That would be the primaries and the secondaries are 190 cc/min high impedance.

One web site says they are Bosch the other says Rochester. Which is it? The injectors removed are RP. (Rochester Products.) How can they fit a T Bird or Mustang ? The SR370 GM part number does not match anything at the dealer. Ususally it is an 8 digit number. Remember this is an SE.

Windosr:

Take a look at RC Engineering (www.rceng.com) for injectors. They have a direct replacement that smoothed out the idel on my S4 (same injector as your SE). I increased the flow by 10cc per minute with the RC injectors for a little more punch.

The RC from WC Engineering are probably the best readily available injectors around although very pricey.

If you're looking for a more affordable replacement that's much better than the stock Rochesters, call these guys. Price is great. I just fitted them to my S4s which is the same as your SE.

The E5ZE for primaries as listed above, not sure of the number on the secondaries but they can tell you.

There are not that many types of injectors in the world, and Lotus doesn't make them of course. As for how can they fit, well, they are rated in pounds per hour (domestics) and many cars use the same injectors. I'm a Ford guy and you can just know the colors to know the flow - orange 19 lb, blue 24 lb, 30 lb I forgot the color, 36lb brown, etc., etc. You can find replacements for your Esprit for not much cash, I am certain.

As for high flow, you don't need it. The car with the stock fueling system is more than capable of being overly rich as I've mentioned before and have shown true through lots of dyno testing. Having new injectors might smooth out your idle a bit, but it won't be because they are high flow, it'll be because they're new and have good spray patterns and are flowing like they should.
