Evo 3 air conditioning compressor /lines

[EVO-00X]

Nothing wrong with AC. It doesnt rob stuff all power when it's off. :thumbsup:

 

[justincase]

Nah no race car Jamo, just a shopping trolley with a bit of poke.
I'm sure it will see Wakefield more than a Krispy Kreme car park though

 

[evo-gsr]

I meant the other pretend race car.

 

[justincase]

it's just a collection of parts and a rusty shell

Have any of you guys swapped a six bolt into a CC GSR and successfully retained the aircon? Would like to ask what parts you used so I can track down exactly what I need

Not entirely sure why running a 6 bolt would make any sort of difference? Does the AC pump bracket and passenger side driveshaft bracket not still bolt to the back of the 6 bolt block as normal? Don't think you run a different crank pulley either.

Ive got the passenger side shaft and the 6 bolt block bracket, all fits up fine of course. But what I dont know is whether I have to use a six bolt compressor, because if I do, i'll need to figure out what lines to use or whether I'll have to make some from scratch. If it's possible to use the CE9A compressor (and therefore lines) it would make the job much more straightforward.
And also, which tensioner bracket I need to use. I'm guessing the one to match the block bracket. But I'm just guessing, that's why I'd like to ask someone who's actually done it

Given that the only interaction between engine and compressor is a belt, I'd say engine choice is irrelevant.

So long as the tensioner bracket still bolts up, I'd say just use the existing AC system components. There's no reason I can see why you would need, nor want, to change any of it.

Yes, the six bolt tensioner bracket should bolt up fine if I use a six bolt AC bracket, as all of those components are 6 bolt.

The question is whether I can use a seven bolt compressor on that bracket and therefore use Evo AC lines (which should fit straight into a CC GSR). If I have to use a six bolt compressor, then Ill need to look into getting new lines made up, as the two compressors use different fittings. (Eg, cannot use Evo 3 AC hardlines on Galant VR4 Compressor afaik)

I have no existing components, so I cant test fit anything other than the 6 bolt compressor bracket.
Its a 4G93T Lancer GSR, compressor is in a totally different spot. So my choices will be either 1. Track down evo AC lines or, 2. Get new custom ones made.

 

[khubner1]

if the compressor bolts to the bracket and the belt matches it will work fine

 

[3VOLUTIONIST]

If
Thats why I was hoping there was someone who had swapped a 6 bolt in and retained air con

You say you have a 6 bolt bracket, yes?

Bolt it to your existing engine. If it works, then the existing CC GSR bracket will bolt to the 6 bolt block as well, and will answer your question.

Im confused, what does a CC GSR Bracket have to do with this? the GSR AC parts are totally unuseable when doing a 4G63 swap, the compressor is in a totally different spot and the block is different.

 

[EvoMayhem]

Right, let me get this straight.

All you currently have, is a 6 bolt bracket, and a CC GSR? You have neither any 6 bolt AC parts, nor any early Evo AC parts?

I take it that there is no one local to you that you could take that 6 bolt AC bracket to, to confirm it bolts to an early Evo AC compressor?

(I wasn't aware that the CC GSR compressor bolts anywhere other than the rear of the block, hence my confusion)

My bad, I just realised you're not from Australia, when we say GSR we generally mean Lancer GSR 1800 (4G93T). The compressor is where the alternator is on a 4G63T, so you cant reuse the bracket/compressor. They're totally wrong.

Someone locally will have an Evo compressor, but without having the engine there to test fit the parts on, it makes it impossible to verify that the pulleys all line up in the same plane. Maybe I'll try and track down the parts and borrow them, to try and mock something up

 

[Cranked]

I'd just go a 6 bolt conpreasor and bracket, etc. And then see what hoses you can use from a Gsr, a Vr4 or GGSR. Would think you could work it out as you would only need the High pressure line and Low pressure line to and from the compressor.

To answer your question- from what I can see it would appear that yes you can use the evo air compressor on the 6 bolt block then use your evo AC lines. The AC bracket is the same and the compressors bolt up the same-but that is assuming the brackets I have here are actually 6 bolt (i have some from off 6 bolt blocks). The bosses for the ac hoses are different between the 6 and 7 bolt but that's all I can see being different. I've got both compressors here and both types of blocks and a few brackets so if you need pics for confirmation let me know.

Worth noting that the rvr, even though a 7 bolt, has a different bracket and ac compressor to the evo 7 bolt and they cannot be interchanged, though the mounting bosses on the blocks are the same.

I've attached a photo of the Galant AC bracket (thats the part I have). I wasnt able to find a photo of the Evo bracket, but I remember seeing a photo of it, and unless someone had painted it silver, it appeared to be made from cast aluminium, which would make it pretty unique in your pile of parts I imagine.
Would you be able to check an Evo compressor on a 6 bolt block bracket, and make sure that the pulley is still in the same plane as the crank pulley (the belts line up)
If that's a yes, it'll save me a lot of headaches trying to make galant AC parts work with custom stuff.

I'm guessing I'll need a 6 bolt tensioner bracket? (probably to prevent clearance issues on the timing cover, as I know they vary between the two engines)

 

[evo-gsr]

The Evo bracket is not silver. They are black like the ones above.

Oh? The one I saw mustve been painted then. Thought that was unusual
