This is what the cross reference list gives me but there is no Bosch nr

A910E6941S Bosch (Ford) E5ZE Fuel injectors, primary (port) Ford T'Bird, Mustang 2.3L Turbo

The original injectors were made by Rochester. Do you have a preference for Bosch?

Rens,

Those Bosch injectors are 2.8 ohm peak and hold injectors. I'd check the resistance of the original injectors first. I would have expected them to be saturated injectors of 13-15 ohm resistance. If you guess wrong you'll burn out the injector driver in the ECM.

Double check the resistance, and verify the flow rate via the service notes.

Here's a link listing various injectors, part numbers, flow rates etc. Hope this helps.

Chaps,

Mine were all knackered (contributing to my melted piston) and I have got some Bosch ones on order from Marcus @ PUKEsprit.

They are correct flows etc and the mians are are matched to each other.

The primary injectors are low impedance (2 ohms) 370cc/min or 36lb/hr "peak and hold" injectors.

The two plenum secondary injectors are similar in construction to the primary injectors except they are actually high impedance (16 ohm) 190 cc/min or 18 lb/hr saturated type injectors.

Thanks to Dermot's site for the info......

There is an additional cross which is "SR 370" - these are the RC Racing 370 cc/mm ones that Dermot uses (there is the following note: The originals are Delco made and flowed out for the Lotus. Originals can be obtained from Lotus at substantially more cost. The above RC equivalents are exact matches.)

Don't know if that helps - all the info on injectors was copied from Tony Grasso's contribution to the Esprit Fact File.

If you can find anything else out then please let me know as it would be great to clear this up on the xref list.

Cheers, Ian

Also found this:

We are talking about using BOSCH injectors on all 89+ Esprit

4cylinder injected cars.

The BOSCH injectors are fully compatible with the GM MP4 (DELCO)

injection system on all 89+ DELCO cars.

The BOSCH Pintle type injectors are superior to the Rochester

(Delphi) injectors that come with the 89-95 S4s cars.

The Delco system requires low impedance "peak and hold" injectors of

36LB/hr or 370cc/min for the 4 primary injectors.

The SE's, S4, and S4s also have two high impedance (saturated)

secondary plenum injectors of 190cc/min. I chose to get 200cc/min

(19LB/hr) BOSCH high impedance injectors.

I found a source in California that has the correct injectors at a

very reasonable price.

http://www.fiveomotorsport.com

will sell a set of 4 BOSCH FORD E5ZE 36lb/hr low impedance injectors

for $188 with no core charge if you tell them its for a Lotus.

The secondary injectors are BOSCH FORD D5B 19lb/hr high impedance

injectors were $35 each, and he is willing to break a set of 4 if you

tell him that it is for a Lotus.

I am very happy with them. I bought them because my original

injectors were plugged.

I'm the one that originally wrote that above, and I believe I was the first to find www.fiveomotorsport.com as a good source for the Bosch Injectors. I use them in my Esprit SE and I haven't heard a single complaint from anyone else that has used them or bought them from Five-O. And they are much cheaper than equivalent injectors from RC.

Travis,

I agree I run Bosch as well.

In their defense the RC injectors are stainless (which could be important if running on alcohol) and individually blueprinted and match flowed, which may be significant for drag racers and Bonneville guys.

But for the mast majority of the applications out there standard Bosch injectors make the most sense.

Five-O will blueprint and match flow to 1% as well. Even RC will admit that the BOSCH is a great injector, though they will say that their Lucas injectors are better.

Rens,

can you let me know why you are going to change your injectors, how did you find out that your original injectors needed replacement. Did you already have an answer from Five-O ?

Yep

I've got them already

After changing and upgrading almost everything the last item was checking and cleaning my primary injectors

at the shop they told me that the spray wasn't good

that's why !

But call me
