I just bought one and its showing the inlet outlet to be 1.25" for the civic. The evo is 1.5" right. How does that work out. Also what holds the bottom of the radiator in?

Could you explain why your logging scaled instead of raw?
Coolant temp scaled is the correct formula for 98+ vehicles, pre 98 use the other formula

Got ya. Well in that case temps haven't gotten above 190 with back to back to back to back 3-4 gear pulls on the logs.

I know what you mean about the lower hose, but does it leak is the question. Mine didn't. I used a hose that is the right size for the T-Stat housing. I'm assuming you meant T-Stat housing. The water pump is by the t-belt.

yea i meant the thermo housing. I bought the hose that was recommended part from gates. It was on page 4. With all the rubbing on the lower mount, I am worried it might leak.

If you look at this pic, it is of an eclipse. The lower hose looks like it might be the most suitable option. If you close closely, it looks like it takes a 90* angle which would work a bit better for this setup. If it would still rub the lower trans mount, I am not sure

Excellent work. Just a remark though. I was thinking of installing a half radiator from Buschur Racing as well, just to keep my engine bay as neat and empty as possible. I was advised by them NOT to install the radiator if I was planning to daily drive the car. Now I understand that the weather difference between the USA and Qatar is not even worth mentioning due to the massive difference; however, I've been told that our weather is very similar to the weather in Texas.
I have no idea if their advice is based on certain weather conditions or what exactly, but I decided to stick with their advice because of their professional history.

Its actually even a bit longer, I cut both the oem hoses to fit better. You guys shouldn't have a problem with the 3g hoses, but as stated above, they're a bit bigger than the radiator inlet/outlets. I just clamped the **** out of them

They may be trying to save face in case something did happen, maybe because they don't know how it will perform under intense heat.

Got a pic of your lower hose setup? I myself just used stock evo lower hose and just clamped the crap out of it as well. Thanks

I'm not sure if the g4js and the 4g63 head have the same exact thermostat housings, but I can say for sure that you have enough hose to reach either.

There's still more slack I could cut out if need be.
