I'm sure it's in the Borgeson thread and others please confirm what I'm saying, but to the OP, if you go the Borgeson route, please consider addressing the power steering pump. I'm pretty sure I've read in the early Borgeson box installs that the box overworks the power steering pump with too much pressure buildup and there is some sort of PS Pump mod required to address this. There won't be a leak on the 1st day or first week, but I've read one account of the pump housing/fitting leaking about 8 months after install (don't know how many miles driven). Ask Borgeson about it and they may sell the mod, not sure.
I'm curiously watching this thread to hear about the post-install impressions of the OP and would like to know yours as well in terms of steering effort/feel comparison. I've never driven a car with a Borgeson box, but I've heard some say the feel is heavier than the FF stage 2 power steering, but slightly less than rack and pinion. What's your impression? Maybe we should rank these on a 1-10 scale with 1 being the least steering effort with most assist (i.e. stock mopar power steering) and 10 being the highest steering effort with least assist (manual steering).
Here's my intial stab at a ranked estimation list (1=loosest feel w/greatest power assist):
1: Stock Mopar PS
2: Stock Mopar police package PS (cop feel, equivalent to Firm Feel Stage 1 mod)
3: Stock Mopar PS with added restriction washers at PS Pump (could be about the same as 2 above, not sure)
4: Firm Feel Stage 2 mod
5: Firm Feel Stage 3 mod
6: Firm Feel Stage 2 mod + Fast Ratio longer Pitman/Idler arms (I had this on my car and it was just a bit less effort than rack and pinion. I've since removed the fast ratio arms because the feel was a bit too tight and on off-ramps sometimes it felt twitchy if you put in a little too much steering input. Without the fast ratio arms the steering effort decreased by 50%. It was dramatic. In retrospect, I think I'd prefer FF Stage 1 with the fast ratio arms. My FF stage 2 alone feels great, but like Kern said, these stock boxes no matter how firmed up we make them, always suffer from a dead off-center spot from about the 11:30-12:30 position). That would be my one reason to eventually switch to the Borgeson.
7: Borgeson box
8: Rack and Pinion
9: Manual Steering
Those who have driven the Borgeson box, is my ranking shown for the Borgeson correct? Please re-order these as appropriate if you disagree. My intent is to not only educate myself, but also to set accurate expectations for the OP.
