Bosch 1000cc injectors on an Evo - Page 2

The EVO is no different than any other engine, the hundreds of other happy customers that have had excellent results with them should give you a pretty good idea.

Do the stock injector plugs work?

I think that they need an adapter plug on the injector side, which some of vendors have in stock. Then it matches your factory wiring without any cutting or changes.

If you get it with the adaptor pictured on the other page then it does.

The adaptors are $7/ea as an upgrade over the connectors that come with the injectors.

Tony im interest to order all 4 Injectors for my Evo with New turbo upgrade.. so My tuner will open resister box something?

A saturated injector can be used in place of a peak and hold type without risk of damaging the drivers, but not the other way around.

Whomever claimed that upping the fuel pressure was a good idea should be bent over and spanked. It is not a good idea, and that has nothing to do with the injectors. The best idea is always to maintain the manufacturer's specified injector pressure differential.

That was me, ask tony what his base fuel pressure is before he adds 50psi of boost :P

I suspect that is because Tony relies upon generating somewhere north of 900whp for his drag car, but has an injector rated at only 1000cc. He has no other alternative, except to use a different, larger injector.

Increasing fuel pressure for most here however tends to be a losing proposition for several reasons, some of which may not apply to Tony or other high hp drag setups.

There appears a communication gap here.

Bosch didn't rate the capacity of this injector at 105 psi of base pressure.

For 99+% of us here with in-tank Walbro pumps, raising base pressure is a losing proposition, for reasons which are well known at this point in time.

I'm not sure if you understand. The injector's rated capacity is specific to a particular pressure. It isn't 116 psi.

And regarding that Bosch pump, what happens to its volumetric capacity as it is asked to deliver greater pressure?

I'm not knocking the injectors. I haven't heard anything bad about them. I'm just stating in general that so long as injectors are properly sized, there is nothing to be gained from raising pressure, but there are potential drawbacks. If the injectors are undersized, such as these would be in my application, such drawbacks are inevitable if not considered.
