Default Popping after a new turbo fitted

Hi

My 02 sti type uk (standard)was popping as i release the accelerater, it had been doing for 2-3 weeks and had deteriated the performace to a level where a diesel cars were overtaking!

Got the car checked and was told its my turbo needs replacing!

Bought a new turbo had it fitted and is now back to what i expect very quick!


The problem is that the popping had damaged both my cats and is now running without cats and still is popping but louder!

The mechanic says its a possibility i need a remap or the ECU has a fault!

Can any body please shed some light on this please!

Also i have booked it with racing line for a roller road test on the 13/6/08 .

I think you have to have it mapped after fitting a new turbo mate

not if he has replaced like for like, you are doing the right thing with getting it checked over.

the question is, why did the original turbo fail?

is easy to keep replacing parts that fail, but what caused the failiure in the first place.

has the cat broken up and damaged the turbo? You'll need a remap if both cats have been removed from a newage

wheter you have changed like for like, if the cats are gone, then you have almost a full decat exhaust and as such you need a remap.

Unless you get the cats back on.


hope this helps!

Exhaust leak ?

In the manifold/Up-pipe region = low boost + popping on the over-run ?

IMHO

Just got it booked for a remap stage 1 (330bhp) on the 13/5/08. at the moment its output is around 290bhp, what would i get after a complete stainless steel and a remap?

Either get the Cats out or checked!!

My Cat was slowly disintegrating, bits were being sucked into the Blower & eventually screwed the Blades!

Fitted a decatted STI Up Pipe no problems since!!

Good luck.
