is it supposed to fit cuz i tried it and it wont turn....

 

im not sure, but, i remember reading that those radiators only work with the supplied cap.

i'm interested in this radiator so, any info would be appreciated from me as well.

 

Aftermarket Rad Caps... Spoon sells Two types Type D and Type F... the D is standard size that Fits Stock Integra Radiators. For These Aftermarket Radiators you will need Type F... I believe the NSX also uses this so keep that in mind when purchasing a MUGEN or Some other brand cap. Those you must order by part number or Actual Vehicle.


^^ I found that on team-integra, it was a review of the mishimoto radiator. So it sounds like you may have bought the wrong one Here is the link if you want to check out the whole thing!
