Cap for Koyo radiator?

[Ken]

Well, the stock 1JZ cap doesn't fit the Koyo radiator, but the 7M cap fits perfect. Thing is, the 7M cap is a 13lb vs the 1J's 16.

Would it be ok to run the 7M cap, or will I run into any cooling issues?

Stantz caps. Go to Pepboys, they are like $5 or something like that.

cool stuff, the stant 11233 fits and is a 16lb in case anyone else needs one.

I just used a 7M cap...of course that was when I HAD a 7M...maybe I need to start thinking about getting another cap huh?!? That's cool...you figure $5,000 plus already spent...what's another $10-$12 for a radiator cap. Cheap insurance.
