Hey guys,

I have changed my throttle body and i need to set up a tps for it.

I have an rb20 engine and have changed my throttle body to an xf one

I have noticed that the xf tps ranges from 500 ohms to 4600 omhs, but the rb20 tps ranges from 2000 ohms to 10 000 ohms.

Is there any way that i can modify the out put of the xf tps to turn it into that range?

Maybe using resistors or something?

Thanks for any help

Nah no aftermarket computer

I don't have the rb20 tps any more, it got sent out in the rubbish thanks to my brother

I have put power through the tps.

The idle voltage is 1.85 V and the fully open voltage is around 10 V

Is there anyway of changing it at all?

Like something where you can set the starting resistance at .5 V and set the end at 4V and it controls the in between from this information?

Thanks for any help

Not real sure on nissan computer signals but I think the computer will be monitoring the voltages and not the resistance.

Sounds like Xf TPS = 0 - 10 volt and Nissan = 0 - 5 Volt absolute readings.

Both are industry standard signals and you can get simple convertors for the task of scaling these voltages, even a 0 - 5V convertor will easily be adjusted to give you 0 - 4V if that's what you really need...

If your even a little handy with a soldering Iron I think you can buy a build it yourself kit from Jaycar or similar prolly from around $30...

Hope this helps.

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
