Having problems building boost

[87LimitedT]

I just recently put a TE60 on my car I know it will have turbo lag especially with a stock rebuilt converter but there’s time were I have it mashed to the floor and it goes nowhere like it cant build any boost at all a every time it shifts it seems to lose boost and slowly builds it back up. Also I know im running to much for pump gas its set at 22-24lbs but when I go to adjust it down some only doing two or three turns it goes all the way down to about 5-7lbs of boost or sometimes nothing at all.

What kinda of boost controller? Still have teh stock y lines and solenoid?
If so are they dry rotted and or the restrictor facing the right way?

Low boost or high boost actuator?

Typically one full turn is 1 psi aof boost.
Adjust the rod to where you need to pull out about a 1/8-3/16 to get it on puck swingarm.

Is the turbine housing wastgate hole ported?

 

[84BuickGNYorkPA]

Probably the puck is not sealing the wastegate hole to allow boost to build, check that the puck is the correct size for the wastegate hole in the new turbo. Some turbo's have bigger wastegate holes then the internal wastegates have. This is when I went to a external wastegate/down pipe arriangement.

Hmm im curious on this since he says the boost will shoot up once he turns it a few times its either high or low. Typically a poor seal will hamper high boost as well as spool.

OP whats up?

I don't see where he says that, or am i just missing something? My understanding is he is not building boost at all or not much at all.

Puck alignment
MBC incorrectly installed - if there is one
Exhaust leak pre turbo
Wastegate plumbing installed backwards.

Not to sure on the wastgate it was said it was a heavy duty wastgate when I got the turbo, so im not sure if its a high or low boost actuator. I have new y lines and the original boost solenoid still hooked up. I don’t believe the hole has been ported or hogged out at all it was new when I got it except for the waist gate.

Illl have to check on that to make sure that it is. How do the external set ups work?

yes when its set at a certain spot I get 22-23lbs of boost but when I go to turn it down some its goes all the way down to 5-7lbs or nothing at all could this mean the wastgate is not made for low boost levels?

do you happen to have pics of the y maybe thats what i have backwards?

If that's the case, then you can rule out the puck not shutting. I misunderstood. Remove boost controller and run it without. If you can go WOT, then there you go.

Im sorry but i dont qute understand what you mean, so do i disconect the waistgate and if i can go wot that means what?

Sorry, what i meant was ( i must have been drinking) Disconnect the Boost controller and see if you get steady boost.

I dont have a boost controller besides the wastgate on there.

Same actuator you had on previous turbo? Or did this actuator come with the TE60?

one i got with the 60

 

[GNRick]

So you have a stock rebuilt converter......hey guys, doesn't he need a higher stall?

 

[porsches4lunch]

I'm inclined to believe that is the issue. Do you have another actuator you can try?

Yeah i know, but i dont think thats why im having this problem.

I just have the stock one off of the stock turbo, could that work?

 

[TurboDave]

You've got some kind of mechanical issues with the wastegate actuator or the puck assembly its self.
You should NEVER be able to achieve boost below what the actuator spring is rated for (15-18# depending on manufaturer).
Even with the actuator hooked directly to the compressor housing fitting with a single piece of hose (Y hose not in the picture) you should never be able to achieve boost lower than the spring rating in the actuator.

 

[vacuum 6]

It's a HD actuator...18 psi.

Remove your stock waste gate bleeder (the solenoid) and run a vacuum line from the actuator to the turbo, that should give you 18 psi. Post back what you find.
