e-85 is good but I'm just going pump/ Methenol injection. Get's the benefit of cooling/high octain with the methenal and the easy access pump gas for driving around. At the track I'll put in some high test for the 1k+ rwhp runs.

I could see a good benefit running it in a high compression NA car. Definitely cheaper than race fuel - for now.

Don't know where you got the injectors but the 120/160 one's I'm looking at are high impedence.

yea like don said in our area i would absolutly go pump gas on methanol/water injection.......e85 isn't widely avilable enough to run on it for a street car not to mention as i said a few posts ago the consistancy must be mainained for the tune to maintain its consistancy........just not pratical in our area for a street car........they do make high lb/hr high z injectors however im not a fan the open/cls rate on the valves in the injector are not that fast compared to a low z injector with the peak and hold 4A circuitry control.....the low z injector will be easier to tune for the street and will be more managable due to the lower minimum pluse time and more consistant open and closing times from injector to injector........if you do want to run the low z injectors accleeronics makes a module called the versafuler which will allow ur stock ls1 pcm to control the low z injectors.....think its only in the 250$ range.......may want to look into it, it will be well worth your $$ at $250

good luck with your build

Thank you i'm still on the fence its a tough decision. The e85 is about 15mins from my house at a station but getting 4mpg might not be worth it!!!! Also Don I got the injectors from a guy on lstech

Where did you get high impedence 120's?? What did they cost? I really dont want to buy a converter box for the injectors but if i have to i will....

Little more progress made waiting for parts to come in to put it all back together..... Bought a TU2 236 236 .587 .587 112.5 Cam from Speed Inc..Pushrods, Lunati Double Spring kit, LS9 Gaskets, FAST Fuel Rails, SLP Double Timing Chain, SLP Oil Pump, ARP Head Bolts and Rod bolts. Then Going in to start it up and mock the piping.....

thing looks AWESOME!!! Way Better then wen you got it!!! you get the conn. rods resized after the bolts?

[Slowhawk]

Head bolts? I hope you mean head studs.

[ILuvPizzaTimes10]

how much of a benifit are the syuds over bolts for a turbo/FI application. and worth it for an N/A Setup?

Thanks man and yup I did I read a million threads about whether to resize or not since they are cracked but when it came down to it...40 bucks to resize them might as well eventhough personally I think if you do one at a time your fine but like i ssaid 40 dollars and now I dont have to worry

vague.......more a matter of predicted cylinder pressures than that.....with a gapless ringset and 14.25:1 im running studs without question with a cometic....a composite gasket and bolts didn't last long at all on mine four years ago....
