Well, tried to be productive and cleaned up, and out of curiosity I did a compression test today:
Results were (from the radiator back...should be labeling the cylinder #s)
1. 165
2. 170
3. 170
4. 170-175 ish.
Not the best, but it is a 90 w/ 139k miles on it. At least they are close together.
And...found a leak right next to the radiator cap, nothing major but def means I need a new radiator. About a 1/8th long tiny crack is forming...so a new radiator very soon.
So...should I just find a cheap radiator or go with an alum. godspeed or w/e and do a coolant reroute and stuff since I'm going to be in there anyway? I don't have a lot to spend, but I want to try to get something decent once boosted that I wont have to completely redo.

I replaced mine with the Mishimoto on group buy...nice rad...there was also a cheaper one posted up that I looked at and it looks just like the Mishimoto one I bought. There was a post of it not long ago-was on ebay.
Do you plan to drive your car really hard? If its primarily a daily driver i wouldn't really recommend an aluminum rad if you can just find a cheep oem one. But if your going to be forking out 150 for a radiator anyways you might as well go big. If you can do a cheap DIY re route then go for it.
Thank you for re-arranging the results, much easier to read.
I have the GodSpeed in mine, it works fine (even w/o a re-route, yet), I only have one 12" Ebay fan on it, AND Jerry from DIYautotune commented during tuning that my car managed heat very well.
PS - AND the rad has a 22x9x3 FMIC blocking its access to fresh air, AND I don't have the undertray on or any shrouding at all...

Where did you buy yours from?
And yes, I beat the ever living **** out of the car, even though it is a DD.
Do those compression number seem decent? I'm pretty sure I've got an exhaust valve or two that hates life.
