Guest Craig280z Posted June 4, 2002 Share Posted June 4, 2002 I found out today that the A/C compressor contacting the frame rail is not an issue with my 78 280z, 95 Firebird LT1, and JTR mounts. You have to remove the A/C compressor in order to install the motor mounts. So, I have searched the archives and I don't see a solution to removing the power steering pump and A/C compressor. I have been to allangrove website, and one other one but they both mount the alternator low on the passenger side. Has anyone tried any of these? Does the Alternator clear both the motor mounts and the frame rails? Please, tell me what you did. Thanks Craig Quote Link to comment Share on other sites More sharing options...
Guest super280z Posted June 5, 2002 Share Posted June 5, 2002 nope, it dosent clear in a low mount. try this: http://www.marchperf.com/pg18.html http://www.marchperf.com/pg17.html Quote Link to comment Share on other sites More sharing options...
Tim240z Posted June 5, 2002 Share Posted June 5, 2002 Craig, I am having the same issues. I want to delete ac and ps. I plan to make another idler pulley to pull the serpentine belt away from the water pump and use the stock pulley and mount the alt. in the stock Camaro location. McMaster Carr has the hardware necessary. I haven't done it yet, so I don't how feasible it will actually be, but after looking at the engine for a while, it should work well. The only variable at this point is finding the correct length serp. belt. Tim Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 5, 2002 Share Posted June 5, 2002 Someone makes an a/c delete kit (cant remember who)and check the picture for the "homebrew" power steering delete. Tim, Your correct on the belt lengths, they jump from 56" to 59"! I was able to use the 56" with my setup (which would be the same with the a/c delete pully because it is same location and size as a/c compressor) But i had to run an underdrive pulley to make it work.

Guest Craig280z Posted June 5, 2002 Share Posted June 5, 2002 Thanks for the replys. Does the March setup clear the hood? It looks kinda high unless they have something different for just the alternator without the A/C and Pwr Steering. I have seen some old posts about corvette brackets. It looks like their accessories are on the drivers side. Anyone have any experience with these? Right now it looks like the best option is to fabricate something and make the stock alternator location work. Can the pulley on the very bottom that puts the tension on the belt be turned around to extend further in the passenger side direction? Also, what about just leaving the power steering pump in and just not using it? Any thoughts? Thanks Craig Quote Link to comment Share on other sites More sharing options...
Tim240z Posted June 5, 2002 Share Posted June 5, 2002 944, What headers are you using there? Do you have any clearance problems with the spark plug boots (angled LT1 plugs)? Tim Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 5, 2002 Share Posted June 5, 2002 The headers are made by Sanderson, plenty of clearence on all plugs. Quote Link to comment Share on other sites More sharing options...
Guest Craig280z Posted June 6, 2002 Share Posted June 6, 2002 Ok, I talked with somebody that has used the alangrove brackets but in order to get the alternator to work, he had to push the balancer out 2" and the alternator out another 1". See any problems with this other than the obvious possible radiator clearance. I don't have my motor in yet but it looks like, from the pictures that I have seen, that it should clear the radiator ok. What about using just a v-belt on the balancer and alternator? Will that work as good as a serpentine belt? Craig Quote Link to comment Share on other sites More sharing options...
Guest Craig280z Posted June 13, 2002 Share Posted June 13, 2002 I think I have a solution. We opened up the power steering pump and removed the vanes. Capped the ends and going to leave it on the engine in it's stock location and run the belt over it in order for the belt to clear the water pump. I removed the A/C compressor and mounted a pulley in the front compressor mounting hole in order to wrap the belt around the tensioner. This looks like it is going to work. We put a belt on it today and aside from the belt being slightly too long, the tensioner is on the last mark, it looks pretty good. The frame rail will have to be modified slightly for proper fit but the pulley does not touch the frame rail. The belt will be very close though so only slight modification should be needed. A smaller pulley could also be used. Any thoughts on this? Craig Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 13, 2002 Share Posted June 13, 2002 If your at the loose limit now with a new belt you may have problems when it stretches. (if its an old belt you may be ok) You can go with a slightly larger pully at the alternator to take up some slack. Quote Link to comment Share on other sites More sharing options...
Guest LT-1 350Z Posted June 14, 2002 Share Posted June 14, 2002 why you don't use the corvette bracket is way too essay and you wouldn't to modified nothing.check my car at (geocities.com/my75v8z/pics.html) Quote Link to comment Share on other sites More sharing options...
Tim240z Posted June 15, 2002 Share Posted June 15, 2002 LT-1 350Z, Are you running without the MAF? Do you have any pics of the engine from the front (not in the car)? I would like to see how the alternator is placed and belt routed. Can't really see very well from your online pics. Thanks, Tim Quote Link to comment Share on other sites More sharing options...

Tim240z Posted June 16, 2002 Share Posted June 16, 2002 Thanks for the info. What year 'Vette was that bracket from? and do you know if the alt. is the same as the Z28 (1994) one. IE...can I just call Billy Graham's or HP Salvage and order the bracket and then use what I have? Is the idler part of the bracket? Thanks again, Tim Quote Link to comment Share on other sites More sharing options...
Guest LT-1 350Z Posted June 18, 2002 Share Posted June 18, 2002 my engine is 93 and i just bought a blown 94 lt1 from another corvette and they look the same.i think the tensioner is the same on the camaro/trans am Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 21, 2002 Share Posted June 21, 2002 Read Craig280z comment: "I found out today that the A/C compressor contacting the frame rail is not an issue with my 78 280z, 95 Firebird LT1, and JTR mounts" And, Looking at 944LT1 engine picture, I am beginning to think that maybe the 95 LT-1 Camaro engine packege in going to fit in my 74 260Z, (JTR Mounts)with the Camaro accessory brackets, WITHOUT the A/C compressor hitting the the cross member or suspension tower. That would be great, as I don't want to spend the $995 March pulleys wants for a set of high mounts (A/C and Alt only), and have not found a Corvette bracket in salvage yards. Can someone confirm that the stock brackets with A/C Compressor is going to fit? Thanks Quote Link to comment Share on other sites More sharing options...
Guest Craig280z Posted June 22, 2002 Share Posted June 22, 2002 If you read the next line in my post, I say that the compressor won't hit the frame rail because I cannot install the compressor and use the JTR mounts. The JTR setback plates place the motor mount in the exact location as the A/C compressor. I could not install the A/C compressor in the stock location on my 95 Firebird LT1 with the JTR setback plates and motor mounts.
