Ok, so if I understand correctly, the first relay you mention is doing the job of relays 1-3 from the diagram pdf I linked to? (http://www.4moores.com/280z/files/ls1wiringNEW.pdf) And it would be very similar to the 7 fuse kit I have, with the exception that in that kit, 4 of the fuses are switched, and 3 are always on? What is the advantage of 1 or 3 relays doing the same thing? Is one way safer? Or maybe one way is easier to troubleshoot? As far as the Mazi Fuse you have for your powered components (fuel pump & fans), The 3 relay kit I have has a circuit breaker between the battery and the relays. Does this serve the same purpose as you Maxi Fuses, or do I need to have Battery -> Circuit Breaker -> Maxi Fuse -> Relays? Just to add to my info, I am running a T56 tranny. There are no powered components associated with this that need a relay, correct?

I'm on what feels like one of the final steps in my swap, wiring. I have very limited experience with wiring, I have tried to read up on anything I can find for this specific swap but I just end up confused about what advice applies to my specific scenario. Here's what I am starting with: Stock 1977 280Z, electrical seemed solid before I yanked the motor. Stock 2002 Firebird LS1 with stock harness and PCM. This harness came with the motor, but DOES NOT include the stock fuse block or relays. (This is the part that I think is confusing me the most.) Stock Camaro dual cooling fans. Upgraded fuel pump to Walbro pump. NOT running AC. What I've done so far: I sent out my LS1 harness and PCM to Wait for Me Performance to have the computer tuned and harness reworked. It has returned with clear labeling on the necessary wires. Based on a couple threads here, I purchased Painless Wiring 70107 - 7 Fuse kit (http://www.summitracing.com/parts/PRF-70107/) I also knew I would need specific relays for the fans so I purchased Painless Wiring 30107 - 3 Relay kit (http://www.summitracing.com/parts/PRF-30107/) Where I start to get confused: So the last thing I want to do is fry something. So that's what fuses and relays are for, correct? So I thought I had what I needed with the 7 fuse kit, but in the process of researching I found a couple places talking about 3 more relays and 5 fuses related to ignition. The clearest example I found was this diagram (http://www.4moores.com/280z/files/ls1wiringNEW.pdf). I notice the 7 fuse Painless kit, does have a relay on it. Does this kit somehow take care of the ignition relays/fuses? Next, Fuel. Do I need to add any wiring, relays, or fuses to rig up the fuel pump? Or can I just use the activation wire with the existing Datsun setup? Somewhat unrelated, One of the wires on the modified harness is labeled as clutch anticipate switch. I do have the pedal setup from the Firebird, but do I really need to rig this up in order to get the engine to startup? Thanks for any help

I am also looking for these bolts. I took one of my originals to Fastenal and they said they didn't stock (local or warehouse) the correct length with a button head. They told me they would try to find a source, but that was over a week ago. Finding a couple $3 bolts probably isn't really a priority for them... zGeezer, do you happen to have a link to the correct bolt on their website?

I understand how to find the length. I just want to see how people are routing it. When you do both PS and AC delete you're left with a combination of pulleys that doesn't work. I've seen that you need to add a ribbed pulley but I was just hoping to see exactly where it goes...

Thanks for the length Sunny Z. I'd still like to see the completed belt routing. The link to the thread above includes AC or some other accessory, and moore's pic only shows the single pulley.

smoorenc, Do you have a pic of you complete belt routing? BTW, your build website is an amazing source of info on this project. Looks like you're getting real close. Thanks so much

Ok awesome. Also I realized I didn't include the filter before the pump in the diagram. I'll have to add that tonight along with the fittings.

Thanks again all I think I'm almost there. I made a quick diagram to see if I'm understanding h4's setup correctly. A few questions: 1. The pic/description on summit racing for the pump is confusing me. (http://www.summitracing.com/parts/VPN-GSL392/) It clearly says threaded 10mm x 1.0 for both inlet and outlet, but in the pic I feel like I can clearly see a nipple end. What connectors exactly do I need to finalize my diagram? 2. Is it fine to use normal rubber fuel injection hose + clamp to connect to a hardline that does not have a nipple? For instance in the case h4 mentioned where his new hardline ends in the bay, I'm assuming this is just a clean cut smooth end. Or in the case of the connector coming out of the corvette regulator to the rail... 3. What would be the easiest/correct way to cap/eliminate the vent on the tank? Thanks again!

