Difference between 225 exhaust manifold and 180?
I was reading on the vortex forums about the ATP Eliminators and they were discussing whether the stock 180 exhaust manifold has enough flow for a big turbo like the GT28R. Some think the manifold is too small and restrictive to flow enough air. The consensus was maybe 300whp max with the stock 180 manifold.
So, for 225 owners like myself, is the 225 exhaust manifold bigger than the 180?
TIA

Now if only there was a bigger turbo with mapping and ecu software ready to go!

Re: 45?
Wow...your manifold looks sweet. How much did the porting and polishing cost? I'll have to have that done as well.
As far as software goes, I heard REVO has BT software but only for the 180s. So, do you know of any piggy back systems or standalone engine management for TTs?

check atp for their gt28 that bolts up to stock manifold...>>
PRETTY HOT, imo...
use w/the GIAC software and get the update...
last time i checked, the pricing wasnt available...
but.... they cast the hot side of the turbo on site and bolt it up (for use on stock exhaust manifold)...
only issue is coolant/oil lines....
