I am looking to maximize the power from my 03 Evo, would this and possibly a SS Tubular manifold offer me some more power or would it be a waste considering the cost.


I can get a 10.5 Housing for about $250 with studs.


No idea how much to install it.

 

Yes absolutely, 10.5 hotside alone can give 20hp.

 

Really? SO I make 347WHP on pump in my Evo, so I can expect 360+ with the addition of this mod AND Dyno tuning?


What about those SS DNP style manifolds?


Thanks, looking for back to back dyno numbers if possible, tuner testimonies would be great.

 

Its a great mod, you will feel it, especially if you tune for it.

 

most people say it takes a lot of work to get it to work properly. does this mean it requires fabrication or cutting? i mean thats a pain not just taking the Dp off etc. right? i wish there was a tutorial for this...er... is there? i will go check. but 1+ on the question about power.

 

20 hp really?

 

It make nice "top end DYNO power"

 

I"m questioning that myself.

Slower spool though. I say put that $250 into a TME turbo

 

You should not have to fabricate anything for a 10.5 hotside install. It should just replace our 9.8 outlet.

 

Yes especially with the mods you have, get the hotside and tuning, you will love it.

 

Yes but it costs $250 and then you need gaskets and then install it, is it owrth the trouble?


Also what about those SS Manifolds?

 

I agree - The only thing I felt was slower spool

 

just bought a megan equal length mani and a megan o2 housing , didnt put it in yet but i cant wait to. with a retun i am hoping to get 15 hp from both

 

Manifolds don't really do mutch power wise on the stock turbo. Maybe 5-15 whp

 

well 15WHP is a worthy mod. I am hoping to add the 10.5 housing and a SS manifold and a Bigger FMIC and larger injectors and THEN dyno tune. I am wondering if I will notice any difference?
