Hi Guys,

Think this relates to the “Tutorial / DIY / FAQ”

HOWTO: RB25DET High Boost mode with standard solenoid??? But blocking pipes instead of cutting wires.

I’m very new to this and could be miles off track!!

The car – R34 GTT (S1).

The main mod that I know about is a 3” pipe turbo back. Originally it had no cat, but there’s one there now - not high flow at this stage.

It seems to be running ok, but as I haven't driven may other skylines on the open road, I don't have much to compare it to...

Can you check out there photos and tell me what’s going on? Any + or – this will have, etc…

I'm having trouble uploading pics, but here's the attachments for now;

forgot to add, the standard boost gauge seems to be working.

boosting to approx +.5 or a bit more. I think that's normal for a stock R34 GTT

any ideas???

anyone else have these pipes blocked?

I've tried searching but can't seem to find much on this.

bro

i just used one of those $35 manual boost controllers currently being sold by turbotech. check for sale forums,, they r pretty good - used it to get rid of wastegate creep

anywho,, that seemed to work for me,, sitting on 10psi at the moment,,

didn't have to do much,, just had to block off one hose after installing it,,

i'll be in brisy this weekend if u wana check out my setup,,

btw , urs is a Series II :D

my boost always ran halfway between 0.5 and 1 on the stock gauge (even before i installed the boost controller)- and thats 10 psi (used aftermarket boost guage to check) , i only have 3" turbo back exhaust and k&n panel filter,,

Hey Afro,

thanks for the reply!!

will give you a call/pm to catch up.

still seems strange I have 3 pipes blocked.

I was wondering if it once had an aftermarket boost controller, when removing it they just blocked the pipes.

I've been told a turbo timer was once installed and had been removed before i got it.

search the forum for 'Turbo pressure sensor' and didn't find much.

especially couldn't find anyone blocking them.

still a mystery, unless anyone else has any ideas? ;)

Afro, will talk soon

Cheers

    • Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.
    • That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!
    • Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)
    • You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
