Hey,

i am planing to upgrade my classic impreza a bit (after i get new gear box since my third was wiped out:S) and i need new TMIC.

Currently i am running stoc version of it and i dont wanna change to FMIC cause i wanna things look stock.

So what are my options besides modifying STI one?

...i would one bigger TMIC for GC8 on e bay but it says to 20 psi.....witch is a little low since i wanna go to 1,4 bar.

Thanks

 

From new age STi will be better option,you can pick up for good money...

.....but fair bit of modification is needed,right?

 

Have look and you will see if its worth

Certainly not the early little slanty as it'll be a case of... "I'm melting! I'm melting!..."



See what I did there?

 

Lol , maybe he meant which intercooler ,what model year/version classic do you have & what power are you running as std sti V5/6 intercooler is ok up to 350 bhp,newage sti unit good for 400+ .

 

i thought it was because you used italics. i can't see the picture btw.

 

Oh yes sorry guys which TMIC was the question.
English aint my first language so....my bad.

I have 99 Euro version of impreza and i plan to run around 330-350 bhp witch SC36 and all other supporting mods.

I was reading around that standard IC ends around 320 but i wanna make sure all goe well since ICs aint so expencive.

 

what is it with you and witches?

 

That was with......my bad it was to early for me

 

I noticed that original STI intercooler aint exactly cheap (for same money or even cheaper i found few upgraded versions on e bay.).....

.....or does some one has one unit lying around

 

How have you come to this conclusion?
Have you actually taken the time to measure air charge temperatures?

 

So i found this options:
STI
and:
upgrade GC8

Which wayto go?

 

mate a word of advice. i wouldn't buy any stuff from ghey bay. go to a reputable subaru master technician and ask his advice. based on how much you have to spend he will give you the best options for your car.

 

How to say,i'm not very big fan of eBay IC,Induction kits,etc.
I have bad experience with these kits.

Thanks for advice.....will go for used STI version

 

The break points as far as I can see:
Ver 1 and 2 cars with slanted intercoolers around 280 bhp.
Ver 3,4,5, and 6 cars by 320 bhp.
WRX New Age around 350 bhp.
STi New Age by 370-380 bhp.
In part it depends what turbo you are using because if you are wringing the neck of the OE turbo or a small turbo you are making more heat than would be the case for a bigger turbo working well within its capability.

Great.Ill go for STI(aiming at 330.340bhp with stock internals) since extra capabilites wont hurt me

 

ive got a sti6 ic for sale.

£80ono with silicone ypipe £70ono without exc del.

 

I have an '06 STI TMIC that was on my classic, complete with DV and pipework to fit classic, you can have it for £180 + Del PM me if interested.

What year and ver are the new age STI?

What about the Japspeed upgrade? http://www.japspeed.co.uk/Subaru-Imp...er/p-23-1-387/

Sorry for the hijack?

 

No i have not ,but the mapper who mapped my cars gave me the information when i enquired about fitting a newage intercooler to my 2000 uk turbo,opposed to the sti V5/6 that i had on std. I kept with the sti unit and the car was mapped to 324 bhp,i do not know what the the air charge temps were ,but after fitting a zerosports splitter the intake temps were reduced and a slight increase in bhp.
Also a lad recently(72 hrs ago) on this site has had car mapped on here and had 340 + bhp on a sti (classic ) intercooler,if only i can find a link to the thread.

 

When the power exceeds what the intercooler is capable of dealing with efficiently it does not stop producing power but it does create a lot of heat. On an STi 3 intercooler I produced 335 bhp. No big deal but what was a big deal was that the ACT guage only had a scale to 69.9C at that time and it was easy to exceed that air charge temperature.
In excess of 69.9C ACT is a bad thing. Trust me.
An STi 8 TMIC with scoop and undertray is clearly a step ahead of an STi5/6 intercooler.
I have done a lot of work on STi 8 eqipped Classics and a few New Age WRX. There is a case for going front mount on the STi 8 TMIC somewhere around 370-380 bhp subject to the turbo in use.(if you want optimal power output/efficiency)
I am sure that with the right turbo and injectors an STi 8 TMIC could be persuaded to hit 500 bhp. Unfortunately the efficiency of that set up will probably be deteriorating from around 370-380 bhp and while I am sure such a performance could be forced I am sure it would be VERY innefficient.
If you are not measuring ACT and pressure drop across the core you are not in a position to know how well the core is working regardless of whether it is TMIC or FMIC. I have indicated above where I believe the break points are. Beyond these power levels an efficient FMIC will show benefits. Less than these power outputs and there is not really a case for an FMIC.
