Correct injectors? - ZR-1 Net Registry Forums

Jaap · 03-12-2015

Hi,

Need some help, we`re working on the LT5 engine and have some doubts about the injectors. Is type number 2631 01D36B the correct injector? They`ve been replaced in 2013 but the engine just run 300 km since the engine had an overhaul en injector replacement. Some how the injector from cilinder two gone bad.

01D36B is correct, but what means 2631?

should we replace them or clean ultrasonic and test them?

thx
Jaap

They are Delphi , the car is a 90. # id on the injector is 01D036B. On the info I could find they are produced by Lucas in 1988.

Yes looks similair

Same number. I wouldn't worry about the 2631. Could be date code or something else. Can you have them flow checked?

No Bosch injectors, it`s a 1990 ZR1

Yes, I understand. The Jegs parts catalog shows that the FJ10024 injector is the correct injector for the ZR-1. http://www.jegs.com/webapp/wcs/store...ductId=2413192

Tommorow they will be flow checked and ultrasonic cleaned.
The strange thing about it is dat some of the plastic has been filed of, you can see it in the first picture..

Is that a commom thing to do?

The question is what are the correct voltage offsets for them.
