Top Mount Turbo Install And Now Have No Boost

[Shmee33]

Hey guys,

I've recently installed a top mount turbo kit I purchased off eBay a while ago (2nd hand).

Since I've installed the kit I have no boost, it's an oil feed only turbo with a 46mm external wastegate, I've plugged the water lines up and doesn't leak.

I've put the manual boost controller between the turbo and side nipple on the wastegate.

I have the fitting on the top of the wastegate venting to atmosphere and just plugged up the vacuum port that goes to inlet manifold.

I've unplugged the boost solinoid and taken it out (plug just sitting there)

I was set to believe the setup was running 19 psi, I have the stock ecu in at the moment till I can get the apexi. Wastegate spring too high?

The boost gauge is not boosting past 0

Beside all that I have touched anything else

Any help would be good.

Wastegate is stuck open or the turbo is not spinning. Or you have hooked up your boost gauge to the wrong spot.....just possibly.

Car is drivable and blow off valve is working, feels like I'm driving a non turbo car, it's not shuttering or dropping off when accelerating

So you pressure tested intercooler pipework?

What turbo is it?

Sounds bad. ...

[Shmee33]

I haven't tested the piping on the inter cooler but will tonight, it's a t3/t4 eBay ones.

I would be able to feel it/hear it if it was the inter cooler piping???

[Blackkers]

check the wastegate actuator with a compressor maybe.

is the IC piping installed properly?

also what happens when you rev the shit out of it? still no boost?

[Ben C34]

Leave negative feedback!

[Shmee33]

It's got nothing. I gave it a boot full and still no turbo, I checked the intercooler piping 2wice before starting up

Could it be the standard solenoid as I have just unplugged it?

Also because the wastegate is set to 19psi?

When I give it a good revving and back it off the wastegate isn't doing anything.

[Ben C34]

Nope. Sounds like the turbo is dead. Or wastegate somehow stuck open.

[Dose Pipe Sutututu]

Or sounds like it's an EBay turbo that wasn't designed to spool

[Shmee33]

I'll take the wastegate off tonight and have a look.

Thanks for the help guys.

Turbo kit described "good working order" ?

[Blackkers]

bummer

[Shmee33]

That's the wastegate, struggle to get it off but I will have it off tommorow

Well, it would have to be opened a fair way to not allow any boost so I don't think it's your problem. Is it vented to atmosphere? If it is it is (!) heaps obvious if it is open a little or a lot. (Most if it and is in sentence!)

In this order are my guesses.

Dead or dud turbo

Boost leak.

Saw a good vid on the tube, had a cheap external vent wastegate that was opening at idle so having said that, if yours is plumb back it would be hard to actually hear. Could explain alot
