help ID Injectors
 

Hi Gang,
I'm doing a bunch of medium work projects on my upgraded 10AE. Among engine stuff, it's supposed to have improved injectors. Touble is, I'm not clear on exactly what size they are. So, as long as I'm tearing stuff off the engine (i.e. exhaust for wideband installation) I thought I'd lift the UIM and see if I can find out exactly what injectors are there.

Anyway, I've attached pics of the primary (red & black one) and secondary. Can anyone here tell me what size they are?

If not, I'll pull one each, but was hoping to halt disassembly here if someone here knows what these are.

Thanks!

Thanks for the suggestion. I took a closer look at the primary, and can see part number SL4-750. Looks like these are 750cc. Correct?

Howsabout the secondary? Any ideas on that one?

Okay, so I sucked it up and removed the secondaries. Here are closeup pix on my bench.

Can anyone ID these?

Okay. So I guess I should work harder before I post. Looking (with my reading glasses) I can see teeny-tiny numbers on the red top - 95500-1370. Google search found some on eBay described as 550cc.

So, in the interest of getting some information I couldn't have found with a bit more effort on my part (as has been the case so far) I'd like to ask your opinion on this setup on the following:

Atkins rebuild with port & polish
Racing Beat Rev-TII exhaust
Microtech LTX12 ECU
MSD Blaster SS Ignition Coils

Does 750cc primary & 550cc secondary make sense for maximum performance?

THX!

.You have stock 550 and RC 750 as secondary.
550 and 750 would be good IF you had a way to control the 750's
like have an SAFC,or RTEK.
SL4-750 is a saturated injector.
I'm running PL4-750's with an Rtek.(they are Peak and hold injectors)
.....
as far as the setup you just typed up,There is no Turbo mentioned.
The Fuel is OK,you don't need the Coils,The Exhaust is Kind of heavy if it is gonna be a Track car.,but it sounds great! Just the exhaust weighs about 80 pounds,seriously.
The ECU: do you know HOW to tune a Microtech?
Trust me You are gonna have to Research what you are doing in terms of modification as it may just turn and bite you in the ass.You can't just throw parts on and expect it to run Perfectly,unless you know what you are getting into.
I have had my car for 6 years,and Hell,I am still finding out shit!.I put on stuff that didn't Sync.,It was a Cluster-fark.I had to go back to stock and reconfigure everything.
