Even plumbed back in, it has a very distinct chattering sound when you leg go of gas. Perth police are on an absolute war path. When it comes to modified cars. In my GTR I used to get pulled over constantly. One of the reasons I sold it. I think you're thinking of compressor surge aka dose Link to comment Share on other sites More sharing options...

BigMoscow Member 45 Member For: 7y 10m 30d Posted 07/06/16 04:12 AM Author Share Posted 07/06/16 04:12 AM May need to start a new topic. Does anyone know if there are benefits to fitting cams to these engines? I know I am not chasing mega power but are there gains to be had. Better response, more hp. I can't seem to find much info. also, are atomic camshafts a dro in or do they require huge mods to the head to be done first. Link to comment Share on other sites More sharing options...

Some camshafts are drop-in, some are not, but you'll probably want to have a tune done to suit them (will cost more and take more time) if you do go down the pathway of different cams.
