The bottom right bolt I was able to get from the top with a 3/8 ratchet and short extension. the rear 2 I got with a long 14mm wrench, reach up past te test pipe/cat under neat the car. Now, it appears, hey look there is the nut on the top of the mount, just take it off.well its not that easy, the way the brackets are designed a wrench will not sit in there flat, let alone have room to turn it, so I took off the 4 bolts to the bracket off the block. I went for the passenger side mount first due to there being more room over there. sigh, there it is right by the ac compressor!Ģ. I removed my Zspeed under tray and went around the front. This is a good time to remove your strut brace and air intakes! Ok some inspection pics.ĭriver side mount from the rear.oh crap. Ok, this one is a bit tougher, first I looked around to assess the situation, I looked around to assess my point of attack, the Z1 instructions(no offense Z1) are useless.they just say take them out.They imply to remove the bracket from the engine, which I did on one side only, I will share why later. If you did not support the transmission, at this point you will not be able to put the 4 tunnel bolts in, you need to lift the transmission up.ġ. Install the cross member back into the car, Z1 provided bolts to attach the mount to the member as you can see above the Z1 mount does not have long studs, it is threaded. It is now time to reverse all this, attach the new mount to the transmission with the old bolts you removed.ĥ. Remove the 2 14mm bolts holding it to the transmission.Ĥ. Lets get the old OEM crap off the transmission now. Now we need to remove the member from the car, there are 4 bolts, 2 on each side of the tunnel, and there are 2 nuts inside the member, you will need a deep sock for those, everything here is 14mm.ģ. just go to the end of the transmission and the black metal dodad is the cross member.Ģ. Lift the car and support the transmission by a pole jack, floor jack etc, when you drop the cross member the tranny will drop about 4 inches. Now on to the good stuff, first up is the trans mount, again this one cake! Im am not a photographer, so the pics are not perfect, but they get the point across.ġ. The best thing is the power delivery, I also have Whiteline poly diff bushings, but now I describe the power deliver as ON or OFF, when you slam the throttle down, boom, power, its hard to describe, but that is the best way I can convey how it feels. My only regret is not taking a before and after video of the engine, because it does not move now, if you open your hood, sit in your car and with the hood up look through the gap, you can see the engine cover, if you rev up the engine, one can see the motor flexing back and forth, this now does not happen at all. The transmission now does NOT move at all, in fact, there is less vibration in the shifter, before I could always feel the transmission moving and flexing under acceleration, shifts are solid and more crisp even an improvement over top of the ralco short shifter. Review: Holy mamma, why didn't I have these long ago.The difference is astounding, there is some vibration at idle, it is minimal, and the only other place it is really noticeable is on a high RPM deceleration, NHV in my opinion has such a little impact, it is negelectable due to the benefits. I had full access to my techs tools, you need multiple sockets and wrenches from 14-19mm, ratchets, extensions etc. Time: 4 hours Pulled the car into the shop a little after 9 and finished the trans and engine mounts just before 2, including lunch, I did run into one hiccup, if I had know better and did not need to ask for help, I could have cut about 45 minutes off the time. IF you do this on jack stands, it will be harder, but I still say its doable, the engine mounts that is, the trans mount is cake. Ill post the review first, then to business!ĭifficulty: 7/10(with headers being a 10/10) This is not difficult if you have the proper tools, it is a bit time consuming, and your procedures may differ than mine due to what you have installed, I have Z1 headers(if you ever do headers, do not be a dumbo like me and not install the mounts then, but I save a bunch with the Black Friday deals). I did not see a DIY for these, if there is just delete this thread!(I hope not.) We are having a few mild winter days here is PA so I brought the Z out of hibernation and down to work(since I was off today!) and install all my Z1 Black Friday goodies! Also did ss brake lines and 2 piece front rotors.
