E-85 on a stock 370z?

JeffP-Z

I spent some time over at SZR Pro today here in Houston talking with Dane and Brad about build plans and some of the conversations here. The did acknowledge that some people have had some oil return issues on the AAM twin turbo kit and believe they have worked out the issues. Dane is building a fresh motor with the aam stage 2 kit on it and explained some of the known issues being the left side turbo oil line comes default with a straight an fitting and being so close to the fender well, it often gets pinched or kinked. Additionally have the return lines enter the oil pan (wide Greddy I think) vertically instead of from the side helps alleviate pooling in the lines and lateral flow issues. Sound like they may have that kit dialed in well and given the lower price tag (compared to FI) it might still be a good option.

On the build details, here is the road I will begin traveling down:

1700cc injectors $1500
Specialty Z Flex Fuel Kit
AAM Fuel Rail Kit 1329.99
FI Fuel Return System 1045.00
FI or AAM Twin Turbo Kit
Catch can kit
ATI Super Damper
Walbro Dual Pumps
Greddy Profec Boost Controller

P.S. Whjaxn17 - I love how you just can't resist trolling and throwing in your useless 2cent comments. I already admitted I was new, I already admitted I was not knowledgable on ECU/Fuel Injected setups, I already admitted I screwed up buy jumping the gun, and I learned a lot from this experience. Unfortunately all I learned from you is that you don't have valuable input and I should ignore anything you say. Start acting mature and prove me wrong.

Don't get any fuel system parts from AAM. Their fuel system kits are having issues. There is a thread or 2 on the problems.

On the oiling issues on the AAM turbo kits. Some have installed an oil scavenging pump on the return line.

Any recommendations on rails/gauge then?

Phunk at CJM. He has complete fuel systems.

Don't get so butthurt over some of the comments. We all screw with and make fun of each other. The people you're calling trolls are extremely knowledgeable people and can be great help with your build process. Just go with the flow. Everyone gets picked on, it's nothing personal.

With that being said, CJM S1.SE return fuel system is probably the best on the market. It comes with billet fuel rails and you can order a fuel pressure gauge with the kit.

And what kind of power are you looking for, 1700cc injectors may be overkill. 1300cc may be a better choice.

Yea. They might be overkill but basically 600 until I decided to rebuild the motor and then 800-900 in the end. I had a buddy doing about 1050whp and I dont know if I will ever go that high. I guess my thought process is if I am spending 1300...why not spend 1500 and never have that as a limiting factor. Is there a downside other than the price for getting the 1700s?

Yeap, 1700cc are good for a mostly E85 car. Run them on 93 oct. and you will get some funky idling, etc. This is from personal experience. 1300cc is all most folks need unless they are wanting to push the HP level. If that is the case, it can get expensive quick. Re-do's suck and are quite costly.

How much money do you think they are making on selling you the AAM kit and install? They think they've figured it out, but they're still in the middle of that build? Is that what I just read? So how do you know they fixed it? Do you really want to be a guinea pig to find out whether they actually fixed it or not?
I recommend you listen to Rusty and tell them to cram that AAM kit in some other chump's vehicle


You certainly have an interesting definition of "useless". He literally gave you a perfectly understandable response that you completely ignored. So what kind of response do you think you deserve?

Probably not as polite of a response as the PM I just sent you

Just a couple notes here. First, I'd highly recommend that when forum veterans slag the AAM kit, you listen. AAM has a very bad track record here as far as quality and customer support, for a reason. I realize they are marginally cheaper - How much pain is that worth to you, in the long run? I should add that their kits do make good power once everything is set up. Just figure out your pain threshold getting to that point.
Second, your build list here is definitely showing an improved thought process. You're listing the right kind of components and you're doing it before building anything.
Third, if you have questions about injector size, talking with a knowledgeable tuner with a lot of build experience, such as Sebastian at Specialty Z, would be a very good idea.
Lastly, try to figure out your power goals in advance. That'll make your build decisions a lot more obvious. 500 whp? You won't need E85; you don't need a built block; you can run smaller injectors; you can keep relatively small turbos. 750 whp? Whole 'nother game. Now you're talking built block for longevity, with only a handful of shops providing proven motors at that power level for any kind of duration, likely E85, upgraded turbos, etc.

Built block in the neighborhood of 15 to 20 grand to do it right.

Jeff, old boy. I got a question. What ever gave you the idea of running corn on a stock Z?

Stupidity in reality....but I was looking to take advantage of the marginal HP gain I would have expected. But as I may have already said, I leaped before I looked...bad plan! I was getting beat out there by guys with much better builds and thought it was a quick easy way to make more HP. I am too impulsive sometimes and it got the better of me this time. Add this to experience category and keep on keeping on. Fortunately I am a persistent SOB and wont quit till I get this right. I am on a mission to learn as much as I can now and will try to STFU and read more and understand better.

It's only worth ~10whp NA. I see you've mentioned going TT since I answered and it's worth way more power there, or at least allows for more w/ a comparable safety margin. I'm not sure what you should expect to pick up boosted on E85 over 93 or 91, but Spooler or Hotrodz might could share some experience.
