Turbo

After putting my turbo back on it had no play, since its been on for about 50miles it now has loads of in and out play, now it doesn't smoke at all, but it still seems to be lacking in power, it boosts to 16psi no problem and stays there

but could there still be something wrong with it causing it not to be fully perform?



Heres a pic of the blades if you zoom in does it look like the blades are chipped?

It does look like something has had a scrape around it ..... on the blades ..... is it a standard t28 ? When you put it on did you crank the engine over to get the oil up before firing it up ?

That's what I was thinking looks like something might of been dragged through it, yep standard T28, yep always prime the turbo to build oil up before firing it up, it seems ok off the line but, when putting your foot down in say 3rd from 2k it seems sluggish and obviously that's when it's working the turbo making it build up pressure from low down

Not smoking or anything mate ..... what about the actuator ? Maybe playing up or weak . Checked for boost leaks ....

Nope doesn't smoke what so ever, can't find any boost leaks it also holds boost fine

If its holding boost fine im pretty clueless ..... are you saying its slow in making boost paul ?

Lol nope shoots up to 16psi but feels sluggish on full boost, been told I need to check my base timing and go from there

Yeah mate would be a good start you can buy timing lights relativley cheap always a good thing to have for the toolbox i bought mine about 5 years ago and used it twice lol

yes il guarantee you your timings out or being held back by a faulty knock sensor maybe.
have you done a code check?

has a car in this week with exact same thing and when we checked the timing it was running at 8 degrees as opposed to 18-20
reason for this was the crank pulley damper had slipped slightly so although it showed the correct timing on the gun it was actually a false reading

swapped the pulley for a known good one and then we got the true figure of 8 degrees

as for the endfloat in the tubby............don't honestly think that's your problem here

Yep done a fault check nothing shows up ill check the pulley and timing and go from there

Where abouts is the timing marker on the engine the bit that sticks out for the marks on the pulley to line up with cant seem to find mine

Anyone know where the marker is cant seem to see mine anywhere I've put tippex on the 6 dots on the pulley but now can't find anywhere to line them up with

Is there not a little notch on the pulley ... like most cars have ? I dont know i will check see if mine has one when i get home .

Yea there's 6 notches on the pulley but can't find the pointer on the engine to line them dots up with

there should be a pointer sticking out of the timing cover.
use the second mark from the left on the pulley and mark that one only with tipex
set the timing gun to 20 degrees and turn dizzy until the mark aligns with the pointer

Yep found the point or what's left of it it's been snapped off so what do I do now?

Is there enough of it left to maybe tap like a roll pin over the top or something like that .....?

as long as you can see where it is you should be able to line the marks up roughly by eye

Can't see it unless take the ps belt off that's how I found it lol

Ok so disconnected the tps reved to 3500rpm 3 times looked at timing it was about 12 deg, adjusted it to about 18, turned off plugged tps back in, now looking at it with the tps plugged back in should it still read 18 coz its no where near that once running with the tps back in, but once I remove it again it reads 18 is this normal?

Here's a vid the timing with the tps disconnected is about 18
now this vid shows the timing with the tps reconnected I thought it would still read 18 once the tps is re connected
The rattle noise is clutch release bearing before anyone asks lol

I cant view it mate ?

Can you there

Yeah i can view it now ....

All sorted now did the timing and it feels like it should, pulls nice and strong through the rev range,
