    Help with 280zxt ECU swap to 300zxt ....

    in S130 Series - 280ZX

    Posted

    OK so I went to wrecker got the extra pins I needed for the ECU Swap on my 280zxt.

     

    Now Im trying to hook up MAF wires heres my Layout.

     

    A: White/Green

    B: White (But has a Black overcoat with silver wire inside? sheilding?)

    C: Black/ Large red paint spot

    D: Black/ Small red paint spot

    E: Yellow/ Red

    F: Red/ small red paint spot

     

    Now this MAF harness is from a Maxima VG30 but I marked colours and ABCDEF positions.

     

    Now my 280zxt Harness had these colour Wires.

     

    Yellow/Blue (AFM 34) (ECU 33)

    Black (AFM 33)

    Yellow Red (AFM 32)

    Yellow Black (AFM 25) (ECU 30)

     

    Now in AFSHIN's Post:

     

    A: W/G (VG30 Maxima) goes to Yellow/Black 280zxt harness

    B: W/ with black insulator goes to Yellow/Red from 280zxt harness

    C: B/With large red paint spot goes to Body Ground

    D: B/with small red paint spot goes to Black wire from Z Harness

    E: Yellow/Red goes to VCM black with white stripe under old AFM

    F: Red/With small red paint spot goes to ECU's 33 yellow/Lime wire

     

    Now my problem is my old harness wire YELLOW/BLUE is not mentioned, so what colour on my harness goes to Yellow Blue (which ends up being pin 33 on ECU

     

    so confused lol

    Long over due update on my ZX, (retitled from "Hey guys and gals")

    lol

     

    Ty for title.. I'll be posting my 81 ZX for Parting or whole car to. But the floor pans are dying of rust and the frame by the floor pans. I cut all of it out so just needs that Pan kit ect ect. Engine runs great still went its stock 130mph. Im just taking the tranny 5speed for my Automatic Turbo swap. but if anyone needs some crap from it let me know. Ecu harnesses blah blah blah let me know hehe

    Ah yeah the upper coolant line form the thermostat right.. Yeaaa good Idea.. Plus the TB I have has a top through line so I can snake it over that and then down I suppose. As for the PS pump ty for idea. Ill try that. I have a 280zx 1981 with recirculating ball or whatever (manual armstrong steering) but I hear it might hit the turbo so thus asking around for ideas.

     

    TY for input though! will deffinately get rid of the PS and route those cooler lines

    So I'm about 5 years behind on this mod. But I just got the car a few months ago so... hehe

     

    So Far:

     

    Installing the 300zxt ECU (1987) today using male to femal connectors and solder to make sure everythign stays together =-)

     

    Ported out my manifold to 65mm and installed the Maxima 65mm TB

    Ported manifold to Head ports 32.5mm and matched to head 32.5mm

     

    Took a 300zxt Turbo and cleaned it up mounted on Exhaust manifold and used the 280zxt Wastegate & adapted it tot he 300zxt compressor housing so the 280zxt downpipe works with my 3"Exhaust piping.

     

    Changed all the old 280zxt Injector pigtails to 300zxt ones because they were newer and not cracking.

     

    Bought a 10-140psi Fuel pressure regulator off Ebay that I will mount on stock rail.

    Changed all fuel rubber lines to new.

    Replaced all rubber vacuum hosing.

     

    Still have some questions of were I should tap inot regarding Cooler lines for turbo as the 300zxt turbo has Coolant lines. Ideas anyone? *I was thinking T off the line going to theHeater core and wrap around back of the engine to the turbo then L back around and back to that line again .

     

    Cant find any decent Injector prices so might have to save up and remain Low on Boost.

     

    Ordered a Big FMIC intercooler 24"W x 12"H x 4"T (going to have to make up some piping for that int he next few days.

     

    Going to adjust Valve lash sometimes today or tomorrow, Diconnected PS pump for now as its leaking. Question? can you run that rack without pump or should I replace pump soon and just keep filling it. I think bearing going on it from the sounds of things.

     

    Iridium Plugs

    NGK Wires

    Magnaflow 3" exhaust

     

    Painted everything lol well almost

    Valve cover : Silver with Red turbo Writing

    Intake manifold: Silver

    PopOff Valve (modified to accept 12psi): Dark Blue

    Exhaust manifold: High temp Black

    CLeaned oil off block and the original blue paint appeared wow!!

    Turbo: Silver like the intake mani.

    Thinking Ill Remove bumper.. As of now I cut out the middle section to place intercooler in there but trying to track down some type of body kit that will briten up that front end.. Dont liek the 82 style front bumpers.

     

    any suggestions? let me know.

     

    also Anyone know of specific wheel flares that work with the 280zxt. Cause I'm getting a tad of wheel well rus so I was going to cut it out and flare them a bit.

    HELP AFM swap to 280zxt

    in S130 Series - 280ZX

    OK the AFM I got was off a 87 Maxima with a VG30. Issue is.

     

    The harness that came on the car has 5 Pins with a Slot for 6.

    Now the AFM only has 4 pins?

