I need a pair of rear stub axles (not the u-joint drive axle) and companion flanges from a 280z. If you have a set available please contact me. A friend of mine was going to help me do a 5 lug conversion on them and ruined the splines on mine when he clamped it to his lathe....long story. Going to stay 4 lug

I have been autocrossing in SM2 for a two years with my mildly built NA 2.8. I am getting a lot better, but now I believe that I am just underpowered compared to my competition. The main place I run is not a sanctioned SCCA track and no one was able to tell me what class going to the V8 would put me in.

Any progress this month? I just read through this thread and I am very interested in a set. I had read that people break u-joints and stub axles with there v8 cars, but I figured with my 1977 280Z L28 NA I was pretty safe. I was wrong. I took my car to a local drag strip this past Sunday and sheared 2 of the caps off of my axle u-joint (no play in joint prior to Sunday). I'm putting in brute force joints, but now I'm worried about the stub axles. I am in the middle of the chop cut portion of my carbed chevy V8 swap on my 71 240z using 300zxt axles and 280z axles. I went to a local machine shop to see if they would be able to convert to 5 lug for me. They said no problem since the axle was made of mild steel. I had it checked and it really was made of weak mild steel. I thought the MMS axles would be virtually unbreakable, but I see that some people have already broken them too. The car is primarily an autocross / occasional track car, but I enjoy going to a test and tune day at the drag strip for fun every now and then. I would like the comfort of having the strongest axles possible back there. When a stub axle breaks on an S30, does the wheel fall off too?

Thank you for your help and insight, that is exactly what I wanted to know. I too was walking through a local junk yard and saw the miata rack. Just so happens my car is already apart so I thought if I'm going to do it, now is the time. I will start looking for a Subaru rack. Thanks again.

Hello everyone, I'm not new to the site or Z cars, but I am new to V8 zcars. I'm just starting my build of a 350 T5 swap. I have searched for "power steering" "miata rack" "power steering rack" I have not found the answer to two questions. 1. What year Miata power steering rack would I use with my set up and the JTR kit? 2. Is the Subaru rack better, easier, cheaper, than running the miata rack? I have seen more info on people using the Subaru racks than I have Miata racks and I would like to know why. Any help would be great, or if my search was not good, can someone tell me what keywords will get me the information I need? Just a little of my history, if anyone cares. I rebuilt my 1977 280z to be a fun street car. I did some engine work (cam/shaved head/intake/throttle body, injectors) then some suspension and brake work (Tokico HP's and strut tower bars, toyota's). Then I found this thing called Autocross and I love it. Problem is, with the mods I did I was put in SM2 class and my ~200hp inline just couldn't catch the competition. So, if you can't beat em' goin em' I bought a 71 240z and I am in the middle of gutting it and putting in a roll cage, fuel cell, and of course the SBC 350 with a T-5 transmission. I want to run 275 series tires all the way around so I will be using POWER STEERING and I will use flares to make room for the tires. I can't afford coil overs right now so I'm going to go with the Tokico Illumina strut/spring package with plans to use heavier springs in the future. Unfortunely I will be running a 3.90 open differential for now since everyone wants the CLSD's and I think they are selling for just under 2 Billion dollars right now

I want to put the engine from my parts car 75 280Z in my project car 71 240Z. I am planning on using the factory SU Carbs. Anything I need to do to those carbs to compensate for the larger engine? This is my first experience with a carburated Z car. My other car is a 77 280Z.

I am looking to buy the Tokico Illumina shocks, but I don't want to go with the Tokico springs. I can't seem to find springs for the car other than Eibach's or Tokico's. I want a flat spring rate of 225lbs front and 250lbs rear. Does anyone know where I can buy these? My car is a 1970 240Z. I was considering coil overs, but I don't know enough about them to piece a kit together myself and I'm unwilling to pay the Arizona Zcar price of $1600 for the set.

I've searched and I can't believe I can't find this type of question anywhere, so I must be blind. Forgive me... I have decided to go with a carburated chevy 350 in my 71 240Z. I am not sure if I should install a 5-speed in the car or a 700R4. I do enjoy driving a manual car, BUT.. I am not very good at it. I slip the clutch and I bang the gear box pretty hard (horrible habit, but I can't seem to stop) I currently run my 77 280Z (built L28 5-Speed) in 6 to 8 autocross events per year and drive it 1-2 days a week to work. My goal was to enter more events with the 240 when it's done including a few trips to a road course. Does anyone think the 700R4 is a good idea for me? Has anyone ran a Z with a 700R4 in an autocross? If so, what was the verdict?

How is it different???

For relocating the rear differential and switching to a R200 - will all of the parts from a 280Z bolt right up or are the holes in different locations?

Is there anything different about installing a LSI/T56 in a series one car vs a series two car? The only difference I know of is the center console has to be replaced with a series 2 center console. Is there anything else?

I think you are all correct in saying that the JCI kit is the way to go. Thank you all for the input and pics.

Can anyone post pics of the JCI kit and tranny crossmember with mount? I've never seen what his kit looks like.

I wish I knew where I could get the JCI kit for $430. His website says the kit is $695!!! The JTR kit is about $275 and the adapter plates I mentioned are $50. That would be $370 I could put into the rest of the swap if it will work.

Has anyone been able to use the JTR small block conversion kit to install a LS1 into there Z? I know that the JTR kit is for older (pre ls1) engines, but I see that there are plates available on the internet to install a LS1 into a camaro, nova, etc... that originally came with an older style small block chevy. Has anyone used the combination of the JTR kit and the adapter plate with any success? I really don't want to pay the expense of the John's Cars Kit if I can avoid it.

Hello, I have a MS-1 v2.2 that I've owned for over 2 years and I am trying to get it to work. I had all of the wires connected last year except for the fuel injectors and the tach signal wires. I am using Megatune 2.25. I was able to see all of the sensors working. I neglected to follow the instructions on the tach wire and I accidentally connected the sheilding to the negative side of the coil. The coil got hot and the car would not run (i'm still using the factory ecu, I was just trying to check all of the new sensors). I disconnected the negative wire on the coil and the car ran again. What damage did I do to my MS-1? My MS-1 also has some kind of ignition control capabilities to it. I bought it used, but ininstalled and the previous owner did not remember what the program was called. I took the wiring harness cover off and saw that the #6 pin sheild wire was touching the bare wire of the #25 ignition wire. I put electrical tape between the two and closed the connector back up. The problem I have now is that I can not get Megatune to communicate with my MS-1. It would show all of my sensors working, but when I went to change any of the factors in the constant table, Megatune would loose the connection with my MS-1. I tried to uninstall Megatune and reinstall it on my laptop. I can't change anything under mscfg, or at least the "Activate" option never becomes available. Now I can not connect to my MS-! at all. As soon as I plug the cable in the Megatune turns off. If I connect and then open Megatune it tells me it expected "0x14" and the MS-1 is sending """ Can you please help me?
