Bandit50. I guarantee that he has thought this through. Derek has the skills and most importantly the TOOLS to do this correctly. Yes a fuel rail would be easier and maybe even perform better but thats not what Derek is going for. Remember here is his criteria for this project.
1. Look cool.
2. Look really cool
3. Actually run.
Its not only the bumpers but more the bumper shocks. Those weigh alot more than the bumpers themselves. There is also some extra bracing inside of the doors that adds some weight also.
On the part of it where your car goes lean. I had a problem like that and it turned out to be really dirty battery terminals. I was amazed at how much clean terminals made my car run better. Im on a mac so i cant look at your datelog. But what does your battery voltage look like? is it all over the place? Ive been fighting some resetting issues for probably about a 4-5 months now. Ive finally gotten it to where the car is drivable but im this close to ordering another MS probably the 3.57 board because its supposed to have different ground plans for less noise. But there is still a few things i need to try. Go read this thread on this other forum. I did the part with the R/C filter on the backside of the board and it really stablized my voltage. I was pretty impressed. Im still getting a voltage spike every now and then but its livable. I have made the seperate ground board for it on the back but i dont have any extra FET mounting kits laying around so that i can mount it. I just need to order them.

Looking great derek. Also you will be able to get rid of that block heater you have on your car once you go to full megasquirt! lol It doesn't need to be warm to run smoothly! And im sure it will work also. You think things through way to well for it not to. NOW HURRY UP!!!! you need to have this at DNI this year
I was actually talking about the Injector clips for the electrical. Just make sure you have enough room to get them off and on before they hit the fuel line.
You have to cut some wires. to do it. But Its knowing wich ones you can and can not cut which is key. And It looks like you have a turbo engine. Are you trying to run a stock NA efi on a turbo motor?? cause if you are it isnt going to run that well and you might damage something.
Ya the guy gave up on trying to get it started. I bought it as a non runner with the gas tank out. Cleaned it out a little bit and got fresh fuel to the injectors and it fired right up lol. He was going to scrap it and thats what the scrap yard told him they would give for it. lol
All turbo 280zx's came with a R200 3.54 rear end and with the cv's If you have an early 260 or 240 you can even use the companion flanges. If you have a late 260 or 280 you will have to use Modern Motorsports cv adaptors. so to recap. All 280zxt's have a 3.54 R200 in them.
Oh buy the way i got my whole turbo 280zxt for 200 bucks!!!!!! lol but i got lucky.
I think the general consensus is that they dont hold up well to a turbo engine. But for your NA build im sure pretty much anything should be strong enough. Probably even a stock clutch could hold the power.
You can also use a flywheel off of a pathfinder and a few other nissan trucks. Its a 240mm and it doesnt have the "cooling ring". It only has 6 bolts for the PP though. Which wouldnt be a big deal if your redrilling it. I have one in my car at the moment. And thanks for the info on putting a bigger clutch on also.
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.
