Hi All

I bought my first skyline yesterday (an R32 GTS-t) and i have a few questions (already :Oops: ) about things i've noticed...

Do these cars have a factory boost cut? I've noticed that if i get up it a bit in like 2nd or 3rd (or 4th on the highway), higher in the rev range (i.e. above around 4.5k rpm) and around 12psi (it has a catback exhaust, pod filter and BOV... can't see a boost controller in there anywhere... does the amount of boost sound right?), it feels like its hit a wall (i.e. a boost cut type thing) and seems to lose power, exhaust pops (like its running rich) etc... is this the factory boost cut? do they even have a factory boost cut? or is it something more sinister? :confused:

Also, i've noticed that my Hicas light comes on on the dash intermittently, but if i switch the car off and restart it, it goes away... the car does have an aftermarket steering wheel (which will be replaced with a stock one soon) so i'm hoping its just a case of the hicas sensors not being aligned properly..

Thanks for taking the time to read this, as i'm a :newbie:

No they dont have a boost cut, sounds like its either being fuel starved or a coil has packed up. They do tend to run 11 or 12 with cat back and intake, mine ran 11. 11 or 12 on standard turbo is no drama for the car.

Try testing the coils first, maybe get the injectors cleaned and change the fuel filter. As for the HICAS check the power steer fluid, it runs hydraulicly and if its low on fluid dosent function correctly.

IF you do a search youll find alot more info on these, you might find more R32 RB20DET info on www.skylinesdownunder.com check bothout.

as for hicas light: check your power steering fluid level, if its not low then its most probably your steering wheel that's turning on the light on the dash - either way i wouldnt worry too much about it

congrats on the new buy also!

Thanks for the replys so far, all...

I've checked the power steering fluid and it seems fine, so i guess it must just be the steering wheel (will check the codes for both ECU and HICAS on the weekend)

Will go and check my coils now and let you know how i go :D

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      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
