1jz twin turbo and a boost controller?

[chrisrundell69]

Dude please post pics of your setup during installation and once installed as I will be doing this very shortly and don't want to fuck it up.

What sort of boost controller did you get? I hope it's not a bleed valve? I'm going to try out one of the turbotech ball bearing valve controllers off ebay as they seem to be all the rage at the moment and for less than $40 you can't go wrong!

not a bleed valve its one of the ball bearing turbotech ones and yeah when i get around to putting it in i will post a pic for u

Prolly not necessary if you're too scared that too much boost will cause you to lose control of bowel function.

you are truly a homosexual...

Sounds good, now that I know you have a turbtech as well I will be very interested in hearing how the car drives with this fitted.

I take it this is going into the JZZ20? If so what mods has it already got and how much psi you running now? How much do you want to increase it by?

[chrisrundell69]

yeha mate jzz20, so far got FMIC, BOV, air filter, and bigger dump pipes and thats about it running 11psi at the moment wanna run it at about 12-13psi maybe

just went and check where to install it and i got tubes going everywhere becuase of the bov um looks like the go might be to block off one of the actuators and just use the one. any probleams with that?

[MR 1JZ]

errr yes...one of the wastegates wont open and your turbo will go pop due to overboosting

[chrisrundell69]

thought so, damnnit. guess i'll be running a few more hoses then lol

[boris]

Make sure you keep them as short as possible!

[BigWorm]

I think he meant only use one signal port but hooked up to both actuator ports. I hope?

I'd rather keep them both hooked up, hooking up one won't make things any easier, just hook the 2 wastegate actuator ports up together, then the 2 compressor/signal ports up together, then join the two lines up with the boost controller in between them.

Nothing wrong with it if you have a spare $5000 for a new turbo upgrade once the old one shits itself.

And that is exactly as per the picture on the first page of this thread?

I have also bought one of those turbotech ones, and mr bananaman has one that hes not using if you prefer to buy off a toymodder.

provided your 1J doesnt start missing at anything over .9 BAR...

not speaking from experience or anything

then you drop the plug gap down to 0.7 and try again.

im using a jaycar independent boost controller, looks the biz, does the job too, and looks more complicated than everything else, just so it looks like your pr0*

* only useful for rice factor

[chrisrundell69]

just hooked it up feels little bit better, havnt wound the bolt in yet but will do later and take it for run see if it works

[chris davey]

I had a turbotech on a single turbo 1jz and it spiked badly even at the lowest boost setting. 14psi could equal up to 17psi. Not too good for me? Doesn't come on boost as quick as my hyperboost controller either.
