when i got my car and looked under the hood, i realized its not the same as most cars. my intercooler shroud had different things on it- mine is the rotary TURBO with intercooler shroud. everyone has told me this is the JDM stuff. the motor was swapped recently so im sure that its the whole JDM motor. anyways- back to my question, people keep tellin me that the intercooler is bigger for the JDM motor. does anyone know exactly how much bigger? or umm.. how many coolin fins are in the USDM intercooler and what are its dimensions? well, i guess thats enough mind boggling for now. im off to bed.

i'm sure they are the same size, why would they be different? pics?

I'm pretty sure they are the same. Just different writing.

JDM Says Rotary Turbo with Intercooler or something like that.



USDM says 13B and stuff..

I don't think J-SPEC/ US had differences internally, but S5 flow better than S4 intercoolers...

I had the chance to put them side by side and the JDM has a bigger in let and outlet. Bigger to the point that you can slide the US one inside the JDM. the actual dimensions of the overall unit were the same.

Yah ur right JDM said rotary turbo with intercooler

USDM said 13B TurboII

...You can go on ebay and find both JDM and USDM intercoolers for the same price.

well, i guess i got the better one huh? i just polished it- it looks kinda nice... https://www.nopistons.com/forums/pub...IR#>/smile.png
