If so, do you put it on as is, or use sealer around the holes? And I know the block off for the coolant is made for racing only, but what exactly does that coolant go to? Would it be feasable to leave it blocked on a street car?
thanks,
Jared

As far as I know you need not to do any modifications to it or use anything extra. Reduces temps around 20 degrees. I ordered mine last week and hope I recieve it soon

Okie, when using the Hondata gasket you have 2 options when installing, to block the coolant hole or leave it free flowing like stock into the manifold. If you wanna leave it street then just cut a hole in the gasket that is the same size as hole in the manifold and then slap in on there. If you wanna do the race setup then you have to run coolant lines which basicly is a coolant bypass from the manifold. The street setup will do just fine but if you want the temps to be a little bit lower then do the race. Race is better all around and shouldn't cause a problem even if you dont race very much. The instructions will tell you how to do everything. If I am wrong on anything someone correct me.

yeh i wanna know too. im thinking about this gasket.

these gaskets freakin rock.

Its one thing that they reduce intake temps by blocking heat transfer from the head. Its totally another that they save you time (and possibly money), because they are reusable. If you're putting an intake manifold on, I highly recommend them.

I used one on my old Civic/JRSC setup. No grease around the holes and I did cut out the coolant flow hole.

Worked good for me.

Damn, mine didn't come with instructions, I need to know how to reroute the coolant line out of the head.

i don't think you have to re-route any coolant lines. i installed one and it came with instructions and didn't say anything about coolant lines. i kept the hole blocked too.

If you left the hole blocked, take the heater hose that comes out of the side of
the head and tee that into the thermostat bypass. No overheating problems.
Also make sure you remove all coolant lines to the IACV, throttlebody, and fitv.
Anyplace coolant touched the manifold, remove it.

i'll be turbo w. the jg victorx mani...do you reccommnd this gasket for this application? or is it more beneficial for the extra heat generated with SC applications? i would guess cooler is cooler....

I think I remember seeing a complete write up on this product on C-speeds website. Hop on over there and see what they have to say.
