Injectors

will second gen 12 valve injectors work in an intercooled first gen?

RSWORDS · #2 11-20-2009, 10:31 PM

No. Couple reasons why. First the injector line nut is teh wrong thread, 2nd the pop pressure is off and finally the spray pattern is not perfect. You can put 2nd gen nozzles on 1st gen bodies and reset the pop pressure to work with teh VE but you still have a funny spray pattern.

The spray pattern on the '91-98 intercooled 12v engines are the same 145°...

so putting the nozzles on the bodies would work, but what would be the downfall to the different spray pattern, if there is a difference. would the truck run ok?

I didn't know there was a debate.

I was under the impression that the spray angles were different on the 94 up trucks. I read that everywhere.

I thought they were also Richie, Getting mixed storys from a few different respectable injector guys.

Smokem · #10 11-25-2009, 01:12 AM

The DSLA number designates the spray angle:

'89-91 DSLA155 P104 4x0.014"
'91-93 DSLA145 P265 6x0.010"
'94-98 DSLA145 P464 5x0.009"
'96-98 DSLA145 P477 5x0.010"

This should clear up the confusion.

RSWORDS · #11 11-27-2009, 11:31 AM

How about 89-90 injectors?

Check the edit on post #10.

Ok so its only the non-I/Ced injectors that are different. Good to know. Thanks for clearing that up Weston!

I think the confusion is when someone uses a stock marine tip ( 370's and 435's ). Those are the ones with a different angle due to a industrial p pump having a different piston bowl. Weston, are we getting warmer??

Smokem · #15 11-29-2009, 07:52 PM

The 435 is not a Marine nozzle, it is just a slang term given to the hone size 5x0.014". I have only read where the 1st Gen nozzles were 4x0.012" and 6x0.009", however that is not the case.
