i knwo he was trying to get some info from a supra forum, but couldn't get the pictures to work, never heard from him if he worked it out..

only thing i saw was him start the car and turning the TPS with his hand to make sure everything was working.. lol

ive figured out what the wires on the q45 tps are,

does anyone know what the wires on the stock rb25det II are? colours and description

craved- i found my information from a supra forum 2, pretty useful

this is what i uncovered so far

on the q45 tps- plug that runs off the tps

Red is the 5 volt input wire

White is the TPS signal wire

Black is the sensor return wire

so i need to know-

1-what wires to match these to

2-also the second plug (wot) of the q45

cheers,

try pauls site, see in the diagrams section there is a engine wiring diagram

http://members.dodo.com.au/paul/

see if you can decipher it.

lets us know how you go

craved, your a legend!

pauls site helped alot (cheers paul), so now i know all the wiring on the rb (WOT + TPS) and the tps of the Q45. but i still havent got the WOT diagram or wires of the q45

its a 3 pin plug which would include:

1,throttle valve switch(idle control point) IDLE

2,throttle opening output signal SIGNAL

3,throttle valve switch (power supply) FULL

ANY IDEAS PEOPLE?

the plug on the tps body is for wot and idle.

take a multimeter and have at it, center pin is common ground for the two so from what i remember if the tps is face 'down' (brass bit down that is) then the idle is on the left of center and wot at the right of center...

i might have that reversed lol...

Here is the diagram guys.

Very simple

tpswiringdiagramforrb25tovq459.jpg

dsc002940fc.jpg

In the picture and diagram it illustrates the way it sits in the car attatched to the plenum which should be always upside down to suite the throttle cable layout but it all depends on the plenum.

But to under stand which way the vertical wires are on the plug.

So from top (bonnet side) to bottom (ground side) on the plug

Green

Black/White (Can also be just black)

Red

We had a custom one made up by a shop on the Gold Coast.

Sounds funny but most large Boat shops can make up throttle cables.

You just tell them the throttle cable length you want and how much inner and outer lenth you want for the sleve.

Wgich is what we did.

Some ENZED's also are able to do them.

:(

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
