Whats wrong with the factory injectors?

the stock ones are actually stuffed Its not that i am replacing them for better capacity injectors or anything, just ones to replace the aged ones.

Ahhhhh.

When you say stuffed how exactly?

Have you sent them away for testing/cleaning?
(Cost me $40ea to get them cleaned and new seals filter thingees put through them, I had an 18RGEU also and the injector dood said they took a little while to get going on the machine)

If its been sitting around awhile they may just be gummed up and need a decent clean.

Unfortunately I don't know of any suitable replacements.

i used 22RE injectors on mine with factory ECU. Seemed to work OK - however the factory ECU is a POS dinosaur.

I upgraded to a megasquirt and found 10% more peak power, 25% greater fuel economy, and had a MUCH more driveable engine all round

i've gone from the std 210cc to 240cc no problems
your basically looking for top feed, low imp, square plug (EV1 plug)

i went from 240cc to 360cc does not like it a bit, with std ECU.

blue top 4AGE injectors are the same size.

1st gen Integra DOHC uses 240cc's and are direct fit(black top Kleins)
great upgrade when using high comp pistons, bigger cams, ported head, etc...

If you're running aftermarket ECU (so impedance and plugs doesn't matter), is there anything stopping you from running other top feed injectors, like 1G etc? Are they the same physical size?

pretty much my setup now. sounds nice and torquey. Test drive to come.
