Injector reference for the Lotus lineup: 2ZZ-GE Elise and Exige, supercharged Evora and Exige V6, the Esprit four cylinder and V8 twin turbo, and the detail your dealer will not lead with: the US market cars run ordinary Denso injectors on Toyota engines. Compiled by the injector cleaning department at Boost Lab, Inc.
Every US market Elise and Exige from 2005 to 2011 runs the Toyota 2ZZ-GE, and the Evora, Exige V6, and Emira run the supercharged Toyota 2GR-FE. The injectors are Denso units with standard Toyota connectors, the exact hardware family that crosses our bench every week from Celicas and Camrys. Supercharged Exige S and 2-Eleven cars run 440 cc Denso injectors from the factory. The badge is boutique, the dealer network is boutique, but the injector service is not: cleaning and flow matching a Lotus set is Toyota work with better documentation habits, and it costs Toyota money, not Lotus money.
The service pattern is the collector pattern. These are second or third cars that sit through the off season on E10 pump gas, and a 2ZZ that lived at 8,000 rpm all summer then parked for six months is a varnish study. Cold start stumble, uneven idle, and lift point hesitation on the cam changeover get blamed on everything exotic before anyone flow tests four ordinary Denso injectors.
The Esprit is the classic side of the page: port injected four cylinder turbos through the S4 era and the twin turbo V8 through 2004, rare cars with a thin specialist network and injector sets that have rarely if ever been out of the engine. These respond to ultrasonic service like any port injector of their era, and on a car this scarce, documented cleaning of the originals beats hunting replacements.

| Upgrade paths run through the Toyota aftermarket: flow matched sets of four for the 2ZZ in common sizes, including 850 cc Denso units (ref 1001-87F90A, 12.2 ohm, factory Toyota connector) and 1000 cc options for forced induction builds. | ||||

Elise and Exige injectors varnished from winter storage, cleaned and matched back to within a couple percent with before and after documentation. The lift point feels right again.
Exige S and Evora sets flow tested to confirm the boosted engine actually has the fuel headroom the tune assumes, before the tune assumes wrong.
Four cylinder and V8 Esprit sets that have never been serviced, brought back with documentation. On cars this rare, the original injectors are worth saving.
For US market cars, yes. The 2005-11 Elise and Exige run the Toyota 2ZZ-GE and the Evora family runs the supercharged 2GR-FE, all with Denso injectors on standard Toyota connectors. Supercharged Exige S cars use a 440 cc Denso unit. It is the same hardware family we service constantly from Toyota applications.
Storage varnish in the injectors is the most common cause. These cars sit for long stretches on ethanol blend fuel, and deposits form in injectors that barely accumulate miles. A flow test of the set of four identifies it in numbers, and cleaning typically restores factory flow.
Yes. The port injected four cylinder turbos and the V8 twin turbo use conventional electronic injectors of their era, which respond well to ultrasonic cleaning and resealing. Given how scarce Esprit parts are, a documented service of the original set is usually the smartest path.
The Toyota aftermarket covers it: flow matched Denso based sets of four in 850 cc and 1000 cc ratings drop into the stock rail with the factory connector. As an authorized Injector Dynamics and Fuel Injector Clinic dealer we can also spec and flow verify a set for your power goal.
