    It probable would adress the overheationg, but not something I would add to my car that I use for track.

    Bigger ps cooler = more weight, more area covering radiator, and more heatsoak.

    Not sure how often one needs to remove valve covers to make such a major change to the breaking system just for that. To me it would be so much easier to lower subframe bolts by about half inch if you need to to take valve cover off and the head probably too if you needed to.

    I do plan to track it but not something built for dedicated track use , I’ll research how to cook it proper . Thanks for the heads up bimerok

    I've had issues with power steering systems anytime I've taken previous autos on a road course. O-ring failure (likely overtemp) to line fractures. Modern sticky rubber put extra load on it. I don't see too many supercharged Cobra's on the circuits...the blower also has issues. KISS is my preference.

    We are interested on how your 210 diff works out...can you say what ball park it will cost for the conversion?

    Thanks.

    hmmmm ok, will have to rethink this hydro business then, guess i have to decide how much i want to go out to the track... although i know once i take it im gonna be hooked.


    Far as the 210mm conversion, i am not done so i might still incur more cost but so far here's what i got. Keep in mind some of my cost was due to me not having m3 to start with, if you already have an m3 most of what i have i don't believe is needed..

    -First i need to convert my rear end to m3
    --m3 rear end from an e36 i picked up for 200 bucks locally, it included everything from caliper to caliper except the diff


    210mm diff from m3 evo and subframe i paid 1600 for shipped to me from the UK, it included the brackets and bolts

    paid 150 for a new 4 bolt style input flange so I can re-use my jtr flange adapter


    From everything i Have read the diff/carrier will bolt into my us spec car and to my newly acquired m3 rear end

    The only thing I am unsure of is the differential, From reading other threads the 210mm diff is longer so a shorter diff might be needed, it's like 3/4th of an inch longer



    I was trying to find an e46 m3 diff, they also use 210mm and thanks to some advice from wanganstyle that's what I was going to do but coudn't find one locally and the evo option popped up so i pulled the trigger, cost woudl fo been around the same for either option anyways, i like the e46 idea because they come with 3.6x ratio

    Since track use is being brought up, you may consider running an upgraded P/S pump. I used a gen 5 from Turn One for my build. Anything over stock rpm can cause issues.

    Since my engine didn't come with a PS pump (from a 14 Camaro SS w/ electric steering), I justified the extra expense to get something I never had to worry about. I have read some of the stock PS pumps having issues after a day on the track, or autox. I think they come from the higher rpm and load issues. The TurnOne actually flows less, which gets the correct flow at the higher rpms. You will have a little harder time turning at lower rpms though.

    There is an option to send your stock PS pump in, and TurnOne will upgrade it for a reasonable amount.

    Mine isn't running yet, but a buddies is and he swears by it.

    I had TurnOne on my LS1 e36. Huge improvement over OE GM pump, which would sing songs and boil fluid at the track. Turn one got rid of all that. They use underdrive pulley and give you orifice adapter that you drill out to your application. If you follow instructions then you will have zero issues with steering being hard at low speeds. You pretty much drill it in small increments until you like how your steering feels.

    Ok guess turnone is the way to go!!!

    In other news I dropped my rear end today, wasn't as bad as I thought it would be. bought an impact gun and that made a hell of a difference when loosening things. Now I don't feel like a hernia is about to erupt each time im breaking a hard nut/bolt.

    Took me 2 hours to drop the entire thing, spent a lot of time just looking over everything to make sure I didn't pull a cable or something.

    Such a shame I just bought all these nice new bushings and i'm going to get all new ones again for the new rear end.....






    As I was pulling it i realized I need to look into my current coil over set, not sure if they are going to work with the M3 rear end. blah

    Update:

    -Had a buddy come over and he welded on the RTAB reinforcement plates, I then gave them a quick spray with Krylon spray paint
    -EVO subframe and 210mm diff are in the car


    Right now I am just waiting on DSS to finish my axles and I can put the rest of the rear end back on once they arrive, I think I might be ok to keep running my driveshaft too, it comes out about an inch from the seal of the tranny still... I think that's enough play for it not to bottom out.

    Reinforcement plates look good. Curious to see what DSS axels going to look like...

    BTW, when you talk about driveshaft play and bottoming out, when are you expecting that play to occur? Once installed, your driveshaft should not have any relevant movement...

