Dont use existing vacium lines, leave them plugged in and disconnect the stock boost controller ( the wire that goes to it ).

Install the unit close to the turbos, pick your vacium from the line that goes to the charcoal canister, then the the line that goes to the turbos and have one side going to the front turbo actuator and the other to the rear . Plug the stock vacium lines that go to the actuators . Then the small ( thin) line going inside the car where your screen is, same with the electrical wires . Hook up the pos (red wire ) to ignition and the other wire ( should be black) to earth . Then all you have to do is read your manual to set it up to the boost you want .

I don't understand what you mean , thats the easiest place to take it from, the vacium line that comes from the intake to the canister .

You can get vacium for the boost controller from anywhere you like ( from the plenum ) . If you install the boost controller in the drivers side the run ( of the lines ) is to long and you will get big boost spike . ( it will work though ) .

where is the positive boost pressure going to come from?

as boost controllers like to have a wastegate line ,boost line and small vacume line....

which one is suppose to be used???

i have a hks evc 3 on my rb26 but i cant get it to run, it just goes fullboost, because i havnt found a boost source to connect it to...................

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
