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.

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. :smile2: 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.

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?

The individual Mod Links within the document don't work. You just have to scroll through it and find the mod you're looking for. Here is the info just in case that I cut n pasted from there along with a couple of pics installed on my car.....


Installing the SEO Power Steering Cooler


Advantages

Keeps the power steering fluid cooler than the just the stock unit, which is a good thing, especially if you autocross you beast.

Disadvantages

Additional hose routing needed, blocks some flow to the radiator.

Parts Required:

  • 1 Pipe Assembly, (GM P/N 26036034), $???
  • 2 Clamp-Lo (GM P/N 2091638), $???
  • 10 pack of bolts, (GM P/N 11509363), $???
  • 2 Nut, RR BP, (GM P/N 12337917), $???
  • 32 oz of GM Power Steering Fluid
Total cost is around $50.

Tools Needed:

  • 10mm wrench
  • 8mm wrench
  • Floor Jack
  • Creeper or something else to lay on underneath the car
Procedure (from Basim Jaber):


  1. Park the car, place blocks at rear tires, and set the parking brake.
  2. Siphon, pump, or drain the power steering fluid from the reservoir.
  3. Detach the reservoir from the bracket (it slides up), and detach the fluid line from the reservoir. This is the one closest to the front of the car. Save all of the protective sheething for reuse later!
  4. Tape up the end of fluid reservoir line to avoid spillage
  5. Jack up car and remove the clips that hold the two power steering lines. Tthey are under the motor along the frame cross member.
  6. Slide the plastic steering shaft cover off of the power steering fitting and unhook the two fittings from the power steering gear. Beware: this is a knucklebuster job! Use an 18mm wrench here, and watch out for draining fluid. Unhook the forward one first.
  7. Remove the power steering line in question that is to be replaced with SEO 7L9 tube assembly.
  8. Insert the tube assembly. The RH side goes under the coolant hose, and the LH side goes underneath (or possibly between, if it will fit) the oil cooler lines. Getting the RH side underneath the coolant hose will be snug, so hang in there.
  9. Hook up the cooler hose line to the reservoir using the stock clamp, and slide the reservoir back onto the bracket.
  10. Install the screws that hold the tube to the radiator frame housing using a 10mm wrench. Tighten them later, after fitting everything else, especially the cooler fitting to the power steering gear.
  11. Install the SEO cooler fitting to the power steering gear and tighten well. Note that if you take off the left wheel, there's more clearance to get a wrench in there from the side.
  12. Slide the plastic shaft cover back over the fitting.
  13. Install the stock inflow line back into the power steering gear and tighten well.
  14. Fill the reservoir with new fluid. Fill until the "C" mark (full cold) on reservoir cap is reached.
  15. With cap off reservoir, turn the wheels lock to lock 40 times.
  16. Lower car to ground, and check that fluid level is still at "C". Add if necessary
  17. Start the car, and turn the wheels lock to lock for two minutes.
  18. Check the fluid again, and add as necessary.
  19. Replace the fluid reservoir cap.
The hardest part of this mod is disconnecting/connecting the fittings to the p/s gear unit. There isn't much hand room and the wrench can only turn about a 1/8th of a turn in either direction. Consult the service manual for the standard precautions and more information on this mod.

Front clip removed....



Installed and you may see the small rebuildable PS filter I spliced in up near the frame....

Those were offered on the 94-96 9C1 cars. There are some individual hoses new for sale up on eBay and a full used set for ridiculous money...$225.

I have a full set already cleaned up that I may let go for $100 + shipping if you're interested. Even after over 20 years these hoses (which are referred to as "lifetime hoses") are still in great shape. Have had mine for over 5 years on the car without issue. They're a GM part and I like the look with my setup.

Any answer to this question here? Just know that some fluids have an optimal operating temp, and I dont know if upgrading the stock coolers with HD ones will drop those temps "too" low or not. Also, does the Street Trends "Ram-Air" hood actually work? So many aftermarket makes claim gains, but fall short. I like the looks of it, and if it actually works well then I will work it into my build budget.

Also, I need a link to the dual electric fan mod. If anyone knows where to find that I would appreciate it! Thanks!

Electronics, yuck...

Yep, above my electrical level of non existent expertise lol. This I will be hiring someone to do. Any answer as to whether or not HD aftermarket replacement coolers will drop the temps too low? I think most of them are thermostat controlled, so that would keep them from working until the fluid gets hot, but Im just not sure. Again, thanks for all the patience and help. Not being very mechanically minded makes this a bear. Right now all Im doing is gathering information and trying to plan the direction of my ensuing build.

OH! Ive been told I need to get a tuner. But, those are quite confusing, and Im wondering if its even worth it. I saw two different styles on JET performance, but Im wondering if the extra 20hp they claim is worth the $500 price tag. Suggestions?
