i also heard of this happening so i got a stainless one fabricated for me for 100-150 cant remember when i put on a Z32afm and a few other things, being stainless it looks good as well as serves a good purpose... also it stops the pod from moving so i didnt need to put a bracket to hold it steady.. didnt think the price was too bad

can anyone confirm that the stockR33 turbo will need a 3-2.5 inch silicon reducer?

Ditto, i would really like to know the same thing before i go and buy the wrong one, i just need confirmation that the stock turbo inlet is 2.5"??

Cheers

P.S, i should hopefully be starting sometime this week and will be using 3" polished alloy pipe insteas of stainless

i had my stock rubber pipe on and made 191rwkw wit usual mods + safc and gt2535 on 14psi ona r33, changed my plugs and took my stock rubber pipe in2 an exhaust place, the copied it, changed me $40, also put the small pipes for the plumback and oil breather.

slaped it on and got a retune and made 200rwkw, plugs wouldnt have made me more kilowatts, so the $40 must have made me some power as i didnt touch the engine before

Definatly agree with changing it to make it more solid. One of the guys at my work had it happening to his 180sx. He said he just fed in a steel coil spring like thing. No problems after that. But personally id go the alloy way. If your gonna go through the hassle of playing around with it u may aswell change it all together, not to mention tidy it up a bit. In my opinion the stock rubber pipe is an ugly piece of sh*t that lets that side of the engine bay down and makes it look cheap and nasty haha. Metal will make a world of differance

Finally i have found out what size the turbo inlet is, thanks NYTSKY for measuring your turbo for me :D, it is 59mm which is 2.25", so i have just ordered my 3" 90degree alloy pipe and 2.25" -3" silicon reducer, hopefully i will have this finshed sometime this week if im lucky, i will post pics of the finished product.

yes the turbo inlet is 2.25 inch,

I have fitted a 3 inch metal pipe and the car doses but not what i expected, im gonna try get a brass pipe thats 2.25 inch and see what happens.

Doses?? wtf??

And what do you mean by "not what i expected", does the car run fine or does it run different to when you had the stock intake pipe?

by dose i think he means like flutter (dose = vl talk ie rubbish)

also why would you go brass? the material used wont change sound and id rather go 3" to 2.25" it would be forcing the air in more aggressive in my opinion.. 2.25" all the way seems like a waste, i mean the outlet for afm is 3" why go smaller??

I hear that the material that the pipe is made of and its thinkness makes a difference to the fluter sound, with a 2.25" pipe the flutter should sound different which is what I want and performance does bother me because im doing it for the sound-experiment

  • 2 weeks later...

Good news, i finally finished the intake pipe an have taken lots of pics, i made it so it fits up to the stock airobx and i can also use a pod aswell

The parts i used were: 1 x 3" 90 degree 600mm long alloy bend, 1 x 3" 45degree silicone joiner, 1 x 3" - 2.25" silicone reducer, a small length of alloy pipe that is the same size as the stock plumback pipe,some radiator hose from super cheap (i think it was the bottom hose from some triumph, it fits the stock plumback line perfectly) some old plumback line that i had leftover from when i installed the RIPS plenum on my old car,some clamps, 1 x local engineer for the welding lol

Heres the pics

The pipe was 600m long so it required a lot of cutting to get to the exact length

I had a little peice of alloy pipe welded on the bottom of the intake pipe which connects to the modified plumback line, i was orginally going to have the plumback line connect to the top of the intake pipe just like it is stock but there wasnt much room so i decided to do it this way.

How it looks from underneath the car

Modified plumback line, this was a bit tricky to make as it had to clear the aircon pump bracket and then curve underneath the intake pipe, it needed lots of cutting, rotating and welding, it was probly the most diffucult part to make work and look stock

The kool thing about it is you cant see it in the engine bay unless you have a really good look

The car runs fine with it , i have only tried it with the stock airbox at the moment and the induction noise does seem to be a bit louder, i have not tried it with a pod yet though.

That looks really good mate, I'm thinking of going back to the standard airbox like you've done. That looks almost factory if the hoses and pipe were black.

Cheers mate, i was originally going to use black joiners and paint the alloy pipe black but i cudnt find any black silcione joiners, you can barely even see the pipe/joiners ,you would never know its there unless you have a real good look.

^^^ Thats exactly what i did to mine as well...good job...only difference is that i bought the pipe with the BOV plumbback and breather fittings already welded on...which made it a pain to adapt to the standard hoses...but nothing a bit of backyard ingenuity couldn't fix...

    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
    • Well this shows me the fuel pump relay is inside the base of the drivers A Pillar, and goes into the main power wire, and it connects to the ignition. The alarm is.... in the base of the drivers A Pillar. The issue is that I'm not getting 12v to the pump at ignition which tells me that relay isn't being triggered. AVS told me the immobiliser should be open until the ignition is active. So once ignition is active, the immobiliser relay should be telling that fuel pump relay to close which completes the circuit. But I'm not getting voltage at the relay in the rear triggered by the ECU, which leaves me back at the same assumption that that relay was never connected into the immobiliser. This is what I'm trying to verify, that my assumption is the most likely scenario and I'll go back to the alarm tech yet again that he needs to fix his work.      Here is the alarms wiring diagram, so my assumption is IM3A, IM3B, or both, aren't connected or improper. But this is all sealed up, with black wiring, and loomed
