hi all, just a quick one here. i have searched but to no avail.

basically i have done a few upgrades and have set everything up this is the last little bit before i can get it tuned :)

i am running on my r32 rb25;

-top mounted externally gated manifold

-garrett gt3082r

-Tial 38mm external gate

-greddy profec b spec ebc thingo

im unsure of how to setup the boost lines from the ext gate to the boost controller.

with my old internally gated turbo i only had the two lines going from the compressor side of turbo to the actuator and having the greddy boost solenoid in that line, now we have introduced external gate i am confuzzled.

i did get a fairly vague diagram with my tial gate but it makes no sence to me, i think that diagram excludes the ebc.

what im after is a basic diagram of how this should be setup.

i will have some pics up shortly

a response tonight would be good as i'd like to get these lines sorted and done in the morning :)

thankyou in advance for any info

ben.

above is the tial 38mm gate, see how it has the two banjo type fittings there... i dont kno where these go.

and also on the greddy solenoid there are three outlets which can be used, which look kinda like this;

-NO

-NO

-COM

which one of these do i now use

Firstly, how much boost are you going to be running?

And are those Tial's internal spring change to alter the pressure setting? Or screw top?

plan on running approx 16psi

the tial gate i have is the "internal sping change" type. the spring currently there i believe is a 1bar rating, which will achieve 16psi, as i was advised when purchasing from a reputable turbo specialist place here in adelaide.

Ye you want the closest spring set possible.

I remember with the turbosmart gate i had the 17psi ended up achieving around 15.5-16psi, so you might see the same

In which case put 17psi in there... if you do that you probably wont need a EBC at all, i didnt with my setup

You need to run a line from the compressor housing (boost source) to the bottom of the wastegate, then, on that line, tee in another line which runs to your "in" feed on the boost control, and on the "out" feed on your controller, another line fron the out, to the top of the gate.

ok, to save you the f**king around later, hook kit up the same way as a internal one.. you have an electronic one?

line from MANIFOLD to boost controler -------> to wastgate lower half. top half of wastegate leave open to air.

hooking up the top half of the gate to the controler is another way but is harder to get a stable boost control without spikes etc etc...

ie: do not follow the "external wategate" hose routing that comes with you boost controler..

awesome got it sorted

what im gonna do is connect it up asif i dont have a boost controller.

ie; from compressor housing nipple to lower half of gate, leaving top half free to atmosphere

this will enable me to run boost levels at the rate of the spring which is a 1bar spring rating.

by doing this it will enable me to drive to my tuner and he can set it up which ever way he wants :domokun:

i did do some more searching this morning and found numerous diagrams on the turbosmart website which were very helpfull. even though i have a tial gate and greddy ebc the diagrams illustrated are generic i'd say.

    • Bloody Skylines, they put you through the bloody wringer! Stick at it! Stunning drag strip BTW! Where is it? Can see part of the name on the slip and probably should just Google it!
    • I mean the other day I had to walk someone through diagnosing why their timing belt was walking off the cam gears. At least one of the issues was a bent tensioner stud. Local mechanics have found runout on the CAS mechanism causing weird failures. I'm also no saint here I've documented some of the things I've had to learn the hard way. Something I discovered recently is that my CA emissions catalytic converters weren't even welded correctly to align the downpipe to the main cat and they tossed the support bracket that goes from the transfer case to the downpipe to support everything there. I spend a lot of time chasing down these decidedly unsexy problems and the net effect is it feels like I never actually get to the original objective (flex fuel, VCAM, oil control, cooling, etc).
    • At times with how you make everything sound, all I imagine Americans doing when they see a gtr is standing there looking at it and bashing it with a gun like how a caveman would with a club and hoping it fixes itself 
    • I think this is just a product of how the US market works for this stuff. Shops are expensive and there's no real way of knowing what kind of results you're going to get, people don't really have the institutional knowledge. I have heard too much at this point to really put faith in anybody "full service" except maybe DSport and they aren't really a full service kind of shop. If you go to the right place I have no doubt they'll get it right for you. Some locals have set it up right but the cost really is nuts and even now they're still fighting issues. And you know I'm a crazy person who thinks things like twin scroll, relatively short low-mount cast headers, PCV recirc to intake, recirculating BOV, right-sized for ~400 whp, MAF load, validating all of that to a standard comparable to OEM test programs, etc are relevant. For what it's worth, multiple local owners at this point have been stuck in a perpetual cycle of blowing a motor -> getting someone to rebuild it -> some missed detail causes the bearings to wipe and spin just outside of break-in mileage or drop valves or some other catastrophe -> cycle repeats. I usually only find out about this because I'm perpetually helping random friends with diagnosing car troubles, Skyline or otherwise. The single turbo stuff if I'm honest is mostly secondary, it just doesn't seem to achieve the numbers in the ~2000-3000 rpm region that I would expect given the results I've seen here or in Motive's videos. I don't really know what we're missing here in the US to be causing this. Lots of people like to emphasize the necessity of finishing the project first and foremost, but I'm not made of money and I can't afford to be trashing a 15k+ USD engine build with any regularity. Or spending my relatively limited garage time these days unable to triangulate problems because too much was changed all at once. Also, even if it isn't a catastrophic failure I would consider spending the cost of single turbo conversion with nothing to show for it to be pretty bad. 
    • The water pump is know to leak as well. So if the coolant is low checking that first as well as hoses.
