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.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.

      Neg, the top one is actually for the front. The sizes are 18x10.5 +18 and 18x11 +32.   I measured many times but I'm sure I'll have problems as this is the thread for problems.

      Just one thing; tapping tapered threads is tricky. Taps are always tapered and you would generally run it as far as you can, but with a tapered thread you have to stop much sooner otherwise the wide part of the taper will run in too far and you will have to thread the sensor in too far too as well (possible that it will never make a good seal) BTW nice wide wheels, I guess the top one is for the back!

      Welp, good to know. Will have to wait awhile until steady hands with drills and taps are available. In other news, these just arrived! I will weigh them for posterity. Edit: 11kg each (or 10.9/11.1 depending on what my scale decides over multiple tests, the 18x11 don't seem to weigh noticeably any more than 10.5)
