I updated this pic to the original post, as it shows the intercooler a little better. It is an ST205 Celica GT-Four Top Mount Air to Water intercooler core, which better explains the filler cap
We have approximately 28 feet of water lines running from back to front and back to-and-from the heat exchanger that is mounted where the A/C Condenser was. Its holding up to a hair over 400hp with consistently cool IATs all the way up to 24psi (as high as I've tested thus far).
Here is an old shot of the heat exchanger:
And another pic with the ET Street radials that isnt photochopped (really old pic):
The gauges were custom made by a company we have an account with. You can almost fully customize your gauges with color, font, lettering etc. If I remember correctly they were less than $175, and are much better quality than what I've seen on eBay.
I must have missed your pictures, but if you point me toward them I can tell you whether or not I agree on which car is nicer
