Ok I give up and I'm having a "high heat" stainless steel braided hose built.

OK shes running again. Everything looks great so far.

The exhaust system is working out great!!! Very quiet and stealthy.

I'm still going to build a few heat shields(upper radiator hose and between the head and manifold on the dist. side)

Nope, the stock ignition on these engines are amazing. There are several
500whp 1.6L SOHC Honda's using stock ignitions.

EDIT:

Ok I'm thinking about going with a different trans oil.(Ams oil etc)

I have been using Honda's Manual Transmission Fluid (MTF)

Has anyone on here seen any improvements of FE over Hondas MTF???

Thanks for that link. I wish i could see your setup in person! It is exactly waht I would hope to achieve if I had the money, and knolwedge t

Thanks!!!

Its taken awhile to build it and more money then I wanted to spend but so far has been worth it. The new turbo setup has been giving me some problems but I think I got it figured out now.

My biggest concern now is when I start the dyno testing and hoping that the transmission gears don't go flat on me and hurt the FE side of the setup.

Aren't you in Portland Oregon? If so I will be going through that way when I do my next long trip FE test. My goal is to see if I can make it to San Francisco on a tank of gas.

Yeah! I'm in Portland. Definitely let me know when you come through here. I can drive along side you, so you won't have to use extra gas Or you could not count the extra gas to meet me somewhere...
Do you know;
I'm thinking about heating the fuel line to help combustion. Some people said it didn't work, but they didn't have standalone EMS. I can, of course lean it, so the heated fuel would make a bigger difference. Also, theoretically, Acetone loosens the bond of Gas molecules for better atomization. I do see a FE gain when I use it, but haven't used it with running lean yet. I'm also going to put in an MSD6A, even though I've read it won't do much. I already have it, and it won't hurt.

I will definitely let you know when I will be heading your way!

IMHO I think heating the fuel does contribute to better FE. I did some testing last Fall and it look like I saw some gains around 4% in FE. I'm going to make a better system this year. The one I was running last year was kinda ghetto but it worked.

I haven't tried the Acetone deal yet.
