What is the fastest spooling turbo you can put on an evo 8 2003? Is there a big difference between the evo 8 an the evo 9?

 

the one you have now...stock...and if you want faster spool than that then put a 2.3l stroker. and if your looking for the fastest spooling turbo upgrade than yes the 9 will be a decent upgrade from the 8 and the green would be next in line...and i don't mean that they spool faster than what you have now.

 

no turbo! 8 & 9 stock turbos are about as fast as you'll get, with the green right after that.

 

The VIII turbo is the fastest spooling turbo. BUT that doesn't mean that turbo is good. It dies up top.

I wish there was a turbo that spooled like the VIII turbo and the power band stayed up instead of taking a nose dive @ late mid and high RPM when trying to push it.

 

What is the fastest spooling turbo? Stock ones is fast, much less timing during spool increasing just one or two more degrees to peak really seems to help alot, at least in my case. Valve overlap is supposed to help spool (I never tried it, dont have adj sprockets or mivec).

Fast spooling stock turbo cars are a blast to drive but it's short lived making an otherwise slow car, esp VIII's. If I mash the throttle in first most of the time the car will end up pointing the wrong direction afterwards, which is fun. But anywhere at 6000 rpm you want to shift because there is nothing there.

If I had a IX and some money I would decrease overlap where the turbo dies (do they make an adj gear on mivec cam yet?) and try to get a ecu patch to activate a 35 or so shot at 5500 rpm

To assist boost the diverter valve can't leak and the WGA needs to be loaded, also it wont hurt to crank the boost up to about 30 psi, but you will definately need to know what your doing with the tune and about 100 + oct (methanol inj) would be required

 

the fastest stock spooling turbo is the TD 05HRA-16G6mC-10,5T which was as an option for jdm gsr and rs
there are two versions of them ,and the good one(no reliability probs) is that one with the part number ends with 71
300-400 rpms down from stock evo 9 tubby

 

I would venture to say that the 6.5 TME 16g turbo would spool faster than the stockers due to the 35% lighter compressor wheel.

 

TME with the smallest hotside you can get.

Scorke

 

get mivec and 2.3/2.4/etc stroker and a TME as stated. lol

 

can you eloborate more on this sir. I know the stock evo 8 is equipped w/ a 9.8 hotside.

I have seen various websites that advertise the evo 8 TME turbo w/ a 10.5 hotside(speedelement.com) Is this a good all around turbo

 

I'm somewhat of a newb to EvoM, however i have spent countless hours reading post after post. It all depends on your application. Personally, i think the TME is best suited for regulated competition (real road racing and rally) where the upgraded yet stock sized components would be worth it. for a "all-around" DD i would go for a 20G-9LT "EvoGreen" which would be a good upgrade for your 03.

 

According to shops in the UK that sell those turbos, the 71 is an improvement but is not considered reliable with high boost applications and is prone to failure. stick with the stock turbo and get some nice bolt ons. Also try to reduce weight of rotating driveline parts (i.e. wheels, rotors, driveshaft) to improve response.

Evo4 exhaust housing, 9T.



Personally I feel the fastest spooling stock type turbo would be the evo9RS turbo with the evo4 exhaust housing.

 

Depending on what year of the EVO. But the 05's EVO stock turbo is equipped w/ a 10.5 hotside. Anything below that is indeed a 9.8 hotside.
