The OEM kit.....don't bother unless you absolutely need CARB approval. Ditto to what Turbophun stated on the MP45 SC. The OEM kit, when I inquired from my local Lotus dealership was around $6-7k and didn't factor in the installation costs. Keep in mind my prices are dated as I checked into this back when the Elise SC was first released and they were offering it as a factory upgrade to the non-SC'ed cars. Wasted money in my opinion when their are WAY better options out there.
I run a Katana 2 ([email protected]
est. 245bhp), even tho it is a great reliable kit and provides lots of fun....these days I would go with BOE. When I snagged mine from the now defunct Sector 111 (Shinoo's new company sales it https://www.inokinetic.com/lotus/kat...ategory=Engine
), it was only $4500 back in the day. It is now $6k for the same kit. I would go with the newer TVS SC's that BOE provides. They make more power and is upgradable for the same price as the Katana.
