H22a in Civic hatch, Radiator Question

By bk_civiceg
- Mon Apr 18, 2011 5:42 am #250906 I've been gathering up my parts for an H22a build in my white hatch this summer and I'm wondering if the little stock radiator will be enough for the H22a. Has anyone had problems with their H22 overheating because of this? Also, I am going to try to make my own H2d adapter plate because I have access to a machine shop and I'm rather proficient on the mill, but what needs to be done with the flywheel situation? I think the D series flywheel is 6 bolt, while the H flywheel is 8 bolt. So which flywheel should I use or do I need to make a little adapter for that? Thanks

your stock rad should work as well.....even though your in a very hot environment (i know since im in it 2) the temperature at which the block sustains is well above what it reachs out in these regions....with me being from the south in the US it get quite as well as the US deserts which i just left a couple of years ago

if you want holler at neuking.com for a new rad if you want to be safer. with a slim fan..

Without it air that should be doing an efficient job of cooling your radiator fluid can be working at half efficiency or less as it just going to pass over the radiator, unlike the fan with the shroud which the fan pull all the air that enters the shroud. This is especially true if you're sitting in traffic when your car relies on the fan to draw air through the radiator.
