Dude this is amazing. I'm about to buy a terminator stealth x kit and I was unsure if you could replace or even upgrade the injectors! This is great thank you!
Thanks for the video. Nice to see how the throttle body is set up before I buy!!!
Let me know if there is anything else you’d like to see. I try to come up with videos based on common questions I get from customers, but I’m always looking for opinions of what to do next.
Does this x have a spot for a map sensor on the front side (Holley info is super vague on this) really like the shape of this TB vs the older stealth and ability to run an oem air cleaner base with locating tabs
There are 2 options for a map sensor on the front. There is a small 1/8” vacuum port then there is also an 1/8” npt plug you can remove and put a fitting in for another vacuum port.
Will this also work with the sniper stealth 4150?
Yes, the Sniper Stealth is basically identical as far as that video goes.
Now can you swap injectors to a higher flow rate to support alcohol engines?
It is possible to go up to 205 lb/hr. I haven't found anything higher flowing than those that I can confirm 100% they will drop in and plug in. I am sure you are aware that alcohol can be hard on the aluminum so it is good to flush it out after every track day. It can also be hard on the oxygen sensor. I have heard of some people having good luck with the harsher fuel like alcohol, but I would definitely expect to replace it once a season.
Great video! I was wondering about upgrading the injectors on the terminator x stealth since holley says the injectors can’t handle e85 and I would like to be able to run it from time to time.
Technically the injectors are rated for E85, but for some reason Holley doesn’t list the throttle bodies as being compatible. Here is our link for the injectors, just be sure to select the 522-121X part number for the 120lb/hr www.efisystempro.com/sniper-terminator-x-efi-injectors-522-101x
@@DirtySideGetsDown yeah I noticed they don’t list them as e85 compatible now but they did in the past and you can even find the info out on their forums. I’ll get with you guys before I place my order for the terminator stealth. Thanks for the help
We can also upgrade the Terminator X Stealth before sending it to you. Saves about $100 if we do that since we keep the 100 lb/hr injectors as replacements. A lot of people like that option so it’s all done when they get it
Do you have something in the 140-160 lbs range? I need to support 850+ hp.
I wish there was, but I haven’t found anything between 120 and 205. The 205’s are stupidly expensive too.
I have the Holley Terminator Stealth system, not Terminator X. Can I upgrade the 80lb. injectors to a 100lb or 120 lb. injectors the same as the Terminator X?
You can, but you will need to use a wiring adapter. Those systems use an EV1 connector and there are no higher flowing EV1 injectors that will fit. If you use the 100 lb/hr 522-101X or the 120 lb/hr 522-121X you will need an adapter like this. a.co/d/fwrW2Iz The single piece plastic won’t fit.
@@DirtySideGetsDown Awesome! Can I get those injectors on your website?
Yes, both the 100 lb/hr and 120 lb/hr are here. www.efisystempro.com/sniper-terminator-x-efi-injectors-522-101x
@@DirtySideGetsDown I ordered them, thank you.
Does the wiring have to go back in exactly the same place!!! Or… will it be ok if the wiring connectors are on different injectors???
I would definitely try to get them back in the same locations, but it really doesn’t matter. It fires all of the injectors at the same time and the same amounts.
Does that also apply for the 8 injector throttle body???
Yes, 8 injector systems are exactly the same just double the amount.
@@DirtySideGetsDown I thought the bottom injectors were on until the top injectors were needed!!! Am I wrong??
@@robmotown1 All 8 injectors fire at the same flow rate and at all times. The only way to change that is to enable the progressive linkage setting, but that makes the 4 in the rear stop working till needed, not top and bottom.
Do you have the link to those particular 120lb injectors? I cant find them on the site.
We don’t have them on the site at the moment. If you want to send me an email directly scott@efisystempro.com I can get you setup with a set.

We have them listed individually now. Stock replacement and 120 lb/hr

Is the 120 the biggest you can go.
There are a few options, but it's a pretty big jump from the 120 lb. How much power are you looking to support and are you using E85?
@@DirtySideGetsDown no e85. I do have a turbo planned and I know the power can get up there pretty quick. I believe the 120lbs will put me at around 700hp. What is the optima duty cycle the terminator run at?
@@theshark2804 You should be able to safely support 800 HP using gasoline and not E85. Typically the safe duty cycle is 85%, but many people will push past that.
@@DirtySideGetsDown 800 with the 120lbs? Ok I’ll order a few when my system get here next week hopefully
A lot of Snier people can use this I'm sure
Thank you sir!

Dude this is amazing. I'm about to buy a terminator stealth x kit and I was unsure if you could replace or even upgrade the injectors! This is great thank you!
I'm actually curious if you could even go to a bit bigger injector on these stealths or is 120lb about the max?
You can go pretty much as big as you want as long as the injectors are high impedance with the short ev14 body. We actually have 210lb/hr injectors for them and a bunch of options in between.
@@DirtySideGetsDown do you have a part number for those injectors by any chance I'd like to order some!
The 120 lb/hr is 522-122X

The 205 lb/hr is 522-205
www.efisystempro.com/holley-terminator-fuel-injector-upgrade-522-205
@@DirtySideGetsDown
Would this part number work on the stealth units? 522-228XFM
Is it the same connector as factory or different or this injector can’t be used at all? I’m looking at this 8 injector unit to but on a big block with a F2
