Geraus, I fitted my profec B II to my 34 and am currently running 10psi with the stock cooler and just a turbo back exhaust. No problem at all :miner:

The unit is very easy to install, first one ever and the hardest part was routing the tube through to the engine bay! haha

If you want to know anything just ask away and Ill help if I can!

Cheers!

I installed mine ages ago, but since have installed a PFC & had a dyno tune

You could try boosting it a bit but set the limiter to 11PSI

I found that it wouldnt boost that well and to the desired PSI until i had the PFC installed & dyno tuned

Im thinking of doing it over the weekend, still brand new in the box... Just worried because im still kinda confused with the Greddy/Trust solenoide.. it has 3 holes.. im confused wot connects to them.. i mean looking at my stock solienoid it only has 2 pipes connected to it... why does the stock trust/greddy one have 3? or what is the 3rd hole ? do i need to connect it or na?

Thanks guys,

Geraus.

The hole that is not used is there for if you have an external wastegate. In which case one of the holes being used for an internal wastegate type turbo would become spare.....that make any sense??

I found the instruction manual to be pretty good and made things fairly simple to understand.

I have the same problem with my Profec II. Grateful if someone can post their setting. Mine's stuck at 35% gain and can't go any higher in both HI and LO settings. Beginning to wonder if the problem is with my unit until I see your post. I think as soon as the controller sees the preset warning boost, it cuts everything back to 0.5bar. I'll try to play with the settings again tonight.

      This sounds like someone who would have owned an R33 in their past... It's okay, I'm 100% picking up what you're putting down Mark.

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

      By MBS206 · Posted

      Just back on what was raised about jacking off the the tow/tie down point on the front of cars. I've used it plenty. I've also watched it on a car where you could see it move the front end of the car. It was like the front end/whole car being tweaked and twisted a bit. I will say, I struggle to find good jacking points on MOST cars. The ones that have good points, I then normally struggle to find a jack tall enough to make the car change height!   One of my go to points for either the jack, or the axel stands though, is either a suspension pickup point, OR a subframe to chassis major bolting point. I actually think its the subframe on my R33 that has a bit of a bend in it, from being jacked in the middle too. However, it could have been one of my many other cars I've had over the years! Or it could also be the from me jacking it up, and the fact the top of the front radiator support isn't there, so it can allow the front of the car to move and bend etc.

      My apologies. I forgot we were talking about weird beard M series stuff. Had been talking elsewhere with someone about an R33 with similar subject and got confused.

      Nope, I don't like the look of ND RF, or any ND really, I don't like their faces or arses, why, because of their "modern" lines, the NC, whilst "modernish" has a more rounded shape that I like Well, that's how my overly judgemental eyes see it anyway
