If it has the right flange, yes.

Onkar02 · May 9, 2009, 09:53 PM

hmm well how would i figure that out..?

ambystom01 · May 9, 2009, 10:04 PM

Ask Speedcorps.

Neither manifold will fit a Garrett T25. Both a meant for a TD05-16G (or 14b as in the case of the RRM manifold). SpeedCorps may be able to make a custom one for you that utilizes a T25 flange.

^^ya you would have 2 problems.. flange, and does that t25 have an internal wastegate?

u would need to get the flange for the t25 welded on, and also a wastegate added to the manifold.. would cost you a good bit of money to modifiy it.. i would look into a custom manifold, might be better option for you if u want a good tubular manifold..

yea it has an internal wastegate. okay so forget that turbo. hmm i dont want a a typical turbo all these other guys are running. my last resort is the 16g with the 10.5 hotside. i wanna try something where i can run low boost fine but when i get money to upgrade internals i could let all hell break loose without changing turboes you know?

I don't see why your "last resort" would be the 16G turbo. That turbo is perfect for our engines. Good spool with plenty of room to grow. How much HP are some Evos making by maxing out their 16G6 turbos? They take pride in making serious numbers all on the stock turbo. Trust me, there is plenty of power to be made with it.

You don't like proven setups?

ambystom01 · May 11, 2009, 03:02 PM

Especially when the "unique" turbo is worse than the common setup.

Onkar02 · May 11, 2009, 03:52 PM

hmm mabye i will go with the 16g then. how is the t3t4 turbo though? because i was looking at the dyno lancer list and the guy with the most gains is running a t3t4. so idk which one would you guys prefer?

Demon_ni2 · May 11, 2009, 07:34 PM

i love my t3/t4.. but if u plan on trying to go for more hp. u will need to build your motor either way. 16g is mainly common because u can pick them up used for cheap, and alot of parts can be modified to work on our cars for cheap also.

my 60 trim lags enough so i can drive normal and mostly stay out of boost in the city(but i drive kinda hard, so im always in boost). right when i break crossover into boost its all hell breaking loose.. my hp/trq curve just keeps going up and up and really doesnt tapper off like the smaller turbos, mostly because of its slower spool time, but it suits my driving style. upper rpms and higher gears there is a very noticeable difference between my 60trim t3/t4 and a 16g(at the same psi, i pull about a full car in every gear versus my buddies 16g lancer)

i dont exactly have a standard/easy setup, but i love what i have. it cost me 2 arms and a leg to do(i will be going to a bigger turbo setup soon), a 16g setup is very cost effective, but just dont try to run me or anyone else over 200hp..

do what you want, but any turbo other then a 16g or t25 is unique on our cars..(i like bigger, but that suits me, i like highway power and drag setups.. but i still have plenty of power for autocrossing my car also)

Onkar02 · May 12, 2009, 11:14 AM

That was like the answer to all my prayers bro! seems like we drive very simliar in the same areas! ahhaha sweet i think i know what im doing now.

My friend just churned out 381AWHP and 409lb-ft on his stock turbo... all he has done is exhaust, airfilter, boost contoller, and the E85 conversion... We just installed an AMS lower intercooler pipe and an O2 dump last night, will probably be making around 420AWHP on the stock 10.5 16G @ 29psi boost.... its quick
