ran red spring - that was my problem.
Red spring is more aggro than the blue one? I can get a forge actuator with blue spring for R1600

red is the stiffiest.

Very important the - the psi marked on the spring packet is cranking pressure. not boost.

thsi is where FRC excelled. They tuned the car for the boost. and she was flying.

What issue? I thought the wastegate actuator was my issue?

Ruan, enough playing now - i have been telling you this for a while now. Go K04 already. Don't drink brandy for a month and you can buy the turbo... rest will follow...

The spring on the wastegate actuator has possibly lost some tention, so I think maybe I should give the nut one full turn? How does one do that and is it advisable?
1. If the wastegate is cracked you wont see it unless you take the dp off. - common weakness of the turbo

i would drive the car for a few days.....seems as though you are leaking on high boost so its not going to piss oil out and leave massive residue. U need a pressure test.

Ive blown a few turbos and not once was the actuator damadged. Actuators dont pack up. and the rods are locked in by two 10bolts and a clip. Cant move....loosing tension...i dont think so

start with the simple things. like dv change - then do a pcv block off - OLD style...both manifolds. and log after every change.

go back to the basics before adding complexity

Come see me we can go threw the checks....

btw.....whats your timing pull like? any codes....

Timing pull is 0 on all 4 cylinders. I fitted a new dv on friday, revision H. Also I have a bsh pcv block off. I have new boost pipes and an s3 cooler with metal tanks, also a metal throttle pipe. The car has 0 coded on vcds as well.

It boosts 1.22bar at peak and holds 0.8bar at redline.

actually they do...diaphragm tears and the return spring can lose tension, had both happen

is your boost fluctuating when you load in high rpm?

wheres your boost needle sittign when you are in neutral?

polony...i was refering to the stock actuator

Ruan, the very fact that the WG duty cycle is 99% means the gate is shut, (keeping boost in until it reaches specified) now since its not making requested boost, the ecu will keep the WG shut, the boost is not being made IMHO because the the area of the exhaust housing just infront of where the ex wheel sits as well as around the WG door has now cracked. You have already ruled out a boost leak, and in my experience this has been the answer to the problem most of the time.

Unfortunately sooner or later you would have to look at replacing it, with an IHI or K03..ideally KO4

Not at all it hits 1.2 at 2800rpm then tapers off to 0.8 at 6500-7000rpm

Pointing towards a leak.

Put the stock piping back and make sure you tightnen the mooor out of your clams....PS: chek your hoses is not crimping......
