how can you tell the difference between the t3 and a t34 to look at.

 

External housing, from .48 to .63

 

is that the exshaust housing.

 

Yeah

 

thanks for that mr c looks like the two of them are t34s

 

t34 also come with .48 exhaust housing

 

The T34 has a larger compressor wheel and housing.
The rear housing can vary in size from the .48 which is the same as the T3 to a .55 or .63.

To get an idea of what a T34 looks like, look at a big turbo escort cosworth as they have a T34.63 as standard

 

thanks for the help lads.

 

This is T3 and T34 I think, found it on google

 

thanks for that james
