"Airtemp sensor on unsupported car?

Some PowerFC's have support for the AirTemp sensor under MONITOR but the car itself does not utilize a factory air temp inlet sensor. I attempted to hook up an airtemp sensor on my ECR33 PowerFC and fried the powerfc and damaged a sensor on my car. The concept was to look at which pin on the BNR33 PowerFC the air temp sensor was connected on and then try and replicate this on the ECR33 PowerFC. I tried this and it did not work, I tried an adjacent wire and it fried the PowerFC. It has since been fixed and all is working but I do not recommend you try to get this working. It may work out costly like it could have been in my case. "

Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

Yes this mod works fine for BNR32 + HR32 PowerFC. Only ECR33 PowerFC it goes bang

haha yeah good idea

shoulda seen the look on my face when i had pacman characters running around on the hand controller screen and pshyco ticking noises coming from the powerfc

im sure that would have been followed by some VERY colourful words :lol:

hey guys. im new to sau, but i jst thort id thro my 2c worth in... im currently building a rb25/30 setup, using a complete factory rb30et bottom end, crank rods and pistons, rb25det head, my current hi flowed xtr turbo,850cc powerflow injectors,haltech ecu, rb26dett water pump, stock oil pump, thru a r33 gtst manusl box...iv been told it will be good for 3/320rwkw...duz this sound rite 2 u?

If it's a high flowed RB20DET turbo it will run out of airflow at around 260 rwkw

If it's a high flowed RB25DET turbo it will run out of airflow at around 270 rwkw

If it's a high flowed RB25DET Neo turbo it will run out of airflow at around 280 rwkw

That's not your main problem, the RB30ET pistons with an RB25 head will have very, very low compression ratio (in the 7's). That's why we use the RB30E.

:P cheers :(

with the rb30e, are the stock rods and slugs strong enough to take the beating? or a $2500 aftermarket jobs the go? think cheap, thats wat im trying to do.... i know i know, cheap usualling ends up being "cheap", but i dnt av THAT ammount of money lying around atm...

I just want to build a torquey motor, turbo upgrade can wait. so 270kw? a the wheels im guessing? why did this guy tell me 320? is he just having a wank? or is he just trying to get work from me?

This pic illustrates the close curved lines a little better.

Sorry Geoff.. I don't follow the Cap'n... :rofl:

Do you mean repeated high load that attempts to and may very well slightly bend the teeth every time?

A little like breaking a coat hanger by bending it repeatedly.

So definitely rb30 related?

Sorry mate, I missed the question. Wasn't meaning to be rude.

Basically all steel things have a fatigue load limit. Below that load you can load infinitely (faults notwithstanding) and it won't fail, but increase the load, or in this case torque, and eventually it will start to crack slightly more and more each load cycle until the cross sectional area holding it is too small and just lets go, like the coathanger.

The rb30 vl type blocks dont have oil squirters. only the rb20,25,26 have them. a lot of ppl put the rb25det squirters in the rb30 conversions tho...

It's a bustard of a job (= costly), and only about 2 in 10 RB30 blocks are suitable. Ceramic coat the piston crowns and oil retention coat the skirts, just as effective.

:rofl: cheers :D

      Question about R34 GTT A/T Solenoids

      By DraftySquash · Posted

      So.... when I'm finally getting around to having my power steering leak sorted, now it looks like I've got the same issue most A/T Skylines are having. My A/T light will randomly come on and I'm stuck in 3rd gear until I turn the car off and on again. Only 3 weeks ago I did a complete transmission service: Oil flush + new gasket + new filter. This came out of nowhere!! It wasn't like the car was driven hard. I drove about 3 mins down the road to get fuel and boom!!!  Anyway, I have a few questions and hope you fine people can help me out here. All questions are in red. 1. The solenoids: I was looking at the parts catalogue in Amayama and I could only find the Solenoids as an assembly. https://www.amayama.com/en/part/nissan/319404ax05 I read in another thread that Solenoid A = 31940-4AX02 & Solenoid B = 31940-4AX05 but the Amayama product has only the code of B. Is this the right part? Can anyone who has done the Solenoid changes or seen them confirm if this is the complete set of A & B?   2. Gasket and Filter: I'm not going to try change the solenoids myself because it seems difficult to do in a home garage with just 2 jack stands. I plan to take it to a shop and get it changed. I was also going to buy the transmission sump gasket at the same time so I don't reuse the same gasket. Should I just use the existing gasket as it has only been on the car since OCT 19th? (~3 weeks) Should I be buying a brand-new gasket and a filter? Does this job involve taking the filter out?   Thanks in advance to everyone. It's hard to find a video of someone doing a solenoid change on a R34 so any help you can give answering my remaining questions would make me less stressed.

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By Kinkstaah · Posted

      Yea - From what I have seen from the video, the car idles like any R34 lol 50PSI of fuel pressure is hardly super abnormal, the regulator is working because the pressure remains static when the throttle gets revved, i.e pressure remains the same when manifold vaccuum changes. Bigger pumps on stock rails always bumped the pressure in the rail without using an aftermarket regulator to change that. Do you know what your IAC is actually doing? Has there been any data showing the stepper motor % etc? There's no way your idle is actually moving around the way the cluster(s) are indicating. You would hear the difference with the engine RPM flying to 3k and 1k in mere seconds. I'd be checking the wiring to the tacho. What the tacho is telling you and what the engine/ecu is telling you are different things. I assume your ECU doesn't display the spike. So whatever is telling the tacho to be at X rpm is doing something weird. When the going gets insane, you're on the wrong path. You've ruled out plenty of things that are working correctly/aren't the issue. Your idle isn't doing what the tacho is indicating. You have two seperate issues, I don't think they are linked, and the idle seems reasonably okay unless it's stalling which.. well, it hasn't. Troubleshoot the stall if it occurs by figuring out what your IAC is doing vs what it is being told to do.

      ER34 RB25DE Auto - Would a flush ever fix an "A/T" light?

      If it has had a code in the recent past, the code should still be there waiting to be read.
