External Vs Internal wastegate
 

what are the pros and cons of each.

Re: External Vs Internal wastegate
 

internal cant flow as much.. thats about it I guess..

Re: External Vs Internal wastegate
 

internal sucks. external is harder to install.

Re: External Vs Internal wastegate
 

pros external: get to run a bigger dp more easily since all you do is weld to the block off flange as opposed to trying to figure something out for the cast iron wg housing. external not as likely to spike, more adjustability (springs are interchangeable), will hold more boost over all without leaking.

cons external: obviously not the cheapest route, have to have a manifold that accepts the wg, have to run a dump tube (well, if you don't want your engine bay covered in soot and risk melting wires/hoses/etc.).

i think the pro's outweight the cons ;)

Re: External Vs Internal wastegate

Re: External Vs Internal wastegate
 

is there a way to convert from internal into external?

Re: External Vs Internal wastegate
 

yea, block off the internal passage, and install a external gate.
