Aftermarket Lightweight Pulleys, Do They Really Make A Difference?

Hey guys,

I own a R34 GTR, recently my power steering belt snapped so i took it back to my dealer because it was still under warranty. They told me that the aftermarket pulley that was on my car was made for a R32, thus the reason why the belt came off. Okay true, i understand that bit.

After a few days, i headed down to the dealers mechanic to pick up the car, from what i can see the pulley was replaced but strangely enough i noticed that the balancer was also replaced. I was running an after market one from what i could see when i first picked up the car. (They told me they didn't change it, and only replaced the pulley and the alternator pulley but the aftermarket alternator pulley is still there)

Anyways, driving the car back it felt very different, it was no as responsive as it was before, it just didn't have that little edge it once had. (Noting that the car was tuned, Power FC, cams, and full exhaust)

I was just wondering by changing the pulleys back to standard would it make that much of a difference that i can feel a change in power delivery? Or was my assumption of them changing the balancer as well contributed to the change of responsiveness i now have in my car?

I am pretty upset about this as I have no proof to say they did and I did trust them enough to leave my car to them.

Any help will be greatly appreciated.

Lightweight crank pulley = less rotating mass for the crankshaft to turn. Might free up a few kw depending on how much of a weight difference there is between stock & aftermarket. I have one on my car and it makes a small but noticeable difference.

Thanks for that, when i mentioned pulley they replaced the aftermarket crank and the power steering pulleys. Was that necessary if it was only the power steering pulley that was not aligned properly?

the name was rocket something... or vise versa. the reason i knew is i had a look at it before i took the car there, and when i had a look at it again at the workshop it was sitting in the passenger side floor and i had the stock one put back in.

That's what i thought, only the power steering required changing. Damn got robbed.

The thing that got me was when i asked for the parts back i was told they never replaced it when it was obviously clear it was. All the belts were changed back to stock as well.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?

      M35 Brake caliper replacement

      By Duncan · Posted

      You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items

      Jacks that fit under GTR lips that can reach the subframe?

      By Duncan · Posted

      Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
