since people are fitting the sti 8 intercoolers on to thier classic shape imprezas has anyone tried to fit an aftermarket sti7/8 intercooler to the classic or os that too much of a tight squeeze.

a site in the USA has a sale on TXS intercoolers $799 and im tempted to buy one would the aftermarket one be more of a tight squeeze and thus more like to hit the back of the bulk head

 

Link? I thought you'd already done the STi8 i/c?

i have, but im thinking of putting a bigger uprated TMIC on and sell off the sti 8 one

this is the one im thinking of buying

 

Steve, I had something like this on my Sti v3 for a while.
The huge size also carried 2 x the weight of aluminium. If this large TMIC get hot(heat sink from standing in still or slow traffic, it will take ages to cool down to the 'chill' you are expecting. On a long fast road it will chill, but still take longer than a stock TMIC. I sold mine and went to stock again, and went faster on the track using water spray.

Just a thought.

Steve, that is quite small really, can supply bigger top mounts than that if you want

As 911 pointed out, just need to add a nice NOS spray bar to get the most out of it

 

Or consider a cooling fan(s)

Conrad, wot you up to ? Want some plans

Steve that 'uprated' wrx I/C only has the same surface area as a Sti8

 

Andy, what fans do you recommend and how do you switch them?

Andy, if you need it manufacturing then its possible

 

ive got a water spray kit which cools the intercooler down when it detects a rise in ambient temp and duty cycles and no its not an aquamist system, but i have one of those as well

 

Water is ok but NOS is much better.... Night and Day

 

STI TMIC is better for your needs as it may gets hot on traffic faster but due to design with thin core cools down easily compared with any aftermarket huge and thick TM. Tube and fin cores also cool down faster than Bar & Plate even if they advertised as better core design!
I ordered a Spearco B&P TMIC for my WRX04 but as I don't want to change my hood scoop for an STI one I am going to sell it and buy probably a second hand STI TMIC!
It depends where you drive your car and your driving style!
Water spray doesn't add much in cooling an STI TMIC with STI hood scoop, we did some tests and the best result was 2C degrees down, of course with smaller scoops the results will be completely differents!

ive already got an sti 8 scoop fitted to cope for the larger intercooler , and im in the process of getting a proper undertray made that will fit a classic but still have the sti 8 splitter incorperated into the design

 

I dabbed Andy's idea and using fans on my STI8 intercooler on my....STI8 er!

Works very well

Also tapped it into the GEMS using the inlet temperature sensor and the fans come on at a certain temp etc.

NOS Spray Bars are also good

 

Do you have any pics of the fans on the intercooler

 

Can get some. Mounting is crap though going to redo them later

Be the weekend before I can do that no worries!
