Here are the numbers 49378-1335850 105, It is a single flapper, I cant rember which is which. I think my 9.5 is a dual flapper.

 

hmm i dunno, I have heard of the dual flapper 10.5 hotside, but most likey what you have is a 10.5

 

u can get a 10.5 in single or dual flappers..

 

off buschurs website "This larger 10.5cm^2 Turbine housing. Fits all EVO4-EVO8 cars and offers a larger, less restrictive turbine housing made in F5 material. This is the same housing from the 2005 MR with the improved single flapper design that was updated from the 2003,4 models. The factory EVO8 turbine housing is a 9.8cm^2 nozzle size. "

 

yes you have a "MR" single flapper hotside

 

Yeah it says f5 on the side, I just wanted to make sure the right one was getting ported.

 

i just replaced the hotside on my 06 and it has that 10.5 stamped into it.

 

whenever you see 105 thats 10.5...

 

yea my 10.5 is a dual flapper...
