Nice work Mick!

 

Thank you sir















3.5" dump pipe tacked up today.

 

Getting pumped mate....can't wait to tinker!

 

Love the downpipe.

 

So pretty...

 

Is that what I think it is? A 3.5 DP with AC?
I wonder if there is a of the shelf manifold I can buy not just for BW but a standard t3 or t4 TS which moves the turbo over to the driver side to allow for more clearance to run a 3.5 DP with AC.

 

I'm pretty sure the BW EFR's are standard T3 or T4 flanged..

 

I believe so, and Im curious as well.. I don't have the knowledge/tools to build one myself.

 

Fitment is a real challenge with the EFRs. They are much longer than other turbos, especially the EFR IWG versions. Its unlikely that there are any off-the-shelf universal T4 manifolds for the Evo 8/9 that allow any of the EFR turbos to "drop-in". They are too long, and the B2 frame EFRs are also very large in diameter.

 

True, but if there's room, there will be likely be a manifold made for it.

 

Fullrace offers a wide assortment of manifolds for fitting EFR turbos to the Evo.

 

None of which allows a 3.5 dp nor ac at the same time.

 

Not sure about 3.5" DP fitment, but most of them allow for AC

Anyone running a 8374 or larger, I highly suggest you get a 3.5" downpipe. I just upgraded mine to 3.5" and I gained nearly 400 rpm of spool.

 

That does seem like a lot of gain for minimum effort.
