advice on injector purchase.

[Chopped]

Well I need to upgrade my injectors and not sure what to go with. Want to stay high z but not sure I need Id2000 or fic2150 injectors really. Looking to max power around 700awhp. Right now I'm going to stay on pump gas but would like to move up to c16 in the future. Engine:
6-bolt 4G63 bored .40 over- Balance Shafts Eliminated.
coated Wiseco 9:1 C.R Pistons.
coated Eagle H-beam connecting rods.
ACL race tri_metal Rod Bearings.
ACL race tri-metal Main Bearings.
ARP L19 head studs.
Cometic head gasket.

Turbo:
Forced performance t4z88hta 67mm dual ball bearing turbocharger.

Transmission/driveline:
Stock rebuilt transmission from TRE
Stock transfer case.
Stock driveshaft.
Fidanza flywheel.
Stock 4-bolt rear differential, cups & axles.
Stock front axles.
SPEC stage 3 clitch.

Fuel:
JNZ 7 gallon fuel cell.
Aeromotive A1000 fuel pump.
4 660cc/min Fuel Injector Clinic (FIC) injectors.
2 billet Aeromotive inline fuel filters (100 micron).
braided fuel feed line.
braided fuel return line.
Aeromotive fuel rail.
Aeromotive fuel pressure regulator.

Thats a little info on my build to this point. I have tried a couple of injector calculators and I come up with around 1500cc to run a 90% duty. I have no experience with injectors of this size so I was really looking for some good solid advice on what my best options are. I wish to keep it streetable for now so a good idle is key.

FIC 2150's, Especially if you're going to be running pump gas. If you'll be running race gas only that'd change things a little. The injectors won't have an adverse effect on your idle when tuned properly. A good rule of thumb is to always overbuild your fuel system; This way you have room to grow later, if you want to. Personally, I wouldn't want to be running anywhere near 90+% IDC.

Also, you haven't indicated what you're going to use to tune this thing with. Link? EMS?

 

[Chopped]

Yeah my bad. I'm using ems version1. Would any other brand of injectors be worthy to purchase? I used to run detchworks in my 240sx before crossing over into the dsm world.

 

[FalleN4ng31]

Nothing wrong with Deatschwerks or Injector Dynamics. I ran 1300cc Deats' on my skittle for years at around 80% IDC with no issues. Basically any "known brand" is safe.

FIC makes nice injectors. I ran RC's for a while with good results, only 550's though, so I can't speak as to the higher flow stuff.

 

[stephen_gst]

i've never used them but i've only heard good things about FIC

 

[97_4g63t]

If you wanna stay high z you can run 2150s or 1100s. To get 700hp you would have to turn your fp up on 1100s. Here is the flow calculator off their page Flow Calculator

 

[Chopped]

Im not sure I understand the duty cycle on higher fuel pressure. If I ran say 1100 injectors and bumped my fuel pressure to 60psi (which seems very high to me) doesn't that increase duty % on the injectors still?

Mighty Car Mods fan?

 

[jed344]

I have had great luck with fic's. I have 1050cc fic's in my car.

 

[97_4g63t]

That's exactly why I just went with the 2150s. I have a tuner that does all my tuning and the car idles good with them. 700awhp is not gonna be easy at all. I hope you have really deep pockets and a ton of time. If you really think you are going to make 700 then 2150s, 5-550 then I would say 1100s.

 

[Chopped]

I'm aware of the level of difficulty to reach that 700awhp. Being kid free with a high paying job is going to work to my advantage on that. I have a coworker that is actually going to let me borrow a set of 1050s to try out, but I think I'll get a set of 2150s anyways. Eriktande Ive seen mighty car mods a couple times but don't understand your direction of the question.

CHOPPED!! is one of their popular slogans, Marty says it all the time. I love that show.

get the 2150's, and your stock drive line will not last a long time at 700awhp if you pull it off.
The Driveshaft Shop | Eclipse - Mitsubishi - Import Axles
The Driveshaft Shop | Eclipse / Talon AWD - Mitsubishi - Import Driveshafts and I hope your getting stage 4 transmission, or whatever there strongest one is.

 

[Chopped]

Yeah I'm considering live axle swap and I think I'm going to try the Jack's 2.2 hd tranny.

We have a Bosch 2200cc high-imp injector as well. Let me know if I can assist you in any way!

 

[Chopped]

How about fic or Bosch 1600s without driver on aem v1? Anyone get these to idle smooth? I never plan on e85 so these should be big enough. Unless I'll have more headache dealing with these than 2000cc high imp injectors.

 

[97_4g63t]

I called fic when I was going to make my injector purchase and they told me it would be easier to get a smooth idle with 2150 high z rather than 1600 low z. Give them or another company a call and see what they say. Have you read about the difference in high and low z? Here is a place to do some research. Frequently Asked Questions

I have personal experience with Bosch 1600s. They ring out around 5 ohms and are a nightmare to tune. With an AEM? Maybe its not so bad, but the stock ecu drivers just cant cope with them. I will say on WOT pulls they do the trick just fine and are rock solid. Idle and cruise was just so bad i couldnt take it anymore. Even had them flow tested and cleaned to make sure, didnt help one bit. The allure of cheap 1600s is tempting, but unless you have solid proof that they work with an AEM sys, dont buy them. $200 bucks down the drain. Ill have a set for sale along with a million other parts when i get my build started and get around to piecing out tons of leftover parts.

thanks for the advice. I can honestly say that im going high z with high z 1680cc bosch injectors and will give a full review once iinstalled and I start tackling the tune.

 

[boost97gst]

If its a true hi impedance it should be around 10-15ohms i think. If you have boschs like that then you're good to go, AEM or through stock ecu/link(w resistor box delete). The problem with most 1600 boschs are the weird "middle of the road" type impedance. Thats my guess anyway. Too little to delete resistor pack and too much for the drivers to control properly.

Good luck and def keep all of us posted on how they perform for you.

This is directly off of Bosch website. If I remember reading correctly they posted the imp in its lowest test level. So I'm going to see how these do and if nothing else I can help someone else in the future.
