I am planning on building a B20/VTEC the right way. I plan on running high compression, bored out a little, and either a GSR tranny with ATS FD 4.929, or ITR/B16A2 tranny with Spoon FD 4.785. My question is would I be safe with the Fluidyne Civic radiator with the high revs, and the high compression. Don't worry I do use 91 octane and sometimes 100. Would you recommend using Redline water wetter also?

 

You would want to use a fluidyn in such a setup to help cool your engine better ...
1- Get the Fluidyne,
2- Buy a Greddy Type S Radiator cap(for supras) - I couldn't use my old mugen cap because it was too small for my teg fluidyne... you have to use a larger one...
3- Mix Water and Water wettter mix for your radiator fluid, If you live where it snows mix in 20% Radiator coolant.

Why? The Fluidyne is all aluminum and has nice welds so it can handle higher pressures when you use and aftermarket radiator cap unlike an old oem radiator which will leak. Just Water and redline water wetter will cool better than mixing 50% coolant, and 50% water.... but, water wetter does not raise the boiling point elevation and freezing point depression as much as Antifreeze so you get around this buy raising the pressure in your coolant system to raise the BP elevation and FP depression.... this is done for obvious reasons.

If you live in a colder location , I would use redline, raise the pressure, and use 20% antifreeze instead ....

The Fluidyne is also thicker so it cools and flows better ...

Have fun
