Injector upgrade thoughts.

If we were to change the fuel rail to a type that doesn't have the built in regulator is there a "wrecker option" regulator available, does anybody know?
How do the commies and falcons regulate their pressure?????

They have fuel pressure regulators on the fuel rail that will not "drop into the jeep fuel rail".
The ford one runs the same pressure as the OBD1 jeeps.

I think that blanking off the back of the fpr void, on the stock OBD1 fuel rail, so the fuel runs straight out of the rail and into a off rail fpr, like what is common in aftermarket turbo applications would be simplest.
Don't know of a stock off-raill FPR setup that you get at a wreckers. Would also have to establish the fuel pressure of the off-rail FPR.
You could also get an aftermarket adjustable offrail fpr, but for the money & time it would be cheaper just to get the 49PSI Chrysler regulator shipped from the states.

So the Falcon injectors run at the same pressure as an OBD1 Jeep????

So where did you guys buy your neon injectors from, the best price I could get in NZ was $600 EACH!!

in the first post
"Handy links:
Most of the injectors mentioned above can be bought reconditioned for about $25 usd each, here:

Thanks to this thread instead of cleaning my injectors I'm ordering 6 upgraded ones from the US from eBay:

There's a video on that page that shows the difference between the stock jeep injectors and the newer Bosch ones, pretty amazing difference.

I think fuel economy of RAINMAN’s car actually is 10L/100Km to 11L/100Km since speed sensor installed on output shaft of trans.

The reality travel distance is about 13.4% more than displayed on the dashpot since changed the differential ration from 4.10 to 3.55.

dude there is no way my heap gets that sort of economy.
At the moment it is getting 14.5-15 l/100 km. spedo is right with the 410 ratios & 32" tyres checked against a gps.
