    WTB 5 Speed TPS for 240SX 60mm Throttle Body

    in Parts Wanted

    Posted

    Actually bought and modified it (spacer, cable linkage, etc) about five years ago. It was from a 240sx. Did not realize it was from an automatic. Had the head rebuilt and then the car was laid up.

     

    Just gave it to one of my sons and his mechanic got the car started. Sounded great but the mechanic said the TPS was wrong. I do have the original 280zxt TPS but the bolt up is different.

    1982 280ZXT - rear end seal for gearbox

    in S130 Series - 280ZX

    Posted

    Courtesy Nissan in Texas tells me Nissan no longer stocks the rear end seal for the 1982 280Zx turbo car 5-speed gearbox - which I think is a Borg & Warner?

     

    Anyone has any idea where I can get a replacement?

     

     

    Also, Nissan wants an arm and a leg for the little rubber? connection between the oil-pan and the turbo drain-pipe. Is there any other less expensive replacement i can use?

    1982 280ZXT - replacing engine gaskets

    in S130 Series - 280ZX

    Posted

    I have removed the engine from my 1982 280ZXT to replace the head. I will also replace the timing setup.

     

    This is the 1st time I am doing this type of repairs, and I am confused by the hugh variety of different sealants at the autoparts store.

     

     

    I am looking for recommendations on which sealant I should use with each of the different gasket involved, including the oil-pan gasket.

     

    Any instructions on how to use the gaskets, e.g. spread thick, or thin film only, etc, would also be welcome.

    Turbo upgrade for 1982 280ZX

    I second Brad's recommendation.

     

    T04E-50 trim is about the best match for a L28.

     

    Use the stock turbine since you are planning to use the stock cam. The power band of the stock turbine matches the power band of the stock cam very well. However, I would recommend you use a NA cam which good for another 400 or 500 rpms of useable power over the turbo cam.

     

    If you plan to change the cam to something bigger, then open up the turbine to match, as bigger cams with more overlap don't do well with small restrictive early spooling turbines.

     

    More important to use a bigger down pipe with a small restrictive turbine (stock). So, use the 3 inch down pipe.

     

    FYI, you are going to need about 18 psi of boost to make 300 hp at the wheels with a stock NA cam and head.

     

     

    Already had a 1981 head rebuilt - just a simple build.

     

    I have decided to go with the T04E-50 trim, standard turbine. I want quick spool-up (I back off after hitting 100 mph!). I was planning on running dual boost - 10 psi regular and 15 psi on demand.

     

    Pfabrications.com sells the turbo for $600. Anyone dealt with them before? Is that a good price?

     

    My next problem is installing an external wastegate. I want to avoid using an external wastegate adapter between the manifold and turbo, so as not to push the turbo closer to the steering gear, and because it would also make the 3" DP even harder to fab. Anyone has ideas or photos of other arrangement for an external wastegate on an S130? In fact any recommendation on who can do a 3" SS DP for me in Queens, NYC?

     

    Again, Thanks everyone!

    Open to suggestions on a turbo upgrade for my 82 280ZX, that would not include major modifications (I can't weld). Would be happy with 300 RWHP on stock bottom end with 100K, so don't really need anything exotic.

     

    Already upgraded fuel pump to Walbro, installed ISUZU IC, and 3" exhaust. Installed oil pump and oil cooler from 81 280ZXT. MS and EDIS in the works.

     

    Plan to do a 3" or 2.5" DP when I can locate someone here who will undertake its fabrication.

     

    All suggestions are welcome.

    Fuel gauge reading OK until I switch to ignition

    Thanks!

     

    It is a 1982 280ZX turbo, with analog combo gauge.

     

    As I remember I ran new power wire to a 30A fuse then a 30/40A relay, then to the pump. The pump was grounded to frame. The relay was originally triggered by ignition. I noticed the pump would continue to run even if I did not start. So I switched my new pump relay to be triggered instead by the original fuel pump relay (the one behind the fusible link).

     

    I will check it tomorrow, but maybe if you or anyone else can tell me the correct way to connect a Walbro fuel pump to the 82 280ZX I can try that and see if it corrects itself.

    My fuel guage will read OK when the car is off, but jumps to empty as soon as I start the car. The inset quarter tank gauge continues to work fine. The connections at the tank looks fine, with no corrosion.

     

    I did change to a Walbro fuel pump, which has its own separate circuit. However, I set the walbro relay to be triggerred by the OEM fuel pump relay - which seems to allow it to cut off if you switch to ignition and don't start.

     

    Any suggestions? Maybe I connected the Walbro incorrectly?
