Title: Cam Swap in 08 Busa?
Post by: 8secbusa on July 31, 2009, 08:22:32 PM
I understand the exhaust cam specs were revised on the 2008 Busa, are there still gains to be had by swapping in an intake cam on the exhaust side?

I am still having people say they have swapped out to the intake cam on exhaust side. They say they tell a difference with it in. Haven't tried with mine yet but thinking about the idea.

Stock 08 int .355"/238  Ex .335"/228

.020 more lift on the 08 intake and 10 more deg of duration, I would say there is some gain to be had....  :thumb:

will the 99 to 07 cams fit the 08 09? the only reason i ask is that i have a larger intake aftermarket cam out of a 05.

Yes they will you will need to put the cam bearing snap ring off your old cam on the gen 1 cam. Also you will need to order you an offset cam pin from brocks to replace the stock straight one.

Also, you need to turn the bearing around.

Could you just put your stock '08-'09 bearing on the aftermarket cam?
