Hi everyone. Im saved up a bit of cash and want to mak the 33 go that little bit harder. I have recently read here that ppl dont advise running more than about 12 psi on the stock turbo (i currently have the boost set to 10) If i wanted to raise boost levels to say 15-16psi is it better just to hiflow the stock turbo as opposed to buying a new one which seems like the much more expensve alternative. How do ppl rate hiflows?

Have you installed an ecu?

With a highflow, you will need an aftermarket ecu, then fuel pump, then injectors to get the full potential.

Buy an ecu first, this unlocks sooooo much hidden potential within the std motor/turbo.

i would definately recommend the hiflow option. good power increase over stock. i got a vg30 single turbo exhaust housing adapted to mine for abit more top end :down: result being 346hp(258kw) at wheels on 15psi. u make up your own mind !!

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

      By Kinkstaah · Posted

      I used to do that (sills with rubber jack block).. ... then I got side skirts, and there's no way for the jack to actually work there, the jack pad itself on the jack is too big. Is the answer to use a... smaller (?) jack? Hmmm.

      I have too much trauma from every skyline I've ever seen having crushed jack points/pinch welds lol.    Yep, works 100%, it's what I use when I'm using the quick jack. Don't know why I can't also bring myself to do the same thing when I'm using a jack. I blame the skyline PTSD.

      The pinchweld is fine, even with a trolley jack, so long as you're not actually pushing on the pinchweld itself. More to the point, we shouldn't talk about lifting or supporting on the pinchweld, we should talk about using the sill "jacking points", which just happen to be adjacent to the pinchweld. I just have dense rubber blocks with grooves in them for each of the chassis stands and the trolley jack, that I use at the sill jacking points if/when I have to lift/support there. They put all the load onto the steel pad of the jacking point and not the pinchweld. As intended.

      Makes sense.  I would do something different if I felt like there was a better option. Generally the only other area I'm happy to jack on is where I want to put the stand. The pinch weld is not an option for me for either the jack or stands, so very limited options overall.  Plus never having had an issue with doing this, has kinda reinforced in my mind that it's fine. I'd do it on any car without a second thought these days lol.

      I know on some cars it's explicitly endorsed in the service manual but a lot of them it isn't which is what gives me pause. I know a lot of cars also have you jack up the car by the radiator core support which is a lot easier to get to than some crazy deep section of the front subframe. I'm just reluctant to find out if any of that is really safe to do if not listed in the service manual. The FK8 has even the R-chassis beat in this regard, the front subframe jack point is almost fully behind the front tires and is surprisingly recessed into the car.
