B4U help

So, can any of you guys provide me with some links to a few mods Id be wanting to do? I already have my suspension pretty well figured out (thank you for those stickies!). My mod questions here would be the air box, 9c1 power steering cooler, rear disc brake conversion (or axle swap, for the next part...), gearing change, and does the 9c1 have a better steering box (more responsive, quicker ratio, etc.)? I have access to a wrecked 95 Impala SS, all front end damage. I was thinking maybe I could snag that rear end to gain disc's and better gearing...I want this car to be a daily driver that I take to the 1/8mi strip on Friday Fun Nights, and maybe hit an autocross with a time or two. Again, just for fun. Not planning on winning, just want to be able to get out there and raise some eyebrows in a full size!

One thing I swear by with rear discs is with the stealth brake bolt/proportioning valve mod. It keeps the car from nose diving and the rear caliper brackets from seizing. Rear brakes are actually effective.

I did the Swiss cheese air box mod and it seemed to make a difference but not as much as with a k & n cold air intake that comes with the box to help shield it from engine heat. The intake paired with 2 1-2" exhaust with x-pipe sounds great and definately frees up some power.

Yes, I'd snag that SS rear end or just get the disk brake parts off of it,
though that would mean pulling the axle shafts off to get the backing plates.
Remember though, your B4U rear is the wider version similar to the SS, that gives
it that cat-like wider stance, so maybe you can find someone selling just the rear disk brake
backing plates to save some coin and would be a bit less work than swapping the whole rear.
You can buy all the other parts at Autozone or RockAuto (Calipers & Brackets, hoses, & rotors)
Keep in mind, either way, you'll have to run new hard lines on the rear end out to the wheels
which can get messy if you havent bled brakes before.

The rear ratio is only slightly better in the SS with a 3.08:1 ratio to the B4Us 2.93:1.
So not really worth the expense of buying the entire rear in that regard.

Ive bled brakes, but as Ive said before, Im no mechanic. Parts guy, yes, wrench turner...not much lol. So, pulling the whole SS rear end would gain me the disc's, and a 3.08, which is barely better than my 2.93, but would provide me with a LITTLE more umph on the track. What would a sane person pay for a 95 SS rear end? Ill probably need to redo the brakes at the same time, and Id add the metering bolt mod at that time as well. Ive never converted anything from drum to disc brakes, and not that I dont trust my mechanics here, but the two I DO trust to do that are ALWAYS super busy. What about the power steering fluid cooler? As far as I can tell, thats one of the few things a 9c1 has that the B4U does not, and I would want that as well. Is that something I should just pick up from Autozone and have installed? Or do I need to find a 9c1 unit? Is that possible with the stock power steering I have now? And which steering gear box do I need to find for a quicker ratio?

Yes, you can still get the police option PS cooler from Rockauto or maybe even autozone.

Police cars also had stiffer springs and shocks. I'd go with the Monroe Severe Service shocks
which are just as good as the Bilsteins but half the cost.

As for the steering box, the Impala SS also had the quick ratio, so look up that application.

The B4U has the 12:7 steering box same as SS so no need to change that.

Following up on hat Nab mentioned. The 9c1 cooler "return hose" is available from places like Autozome. Got mine either there or advanced auto parts and it's only $5 or $10 more....so why not? Been a while since installing but all you need as far as how and other hardware is listed here and is about the 5th or 6th item down.

On the rear, I had a 2.93 drum in the car originally and installed a stock 3.08 rear with disks from a imp. It was a little better....but, wanted more gearing. Later installed a entire 3.73 rear (that I bought from Nab ) and sold the imp rear. Much happier with that choice and its still going strong.

'95 Caprice SS conversion - Bonny Buckets - 96 Column, Shifter and Console - 3.73 Gear and Herter tune - Z/28 Cluster - Blazer OH Console - Green/Pink bushings - Chromed Impala Wheels - Eibach Springs and Bilstein Shocks - Corvette Engine Dress - the list goes on and still more to do...it never ends.

that link took me to the site, but when i clicked on the power steering cooler link it said the site couldnt be reached....I think Im going to try and pick up that Imp rear though. Gain me the discs, and a little better gearing that will still be decent highway mpg.

coolers

So, Ive noticed that Autozone and others have all new coolers for the tranny fluid, power steering etc. Are these new aftermarket ones "better" than the stock GM ones? Is there a such thing as too cool? I mean, can using HD larger capacity coolers have a negative effect on the vehicle?
