6258?

Asked a rep about it at SEMA 2018. It's shelved indefinitely, no ETA. They are focused on Gen2 EFRs (8474, 9274, 9280) instead.

If you want response, buy a 6258 kit from me.

That was my plan before I heard about the 5951 and now it is my plan again
Do you know if anyone has installed it in an Exocet? Fitment issues?
I hadn't seen that info from SEMA 2018. I've got megasquirt, flex fuel, and clutch done. Injectors, exhaust, gauges, ignition, intercooler still on the to do list.
What are people using those ridiculously large turbos for? It's surprising that there's more demand for those than the 5951.

A quick search will get you the exocet answer. As for bigger turbos people run the 6758 to get into the 450hp range and a handful of insane people run the 7163 to get all the horse powers

They use them for six and eight cylinder engines. My buddy with the rb26 GTR is giddy about them.

But those engines have two turbos! Is 1000+HP really necessary? I guess this is why I drive around cones in a parking lot instead of playing with the big boys. Haha.

Yes that power is always necessary. There is never enough power.

I know, I guess I forgot which forum I was on.
My goal is to have enough power to be traction limited up to 70mph in 2nd gear on 200TW tires (5spd, 3.6 rear end).

You may want the 6258 to hold 200 to redline

200lb-ft at 7200rpm is 274hp so a smaller turbo would probably be optimal. From what I gather though the EFR6258 is better in every way compared to smaller turbos like the GT2554R.

274 at the wheels, you have driveline loss to account for. Sav's e85 CNC VVT looks to be pretty much 200 @7500.
