    88 wd21 to vg33 swap

    in 86.5-89 WD21 Pathfinders

    Posted · Edited by Gorgonheimer

    Currently going through the conversion of the VG30e to the VG33. Unless you are an automotive electrician, you're opening up a huge can of worms.

     

    The issue with keeping the same components on the VG33 is that you will need to rewire/re-plumb EVERYTHING...Alternator, PS Pump, AC Compressor...not an easy fix.

     

    The advantage of the VG30 intake swap is that you can keep the same harness...This is a PRO/CON, and my opinion only...but it does make a few things easier...

     

    That being said... I'm planning on keeping the VG33 injectors...they have a higher flow rate than the VG30 injectors...however..I'm honestly not sure if the ECM will take them into consideration...still doing alot of research on that. Trick here is that it's requiring me to rewire the harness for the injectors. I have a good amount of aviation/aircraft wiring experience, so I'm ok with this...but it's not for a novie. Think it through.

     

    Definitely keep the cams from the VG30...after pulling both sets of cams and mic'ing everything out, the VG30 cams have a larger lobe dwell, which means more air, exhaust, etc.

     

    So far, everything else is bolting back on the VG33 like clockwork...

     

    I have a thread started on this conversion here: http://www.nissanpathfinders.net/forum/topic/43545-vg30-to-vg33-swap-step-by-step-starting-today-82617/

     

    Apparently there are some image problems with it so I'll be fixing those later this evening...plus making alot more updates...

     

    No b.s. I am an auto electric guy. Really a drivability tech.

    the reason for ditching the manual, i was thinking i am going to have to use the VG33 management, which has provision for auto.

     

    my power loss would come from using the TBI on the VG33 and not making the power that vg33, with its own management, is capable of

    engine in my 88 crapped out, and i have an complete r50 to pull drivetrain from. Any one done this? Ive read that it will bolt in no problem, but i am wondering about engine management.

     

    Option 1: use vg33 and accessories, vg30i intake and management, pros; retain manual trans. cons; possible power loss with TBI setup

     

    Option 2: use all vg33 stuff from the r50. Engine, auto trans, tcase, harness and management. pros; Get OBD2 and 40 more horse. Cons; lots of wiring

     

    Thoughts? ideas? tips?