Doesn't the camaro tank require cutting out the spare tire well? I'd prefer to leave that in tact, if the stock tank will work just fine.

Thanks everyone for the more detailed info. h4, your setup looks especially easy and clean, and thanks for the specific part numbers and such. I think this method may also solve my tranny mount interference issue as well. Do you have any pics of the components in the rear? With your setup did you eliminate the other stock component next to the stock fuel pump, some diagrams have this labeled fuel dampener? Does flipping the stock fuel rail still allow the use of stock (or similar) corvette rail/injector covers? The fuel filter you mentioned asking Napa for, does that go between the tank and the pump? Along with the stock brake, fuel feed, and fuel return lines, there is a 4th line running to above the fuel tank. I am assuming this is some sort of vent/vacuum line? What should be done with this? Can it be eliminated?

Hey All, I hate to be the guy that seems like he's not using the forum search, but I really have tried and just can't piece together a complete, easy to follow solution for someone like me with very little experience. I am starting with a running, stock '77 280z (EFI) and swapping in an LS-1 from a stock '02 firebird, stock fuel rail. I should state that I am not looking to take this car to the track, I would like it to be a reliable daily summer car. So my priorities for the setup lean more towards ease of diagnosis and keeping the engine bay looking clean, rather than ultimate performance. I am looking for a complete list of parts I need to get, and where they go, to finalize the fuel setup. I have tried to sift through as many threads as I can, but it seems like one portion or another is always generalized or assumed. This is my first time, so I need some hand-holding Here's is where I'm at: I have already removed the L28, and mounted the LS-1, following instructions provided with the JCI mount kit. If I understand correctly, this means I currently have 2 hard lines coming from the rear of the car. The first is currently going from the tank, through original fuel pump, fuel damper, then to the engine bay. The second is the return and it goes directly from the bay to the tank. Here's the general setup I have been able to piece together from different threads: Keep the stock 280z fuel tank, as it is already setup for fuel injection. Add a fuel filter between the tank and new pump, to protect the pump. Replace the stock fuel pump with a higher flow pump. Keep the stock hardline going from the pump to the bay. Run this line to a fuel pressure regulator, preferably with a guage. The regulator will have 3 line connected to it: ⃠The line coming from the pump. ⃠The other (return) hardline ⃠A line going directly to the stock LS-1 fuel rail Another fuel filter somewhere? So assuming that setup is somewhat accurate, here are the questions I have in order to make it more specific and more of a step-by-step process: A. What fuel filter should I use for step #2? B. What new parts specifically (lines, fittings, etc) do I need to add this fuel filter? C. Is this filter something that needs to be mounted? If so, how? D. Which new pump should I use? I have seen 2 main options: ⃠Walbro GSL392 255 lph (http://www.summitracing.com/parts/VPN-GSL392/) Would I need any extra parts for mounting? ⃠He doesn't give any part specifics, but the high flow pump provided by JCI. E. What fuel pressure regulator specifically should I use? People seem to mention Aeromotive a lot but there are so many options. F. What new parts specifically (lines, fittings, etc) do I need to complete the 3 connections the pressure regulator will involve. G. Is there any generally accepted place/way to mount this regulator? Is there an existing bracket or something I can purchase? H. Do I need a second filter? If so where, specifically what part, and where does it go? I. Do I leave the stock fuel damper in the setup? J. The JCI instructions mention re-routing the lines to go straight up the firewall. How is this accomplished? Can the hard lines be bent in some way? K. Some have mentioned flipping the LS-1 fuel rail. Is this a good idea and what does it accomplish? This is a side note, but it may have some impact on the fuel setup. After reading around it seemed everyone had a better opinion of the transmission mount from JTR rather than JCI, so I went with the JTR mount. However it seems it will interfere with the stock placement of the fuel/brake lines. (pics) What is the recommended way to remedy this? Thanks in advance to anyone willing to help. I know it takes extra effort to provide specific info, and it is much appreciated.

Thanks guys, yeah that's what I was after, what parts were being used in the front. I'm also still curious what it looks like head on with the round fogs in that location.

Does anyone have anymore pics of the front of this car? Or others with similar treatment in the front?
