What is the pros and cons of the EGR and a PVC delete kit? Should I invest in this or not? We were all taking cars earlier and one of the guys asked did I do the delete kits? He wasn't clear on the benefits. I've seen them sold but truly never investigated the benefits in the Z32

 

Thanks

Check your local laws, you might cause yourself headaches removing one, the other or both. Both are fitted for emissions control.

 

Why remove either? Well the simple answer is to reduce clutter and reduce the risk of failure. It can't fail if it's not on the car. Binning the EGR does make maintainence easier. Removing your PCVs should stop your engine burning oil during the combustion process lowering the octane rating.

 

However, I found as have others that removal of the PCV system which reduces the engines capacity to scavenge blow by gasses actually leaves the engine worse off. This is particularly pronounced in high mileage TT engines where blow by gasses stop the turbos from draining properly and the engine begins to smoke.

 

There are other deletes that are worth doing though, AIV, PVCR, CC to name a few. Best to research what you want to remove. I've removed everything really aside from the PCV, which I reinstated.
