Default RC engineering 750 CC high impendance injectors

set of almost new RC engineering 750 CC high impendance injectors, they have less the 1 mile on them!
I bought them from PlanoLexus http://**********************/PageView.aspx?PageID=1
they had installed it in a customers new NA-T car, but needed to go to bigger when the customer decided on a bigger turbo
They're direct drop in for the SC300/GS300 no resistor box needed, I didn't want to use a resistor box as it's one more thing that can go wrong (plus I've heard of 2 cases of them failing; since guys are using used resistor boxes)

asking $500 + shipping and paypal
or $500 cash picked up

I'm guessing you mean 500 at the crank?
I was told the best size for that would be 650cc, but I was only able to get 750 cc at the time,
figure I would lean it out with my AEM

I just checked the RC site and used their calculator

http://www.rceng.com/technical.aspx#...tor_Worksheet_

and basing the calculation on the following
HP desired at crank 580 (which is about ~493 to the wheels, assuming 15% driveline loss)
BSC of .60
Duty cycle of 80% (which is considered safe, even tough I see guys on here run it to 90%+ )
fuel rail pressure of ~45 (if you use the Supra TT pump)

the injector recommendation is 749cc!


Mind you the RC recommendations are on the safe side,
you can check Supra forums for this huge thread about Duty cycle (think there was one here too a long time ago)

PS the fuel rail pressure of ~45psi is when you use the 14volt mod
with stock 12.7 voltage you only get ~40psi

I dunno why people risk using injectors with a resistor box. it's one more thing that can fail (and in a big way)
someone on Supraforums lost their engine due to the resistor box failing during high boost
(I'll try to look for the thread, email if you want the link)

ALSO you won't risk frying the ECU if the resistor box has a short (saw this on a skyline forum, it's also mentioned in the SF NA section)
