Good advice, especially on Mike - he has a thread somewhere on here (older) on the 335. I think I remember reading that it's a much bigger unit and thus loads the engine more to power it, which increases stress on the motor to reach a certain power level. Translation, a 335 unit might bring you closer to the point where you'll need to build the motor for FI. Realistically, if you don't have E85 and you're new to aftermarket FI (not saying you are necessarily) then you might want to lower your expectations to somewhere around 250+/- on pump gas with the Sprintex units. Still will be plenty quick btw. Going about that without E85 requires a lot more complexity and you're pushing the limits of the blower at 300 whp.

Additionally, I would recommend clutch, vents/vented hood, ceramic coated header at least, oil cooler, pcv catch can, coil packs, heat reflective tape on the intake pipe, and the Perrin Intake to mitigate the heat soak.

If you don’t already have the kit I would recommend just jumping up to the 335 kit. Get the 90 or 85mm pulley and it’ll leave you at 300/300ish (this is more than then 300/240 top end of the 210 kit). You will just need clutch, FP and injectors; the other parts I mentioned would also be highly suggested, as well as e85/WMI.

Lastly, get a good tuner: I am tuned by Mike from Moto-East (now Xero Limit) and he probably has the most experience with the Sprintex Kits. Otherwise, Bill at Delicious or Zach at CSG will be your next best bets
