injector and regulator help Im switching over from carb to efi and alittle confused on the injectors and regulator.Im wanting to make 800 wheel hp on e85 using a truck style intake and stock throttle body.At least thats what alot of people said I could do.I will be running a terminator x 550-903 system so if the I know theres holley and bosh in the pulldown mensu.MY question is finding the injectors and regulator.I was told bosh 210s but when I go on ebay theres like so many injectors and price.Im hoping to stay around 600 dollars for injectors if possible.Im going to use a 4304 fuel pump as well.If anyone has any part numbers or adds etc for injectors and regulator that would work would really appreciate it.thanks in advance

You can set up a "custom" injector, as long as the supplier gives you a good data sheet its no big deal, mine are not in the list, but I googled the part number off the injector and found the data (Turned out its a stock flex fuel 33 lb... ) that matches the flex fuel injector in the menu.. before I figured that out I just used the data off the internet.
I cannot recommend enough,, BEFORE you buy your terminator, READ all the manuals for the stuff your buying from holley, you can download them off their website under each part number display or under support.. The Terminator only has 1 O-2 sensor, and only a few available IO so count up all the accessories you think your going to run, power adders etc ,, you may need the can bus expansion module. (Pro dash has extra I/O) but ther is a tip-over point where a Dominator is easier and more economical and needs less external parts.
Example: I wanted sport shifting, that's 3 IO points, of 4 available. I'm running trans pressure, another I/O and I want AC cut, another I/O point ,, the simple stuff adds up. I went with the 7" dash which can have gauge points but no active points, it doesn't feed data to the terminator ECU only reads it. It was cheaper than a full set of Autometer or other name brand gauges. it needs a special cable or you run the can expander and get reall I/O points added , the cable is 150 bucks the Can module is like 380 unless you find a deal, Holley does MAC pricing on terminator so the prices don't vary much.
Good luck.

The Term. wont run low imp. injectors, so you might be better off using one from the drop down menu,
makes life easier. I dont know what length injs. guys are using on truck manifolds, as far as what's on the drop down.

I was told earlier that the bosh 210s were a option.I went on ebay and there are so many what seems like different bosh 210s is a reason for my confusion.You can get a set of 8 for like 200 dollars up to 600 dollars so I just wasnt sure what to use.I see holley has some injectors for 599 and vsr racing has some for about the same price.I just want to make sure I get the right ones and was hoping maybe someone on here has tried it before...thanks so much for the post

a local guy here just bought the snakeeaters and hes having a ton of trouble with them.Im not sure what his issues are so far but hes been doing the ls stuff on a budget for years and years so the injector stuff isnt anything new to him.We have another local guy running the bosh 210s and he likes those is the reason im kinda looking at those and they are on the drop down menu.I appreciate your post and thank you

I looked up the holley 160s and I think they are low impedance.I thought for some reason i had to use the high impedance injectors I run the holley 550-903 terminator on my car
Holley recently came out with a 150 or 160# high impedance injector, FWIW. No idea on cost.
No idea what HP my car has, but it's a touch over 4000# and foot-braked, it has trapped 146-147 mph. That should be somewhere in, or real close to 800....
I had SEP1000's, which worked great, but w/dual 450lph pumps, they were datalogging like they were maxed out.
Switched to SEP1500's, and car ran like crap at anything other than WOT. 3 were bad out of the box...
They replaced them, but I chose to move on and not risk the whole bargain basement injector thing anymore..
I grabbed a set of Bosch 210's from VSRacing, which are in your price range, and the car has never started, idled and ran so well.
Out of the 3, I'd only recommend the Bosch 210's
FWIW, All three are in the drop down menu of Holley Terminator X
I do run E-85, usually in the 78-80% ethanol content area, and on car's best pass ever, the injector duty cycle was only 51%.
Again, that was with 80% ethanol, which requires 30-ish% more fuel volume to make the same power.
On gasoline, that duty cycle would "probably" only be 35%, give or take...
My point is, I didn't see any mention of what fuel you'd be running (sorry if I missed it), but as 3 window said above, you'd be fine with pretty much any of the Holley or Bosch injector sizes that have been mentioned.
Also, some say the 210's aren't good choice with a gasoline only setup, but although they are definitely bigger than he'll ever need, we run a set on my co-workers turbo 5.3, and it also starts, idles, and runs great.

I'd highly recommend NOT buying your injectors (of ANY brand, or alleged brand) off of Ebay or Amazon.

I bought the VSRacing Bosch 210's and installed them on my 5.3 (VSRacing S480 Turbo w/102-92 turbine) using the ID2000 data sheet, administering the pump e85. Starts right up, idles perfect and easy to tune with HPTuners so I'm sure they'll be fine with the Holley. I'm using the stock LS1 intake and Fast Rails so I had to use the little injector 'hats' to get the length right.
