See thats where knowing the year really helps!!! You might be able to. Ive only messed with one zx and it was just a parts car. Good luck. And im not sure if there is a filter prepump or not, but if there isnt, its never a bad idea to add one.
We need to know what year car. Lets see if i can get this one. First replace the fuel filters. If that doesnt fix it Im going to say that your fuel pick up tube in your fuel take has rusted and has a hole in it. So that when your fuel is full it covers the hole no problem and just sucks fuel. but when its low it sucks air. If your FI this means low fuel pressure and your going to be injecting air instead of gas. To get to that you have to drop your fuel tank and take out the fuel sender. If its rusted you will be able to see it. I hope that helps
I believe the Z31zxt cas uses the same size wheel as the L28et. I know you can make the cas from the z31 work inside the l28et dizzy. I know this cause im running it. I also believe that it has different sized low res slots. Maybe this would work for you.
I think your backwards. Play with this calculator and you can see what im talking about. http://www.geocities.com/z_design_studio/ If your tires are already spinning, going to a 3.9 or so is going to make them spin more.
Why do you want a 4.11 rear end any way? Your car is turbo right? Its my understanding that you want a taller gearing on a turbo to put load on the motor longer so your not off boost all the time while shifting. My car was originally the 3.36 r180 i bought a z31 lsd diff with 3.7 and threw that in there and i hated driving with it. 1st gear was useless unless i was putting around. As soon as i hit boost the tires would spin. and i was constantly changing gears and it was just annoying. So i swapped out my 3.7 for a 3.54 R200 and kept the center section from the LSD. Im still searching for a 3.36 R200 though.
Also on the "wimpy" clutch pack you can get more disks and take out the spacers. Thus making it stronger.
Ive had a headgasket let go but still have good compression. It was just leaking enough to be able to pull in the coolant at low rpm high vacuum. Obviously its gotten worse before I changed it. But thats what it started out as. But it does sound like thats your problem.
I dont see how doing a v8 swap is going to be cheaper than bolting a l28et swap to get 300 hp. you can get 300hp out of a l28et really easy. I think i figured it out to be under 2k for everything. Obviously thats you doing all your own work.
My mulimeter from craftsman has both built in. IR and a probe. Both work great. only cost around 100 dollars. not sure of the temperature range though. Im not sure they have it any more though.
I didnt balance my xtd when i put it on. I havent had any problems. I am making to much power for it now though. I slip in boost at 20psi when im at the track now that i have wide tires. I need to get a new one but it served me well untill i started turning the boost up alot. For a stock or slightly modified turbo motor and pretty much any NA motor i say they work great. they do chatter from time to time though.
Im actually planning on doing the I5. i like fabrication but i dont think im ready to do that much. so ill take a hit of half a liter and still be .9l bigger than what i have right now and should be ok.
If they are only running 8psi and getting 350ish hp then id say it has alot more potential.
I Have decided that this will be the motor im going to throw in my z next or my next z. BUT I dont have the money right now. or a place to woke on it. But once i get settled in here in TN I will be tearing into it. Im thinking that a turbo would be the way to go also. Any one know what the colorado guys are getting hp wise to the wheels with turbos? Stock internals or not.
Wikipedia say it came in a 3.5l from 04-06 making 220hp 225 torque and in 07-08 it came with a 3.7l making 242hp and 242 torque. I wonder how much shorter it is.
Actually i read that the car she was looking at did have what she said. They changed cars or used a different engine bay picture later in post production.
seems like the incorrect com port. to me. at least thats what happens when i put the incorrect com port in. First of all do you have a MSII cpu in the megasquirt? if so you shouldnt have to reflash it to run fuel and spark. Also you do have the key on when you try loading the software right?
