I have a SOHC cam right now but i was hearing some things around like if i put a DOHC head on a SOHC block it lowers the compression then i hurd that the SRT-4 turbo bolts right up to it no problems.

is all of this true?

 

yes

 

the turbo will bolt right on, but there is also a hell of alot of toher stuff you will need to do...
the stock exhaust wont bolt onto the turbo though

 

The neon dohc head has larger exhaust ports, which will help with power. Just get a manifold off ebay, or have a local tig weld you a tubular manifold.

 

use the srt cat pipe after the down pipe and it should fit pretty well to the stock exhaust... will have to use a coupler to hook the together though
