Inside My Turbo

[Mark Dj]

I took my Pre Cat off just before and I thought I would take some pictures of my Turbo below. After looking at the Pre Cat I can see how restrictive it is, :wave: and hello Pre Cat De Cat Pipe on Monday I hope 8) . Do things look ok inside my Turbo? Not sure what to look for lol

looks ok, no signs of oil

 

[MikeS]

look for cracks and that it spins freely

also the oil seals

how many lambdas has the turbo got ?

am i right in thinking 3 ?

 

[Mark Dj]

It's only got the 2 Lambdas Mike, one on my Pre Cat pipe I removed and one on the main cat. It all looks dry up inside, I will check the wheel to see if it spins well. I was happy with how easy it was to remove. I hope it's the same to fit back up

 

[MikeS]

i am wondering about the pre cat

could it actually lean the mixture by the flow of gas at high revs when removing the pre cat in terms of the lambda sensor

 

[vocky]

usually the ecu adjusts ok, but ideally a remap is best

 

[MikeS]

cos i been doing a bit of detective work with my laptop when driving and i know the averages of the front lambda leans out at high revs

a lot more so since fitting the 2.5 downpipe

i doubt a new lambda would sort this

the turbo looks fine but not big enough as our ones at work i can fit my hand in side and finger between the blades lol

My new pipe came today, it looks a good quality pipe . I can't wait to fit it, just waiting on two new gaskets at Vauxhall for it.

 

[MikeS]

remember to give the lambda a good shot of carb cleaner

if you struggle to take the lambda out if u aint got the right tool then put a plumbers wrench on it and use a hammer on the other end, the vibration alone will loosen it up, god knows how hot your pre cat gets

It came straight off mate, it's only a few months old . The old one was broke and old
