Install kit = $75
600cc's = $500
Uprev = $500
Tune= $500

$1650 for 10 HP?

Not to mention you will be glued to certain stations and you can never take a decent road trip unless E85 is everywhere in the area which in most cases isn't.

The only way I can see this making sense is if you are running without cats and the smell is bothering you. But it had better bother the **** out of you for that cost.

Well I already have the software so it would just be a retune cost and parts. I do run test pipes, but I dont notice the smell at all nor do I take my car on long road trips lol. Are the stock injectors maxed that close to 100% at this point to need the 600cc? Not looking to cut corners just curious.
Could be something I look into now.

Well if you have already been tuned and your tuner is cool he can check your map and see what duty cycle they are at. But I highly doubt they will be good to run E85 on. Besides, you wouldn't ever want to take your injectors to max. 80% is the max you should ever go.

If you ever tune again ask for all that information. Duty cycle, timing adv., afr's, etc....

lol you dont own a subi do you? those guys run 100-115% IDC all the time. at least with subi the IDC isnt each injector by itself. its a % of all and i cant remember how to put it. i used to know everything with them cars but its been like 2 years really talking about them so i forget. their IDC was a good 15-20% off though. if the Z is anything like it then you might be ok for high 90's and still have plenty of head room.

the seals do worry me though. if they arent Vitron? then E85 will eat it. older cars get "the black sludge" where E eats everything!! i dont think you can tell this on a 370 though since we dont have a return fuel system. on older cars or return system cars its really easy to see as your sock will be solid black with tar, or it wont.

im getting a tune soon with the ported everything then again later with E and injectors and possibly fuel pump. like everything on a Z just sit back and wait a while haha.

PS...how hard is it to pull the lower manifold? can i leave the fuel rails attached to the car or do i have to pull it out of the way and relieve the pressure in the lines?

You will not want to run 1000cc's on stock pump without boost. You will atomize like crap and will have more like a jet stream then a mist and you probably wont be able to hold an idle.

You will have to pull the rails and you will have to relieve the pressure. There is a hardline that connects the feedline to the rails that needs to be taken off. It is super easy to access though. Its right in front.

Well I have always seen that anything over 80 is just a gamble. Yes you can run them at 100%. But that is unsafe and if your pump doesn't hold a perfect voltage, which it wont, then you are just waiting for trouble. My tuner wont let me take mine over 80 and he knows his shiz.

I have to disagree. At idle any pump is running normal voltage. ID 1000's are the best at holding a perfect flow no matter the rpm. They run better than OEM on almost any car. I'm not worried to even run 2000's from them. I've seen it a million times. Even on the highway at 80mph under normal driving no pump is running more than another, it's not needed since you're just cruzing.

Anything on this car? Because I can't name one subi that doesn't run high 90's and half run 100% easy as most do on a stage 2 tune.

Are your injectors at 80% at idle? I didnt say anything about idle voltage.

Anything on this car? Yeah, or theres no way I would run E85 and 1000s.

Run yours at 100% on a boosted application for a few months and report back please.

ok once again im asking if youre talking about this car or a subi? youre going back and forth or not at all. im being very clear which cars im talking about. i havent tuned my z yet so i dont know the IDC or how nissan monitors the IDC. subis monitor very crudely which is why they all run 90% to +100% IDC and yes they are boosted without issue.

lol why not? 1000's plenty if head room and 2000's run fine without issue on multiple peoples cars i know.

and you didnt have to say anything about idle voltage per say. you clearly said "You will atomize like crap and will have more like a jet stream then a mist and you probably wont be able to hold an idle." that means youre saying the OEM pump at idle wont be flowing the correct voltage and will run like crap. i say youre wrong because at idle a stock pump and an aftermarket pump will be the same, so explain how it will run bad? the tune will pull back the fuel within the injectors and any car with ID injectors whether 600's 1000's 2000's etc with any pump will idle fine as ive seen it happen before.
