change the exost pipe and boxes to 3" with no cat... and remap again... think you will bee surpriced....!!

stock 1z/ahu won't make more then a real 120-125hp imo. Turbo can't do anything more.

Stock 1Z can do more that 120hp and original turbo. I have a costumer with 148hp with original turbo at 1.3bar of boost. Run with nozzles of 0.232mm. PP502.

Problem is not turbo but yes nozzles.

Can anyone convert this into terms I can relate to? I'm not clued up on nozzle size, or chip part numbers. My larger injectors are from the a4 110bhp, afn?

I am sure the 1z nozzles are 0.185, afn are 0.205, AEL are 0.216. The 0.232 are aftermarket nozzles from bosio pp502.

Think that's correct anyway.

I am still trying to get to grips with nozzles.

[Nuno Cristiano]

AEL use same nozzles that 2.5TDI V6 150ps 0.216mm. Fratelli Bosio have same size with name PowerPlus520 ( PP520 ).

To nice upgrade will go to Race520 ( 0.260mm ) and bigger turbo ...

Contacted s2central but had no reply, surely theres other reputable companies still doing remaps for the 1z? It's not that old! De-cat ing is something that's definitely going to get done, would a 3 inch pipe front to back not be very loud?

[K7ERG]

I have 3" turbo back with one large back box. I wouldn't say it loud. Can hear stereo..........lol not like my old usr4 basically the same exhaust at 80 no point having a stereo.

But I do miss the 5cyl sound track, flames and power. Suppose I still have a 5cyl sound track just more tractor like........

5cyl and 6cyl diesels can sound very well at low revs. we have the new bi tdi's at work, when put into dynamic setting they sound fantastic. beautiful growl.
