go with something that let you tune by throttle vs rpm not a MAP or MAF.
good luck on your build.

Can any one recommend me a 14-15 gallon fuel "cell" that is e85 safe.
And has anyone on the forums actually made a full switch to e85, converting all lines rubber and metal to stainless?

im running E85, im just using the hard factory lines for return. My feed lines are the braided ones from ptuning.. just use your oem tank i dont think there will a problem

do you happen to know what those lines are rated at? Im excited to make the switch, there is only one station by me though :? I hope a few more pop up.

rating as in pressure? im sure they will hold plenty even rubber fuel hoses hold over 100 psi.. me too only one station here within 500 miles lol so i have a 5 gallon tank if i have to drive far

flex fuel would be nice, so far its only proefi that carries it for our cars (there's one for sale here right now) and hydra still hasnt released that feature they are working on..

Nice to see someone else going down the n/a road. cCurrently my project is on hold, but that being said if its a track car youre looking for it sounds like youve got the plan down well. Honestly if youre getting the stroker kit involved and are willing to go high comp 12.5+:1 i dont see any reason that 230-240whp wouldnt be possible. the only real item of concern is that youre looking at a very long stroke and a very high cr, match that with the inherently narrow valve angle and subsequently uneven flow in these f series engines and i fear you may run into detonation issues on 93. That being said if you can get e85 then forget all i said and tune it like crazy, as e85 seems to love timing. And on the ems note, either a haltech or a custom motec setup would probably be best (ditch the stock ecu as piggeybacking, no matter how good just ends up being a pain, and its not like you need a/c in a track car). Very interested, keep us updated.

Im planning on going the e85 route, but I might need a way to switch maps or something because e85 wont always be available to me, and when there's no summer blend at the local station I might have to have a different map for that as well.

Trying to get this all planned out before I go blindly spending and dont get what im looking for again..

or you could bring a beater laptop all the time with the car to switch maps like what im doing lol.. i didnt notice any change in afrs and just a lil change in fuel trims from winter to summer so I dont think there is a change in ethanol % here in our area.. but 10-15% less eth content should just be compensated by closed loop and at WOT maybe just a slight difference

I second the beater laptop also. Plus you can pull a F&F and have it scream warning messages about your manifold pressure too. JKJKJK. Honestly the laptop may be the best idea. Although i thought with the Haltech 6x you had the ability to switch maps? Ill need to research some more.

Is thermal coating on pistons worth the money/result?

What about boring out the engine and get around 2.6L out of it instead of 2.4L?

Well the bc stroker kit actually will have a end displacment of 2.6 when it's all said and done it's going to be a torque monster that's for sure

boring is only possible to an extent, and requires re-sleeving in these motors, even then by overboring to a 91mm bore (2.5mm over, and generally as big as youd want to go) youre only gonna get a 2.5L. you have to stroke these alu block engines to get more displacement for the most part.

mileoutrage, im gonna run a few plots in engineanalyzer and see what type of curves it comes up with. ive got a fairly accurate model of the 2AZ set up in there right now and i want to see for myself how much stroking and boring would add to this engine. with other proper supporting mods too

TYLER

hmm, so its thinking around 235 whp@7250 with around 210lb/ft @ 5000 with full supporting mods on 93oct with some fair timing. Somethings throwing off the race fuel calcs at the moment. on a plus note you have 200+ lb/ft on tap from 2000 rpm-7000 rpm. That would be real handy getting out of tight corners, especially against a lot of turbo cars that dont make that much till 4k rpm. This would be on cams similar to the bc stg 3 n/a. If you went with some real monster cams and were ok with 9k rpm 260whp appears possible but with a lower overall torque curve. hmmm, tempting, but i need to focus on my new project. for now.

TYLER

Man I hope I can reach these numbers on my build, I really want a very useable powerband because this set up will be for TA sessions and weekend use.

wat injectors would you need if for a na bulid with e85 and a return system help out or not

any one no of where u can get pistons that are higher then 11.0:1

700cc and CP will let you pick the static compression ratio, same with the BC stroker kit

Yup around 750cc at bfp on E85, CP, and JE will let you choose for the most part, same with the bc kit, just make sure they enlarge the valve reliefs for the higher C/R and if you have oversized valves.

mileoutrage - honestly i could see those numbers occuring in your build, afterall, 100hp/liter is common in high performance factory engines, so in a race build 120hp/l or so should be attainable. i want to hear a 2az at 9000rpm on itbs...
