Outer Limits 4x4 Board

HI everyone,

Fitting a boost guage to my ln 106 lux, but not sure where to fit the t piece in to the whole system.

Ive looked at the guide on toyotasurfasn but theirs look different to mine even though i have a ct20 turbo.

Any guides or pictures of where yours are hooked in would be great.

Ive got everything sorted except this rather important bit.

Thanks

depends what manifold you use. most of the upright manifolds have a stock location for boost comp to connect to. use that location.

if you have stock manifold you may have to tap/weld on one to the inlet pipes somewhere.

On my old Lux I made an adaptor to go on where the rocker cover vent tube used to go onto the intake manifold.

Any chance of a pic?

thanks for the advice

Nah I dont think I have a pic of it.
I sold the Lux about a year ago.
It was simply a couple of inches of hose to slip over the barb on the intake manifold with a brass barb the same size and an olive style nylon fitting screwed into that in the end of the hose.
Sounds complicated but is really simple.

This would measure vacuum, as the rocker vent is normally before the turbo intake!

It is really simple, we need info on where it plugs into the cross pipe or manifold after the turbo.

I said it goes where the rocker vent used to go into the intake manifold before the turbo was fitted. It is a barbed fitting on the intake manifold that gets blanked off when the turbo is fitted and the vent pipe then goes to pre turbo.

The shop that did the injector pump after I put on the turbo tapped a hole on the pipe, one side goes to the boost compensator and the other to the boost guage.

That's OK!

I didn't have all the info first go!

It's a good place in that case!

ON this picture one end goes to the guage, but where does the other end go?

sorry to be such a turbo tech dunce.

ah... just learnt to read, boost compensator. do all set ups have a boost compensator? if so can i just t piece that instead of risking metal into the intake or having to remove bits?

no you wont have a boost compensator unless you got one fitted or your running a surf injector pump. i did the same setup as ausyota, modified the the old breather fitting on the standard intake manifold, very easy with a few clamps, hose and fittings. definalty boost there, my gauge doesnt even go into vac at an idle.

Is this the 10mm (approx) pipe which sits in the center of the top of the manifold? in the picture that was added to this topic it would be just hidden by the left edge of the brass t piece.

ON mine it has been capped off with a rubber cap and a pipe clamp?

If so then it looks like an excellent place to fit it. Is there an easy way to down size the tube that would fit this fitting to the tiny tube of the boost guage?

yeah thats the one, i just used a piece of pipe about 2 inches long clamped it to the original breather fitting on the manifold, put the fitting that came with the gauge on the end of the boost gauge line and push the fitting into the open end of the piece of hose on the manifold and clap it in there. worked for me but it depends what gauge you have you may just have to find a different fitting.

I think that will work for me too.

I will have a go this afternoon.

Thanks for everyone help.

i just got some fittings from pirtek and connected it to where the vent pipe used to connect to the intake just like the photo(dont have a pic of mine so i found this one), and installed the gauges in the dash.

UM, things arent looking to good

for my issues

I fitted the boost guage here is this right?

y start up a new thread?? you have plenty of folks in this one giving advice...

SORRY.

I thought as it was a new question the right thing to do was to open a new thread.

The heading of this thread is no longer relevant to the question involved, as im no longer trying to learn about how to install it.

My new question is is my turbo stuffed.

I didnt mean to snub the people already giving me help hence why i invited their comments on the new question.

I didnt know i was doing the wrong thing - Once again Sorry.

I have re asked the question in this thread so feel free to delete the other thread (though im still not sure why it was an issue, im sorry for my error).

IM concerned that my CT20 turbo on my LN106 HIlux 2.8L 3l Diesel is not working i.e no boost.

I fitted a boost guage this afternoon and its not registering any movement under revs - if anything it is creating a tiny vacume.

The picture below indicates where i fitted the boost guage.

I removed this bung and the boost gauge and gave it a rev, at idle you can feel a pulsing air flowing out (like a mini exhaust would feel) When reved the amount of air comming out reduced but didnt stop completely.

PLEASE TELL ME IM WRONG.

If you cant tell me im wrong advice would be great...

No biggy.
Its still about your turbo and boost gauge and the mod you asked about in this thread.
Like I said, no biggy, but I needed something to do around here

Should be able to change or add on to the name of the thread

Ha ha know the feeling. cheers

Ok so back to topic.

Hooked up the guage again (flea bay purchase - second hand speco boost/vacuume guage) unfortunately it shows a -4 psi reading instead of 0 which confuses things a bit but the change should indicate boost.

On the advice given I went for a drive rather than just revving it in the driveway. Found a big hill and flogged its guts.

On the up side we have boost! on the down side it maxed out at about 5psi at 3000+ revs uphill.

I thought normal for a ct20 was about 9psi.

if 9 is normal... the turbo is working but not well? or do i just need to wind up the boost from standard?

Could the guy who fitted it (home job) have resricted it somwhere by mistake?

thanks again

Oh and being able to edit titles would be a good idea.

Just go to yor first post and click edit, you can edit the thread heading from there. Well I can even if you can`t

indeed so can we.

ta guts

-4psi + 9psi = 5 psi ? Is the gauge not zeroed?

You might need a restrictor in the line to the boost gauge. The one I got from the local vdo dealer at the time was tiny and slotted into the tube going to the gauge.

when the engine is turned off or at idle the guage shows -4 psi or a vacuume of 4psi.

At maximum boost its showing 2psi.

2 - -4 = 6 psi. but thats assuming the guage still has an accurate spring rate. maybe this is the problem.



Sorry but I didnt understand the bit about the in line restrictor? whet do you mean?

6PSI is OK, there is a device called the waste gate, you probably know about, but if you still have a problem. Is it opening early?