    I am talking about the slip yoke from the transmission side, from reading around it has to go in a certain amount but read that it shoudn't bottom out from the transmission side.

    When bolting up the drive shaft to the differential i have about 1 inch of visible metal from the yoke past the transmission seal. I'll try to get a pic and hopefully that will describe it better lol.

    Sounds like from what you are saying that I am fine either way though

    Car is back up and running, today I finished putting all the suspension and rear end back together, torqued everything down etc..

    Felt great to drive the car again after staring at it on jackstands for so long lol, just to document here is everything I did

    -swapped out rear trailing arms, hubs, calipers etc to M3
    -EVO M3 210mm differential and subframe
    -DSS Axles
    -Replaced ALL rear end bushings with AKG poly 75d, that's rear trailing arm, diff,subframe

    New gear ratio is 3.23 vs what I had in there before 3.91


    Everything bolted up using the evo subframe and diff to the M3 rear end, I didn't have to custom fab anything to make it all fit, even the speed sensor just plugged right in.

    Took it out for a test drive and got on it pretty good, car feels great and loving the poly, just feels solid

    Plan on taking it to a car show next week then after that I will be going out to the drag strip again, planning on doing some fun clutch dumps at 3-5k .....

    After I get a few more runs on the drag strip i'll be tearing it down again to swap out the cam and start on the turbo build

    Yesterday my buddy and I showed our cars at a big car show, "Import face off" lots of cool cars there. Pics of our cars attached.

    -Leaving IFO i noticed my clutch is sticking to the ground, when i push it down i noticed there is like a 1-2 second delay from me moving moving my foot up and the pedal coming up too. Never had it happen before and it did that the entire way home.. Hoping it's just something I need to bleed out or replace of the master....

    Clutch Sticking: typically it is fixed with a bleeding. GM has the "best" design ever of the slave (pronounced dumbest)... if you did few launches or track days, the fluid gets contaminated with clutch dust right away. Usually sticking goes away after good fluid change/flush.

    Can't remember if you used separate res for clutch fluid, if you didn't, highly recommend it.

    No, didn't race at all and it was just recently bleed with my pressure bleeder when I did the rear end. Basically I got to the car show at 7am, it sat till about 5pm and that's when the issue started happening as I was driving away. I'll use a seperate reservoir Bimerock, good excuse to get a nice metal one haha.

    Issue with pedal sticking to the floor solved... It turned out to be the clutch spring.

    After my last post I ended up re-bleeding the entire system, no change, the pedal would stick to the floor, I did find that it was doing it more when i would hold it down vs just a quick pump... It would be like a second or two delay before it would pop up. I also noticed the issue would go away if i didn't push the clutch in all the way to the floor.

    I tried a clutch stop but that didn't work, I ended up replacing the following.....

    -Clutch pedal
    -Clutch bushings(AKG)
    -Clutch Master

    I replaced all that and put everything back together, it was a PITA... not because it's hard but because you are in a tight cramped space. After getting everything new installed I went to bleed the entire system using a powerbleeder, then did a manual bleed and it was doing the SAME EXACT THING!!!!! I got pissed off and went online ordered a new tilton master, new lines and new metal clutch pedal...(dumb)

    After calling it a night and the issue still present I just left the car alone and the next day at work I read more on the clutch assembly and did some google research, I found out that the clutch spring actually assist in pulling the pedal down, I thought it was there to prop it up, anyways after reading about some people removing it all together I decided to just take it off and see how it works.

    Removed the spring and the pedal now shoots back up like normal, Drove it around and it shifts beauuuutifully, I am loving the more firm/predictable feel of it too vs with the spring.

    I'm annoyed that the fix was so easy and I spent money on crap I didn't even need but at least the clutch is good now and I can take it to the track next week, I am going to leave that new master in there for now and currently debating if I should return the tilton master i got or turn it into a project for a later time.

    I dropped my pedals to install a new clutch MC. I ran into something similar as you did. I swear I was missing a part for the clutch spring, so I just removed it entirely hoping it wouldn't change much. I'm glad to hear it makes it better!

    That really sucks but glad to hear you got it corrected.

    If I ever have a similar problem, after bleeding the system, checking the assist spring will be next on my list.
