Yep, if anyone is using the newer LT version, make sure you tell Eric at AE Auto this if he is making your adapter plate so he can pocket for the external balance weight. The one piece rear oil seal alone is worth the updated style.

That's what's kind of ok about the LT-1, it's a newer gen of the small block.  Lots of those holes are in the same place on the front.  I.e. heads,  block,  where to mount.

Simple Man, I am not trying to hijack your thread either but this info might be of use.

Sisqocracker, I use a small block instead of the newer LS blocks for several reasons, the shape of the bellhousing, the price, the lack of computer problems (especially when connecting it to a non-computerized and probably foreign transmission), and others. One other reason is the accessory drive belt assembly. When a serpentine system starts rearranging things, it is not easy to do, especially with the idler pulley(s), it is expensive, and it is limited. Also the water pump is a nuisance as you stated. With a small block, I can I can start with the old style but readily available short (5-3/4") water pump, which allows me to move the rear bulkhead back and gain critical inches of legroom, then choose any combination of readily available brackets and v-belt pulleys. Even if I cannot find the right bracket, ones for the small block are easy to fabricate, and no idler pulley to deal with. I find it a much simpler and much more economic solution.

Sounds good.  I have an LT-1 from my 95TA. 6-rib serpentine belt.  V-8 Archie kit so it is ready on the bottom next to the harmonic balancer with the A/C mount.  I need one that I can hang my Alternator on and work out a belt tensioner.  On the LT-1 the water pump tends to get in the way.

Thanks,
Coop

Sisqocracker, Old Air Products, who I have been a dealer for years, has many styles of alternator and compressor mounts depending on location desired and engine/head combination. Once more I have found that the unique requirements of a mid-engine car called for something not quite a standard piece. They were adequate but the stock items did not exactly give me the combination of low and close that I wanted, and I tried several of them before I finally reinvented the wheel and made my own billet CNC design. They fit a small block Chevy with aluminum heads, $150 for the pair.

Say 76, I'll probably look ya up when I get to the A/C part myself.  I'm thinking I'll smoke the 32 year old system out of my 85GT and put in a new one.  :-)  Right now I can only have the Alt as I have no other bracket ready to go for having both compressor and alt.  I'm using the A/C compressor location to put my alternator at the moment.

Glad I ran across this post.  Thanks guys.  Not trying to hi-jack it.  Now back to our regularly scheduled program.  ;-)

Thanks,
Coop

The 1100, 2100, and 3100 are electronic and what was quoted. The 1000, 2000, and 3000 are cable. That electronic controller adds $200. Parts are the entire Hurricane System but they make a special one for me that has a hoses and fittings package more suited for a mid-engine configuration. You want the 1100 for that application.

SM,
   That compressor is a couple of hundred dollar part that comes with the complete system for $1,250. You can buy all of the parts individually, without the compressor, but that is probably going to be over $1,250 and you still do not have the system tailored to a mid-engine car.

Can you provide a list of the parts included for the 1250$? Would also like the electronic version & billet slide control #45-0114B.  Also I'm not sure which would be best for the ferio the series 1100 2100 0r 3100. Thks 76!!

I called old Air
They state the Hurricane system requires the use of a fix displacement compressor. They also recommend a parallel condenser.

The Grand Prix Gtp has a variable compressor, which could be made to work with the fiero system... or so I have been told.

Let me comment a little further so not to confuse anyone, some of the old ac compressors could handle R12 and R134 and some can't. If you put R134 in a compressor that it isn't meant for it will burn it up. Just check and see if your compressor is compatible with both before doing the change over.

I'm no certified mechanic, but when I changed my Fiero over from R12 to R134 all I did was drained the old freon installed the new fittings for R134, then oiled and refilled it with R134. No cleaning or modifying of the old compressor, just drain and refilled with new and drove it almost 5 years no problems. Agian I am not a certified mechanic so what worked for me may not be right but it worked, make sure to check with an actual mechanic before doing this as not doing it the right way could end up ruining the compressor.

Exactly right Sisqocracker. The Freon changeover was late 80's-early90's, there is not a firm date for all models. You can drain, clean, and modify an old compressor to work with the new Freon but it is more trouble than it is worth, and you still have an old compressor.

HA HA!  Good one 76!  My 95TA was a "new" type, so yeah should be good.  I'm sure 76 would say (y/n) if he knew the year you were talking about.  I reckon ya meant newer GP instead of old 80's an older GP.   ::headbang

I started to say yes if it was a new Pontiac, but then I thought about it again, where did you find a new Pontiac?
