HELP!!! t25 no boost

[KEV 5 GT]

hi all well was looking forward to the pod 2mo fitted rover t25 after some hard graft but ive got no boost ???? the actuator is only holding on with 1 bolt ant theres a bit of play movment in it would this be why ive got no boost ???

[NRG]

Did you preload the actuator. Take Inlet pipe of to see if it's spinning.

[KEV 5 GT]

how you mean m8 ive not checked to see if its spinning

[Sparkie]

have you blanked off the integral dump valve?

[KEV 5 GT]

yes ive put a blanking plate on

[NRG]

Take pipe off to airfilter to check it's spooling.

Actuator plumbed in correctly?

[KEV 5 GT]

i was pointing at the Actuator myself not 100% how you mean plumbed in proper theres only 1 port on it and i just pulled the pipe off t2 Actuator

[bigdavec1974]

Fair enough :)
Seen all sorts over the years, from no vacuum to one being connected to the breather one way value :)
Turbo seized ?
Major leak ?
Waste gate damaged?
You have no boost or low?

[KEV 5 GT]

seems like no boost dont seem to be spooling sounds like

[bigdavec1974]

Defo tightened the outlet , left mine off a few times:/ = f all va va voom
How loose is the actuator rod? Can u move it out away from the actuator without much effort ?
Does tht bracket move under little load?

[KEV 5 GT]

Yh there is slight movement in the bracket

[KEV 5 GT]

it seemed it was the actuator not set right got boost now bit laggy tho kicks in around 3.5/4 and on tickover abit lumpy couldent get lower than about 16.8 afr on the mixture screw ??
is there anything else i need to sort

[NRG]

I always preload the actuators. Take clip off and hold lever closed wind actuator till it fits on then wind in half the circle hole, pull actuator onto wastegate arm and should be close to set. Adjust if needed watching afr's

[SCHWARTZ]

Sounds like you have an air leak somewhere. Try pressureising the boost circuit.

[KEV 5 GT]

yh ive done that afrs seem well out tho ???

[bigdavec1974]

All the carb seals in place? Lobster , main jet seal,
carb base?

[KEV 5 GT]

afrs was spot on before i put t25 on carb seems to be ok to me got a slight blow on elbow i think would that put afrs out ?

[NRG]

What psi boost you got and have you jetted carb ?

[KEV 5 GT]

i was doing about 10psi think carb is stock

[SCHWARTZ]

Exhaust leaks can put afr's out, by that much I don't know tho

[KEV 5 GT]

dunno m8 was running crisp before turbo change ?

[NRG]

Did you use gaskets kev.

[KEV 5 GT]

i got a gasket on turbo to manifold thats it

[KEV 5 GT]

just drilled 2nd stage jet to a 1.2 and air jet to 0.9 and still got a blow from t25 somewhere and its still running like a bag of s*** it wont tick over enless choke is on ????:cry:

[NRG]

Try a gasket on turbo to elbow

Sounds like possibility of a jet being clogged.
