    Thanks for the suggestion! I'd always heard the opposite, which is why I did it the way I did.
    I don't have a pressure bleeder, but I do have speed bleeders (basically just bleeders with a ball valve that when you loosen them, lets fluid out but not air in) and they work very well on my other cars and also make it a one man job.

      I also always bleed the brakes starting at the rear passenger side and finishing at the front drivers side. I just use the two man method and it works just fine.
      I have a vacuum bleeder but that does nothing, total waste..

        Ended up adding phase 2.5 of the 3 phase project, and pieced together a coilover setup.

        After waiting 2 weeks and never having the coilovers ship from GC, I cancelled my order and decided to wait on the suspension piece. In all honesty, after doing all the bushings front and rear, the suspension was actually feeling quite a bit better. It's still relatively soft and very DD oriented, but it makes driving around very comfortable! Plus, it actually sits really low for H&R OE Sport springs and KYB struts.




        It doesn't sit quite as low in the front, but that's mainly to do with the fact that rear arches are much lower than the fronts, being a late model.


        So this all started when I purchased a parts Ford Probe a few months ago that happened to come with two 7" 375in/lb Eibach springs rolling around in the trunk. It just so happens that's the exact rate that GC had suggested to me when I ordered from them. As mentioned in my previous post, I also happened upon a large lot of loose Eibach springs of different rates and lengths, which included some that were 6" 450in/lb. So now I had the springs, but still needed the sleeves and shocks.

        I researched the shocks for quite some time and ended up purchasing Koni 8641-1144SPORT for the front and 80-2522SPORT for the rear. Last up was the coilover sleeves. Now IE Motorsports sells them, but at $150 for two, I was not too keen to buy from them. Ended up purchasing a random set of four on Amazon for $45. Meh, a sleeve is a sleeve.




        Today I got around to installing the rears. Didn't take pictures of the install, but it was relatively straight forward. Shock swap is obvious and easy. Only real modification I had to make was cutting a good amount off the height of the sleeve, as they were a bit too tall. I cut them right above the "35" line in the picture below... basically in half.


        They rather conveniently came with some small screws that thread into the sleeve to affix it to what would normally be the strut housing. I instead used them to hold on to the rubber pad and nub that the spring normally holds onto (sorry for the blurry pic)




        I ended up installing them with stock rubber pads both top and bottom and with both lock rings, but screwed as low as they would go.


        When I put the car back down on the ground, it sat pretty much exactly where it had with the OE Sports, maybe a tiny bit higher. Of course I can pull one or both of those lock rings out to get almost another inch lower, and can also resort to removing the upper and lower spring pads, or going with a 5 inch spring. For now, I have no issue with the height they're at.


        I may get to the fronts tomorrow, but probably not, as I'm going to Italy on Tuesday night and don't want to potentially leave the car on jack stands in the driveway while I'm gone.

        I also purchased new wheels for the PGT... I think they look alright.

          Let us continue, shall we?

          At the time of the rear subframe swap I had to cut off the rear of the exhaust to facilitate the drop. I originally planned to just weld it back up, but wanted to start experimenting with components for a new setup. Plus the raw mufflerless tone really changed her personality!

          I finally started on the new setup this morning. I had a Varex muffler on the PGT that I'd decided not to use, and instead swap onto the e30. The plan was to mount it in place of the stock muffler, but upon test fitting into the stock muffler brackets, realized it wasn't going to work. First step was to remove the bottoms of the brackets and shorten them so they would firmly hold the muffler in place.


          Tried another test fit that went well in terms of the brackets being the right size, but the inlet for the muffler was right up against the cv shaft, and the outlet wasn't pointed in a great direction. So off it all came again for more modifications. Cut the bracket hangers off and lengthened/rewelded them to move the inlet down and aimed more towards the center of the car.






          Also managed to point the muffler outlet in the correct direction as well


          Now I had the issue of merging the dual 2" piping into single 2.5" piping. I'd looked around and wasn't having much luck in finding a y-pipe that would work well, so I went about the task of welding together my own. Had some extra pipe sitting around and actually managed to weld together something that is pretty much perfect.


          With most of the trial and error stuff done, I'm planning to purchase a proper tip and bring the car to an exhaust shop to run the small amount of piping to get this all connected. Then I'll need to run the wiring up to the front for the bypass switch.






          More to come!

            Met Bill this weekend, sounds like the S52 should be quite a bit of fun when you get it installed

                  Finished up the exhaust this week. Amazon delivered the dual tip on Monday so I rushed to an exhaust shop after work to get it installed.


                  The Varex muffler thankfully has a flange on it, so I had them keep it to make things more serviceable.


                  While it was up I also got to see how the suspension looks fully compressed. No dead coils and a good amount of available compression.


                  All in all it went pretty well, but unfortunately I could only see the fitment from underneath. With the car back on the ground I feel like it needs to go in about an inch. Oh well, easily fixed.






                  So I didn't mention it earlier, but when I had the Lukebox out to do the rear suspension, it took a small spill and the sub ended up ripping it's screws out. This is mainly because the box cutout for the sub was slightly too large. This had been a known issue since I bought the box, but I had just been living with. I took this as a sign to finally find a sub that would fit correctly, and after some research ended up with a 12" Image Dynamics IDQ. As you can see I ended up installing it 90* offset due to the old screws ripping out.


                  While I was in there I hooked up the rear speakers to the stock deck, and painted the rear parcel shelf, as it had faded quite a bit. Need to find a UV resistant fabric to wrap the parcel shelf. Oh, also painted the sub ports.




                  While I was figuring out the rear speaker wiring, I also took the opportunity to run wiring from the muffler up to a switch above the deck.



                  Switch doesn't quite fit and will need some trimming, but it'll work for now.

                  Why on earth would I need wiring for a muffler you ask? Because the Varex muffler has an internal cutout! Honestly at first I thought maybe I had it wired incorrectly, because it was so quiet when opening the cutout, but after driving around for a couple days its really started to open up. It actually provides a decent amount of volume reduction for a straight through muffler when the valve is open. Videos to be posted next weekend.

                      Well I've driven the car to work all this week and am absolutely loving it. With the exhaust now in a place that I surprisingly like, I feel like the car is really coming together. As a result, I've finally started working on getting this s52 put together. I've really been putting it of because the motor isn't complete and having never worked on an s52 before, it's not immediately clear what I'm missing. Thankfully however, I do have a spare M50 sitting next to it that I can reference. I started this week with a very easy task, installing the headers. I have stock s52 headers which have been coated in black with new gaskets, but there are no header nuts and half the studs are missing. So off to the M50 I went, pulled the nuts and 12 exhaust studs and gave them a good rub down with a SS wire wheel on my drill.

                      Of course I had to take the obligatory exhaust valve shot before they were covered for the foreseeable future

                      I know it's a small step, but it's the getting started that counts! I've got some PGT work to attend to this weekend, but I shall have more s52 updates in the near future!

                        Knocking out small steps, especially while everything is new territory is a smart way to go. Makes sure that each step is done right and not rushed... keep it up

                          Thanks mang! I may consider bringing someone local in to help if I run into any big issues, but considering I just did a cam install on my PGT motor, I should be in a good place to complete this on my own.

                            Made a few more steps. Managed to get the cams installed but unfortunately am missing the exhaust cam timing components, so waiting for those to ship from a seller off ebay. I'm actually realizing at this point that there are quite a few pieces I may not have which could be a significant blocker going forward. Also realized there's still quite a bit of $$ to go before this is done! Over $1k just in engine related maintenance items! Yikes!


                            Up next are to get the timing set, VANOS installed, and valve cover in place. Will update soon!
