As stated in the title I was looking for help regarding my De-cat situation

 

Purchased a Japspeed decat for my JDN NA online, came yesterday, took it to the garage to be fitted today,

 

And long story short they couldn't do it.

 

They put it down to there being no holes in the de-cat for the lambda sensors and also the EGR (I think they said not 100% sure) would also cause a right problem and would take quite a while to take out to fit the decat pipes

 

So I Was wondering did anyone else have this problem? or has anyone fitted de-cat pipes themselves and found it easy/hard?

 

 

 

Help would be greatly appriciated, I have a couple of bad pictures below that show the lambda sensors and egr i think

 

 

 

 

sorry like i said, terrible pics :sad:

 

Thanks

I would be very reluctant to decat a car these days as it has now been included in the MoT and even older cars are now included in the testers vehicle list. If the engine has not under gone a mechanical refresh recently the emissions and hydrocarbons could be well over the limit and thus fail the test. This is also going to affect cars fittedwithnon standard kit like larger injectors, larger turbos and ECU chips. Prior to now these cars were classed and tested as 'classics' and emissions not included. This has now changed.

 

Its a lot easier to just re-fit the OEM downpipes for the MOT then once done whip them off...30 mins each way. For this very reason ive taken off my japspeed type decats and fitted standed elbo,s for my 3 hole decats:thumbup1:

Yes Mate thats right. was looking at it earlier not sure if I can get the valve out though. Looks like the heater pipes might be in the way topside and doesnt look like it will clear the bell housing from below !

yes mate you can...ive done it thrice plus one and you would,nt like my hands on your plate with chips. No harm to leave it actually as long as you make sure the vacume pipe is blocked off.

That's seems a bit doom and gloom. My cars a 90 grey import so is tested as a precat there is no reason why a healthy vg30 shouldn't pass a precat test, if it doesn't then we need to be looking at why in the first place, equally larger turbos and injectors shouldn't increase emmissions at idle as per the test.

Thanks znut.

That's weird as I had MOT last friday and No emissions test carried out as it isn't required...... well that is what my tester said...... and he's been testing my cars for 21 years.....

I will ask him about changes tomorrow as I can't find any reference to them......
