Converting My R33 To Manual

Recommended Posts

SECURITY    16

okay so i've done a bit of research on how to get this all done, it sounds simple enough for me so i MIGHT attempt it. either way this is where i'll be dumping all of my info and if i do it myself i'll try and get a step-by-step happening.

my main issue is the wiring, so far i've gotten the following information from different parts of the net.

you have 2 options when wiring - you can cut off the auto loom and solder in a manual one and just connect everything or do the following;

you need to connect 3 looms to the manual box;

- speed sensor, neutral (drops idle/timing to suit), reverse (to turn the reverse lights on).

imagining the box is mounted, the speedo sensor sits at the front of the 3 looms, then reverse and neutral is the last.

the speedo sensors have universal looms so they just plug right into manual/auto without any modifications.

there are a group of five other cables that come off the auto gearbox (near the fuse box).

there are 2 larger gauge wires that need to be soldered or crimped to one another - the auto has a fail-safe that doesnt allow the car to be started in any other place then neutral and park - connecting these 2 wires disables this.

the next ones are the neutral and reverse switches.

these are 3 wires that contain a ground wire. they are colour coded to make it simpler.

green = reverse

white = neutral

black = ground

so to recap, in order from the furthest front sensor to rear on the manual gearbox, you are doing the following;

- speedo connects straight on

- neutral = connect to white wire

- reverse = connect to green wire

- ground = ground the black wire

i'll be updating this with pics if i go ahead and do it myself. will keep this thread updated as much as i can.

cheers,

joe

    i hear that the speedo sun gear is different size from manual to auto. so your speedo may be out. ask the stagea boys, they'd know

  • ive done a little bit of the preparation work.

    - replaced throw out bearing

    - connected braided clutch hose to master/slave

    - installed the manual pedal - the holes are on the inside of the cabin. just centre punch and drill them out. i managed to do it without taking the dash out, but i'll need to do it to fit the manual brake pedal (but it can wait).

    i've got my redline shockproof oil ready to go. i just need to get the car high enough to start.

    First of all, thanks to SECURITY for posting up his information. The wiring stuff made the job heaps easier. some pictures posted by pal of the wiring needed to be done in the engine bay were a big help too.

    post referning to Pal's pictures is here -> http://www.skylinesaustralia.com/forums/topic/285791-manual-conversion/page__st__20__gopid__6255165#entry6255165

    just to add my experience, i have a S1 and i bought the manual stuff from a S2. everything fit straight up except for the tailshaft. as i have now learned, the S2 i got my parts from had ABS and hence the diff snout is a little longer due to the ABS sensor so when i measured the rear half of the tailshaft from the S2 it was about 15mm shorter that the rear section of the series 1 hence will not fit. so i got a S1 manual tailshaft complete from my local wrecker and solved my problem.

    Hey all I’ve just done an auto to manual conversion on my R33 sedan however the mechanic didn’t have the right loom to connect up the reverse and neutral sensor wires. I’m going to do this myself but I’m having problems with finding out what colour wires from the fuse box I need to connect to. Can someone please help? 😁
