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.

    • Update for the sake of closure   Ended up getting the intercooler piping all sorted, new plugs and yellow jacket coils, and she was idling mint until it warmed up while I was bleeding the cooling system. Found the misfire to be localised to cyl 3 by unplugging coilpacks, ran a compression test, that checked out, then decided to get a mate to check if that spark plug was firing out of the motor. Upon cranking it over, with the injectors disconnected, the car actually fired and ran on a couple cylinders and heaps of fuel came out the top of cyl 3 I'd say that injector's either spraying incorrectly or spraying far too much, which is fine as I'm planning on replacing them anyway I'm planning on making about 250kW on flex fuel, and have a set of 1000cc injectors from ozautosport, obviously overkill but I'm planning on building the motor and running more boost further down the line, do you reckon they'd be too big for a smooth idle on 98? Thanks for the replies gents, much appreciated
    • I'm confused. You said you want to "remove the clear coat from most panels" but it sounds like you are actually doing a full respray? Few random things to add -  If you chase the blistered paint with 120 grit, I can almost guarantee you'll chase it down to bare metal (that's fine). But if you paint the car from here, you'll have nice little indents where ever the blistered paint was. The new paint won't magically level out the low areas, you need to fill them. Which leads me to the main point I wanted to add, make sure the whole car is flat before you paint it. All those areas with blistered paint you sanded out, make sure to fill them and triple check they are flat with a block guide coat. I'd also check the whole car is flat with a large block and guide coat but yeah up to you if you want to go that far.   
    • 300hp (225kw) is barely outside the standard turbo's range with a bit of extra boost in it (200ish). If you are going to change the turbo you should aim for 250-300kw (330-400hp) to make the expense worthwhile
    • A couple of things, firstly omg that turbo is expensive! $3,000 USD for dinosaur technology is robbery. You could buy a G series turbo and have a good amount of change instead.  If you want a good budget option, have a look here - https://hypergearturbos.com/product/rb25dethighflow/ If you are keen to spend more, have look at the modern turbos, Garrett G series, Borgwarner EFR, etc. Have a look at the RB25 dyno results thread for inspiration.  If you upgrade your turbo to something that will support the 300hp you want and only "probably" have Haltech ECU, your car will only "probably" run. Actually, no it won't run. You are going to need the ECU and injectors at the time you do the turbo upgrade.  No thoughts on "this much boost" as you didn't say how much boost that actually is. Having said that, plenty of unopened RB25's making even more power then what you are chasing.
