Being a tad cheaper because of the crank and capable of meeting goals of what I want now I decided that the 370 and S480 will work for me.
Now deciding how to route this I need some opinions. I like the forward headers but Im thinking getting down to 2.5" pipe might look bad. I also like the log manifold for the placement of the turbo.
Not sure if I am not searching the right wording but I am not seeing much talk between the 2 types.

 

I'm going to be selling my kit soon

The log kits are proven.

 

Ive already bought the S480 from a member so I just need to decide on which style hot side I want.

 

Forward facing headers or log.
Mainly depends on what look you want for your engine compartment.

 

Forget how it might "look". 2.125" or 2.25" up pipes will help spool the turbo much better than 2.5" or 3" pipes.

 

Thats what i want to run is 2.25"

 

From what ive been seeing reading from alot of different places.
I still need to decide on either forward headers or log manifold.

From the engine i need 2.25" pipe to the turbo and if i can fit it, a 5" down pipe. To the cold side - 3" to Treadstone 1245-28 intercooler and out stepped up to 4" at the TB

 

A 4" DP will be more than adequate and a hell of a lot easier to fit. Even a 3.5" would be just fine. 3.5" cold side will also be more than enough.

 

Good to know. I will add that to my notes

 

I would have only stepped up to 4" close to the TB though also
