Ive been looking at these Flex Fuel Kits they make now. How well do they work?

Don't bother with them, you'd be better off with 30% oversized injectors and an adjustable FPR so you can adjust the fuel pressure up or down to run gas or e85 and check your afr's with a wideband like the aem uego

hmmm, seems low, but the again I come from subies so idk what the ka24de's run stock. A stock wrx runs like 42 degrees advanced at idle from the factory so It's quite a difference from what nissan's run I figure.like I said, swap out the manifolds, see if there is any difference.

you really dont need one in a 240sx. If you just wanting to run e85 in a stock ka24de i've seen people drop in sr 370's with no tuning and run e85 with no problems. You just need to change the tune if you want to run stock injectors. It can be done with the stocker's but, idc is probably 100% if you run stock fuel pressure. | Quote, originally posted by sorrowfulkiller » | hmmm, seems low, but the again I come from subies so idk what the ka24de's run stock.

I found today that it wasn't the manifold when i pulled the old one off today. The turbo didn't spin very freely so i'm thinking that the restriction from the turbo is what caused the high heat. Since i already bought another manifold i'm going to swap anyways. I have a lot of work ahead of me to switch to this new manifold (DP, hot pipe, intake pipe, re-locate coil). I hope to have her back together in a month......going to rebuild the turbo also.....if its ok.

If you can, try taking apart the chra assembly, from there you will be able to find out if you need to change bearings and seals. Get turbo rebuild kit, rebuild turbo, put it all back together. Depending on what kind of turbo you have you're going to either need a very large snap ring pliers or just normal sockets to take off v-band clamps and bolts holding the compressor housing onto the chra housing. In the turbo's I've taken apart, the compressor wheel stud was reverse threaded AKA lefty tighty righty loosy the turbo side should be normal style threaded. I would ask a company that rebuilds turbos what sort of torque you should put on the compressor bolt when you rebuild so you don't have this problem again. Another thing, if your turbo is only oil cooled plan on buying a turbo timer (ebay knockoffs work just fine) I would generally say to let it idle for atleast a minute even if you haven't been boosting. My guess is that your oil is getting coked up in the bearings

+1I have everything apart except the chra....both fans look great. Time to get back on topic......i'm sure WD is about ready to lay the smack down...."Do you smell what the WD is cookin" E85 clean burning FTW.

How much HP can Dual Walbros support on e85? Im looking at upgrading to e85 for my T67 SR20. I need something 750hp Capable.

 | this is one more reason I love e85, clean burning (releases 1/8 of the greenhouse gases that gasoline does)

I'm not sure off the top of my head how much two walbro's can flow hp wise with e85, but all you really should need to know is how much fuel your target horsepower rating would need, multiply your fuel flow for that hp rating by 1.30 for 30% more flow because of e85 and figure out how many liters per hour that is.1 Walbro can flow up to 255 lph, so 2 would be 510 lph. Also for injectors if your using a boost referencing rising rate fuel pressure regulator you should take that into account before you buy injectors. the rc engineering website should have all the info you need under their "injector sizing" area

I believe dual walbro's can hold around 700whp, pushing it...you might want to look into an external fuel pump

I know of two ka's that are making 700+whp and one rb26det making 800whp on e85 that are running dual walbro's They aren't having fuel pressure problems as of yet as far as i know. If you already have one walbro i would look into having a bosch 044 as a inline and the walbro feed it.

Doesnt the Walbro pump just feed the inline pump? I didnt think it actually added into the flow rate.

You very well could, possibly without any fuel controller too- you'd just have to check afr's via wideband-However- it'd be a waste of corn fuel on a stockish n/a setup, and def not enough fuel for any turbo app

im asking because there is a gas station near me. so cheaper gas which lets me run alot more timing and keep my engine running cooler. i have all bolt-ons and the cam swap set-up.

Don't switch to E85 because you think it will save you money. On a completely stock motor, it won't. The decrease in fuel economy won't pay for the decrease in price. Where E85 shines in a situation where you have exceeded the capabilities of pump gas. What I mean by this is that if you have to run more fuel &/ less timing to keep the motor from detonation due to the octane rating of your fuel, THEN E85 is a great option compared to race gas. This is exactly the reason why flex fuel vehicles are basically a bad idea. They'll never get the fuel economy that the same sized gasoline engine will. BUT if you were to design a motor to run on purely E85, not only would you be able to make it smaller and lighter with out sacrificing power, but it would get at least the same, if not BETTER fuel economy than the gasoline engine it replaced. And to really mess with your head, imagine coupling that idea with hybrid technology. You could literally have a 500cc engine with a 150hp/L output that gets gas mileage better than gasoline and weighs CONSIDERABLY less.

Throw a set of sohc pistons in there for a hi-comp build and then it might be worth running e85 so you dont have to pull timing.

well i already rebuilt my motor with new rings and bearings so dont wanna pull it apart again lol. just wanted to try it since az is so damn hot, i wanted my motor to run cooler during those track days longer.
