what injectors to use??

[TOYROTA]

im building a 7agte for my kp60 and im just curious as to what would be a good injector to use also what cc?
will go expensive aftermarket a bit later however would there be any other descent interchangable ones that i can get off other cars?

[big_boy]

i can sell you some 7M ones cheep 303cc

[TOYROTA]

are they bigger than 4agze ones, also do you know what boost/hp can thay support up to?

no GZE's are 365

Not enough.

It's kinda hard to suggest an injector without knowing what sort of power you are expecting etc. I'd say if you are going with a 7AGTE being turbo'd etc you'd want a minimum of a 400cc/min injector in which case a 440cc/min out of a 7MGTE would suit just fine. In saying that I'd say anything up to a 650cc/min injector would be ok unless you either chasing heaps of power in which case you may need larger or else if you aiming for bugger all power you may need to go smaller. Whichever way you go obviusly make sure the rest of the fuel system is up to spec.

IIRC 500cc/min will supply 100HP

Good ones ive seen working on 4ages are 4agze, sr20det and rx7 turbo injectors.

My 4agze injectors were flowed at 430cc across all four. The guy that did the work (petroject in albany) said he got a similar result from the last 4agze ones he did,

That's not a typical result then as I have done at least 3 sets of 4AGZE ones at work and they were all 365 +/- 10.

I will look for the results sheet but I was suprised at the ratings. This is at full duty cycle at 3bar, not at 80% cycle as typically quoted.

Yeah thats what we test at too. Wide open and 3 bar ( about 45psi ).

not at 80% cycle as typically quoted.

That will be why my 440 side feeds flow 500 and my 550's flowed 600.

I flowed my 365s and worked them out to be getting pretty close to 440. I could have been working it out wrong from the ms and rpm setting on the machine though. All were exactly the same

[Caveman]

Well I had a look for the flow sheet but ive lost it You'll just have to take my word it was 430cc with all four within 99% of that.
