i have the bost controller as above and ive noticed that if im fully fanging it (like we're talking fullthrottle top end of 4th and 5th on high boost, the little plastic plugs that come with it to block the one spare hole in the solenoid pop out and it starts overboosting, i even tried siliconing in one of the plugs but now all of em are popped so i cant run high boost until i block this up, no screw came with the kit to block it up which is stupid and the tyhread seems to not be of standard thread types for that size screw, wtf can i do ?

no because when the plug is in i get no overboost, but when the plug pops off i get overboost, because it creates a leak in the solenoid, dunno wtf is wrong with your boost controller then dude coz if u have a leak u should be overboostin

I dont know, mine had always run with no problems without the little plug for the 3rd port.

i dont actually have it connected atm cause i have an adjustable actuator.

hey sorry to post this up so late.But ive had a problem with my boost ever since i got the above boost controller installed and i just found out that the vaccum + pressure lines swapped the wrong way (with the actu8or hose where the preassure should be and vice versa) so i was getting a suck reading where i should have been getting a push reading to the valve unit.HAS THIS HAPPEND TO ANYONE BEFORE AND WHAT DOES IT DO TO THE OVERALL PERFORMANCE OF IT BOOSTING ETC.?????

      Weird compression after rebuild

      By EndZee · Posted

      But if I smoke test 5th cylinder it’s all ok, no leaks  when I try with 2nd it’s leaking exhaust and intake, it doesn’t come from oil dip stick.    so maybe when car was running poorly, rich or sth. Spark plugs were black and covered in charcoal or sth lookalike. could potential contamination make valves not seal properly? is there also a possibility that rb’s don’t have equal performing cooling passages  meaning back of the engine will be hotter than front. Can this cause improper wear if engine was running under load for short time? Or carbon build up could just burnt from 4-6 and is still on 1-3?   I out of my head like really. Timing is as manual crank-exhaust 47, exhaust-intake 38 at this point I thinking about give it a try and make another 500-1000km and check if anything change, if not I will most likely disassemble engine head /or whole engine and send it back to rebuild. It’s killing me

      Yeah. air pressure leakdown test is where I would be headed next here, using one's ears to determine whether it's the valves or bores/rings leaking...

      More likely you didn't bed the rings in correctly and have glazed the bores. Running with misfires on a fresh build is somewhat of a no-no. Surely no-one "smoke tests" the combustion chamber? That's what a leakdown test is for. Smoke testing is, um, a bit of a wank at best, and only really useful for external pipework.

      Attesa pump mount options / ideas? R32 gtr style.

      By GTSBoy · Posted

      Well, obviously that kit is not a relocation kit or anything other than just the original isolators and the like. I would suggest that it should be a matter of just bending up some flat bar to build a mount over the top of some other diff, with the flat bar held to the back of the diff by the rear hat bolts. A little welding, a little thinking about how to secure the front of this structure, maybe some different hoses in case you can't get it in just the right place.
