depends on how wild the cam is, and if it is a 'wild' one then you would need ITB's to get it running right.
utter load of tripe. Wild cams mean more lift at TDC, more lift means more chance of your pistons hitting the valves, in which case you can pocket the pistons to clear. To get wild cams running right you need to machine the pistons if they are that wild and also run standalone because of the overlap.
if you want big gains turbo is the way to go, more gains for the cost[/quote]
turbo's are great for people with load of money that like to replace major engine components on a weekly basis. Lad off Williams Clio's went bang, Nick Read's was unreliable as f**k, even years down the line once the process was perfected and my mate Adi bought it, the car was still an unreliable albeit fast 'nail'. Yes, turbo's make more power, but they cost the same for the same power as ITB's and blow up... or you can spend 8k+ and get one that's even faster and will blow a hole in your pocket as quick as it will the block.
