I saw on Nutz some days ago, an article on exhaust cams being used as inlet cams. When I bought my car, the previous owner had told me that the cams had been changed to high-lift to give an increased performance, but said it was quite juicy under harsh accelaration.

Could this be the conversion he is talking about? I have limited knowledge of engine mods so would appreciate any comments. It certainly does fly, and yes.. it is bloody juicy when driven hard. What signs can I look for if this mod has been done? Previous owner was intending the car to be a track-car but he had not completeed modding it and so part-exchanged it at the garage where I worked.

You could probably tell the difference by looking at the exhaust cam end lobe via the rocker filler....better if you had a standard car of the same Mk on hand to make comparisons with


I wish members would update their location

Easiest way of spotting if you've got a hotter cam.

Does your car idle without stalling.

If the answer is yes and your running the standard ECU i'd bet good money it's not running aftermarket cams.

As Mark says chances are it was a porkie pie - worth a look though!
