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.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
