J-Spec Intercooler

[VIN18M]

At the moment I have a turbocharged factory 4G93P in my Satria GTi and have been running a VR4 j-Spec intercooler mostly because it was more than enough for the little 93 and also because it fit the front bar nice and neatly and looked almost factory.

I'm now upgrading to a Evo 0 RS 4G63T engine but would like to still run the J-Spec cooler and potentially upgrade the outlets and plumbing to a larger size. I could go larger with the intercooler however there isn't much point as the air dam is only so big to fit the cooler and I want to steer clear of chinese copy Hybrid coolers that will need the front bar chopped up even more.

At the moment the cooler is easily keeping up with the 10psi i'm running through it and the cold side is always ice cold no matter how hard I've been driving the car.

How much power could I potentially pump through this cooler with the 63T before it's running at the end of it's efficiency range?

i will regurgitate some info from the net,

if you upgrade the end tanks to 2.5" outlets, the cooler will flow enough for 400hp easy.


my personal experience,

i upgraded my Evo Zero (J-Spec VR4) cooler to 2.5" endtanks and had no issues at 18psi with a VR4 engine and a 16G.


there is nothing scientific about the above, if you really want to know for sure, bust out a thermo couple and measure the temperature differential, then also use a spare boost gauge to measure the pressure drop across the core. That is the only way you will get concrete information if the VR4 cooler will be 100% right for your application.

I'm not sure the j-spec cooler will accomodate 2.5" piping? It's not an Evo 0 intercooler (which I believe is the same as Evo 1-3?)

It's just the normal j-spec cooler so I think it's limited i due to the thickness of the end tanks. I was thinking of increasing the outlets to around 2", I think that's the maximum I'll be able to run?

Evo Zero is not the same as E1-3, it is only a slightly taller stock J-Spec VR4 cooler.

i can assure you 2.5" outlets fit perfectly fine.

I stand corrected, thanks for the info, nice looking setup!
