Hi guys,

Getting my car tuned late next week, and so far its just ya 33gtst with "basic mods" using a turbosmart single stage boost controller (flick between standard 7 and its meant to be set to 10psi but spikes 50% of the time!) and Im thinking - should I ditch the turbosmart b/c and go back to the normal solonoid to prevent the thing from spiking and causing issues, or as its being tuned (2-3 day tune) will it be alright?

At the moment the car is running like crap and I just cant wait for the tune to stop all these bugs.

But my main concern is boost. is 7psi stock going to be sufficient? Or should I use the turbosmart b/c and just keep it at the one setting?

Or somehow rob a bank and buy an EBC for minimum 500?

Cheers guys,

Chris

You want EBC-- those profec spec B's are 390 to your door step!! look in trader section!!

Otherwise see what the tuner says!! Buy another cheap bleed value and if there any issues with your turbosmart while tuning, ask your tuner to use the new bleed value and see if that works..

If its still spiking, get a ebc..

But see what your tuner says first..

I got my eboost 1 for $550 brand new. U might be able to get one cheaper second hand or off ebay. Its got 3 boost settings which is perfect since my cars main priority is road use, but the 3 preset settings u can jump between at the press of a button makes its easy if u wanna really give it a boot or take it to the drags. I've got mine set at 8 - 10 and 14 psi. I cant see the point of spending the extra money and getting an eboost 2 with the 8 boost settings unless your cars just for drag racing since its got all that extra jazz in there to take care of that kind of stuff.

it will take a week to confirm a purchase and transfer the money, especially with a weekend in between. you are gonna have to get something local champ. perhaps loan a good working bleed valve from someone until your nengun purchase comes in?!

If you aren't running too much boost, it probably is best just replacing your bleeder.

I'm on 12psi and PowerFC.

It fluctuates but i can't tell from the driver seat.

Here's the curve......

why dont you go with the turbotech bleed valve ($22), and set your desired boost using a boost guage. then the tune will be right for your boost setting, and you can use whichever boost controller you want later, just set it at the same boost level.

Dont be rushed into a EBC just because of your tune next week. Get a turbotech for now and worry about your EBC later. EBC's cost quite a bit so you don’t wont to be rushed into a decision solely based on delivery times.

I have a spare turbotech if you wanna borrow it for a month or so as I have recently upgraded to an greddy e-01 so I can pull the chics like Paul Walker. PM me if you wanna borrow it

Hey Chris!

You will not get the benefit of the electronic type!!

Save your money. The $20 one works fine for up to about 12psi or more.

Or even a small orifice piece that you replace your solenoid with will give you steady 10psi (If the right size bypass hole). It's bypasses enough air to maintain 10psi..

Only when you upgrade the turbo consider a more elaborate boost controller.

I already had the Power Fc installed so all that was needed was to get an electronic solenoid hook it up to the standard solenoid plug then attach the signal & actuator hoses.

Then attach a MAP(3bar) sensor to the input on the power fc.

Haltech sell the solenoids for about $120

Then dial in your levels on the hand controller duty cycle & pressure.

& make sure u have the correct cable/loom

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      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.
