    Z32 transmission install .. number 3

    in Nissan L6 Forum

    Posted

    I'm posting this in ALL 3 threads regarding the Z32 transmission swap

     

    We can still use the FACTORY speedometer with the Z32/RB25 5-speed transmission swap!!

     

    Mike Rowe was able to find a mechanical speedometer pinion assembly (Nissan part number 32702-02G17) that came from a Nissan Hardbody (D21) truck... with the manufacture years (1986.5-1994)

     

    This replaces the electric speedometer output.. and converts it to a mechanical speedometer output!!

     

    Incredibly.. the speedometer cable bolts right up to the new pinion assembly and it works!!

    I think it cost me around $46 from Nissan =)

    Sometimes you GOTTA wonder...

    I've noticed some of the schools valedictorians and incredibly talented engineers and unbelievably gifted individuals have no "street sense"

     

     

    I've always been blown away how dumb and retarded they can be. Even the simplest tasks in life and everyday common sense occurrences seem close to impossible.

     

    Book smart but that's it. They be street stupid ha.

    can't get rid of stumble MSnS??

    sounds like Acceleration Enrichment's possibly?

     

    I also have slight issues with my car stumbling too..

     

    are you TPS or MAP accel tuned?

     

    I dont think it would be the turbo at all.. if you had a turbine jet engine I would say its a symptom of compressor stall.. but in an automotive application this doesn't apply

     

    from : Wikipedia

    A compressor stall is a situation of abnormal airflow resulting from a stall of the aerofoils within the compressor. Stall is found in dynamic compressors, particularly axial compressors, as used in jet engines and turbocharged reciprocating engines.

     

    Compressor stalls result in a loss of compressor performance, which can vary in severity from a momentary engine power drop (occurring so quickly it is barely registered on engine instruments) to a complete loss of compression (compressor surge) necessitating a reduction in the fuel flow to the engine.

     

    Symptoms in a turbocharger in a recip engine are not as wild as jet engine stalls.. but a sudden surge or "stall" in performance is applicable

    Disappointing 1st time at the 1/4 mile.. blah

    I am running an open 3.54 R180 from the '78 automatic drivetrain

    AFR's under boost remained from 11.2-12.3 AFR in all gears.. no detonating

     

    In regards to shifting, I would would at 6,200 RPM

     

    I just realized that my rear shocks were set to (3) out of 5 on the tokico illuminas.. which might have been too stiff!!

     

    My launch consisted of a 3,000 RPM, no brake or clutch applied... light turned green and i feathered the clutch and throttle for an attempt of minimizing wheel-spin. My e-brake is temporarily disabled lol.. and I was too nervous to try to hold the foot brake and slip the clutch my first few runs.

     

    3 runs.. with almost an hour and a half of waiting between each run in the staging lanes.. it sucked.

    Tonight was my first night ever going out to any sort of drag strip..

     

    I had a chance to do 3 runs.. it was at Bandimere Speedway which is around 5,000 ft up in altitude..

     

    Here are my specs :

     

    stock un-touched F54 block P90 head

    Schnieder cam .488 lift 260 duration

    2mm headgasket

    Holset HY35W turbocharger

    MegaSquirt n Spark extra

    Isuzu Diesal NPR intercooler

    2.5" intercooler piping

    4" downpipe 3" straight through exhuast

    Tokico Illumina 5 way adjustable struts

    Arizona Z car springs 205f/225r

    205/60 front 225/60 rears - Yokohoma YK520 tires (26psi in the rear)

    ACT Stage II clutch and pressure plate

    Fidanza aluminum flywheel

    Z32 transmission

     

    Im assuming my shitty tires are to blame 5%.. but overall I SUCK at driving. Boost was 15psi (at 5,000 ft which is roughly 12psi at sea level)

     

    I was expecting 13's maybe 12's.. but damn!!

     

    60' - 2.468

    330 - 6.386

    1/8 - 9.472

    MPH - 80.86

    1000 - 12.037

    E.T. - 14.204

    MPH - 108.31

     

    With such a high trap speed I was hoping to get more out... I dunno someone bench race me!! I would think the car would be much quicker!

     

    I tried launching at 3,000 RPM and being nice to the clutch.. but I spin through 1st and also in 2nd. ugh. Shifting was done at 6,200 RPM

     

    Thanks Bobby for filming me!

    Problem solved!!

     

    I ordered 2 new NISSAN bushings.. and a Shifter collar/support rod !!

     

    Now the shifter doesn't have any play at all!! The support rod is the same diameter as the bolt now so voila!!

    The 2nd pic shows the bushings and rod installed!! Notice the white bushing above the shifter? The white one is the Fidanza unit... notice how large the hole is?!? no wonder the bolt was moving around!!

    Silly q - VB921/BIP373 required for 2.2 PCB EDIS?

    in MegaSquirt

    I have been reading the megamanual a few times but I couldn't find a definite answer...

     

    with MS1/extra and 2.2 PCB board.. and EDIS 6 ignition... do I need the VB921/BIP373 coil driver?

     

    None of the EDIS wiring 2.2 PCB board specify if I need it!!

     

     

    EDIT - this might of answered my question

    EDIS is a particularly easy way to replace distributor ignitions when retrofitting older engines with a modern computer programmable ignition, but we now recommend directly driving the coil packs from the MS ECU using the VB921 FET's. This does away with the EDIS module, so all thats needed is the 36-1 wheel, a VR sensor and the coil packs

     

    So if I run the EDIS module I do not need the VB921/BIP373..

    I can have MS ECU control the coils using VB921/BIP373 by throwing out the EDIS 6 module and using just the coil packs and VR?

    help!! The car runs for a few seconds then dies after wild tach reading..

    according to the logs and what Megatune shows.. the intake and coolant sensors are reading like normal.. no spikes..

     

    The AFR's are also normal.. the car idles around 13.5 AFR ... then the tachometer shows wild readings.. the AFR still shows 13.5 AFR.. then its like the fuel/spark both get cut off at once.. so the AFR goes to 20.1/O2 which is the calibrated O2 value without the engine running.

     

    Im considering going to EDIS now lol
