Turbo Strip Down, RIP

[dean]

Hi Steve

That is exactly what im thinking, i would like to go down the custom stainless exhaust route but i dont want it to be too noisy, although its quieter than my N/A which has a larger diameter pipe. Also the turbo's cat uses a wire mesh as the base for the coating rather than the (in my opinion) less restrictive ceramic honeycomb used in the larger cat of the N/A, maybe the solution is to weld an ofset into the downpipe of a nice new 8v cat to overcome these restrictions in the turbo's exhaust system..................




and if anyone asks im not taking it apart

Here is where the return oil pipe from the turbo enters the block with a pushfit rubber seal


Got this far, but was stopped by dinner, a lack of light and a massive circlip
need some pliers

Hi Dean,

To remove the big circlip on the 2.5 turbo I ground down a cheap set of snipe nosed pliers. The circlip is pretty hefty.

A possibility exhaust wise would be to buy a sports catalyst and have that fabricated into a stainless system. On the C5 (HDi) I broke out the catalyst to see if that was restricting the engine at all. Sure enough it was but then what do you expect putting a very fine honeycomb in a diesel exhasut. The engine revs much freer now. Much more XUD like but with much better torque low down.

Hi Steve

I havent touched it yet but thanks for the tip it does indeed seem to be a very chunky circlip, ive gota put a new rack in the prestige while im on holiday this week and we have just put an offer in on a house so i may have to shelve all my little projects for a good while if all goes well .
