Supersprint decat manifold fitting to AEX engine
Posted: Sun Dec 04, 2005 1:50 am
Hi guys i finally got my manifold from italy couple of days ago. Was pain in the arse to fit, but looks nice! Ill post some pics on here soon. 
First thing is if you buy one be aware of the oxygen sensor position as on the OE manifold the sensor is at the top, whereas on the new sport manifold its positioned further down near the cat. This was MAJOR ball ache as the OE sensor wire was far too short for relocation. As far as i know you cant just lengthen the wire either because you change the readings. Sooooooo I had to take the battery out, and the tray under that and then i had access to the loom. I had to manually cut back the insulation in order to redirect the oxygen sensor cable from further back.
Then used tie straps to stop it touching the pipe and melting, and carefully avoiding the gear linkage.
I had the car up on a pair of ramps to make things easy. I managed to get away with original head 2 maniold gasket too, which havent leaked at all. It has a small leak in the middle at the moment but i took it for a drive anyway...
Its lovely!!
The new decat pipe and manifold definitely make a lovely addition to my cold air intake! Acceleration is noticably better, both low down and a little more noticably, high up in the rev range where (i think) the cat is more restrictive.
I think the main restriction in my setup currently is my inlet manifold. Does anyone know of a inlet manifold/ Throttle Body setup which would fit the AEX engine? I dont want to put carbs on, rather keep my MPI setup.
Also, correct me if im wrong, but if the 1.6 polo engines are stroker versions of the 1.4s, then couldnt I use 1.6 VALVES and SEATS on my CURRENT HEAD? I dont see why this would not be possible if the cylinder diameter is the same. Is this what head tuning companies usually do, and more importantly is it possible???
Cheers
