try taking yr exhaust housing off and i bet yr bottom dollar its cracked to buggery
or the pissflap ,sorry pennyflap (if internally gated ) isnt seating right mate

worth checking before you bin the tubby... or even just wack another housing on and try !!

i might just do that mate as i have a old T3 turbo with a 48 on the back of it

My .48 was crap and wouldn't boost above 21psi, was suggested that it was cracked and after inspection their was small cracks but after speaking to CR Turbo's they suggested the penny not seating correctly and i think they were right.

Thanks for you in put well the car was going to go back to martin yesterday with my mates turbo on but when i had a look at my turbo it had 4 big cracks in the rear under the penny and were 2 of the cracks were it had moved the casting so the penny was not sitting down right . so i told martin the car would not be coming as it was clear were the fult was so when i got home from london yesterday i tuck the rear casting of and there was even more cracks inside but as look would have it i had a old T3 turbo so i had a look at the rear of that and it was spot on so off it come all cleaned up and on it went well to say wot a different car it is now im going to do some more testing today as on its first run the boost went of the clock which is 30psi on the gauge we think it hit abot 34psi so today it will be coming down to about 28psi . i will all so be giving martin a ring in the week to see when we car get the car back on the rollers for a power run its looking good now all so sins the turbo went back on it is now spinning round when the car is on tick over so im happy

and the reason why it cracked was running to much boost pressure for a small housing - time for an upgrade?

t4 and greys

iTrader: (5)

show me any housing thats been used that doesnt have cracks !!

and personally i wouldnt ditch the .48 either ....... well only maybe for a shady wrc .55 jobby maybe ..

how many do you want to see pal ?

running high boost in small housings is great for punch, but your turbo then becomes a consumable item.

time to drag up an old thread.

my car doesnt make a lot of boost,
its spiking at 1.4/5 and dropping to 1.1/2bar
this is a fairly new T34.63 with a genuine garrett-34 actuator, 1/2 a hole of preload, but no hose connected to the actuator.
even if i bolt the wastegate shut it still doesnt make any more boost.

so i took the air filter hose off today,
with the engine running i can very easily stop the wheel from spinning, can spin it backwards a turn or 2, then when i let go it takes a while for it to catch up and spin the correct way again.
but if i rev it up to 1500 it spins quickly and i recon i could stop it, i can easily slow it down, but didnt wanna do a load of damage.

im about to take the turbo off, to have a look at the rear housing,
but when i had it off over xmas i had a look and couldnt see any cracks on it.

does it sound like the housings knackered? or wastegate not sealing properly?
or should you be able to stop the wheel at idle?

cheers

stu21t

right ive taken the downpipe off and cant find any cracks in the exhaust housing, the wastegate is sealed properly, with the actuator connected i cant move the flap at all.

so should i be able to stop the compressor wheel from moving with the car at idle?
and if i shouldnt, then why can i if there doesnt seem to be anything wrong with the exhaust housing?
lol

my old one looked like it was sealing properly so i put a thin layer of paint around the edge of the penny where it would make contact with the housing then held it shut with the actuator and when opened you could see only half the paint had touched on the housing..
went back to turbo technics and they fixed it with an inconnel arm.. maybe worth a look..

stu21t

bloody good idea m8
im gunna give that a go now, ive got a white touch up stick.

Jay,

agreed mark never seen the point in over spooling a turbo to this degree and add the fact that a t3 has run out of efficiency way before 28 psi

stu21t

you fucking star.
just put some white touch up paint on the penny, and with the actuator connected its only touching about 20% around the housing.

so off it goes to be repaired.
any idea how much?

mine was done on waranty but im sure it said £110 for the inconnel arm on my .63 housing.. i was told it shouldnt bend so easily with that.. was at turbo technics i had it done probably 2 years ago....