     

    So why did the harness come with 5 pins and the AFM with only 4.. None broken =-)

     

    I opened the AFM up and see 4 pins going through to the board all with some tpe of resistor before board and a 5th hole but nothing to board. Now dose this afm have some type of auto clean cycle? or something that it dosent need the 5th and 6th pins?

     

    also it was obviously not a Turbo motor. But my ECU is a 1987 Turbo ECU and I have everything else including the chopper wheel so will this swap work with this 4pin NISSAN AFM?

     

    THE AFM pins are located on BCDE so A and F are missing.

     

    OK went back to wrecker found a oldschool 1986 Maxima with a VG30 and vwala!! 6 Pin MAF with 6 Pin Connector!! yay!! Freebie!!

    shaved intake 280zx, now won't start

    Yes Service manual. And looks like some grounds arent connected. Hosing dosent look right. hmmmm you didnt leave anythign in the intake right hehe just asking .. it happens. ummm Wires all right order? also Try adjusting the TPS or AFM check plugs what do they look like.. soiled? black? SO many things man... and that tube on bottom of manifold is open if I heared you correct if you have open airflow past the TB and the AFM then its gonna totally read the wrong airflow cause it will be sucking in air from any open holes and bringing to much air in thinking its running fine lol.. ooh wait I looked again I thinkg thats the Block tube.. not sure try to keep pics on same angle.. my neck hurts lol.. also is that hose coming from the fuel pressure regulator hooked up? looks to be just hanging down to no where...

    New to Hybrid and got some questions about compatability and swaps

    in S130 Series - 280ZX

    OK.

     

    First off hello all. I have loved Z's since I was in grade 6, and while walking to school I watched a guy prolly about my age now (29) rebuilding a 260Z in his front lot for over 2 years till i went to highschool. when he finished I was walking by I noticed he was cleaning it and I said.. "what kind of car is that".. He replied with a smile... a 260Z.. and offered me a ride to school.... yep hooked...

     

    Long story short, I found my first Z a 1981 280zx N/A which I lightly tuned up but it is dying of underbody rust. SO after buying several more Nissans from 200sx's to 240sx's I happened upon yet another 280.. This time the great L28ET.

     

    its a 1982 T-Tops and im am the 3rd owner. So everything is still in tact even the Injector fan cooler thingy =-)

     

    But as I have been into modding for years its all got to go!!!.. lol.. SO

     

    Its an Auto first off (ahhh!!!) but I still own my 1981 280zx N/A with a 5 speed manual so Im gonna do the swap before I hit my 1st and 2nd years of Automotive Mechanics.... Also since im on EI and waiting for school I have 1 month to make some magic happen.. Now.. List of parts I have obtained from the scrap.

     

    According to "Afshin" I needed..

     

    Dizzy (I got a 1987 Maxima)

    Ecu (1987 Turbo 300zx freshly crashed)

    Turbo( 1987 300zx Freshly crashed)

    MAF (1987 300zx)

    Basically everything on the shopping list needed for the Z31 ECU swap into a s130T

     

    Now. I have customed a 3" exhaust myself witht the pipe bender at work with literally no bends other than under the rear control arm which even then I angled gradually to keep it almost straight and complimented that with a Nice big Magnaflow exhaust.

     

    Did a bunch of regular maintenance IE (Diff fluids, brakes,blah blah blah)

     

    Now I have taken off the manifolds and turbo swapped some turbo components from the 300zxt turbo and 280zx turbo to make one nice one.

    Ported the Turbo (everything lol did this to my talon turbo to made it spool much nicer) I am going to increase the Jpipe to 2.5" (Fab one up) Modded the pop off valve to accept about 12psi before it opens. Removed EGR

    Found a VG30 (Maxima 65mm inlet to 60mm where it joins manifold) throttle body. which I then took Motorcycle brake cable and flipped the throttle body upsidedown allowing direct connect to Intake manifold without spacer and linked cable to the old linkage at firewall. kinda neat for $33CDN total. Ported the manifold obviously to 60mm tapered to accept 60mm TB. Ported intake manifold to Head holes slightly larger to allow more flow and Ported Head to accept the flow. K/N filter cant find my old Talon intercooler yet so havent fab'd that in place yet so will run obviously around 10psi for now.

     

    Now... I couldnt find any injectors as of yet to handle more power in future so just might buy new for peace of mind. But! has anyone tried to put HICAS on a 280zx from a 240sx and also has the reliability of the ECU swap held up for all who have done it?

     

    Ty for your reading time I will be posting some pics of TB swap porting done the patient but backyard way lol and other such things. Lotsa painting litsa wirebrushing to go yay!

     

    Least this one came with only about 4.5% rust none on underbody.. Miricle I know!!!

     

    Of forgot the other question!!! or more blabbing.. Ok the 300ZXT turbo has the additional water cooling soooo where would one hook that into? prehaps off the cold start valve tube? Cause my TB has the through pipe ontop and I figure I could t one line off from there to the turbo or should I just let the oil cooler lines to the turbo do it or what!!! kinda swampped with all the ♥♥♥♥ im doing so hard to concentrate need other minds LOL.. Im thinking I could just T it off some line somewhere maybe to heater core go around back of engine to the tubo and then link in somewhere any ideas? Cause a Coller tubo is a lasting turbo right!!! lol
