Hi ppls,

I am about to attach my Z32 to the R32.

Upon inspecting the origional AFM wires I found some thing a little strange.

(see pic)

Is this normal for an RB20t to look like this (2 wires going in to 1 coax)?

I've attached the R33 S1 wiring instructions pic that will work with my rb20t as I've had a R33 S1 AFM on my R32.

The wiring instructions don't state the pinout for the r33, only the pinout for the Z32. :P

Would any one know the pinout for the R33 S1/R32 AFM.

I wouldn't want to run 12v through the signal. :cheers:

Thanks ppls.

I will have a look tonight Joel, I remember I used that diagram, plus a few other things I wrote down in my little car book I keep,

I know for sure the coxial part of the cable was not required to be soldered to anything, mine looked exactly the same when I stripped back the black plastic

will post it up tomorrow

No probs

I remember Roy telling me about a certain workshop in Vic that was swapping wires on his AFM while the car's ignition was on to work out which was the right one! Dodgy!

I've been doing a little fiddling ( not wire swapping :D )

It appears quite straight forward.

The Coax shields both the signal and signal ground (Unlike the Z32).

Pin outs are exactly the same. ;)

I need you to still confirm it if you can Chris. :rant:

It is still running on the base map so i'm unsure if anything will change when it is tuned Tuesday next week.

lol.. A free rev to 5000rpm hits 100% duty cycle. :( Can't work that one out, mind you it is boosting on a free rev. lol

Shall be very interestering how much power it makes on the stock turbo @ 11psi.

It feels much quicker than the rb20det running 16psi. :(

The AFM voltage in the sensor check definately reads lower.

The highest it now reaches is just over 4v.

With the rb20 afm it was hitting 4.98 volts. :P

So it must be doing something.

Just strange how the load points on the map still read the same.

It will be tuned with the std turbo on 11psi. bar & plate FMIC & 3" turbo back exhaust, std injectors, std airbox + 100mm cai into the inner guard.

It is just a 1hr quick tune to tidy up the map and throw a little more fuel in the bottom end and mid range. :D

I dont want to spend too much on the crappy std turbo. Only to see how it goes with the 3ltr out of curiosity.

I'm keen to see where peak power is made, I've heard of some making peak power (150-170rwkw) around 3500-4000rpm.

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
