call and ask but i beleave they port match/gasketmatch everything. i got my 10.5, manifold, o2 all done and this is how he did it. came out great

 

Sometimes DB does not like to give out his secrets.....I dont blame him.

 

now there is another perfect example as to why a new thread is never a wasted thread. he saw it, you started b/s, i responded, he than had a question...

 

and that question was also asked in the other 72 threads.

just get the parts and put them on. you will see gains but get a tune or flash for optimal gains. also you may want a 10.5 hotside if your evo has a 9.8 on it.

do you have a d/p? cat delete pipe? i dident see your mod list.

 

ok so you got an 05 evo. so no need for a 10.5 hotside. but get it ported while sending out the manifold and o2. you got a tbe in your sig so there for your set to go after a nice tune. yes you will now see some nice gains.

 

Yes

I have an 05 - 8
BR TBE Exhaust w/ Cat
HKS RS Intake
Perrin Front Mount w/ short route piping w/ Greddy RS BOV and Turbo XS MBC
GSC Cams 272ex 272in

 

lol, now that wasn't hard was it?

i bet it was killing you to type that out though... man.. fingers probably hurt!

 

no hopes for a cat delete pipe? that will show you nice gains as well. then add the parts i said and parts you want and you should see some nice gains after a good tune.

 

Yes.



You ask, I answer, easy as that!

Yeah, Buschur recorded about a 15 whp gain with the Ebay O2 housing alone, in his Dyno Thread. The ported manifold and a ported HS should add a bit as well. All told it should be at least a 20 WHP increment, plus some collateral gains, like improved spool-up and reduced back pressure. Go for it!
