Yeah.... 2000cc is all they have in my range.... I have 1200cc now and don't want to go back to 1000cc
I was told that the ID is a great injector..... Plus i am told it's the best for the high impedance I am looking for. I am not sure what the price is ... But my guess is the ID cost more than the HKS 1000cc that I use to have.
E85 is not ony list.... We don't have it here in the south.

Like that would stop you at this point

I'm in the same boat. It looks like there are stations to the north of me in St. Lucie county and to the south of me in Broward and Dade counties, but nothing here in Palm Beach county...
Although 1000cc injectors are adequate for my hp goal, I'm tempted to get the 2000cc injectors so that I can move to E85 if it ever becomes available in my area. My major concern is idle/low rpm (under 2k rpm) characteristics of the 2000cc injectors using the F-CON for tuning on gas. Please let me know how well Shariff is able to dial in the idle/low rpm characteristics when you move to these. Unfortunately, I still seem to have time as I wait for Japtrix to get through their backlog of cars that got in there before my motor arrived (nearly 2 months ago).

I have no choice at this point Chris....This car has me trapped into installing the TC....

broward has a few E85 stations... closest one to me was 1/4 mile away, now that i moved its about a 15 minute drive... would of ben a hassle but i opted for the Proefi so now i can use whatevers around without stressing finding a E85 station. i cant remember the site, but Boca area was slated to start popping up E85 stations too..

Mike,
Are you looking for high impedence injectors so the TC can control them.
I know some of the 1200's (I think its the RC's) don't flow 1200cc (or even close, actually like 1080cc)....the new precision 1200's flow 1290cc (as tested by folks on here too!!!)
Then there are the 1600's, and then up to the 2000's and 2400's.
I know the supra boys are saying that the precision 1200's have a much better spray pattern than the rc 1600's.
But if you need the high impedence, yea you are much more limited in options. Maybe check to see what the evo folks are doin (I know some of them stay with hi impedence for ecu controller problems).
Or, dare I say, ever thought about a twin injector setup (common rail, 2 injectors per cylinder)? Granted that will be quite a bit of customizing, but you probably have enough room with the cosworth mani on there.

Your still running the F-Con right? Just make sure it can handle that large of an injector. Getting into a size of injector that won't want to idle well or drive well with some ECU's.

Thanks for that info.... I will ask about that..... Won't be happy if I have to change the F-con

Injector Dynamics ID2000 injectors look good down to 0.5 ms injector pulse width(corrected for dead time) according to their published data. So you'd need to keep your idle above whatever that correlates with. Doesn't sound too bad... but of course no real world data on our platform that I have been able to find. Guinea pig time!

The rumor was the IP shop car was going to 2000cc Seimens or ID's almost 6 -8 months ago. Not sure if that happened yet.
I dont know if its because we never changed the latency and injector size from the HKS1000s, but my idle was a 12.5AFR with like .1ms IPW. Couldnt go any lower to lean it out any.
But those ID's are definitely much nicer injectors.

I am putting the ID 2000's )actually flow 2200cc) in my GT-R next week. For all accounts, they idle and start just like OEM...at least with the OEM GT-R use. I'd like to try them on the VQ35 using a Haltech or FCON, but the feedback on these large injectors has been uniformly positive.
and after seeing retail on the ID2000s, would love a deal to try them

It would probably be cheaper to replace the Fcon/racelogic setup with a ECU that has built in traction control and uses low impedence injectors (more options and smaller are cheaper)........
Those big ID's are really expensive.....and other cars/platforms have made your power and more with 1600's.......
Just thinking out loud.

Is the resolution of the injector timing control better on the Haltech compared to the F-CON? If it is not, I'm not sure how changing to a Haltech will make a much of difference as far as idle/low rpm characteristics go.
