Hi installed the Turbotech mcb today on my R34 GTT. works really good. boost spools up quicker. Was a bit of a hassle removing the hoses but all worked out! Heres some pics of how i installed it belo

ive installed the turbosmart tee mbc and it seems to be on 8psi and ive turned it about 10~ notches from 0, is this normal? the hose coming from the recirc to the solenoid is still connected but the lower solenoid hose has a screw jammed into it? is this ok?

my boost gauge reads -24inhg when driving off boost when im not touching the throttle but -20inhg when idle, this normal too?

Not too sure what's going on there as I can't see the MBC...but you don't need to keep the standard solenoid on. You can disconnect it.

Just run the hoses from the intercooler pipe to the MBC input side and then from the output side to the wastegate actuator (gold 'bell' joined to the turbo if you aren't sure).

That should do it, then just slowly wind up the boost until your neck breaks.

Any more probs with it let me know! :cool:

hey guys,

if i install this type of boost controller. Is there anyway of knowing (or judging) the psi with out a boost gauge? I know this might sound stupid but I do not have a boost gauge, and im worried if i just install it with out one i could cause some serious damage.

Just ordered one of these.

I have a speco boost gauge but have never paid any attention to it. So after I install this boost controller do I need to drive the car around and keep an eye on the boost gauge and see how high it goes?

What's a safe level for a r33 gtr stock.

Thanks guys.

i have followed these simple instructions. well done they are very good. My problem is the following. How do you know which way to put the boost controller in. I am using the drift t shaped controller it has one end that is 3 - 4mil wide and the other side is 1 mil wide.

To make it simple which end goes to the waste gate actuator small or big

also does anyone know how many clicks is safe on this sort of boost controller. don't have a boost guage inastalled yet am planning on doing it soon.

ok ive done mine wrong lol . so i understand now what to do the line from the intercooler goes to the boost controller and the other end goes to to gold bell thing..got it. my olny question is what do u do with the

vacume line that goes down and back onto some pipe that hooks onto the inlet pipe that my pod is on.

ok sooo im looking at the pic you jam a bold in the line that went to the top of the solnoid and you connect the intercooler and the waste gate one to the new boost controller...

so what happens in the pic d/c from lower solonoid? so you disconnect that line and pull it out or what??

with my solenoid i have some original looking hoses on them so they look like theyre connected, shove a little screw on the end of em and clamp them up.. just in case you get pulled up by coppers and they see it's still connected..have the hoses run down below.!! ftw

I wanna install the manual boost controller for my r33 S2 with standard turbo but aftermarket FMIC(no hole from the intercooler pipe) as well,one hose connect to the wastegate, and where can another 1 connect to? Anyone know?? Can anyone post some photo on???

Cheers

you already have a boost controller, use the same hoses.

See pics in first post to see factory solenoid which is what you are replacing with the Manual BC.

You might need to post a pic or look around a bit more =)

So I have just put in my MBC.

i have the waste gate actuator point connected to the actuator itself and the intercooler point connect to the intercooler pipe. The recirc line is still connected and the second line blanked off.

i have taken my car out, but is still not boosting above 0.5bar.

even when I crank it right up!!?

what am I doing wrong?

      This sounds like a perfect excuse to install a Haltech R3.

      I do believe from context he is talking about a S0/S1 R33 RB25 with associated ECU and Wiring for that, and a manual gearbox into a R34 N/A Auto. I don't have the knowledge of all the pinouts and such but my gut feeling from doing my own conversion is to use as much of the R33 stuff that you can. The "car" wiring is quite seperate from the "Engine" wiring when all things are considered. The only things to truly consider 99% of the time is the cluster, reverse lights and potentially disabling the 'not in P/N' immobilizer circuit.

      Rusty roof repair

      By GTSBoy · Posted

      A realistic expectattion of how long it has to last also comes down to.... when do you think you will be banned from registering and driving old petrol powered shitters? It's 27 years since that thing was built. It probably rusted out 15 years ago. It was probably repaired and looked OK for another 10. If you do a similarish bodge job now, or perhaps slightly better with some actual rust conversion and glassing, then.... get another 10-15 years out of it, after which you'll only be permitted by the CCP to drive electric cars manufactured in their Shenzen zone anyway.

      Let me assume that the concern over a manual ECU is that the NeoDET that you have was an auto and has an auto ECU. That ECU will not be a problem, but you WILL have to Nistune it. And you would have to Nistune it even if you had a manual ECU, because the turbo ECUs will shit the bed if they do not have all the things that they were told they have to have, to be happy. The big one being the TCS CU, which you won't have in your car. Anyway, with an auto ECU (which I have running my originally auto NeoDET in an R32) Nistune allows you to put in a Stagea image which doesn't panic about the absent TCS, and allows you to override a whle bunch of other annoyances that would otherwise see the check engine light on 100% of the time. Also, you can't wind up the power very far on the stock NeoDET ECUs without Nistune, because the boost sensor gets in the way. Nistune allows you to push that problem much further up the dial. Do you even have the boost sensor with the engine? Without it, you are SOL and will need an aftermarket ECU (or to find a sensor somewhere, god knows where). I can't tell you what the wiring loom differences are in a 34. But what Duncan said above needs to be considered. When you say "loom", does that include the transmission loom? Because you will need to swap out the auto tranny loom for the equivalent manual loom, and get rid of the neutral/park start interlock (basically hot wire it).

      I have had the r3c in for years now, maybe close to 7 years and it has never missed a beat, anyone can drive it. Super easy to drive around town, the hotter it gets does get a little hard but it holds the power easy as
