Hey guys i just installed my intercooler about a week ago, ever since then my boost has been playing up, i have a 2 stage turbosmart boost controller ive turned both the settings to stock and in preety much every gear i get boost spike and heavy boost creep!, if i flat stick it in say second gear i get heavy boost creep the turbo and engine sound like there gona blow so i change gears and then the funny thing is the boost struggles to come on for about 2 to 3 minutes it seems like the computer recognizes the massive boost creep after it happens and restricts it for a short while, u guys have any ideas what it could be!

What does the boost creep til? If it goes past 13 psi then yeah I guess that hesitation your getting is rich and retard, do you have the stock ecu?

yeah goes to around 14 psi actually then hesitates for a while, yeah stock ecu!

Hey mate,

I had a similar problem with one of my other cars with the same boost controller as you. Try taking the spring and ball out of your boost controller t piece and reset your ecu and try then. I'm pretty sure it's the boost controller causing all the problems and then causing your ecu to go into some sort of limp mode, it's worth a shot it solved my problem.

Poor installation - go see a professional.

Also, those turbosmart items, well known for not controlling boost at all well.

I personally would sell it and buy a nice cheap $30 turbotech one.

Yes, you are right about this controller having issues, but if you remove the spring and ball out of it, it then acts like a normal t piece bleed valve with a high and low boost setting.

It even says in the instructions to remove it if boost issues occur, it's there to bring the boost on quicker or some crap like that.

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.

      I assume clearances were all a-okay?
