Thanks for the Info.
Think i will use Sweenys method...ATM...it does sit very flat..so im not even sure if that would be required Ive already got a stainless gasket for the Turbo. just none between the Adapter and manifold.
To quote you:
With the overall size of the adapter you'll need minimal clearance for expansion to allow the parts to move relative to each other.
..im not sure if i understand? Are you just reffering to when the adapter plate heats up and expands that it could cause a leak..as both the manifold and adaptor will move seprately??
To use a T3 turbo on a T4 manifold.
Ive been wondering this for a while. Speaking to some turbo shops down here....they dont see it that way...as simple T3-T4 mounts.
They just refer to it as Small mount and Large mount..... Basically they are of the opinion that you can have a T3 with the large t4 mount...it dosnt matter...or a T3 mount with the 2 chamber port (like T4.)
One guy was saying he has never ever seen a Manifold with such a bizarre pattern as mine with the single port but large mount? has not even seen an Exhaust housing with such a pattern.
not saying your wrong..cause your way is easy to describe it i beleive. Just very strange and confusing when looking for a turbo. here.
I couldnt get my head around it for a while throwing myself in the deep end looking for a turbo with no clue about turbos.
I wish I knew the answer to your question though, sorry...
