Just bought my first barra

Hey I actually thought of that too but didn't know the consequences, the ecu won't detect any boost right?

 

Is there a possibility of detonation or anything silly likey to happen?

In all honesty mate you to have make a decision. Either take it back to stock which wouldn't be that hard if it doesn't have upgraded injectors or pump and cooler.

Or get it to a tuner who can work with the frankstien set up this car has on it.

Seems like this car was slapped together after a turbo failed and wasn't ever tuned correctly.

There's no cheap bargains with these car's if you find one these always something wrong with them. Most of the time anyway.

Bite the bullet spend a heap of cash on it and mod it which will sort out the problem at the same time.

Or box stock it and just flash tune it.

Thank you for all that mate but you are telling me everything I already know

It's definitely a pickle of a jam ya in with this cheap ute ya bought mate.

Hope it all gets sorted. Because buying lemon really leave a sour taste in ya mouth. Get it to the right tuna and they should be able to get on top of it.

Bite the bullet and drive to our little old back water town and see Jetstar.

The ecu utilises a tmap sensor as well as a boost sensor that are separate so it will be fine. 

 

The solenoid is only used to get it on boost sooner and maintain the commanded boost with the softer stock spring. It is not a sensor.

 

If you run it without the solenoid it will become slightly slower to come on boost. As the 5psi spring is very close to the stock boost map it won't detonate. It's not like you are running an extra 10 to 15 psi so the timing will be fine. 

 

What will happen with this turbo with it's larger compressor is it will run slightly leaner on boost. This should be fine as the stock tune is a bit rich anyway. 

 

Try it and see if it still hits the boost cut. If it does still then it's tuning time or stock turbo time. If it doesn't then it will be fine until you find a stock turbo or get it tuned. Ideally you would get the afr checked on the dyno. You'd only need what they call a power run to check power and afrs. This should cost around the $100 mark. 

 

Remember this is only a temporary measure and although it may not hit the boost cut it is less than ideal. 

 

Although it's been said before the car either needs tuning or the turbo needs replacing.

Your only telling him everything he already knows puff....

GTX gen2 FTW.

Surely there is a few 3540's floating around in wreckers for a reasonable price.

Yep I think we've covered it all. 

 

Now we just wait and see.

OP has been on here for 17 days. Has racked up 30 posts.

Lets hope this isn't another hit and run.

Hopefully he comes back often and updates the thread as to what has happened.

I Hope he makes the right decision.

[Kato1290]

cool cool, ill give it a crack now

[Puffwagon]

Let us know how you get on.

 

I'm hopeful that it'll work well enough to get you out of trouble until you sort out a better solution.
