Fuel Injectors

justin1642 · 01-31-2007, 06:18 AM

i am looking for 550cc injectors and i need to know what are the best websites for the cheapest injectors. i know rc are good but they are $550 or more i want cheaper. i see venom on ebay all the time but i heard they are never right on they need to be flow tested before you put them in. so any help will be appreciated thanks.

well more fuel isn't going to make your car run any faster unless you have higher volume or maybe a really high boost. I'd say if you pay more than $250 your getting robbed. They function the same as regular injectors its just they allow more fuel during the injection pulse.

well i am going to do the lexus upgrade i have the afm and just need the injectors to complete it so i need to know where to buy some cheap and effective injectors that won't blow my engine.

I have RC's, I wouldn't run anything else. Especially venoms. If one of your "cheaper" injector fails your motor could follow close behind. Not worth it IMO, buy new RC injectors or used RC injectors and get them flow tested. How much will it cost to rebuild your motor? You might get away with it, but why chance it? Your call.

also i just got done talking to my friend he has an 88 rx-7 turbo and he has some 550 injectors from that, that he's not using and said if they work he'll give to me. so my question is will they work on the 7mgte.

are those injectors plug and play?

or do i have to splice and dice the wiring harness?

if so do they sell the clips i need for the injectors to fit my supra.

thanks

well i know they do sell clips for the injectors

There is high impedance and low impedance. I think the Supra's use the low, maybe not all, but at least my 87 Turbo does, so check on that part too. The injectors I mean.
