2.5 vs 3.0 injectors

Post by TEM »

Hi,

My rebuilt engine has just been started for its first time - idling smoothly and without vibrations :D Only problem is the leaking injector rubbers...

Are the injectors from a 3.0 interchangable with the 2.5 injectors? What about flow?

I guess I need bigger injectors anyway - the engine has balanced & polished rods, crank etc - JE high compression pistons, Cat Cams, ported polished heads, bigger valves etc....

Currently running stock L-jet - but will install aftermarket fuel injection as soon as i can afford it. Just need to drive the car from the shop that has restored my GTV6 and put it in winter storage.

Any suggestions to suitable injectors?

My car slowly coming together: http://home.chello.no/~alfator

There's a Jaguar XJS, IIRC, that is higher flow and compatible with the L-Jet and fuel rail. Some one I knew had researched this for his '84 3.0ltr build up similar to yours. It's a mid-80's model.

BTW, isn't the flow rate in stock configuration 19 #'ers?

Greg's info states the stock injectors at 17.6pph @ 2.5 bar. That's basically what I was thinking. I'll want to increase the injectors when I do my 3.0 build-up.
