Awesome. thanks Dan

[Cam.]

Pftt. 34 is awesome on the 2.5!!!

Awesome response and will hold boost to redline.

Kido tunes suck balls.

[dja]

34's are baby turbo's, they lack top end power, nothing can change this.

 

Dont bag kido when u have msr tunes, there both business's trying to get customers.

Go a 20G

[Sam]

I am 90% sure I am going to do the following:

Kinugawa TD05 18g - $800

STI Pink Injectors - $310 

3" Stainless Exhaust no mufflers - $300

Tune - $250

Total Cost Approx - $1800 roughly

[alexGT]

20G gives you more top end without sacrificing any mid range. my rex had a 20G and had 18psi by 3000rpm in 4th and pulled to redline.

 

they cost almost exactly the same amount and will save you from needing to upgrade in the future

[aekOne]

the 20g is well suited to the 2.5L also

Interesting. so you guys are saying go a 20G then?

[skillionaire]

Hi,

 

I don't know what gave you that impression, Aek?

 

Cheers,

Nik

[dja]

All above is correct, you will regret the 18g within 6 months, possibly even after first tune.

 

Look into a FMIC also, i will never understand why people insist with TMIC's, science doesnt lie, much like my hips."shakira"

[Sam]

Hahahahaha. Aaarrrrggghhhhhh. 

20g with top mount and bigger injectors.. 200kw?

[alexGT]

yes.

[Sam]

But then if I decide to go front mount for a little more power it is possible. Correct?

fueling/internals/heads (not sure what you have)/headers will be the next limiting factor

[cameron]

i quite like my vf34p20 on the ej255. im not going to race the car and the speed limit on local streets is 50-60kms. for a street driven car i think its fine

[Sam]

Factory EJ257. Not built but bought brand new. 2L heads. 255L walbro. Std headers

I want around the 200-210kw mark. 

[dja]

you will get it.

The front mount just lowers your intake temps significantly, so your able to make power easier, and can get some fat torque curves.

 

Tmic's do it also, just not as well.

 

I put a fmic in my 2.5T gen4, mathematically there is 200ms of lag, but driving it, there is none noticeable at all.

[Cam.]

Oh well, Just putting in my two cents.

Do whatever you gotta do.

[T-REXX]

YOur budget is $2500???

 

IMHO i would save the extra $$$$ even if it takes you 6 mths and do it right the first time.. If you dont youll regret it.

 

Here is what i would do..

 

Blouch 18G XT

ID1000 or 725.. really doesnt matter.

Silcon inlet

Tune

 

Why ID1000s over STI Injectors.. 1, the flow evenly and will give better idoling then sti injectors.. specially on start up. IDs are proven and work.

 

Why Blouch. I would never go a 20G on a EJ257 unless it has Dual AVCs.. itll be not overly responsive. The 18G will spool AS FAST as a VF34, Make 20% more power and come on boost very very hard.

Silicon inlet is a no brainer, pointless doing other mods with out it.. itll choke the turbo.

 

Tune.. Stay away from these internet tunes. They dont know the age of your car, the engines life , EVERY CAR is differnet, so how can they tune a car over the net. They say you can go back and get revisions and keep going back and forth and back and forth till its right... WHY??? do it once and walk away.. never have to worry about it.. AND if for some reason the engine pops, will KIDO warrant the engine due to their stuff ups??? MSR will 100% if its his fault.

 

unless you go a Dom 1.5 or bigger a FMIC is a total waste of time... Zero gain and zero point.. STI TMIC is good for 230-240kw@wheels.. if u want something bigger, PROCESS WEST TMIC

How would lowering your intake temps be zero gain, or a waste?

 

For half the price of a process west you get a cooler that is more efficient then TMIC, and allows for more headroom, and hot aussie weather.

 

Putting the fmic on my gen4 2.5 lowered my intake temps drastically over a tmic, same on my gen1 and 2.

 

You cant argue with proven science.

 

Also, alot of people run the td0520g on non avcs, and single avcs 2.0 and 2.5 engines with good response, and great top end. There is evidence of this on this, and the rest of the subaru forums.

[T-REXX]

FMIC on a car that has a small turbo we have proven that there is no real benefit and the car is not as responsive.

I didnt say its laggy, i said its NOT AS responsive.. and yes you do get good top end..  But it also depends on WHAT 20G your talking about.. are you talking about the Taiwanese Kinguawa, Zage, Kando 20G  (all the same turbo from the same factory in TW) or Blouch 20G or Tomei 20G.. those 3 turbos are so far apart its not funny.

 

Blouch 18G will out perform power, faster responce and more torque then the Kingauwa etc or Tomei 20Gs.. that is proven on all subaru forums.

 

a PROCESS WEST TMIC on a car that doesnt make 230kw or more is not beneficial... and once again proven.. so going a FMIC as much as i may decrease temps it also decreases responsiveness..  Once again proven.

FMIC is not needed for cars under 270kw@wheels.. even then their are cars out there with PW TMIC making 300kw@wheels.

There are cars out there with 250kw@wheels still utilizing Stock TMIC from the STIs.....

Whilst he has a STOCK Engine, with no internal, a FMIC is simply pointless
