Neither are designed for A/C.... Can you make it work? Sure, but you will start hacking into the supplied ducting and figuring out how to make/bend lines.
These big name companies produce a product for everyone. With this, you get higher cost and less capability of getting a tailored product. RE did exactly that, all while supplying amazing customer service, and ended up saving me money on a few things I didn't. Think Greddy would do that?..... No chance.

You keep saying the Greddy kit is not made to work with A/C, but that is just not true. It is right there in the pictures above. The ducting is made to work with the condenser and the kit comes with pre bent lines to make it work. If you look at the image above the condenser is positioned between the intercooler ducting and radiator ducting acting almost as a splitter of sorts. The ducting looks to be made for it so no hacking there, and it comes with pre bent lines, so no hours spent trying to bend lines.
The RE kits are in fact very nice though. Does he provide ducting now? The last two kits I have dealt with did not come with any ducting, but that was years ago. I do like the RE kits and they are a great proven option that come with everything necessary. And like you said, support that you wont get with the larger companies.
That said, I dont have the greddy kit nor have I seen one installed. I dont even have a VMIC or plan on installing one. But If I were I would absolutely go with the Greddy IMO.

If you're not in a rush to get it you may consider ordering it through Ramy (FDNewbie) on YJA and having it included in his container. I'm pretty sure you will save some money although you will have to wait a bit. I was told he was hoping to having the container landing at end of March IIRC.

There is also plenty of new HKS Vmount kits for sale on there. Your going to need to find it yourself and send him and link because he's not searching for any parts. Also there is quite a few options with these vmount kits so make sure you double check the part no.'s and kit contents to make sure your getting the one you want. Just search for either fd3s trust, or fd3s hks and they should show up.

Also, if using it with working AC is a big one for you, remember that the kit is designed for Japanese cars. All the Japanese cars had the Nippondenso AC and US cars are some ND/some MANA. Also, the AC lines run differently in the US, they go across the front of the engine, JDM cars go straight back from the compressor.
In other words, the AC part might not be as simple and bolt-on as you might think.

Cool as it is, GReddy should bring the price down a bit on this thing and they'd sell more. I can't imagine they're selling many to recoup the development costs, and since it's so new there aren't really used ones around. That said, the most similar product out there, the Knightsports V-mount, is like $4k new.

Not sure if it will help, but here is a full review on my Rotary Extreme kit.

wow, Im smitten by the love in this thread.
ok, here is a non biased response and 2 things that will blow your mind.
and I'll list the advantages and disadvantages of each.
To the original op:
if you have a greddy turbo kit, then your going single turbo? or do you have some type of greddy twin set-up???
If your single turbo then you wont need the twin intakes and youll have to modify the pipe going to your turbo.
Everything below is based on using the twins.
If I had Greddy everything on my car, hell yes I would get the greddy vm... period.
The greddy vm is really nice and I love the fact that they support the FD still.
Also, if your going to dd your car and track it just for fun and want around 350 to 400whp the greddy kit is just fine.
but heres the 2 things that shocked me.
1. They did not do a ground up design, they just copied the trend of the current design of the vm set-up. Some gets are more angled to work better with a stock hood. But what you want is a vm that is closer to the vents on your hood. The cold air comes into the nose of the car and that is the low pressure zone, it is the high pressure going over the hood which actually pulls the cool air up and through the core. If your core is too far down, only hot air is pulled from the engine. This is why you see re-amemiya and alot of other kits trying to get the cores and top ducting close to the vents in the hood. I also know that greddy just copied what most people do and what I used to do with the front relay box which is to just flip it down. You can see this clearly in post 23. So it a nutshell, its a great kit but the did not design anything really that different, but their ducting and a/c adapter is nice. I can have a cnc'd a/c line made... 300 more if you want it, thats why i have not offered that piece. I'll touch more on the comparison.
2. The second thing that shocked me, they basically copied our cnc'd hood damper bracket but added a little difference not to be too obvious, but you can tell where they got the shape from. They just released the hood damper kit not to long ago. **** I feel flattered, seriously... is Greddy my direct competitor on these 2 items...lol
GReddy
Ok, the differences between the kits.
1.a. Greddy uses tube and fin, still a good set-up but ment more for front mount or direct airflow going through it. I have seen greddys tube and fin in person and the internal of the tubes are nicely packed with cooling fins. the greddy core is a good core.
1.b. Rotary Extreme uses bar and plate, more efficient heat exchanger and smaller core can do the same job as a slightly larger tube and fin.
2.a. Greddy core comes with a cool duct set-up and they actually got it right but having the ducting isolate the airflow through the core and not putting ducting at the end of the endtanks. You need to flip the front relay box.
2.b. Rotary Extreme vms are always going through design changes and the newest design is going to be the final design. When I took over RE the vm set-up was already done. But over the years I have continously modified the kits based on field feed back and from what I saw on Calvin Wans drift car. When an issue came up I made a design change to fix it. So now to the ducting comparision. Only the monster vm will require flipping the fuse box because its so damn big but the other 3 vms I have will no longer use a front and rear bracket set-up. With the set-up you have to fab side ducting and its a pain and always risk damaging the radiator and a/c fins. My new design comming out in Jan 2013 is taken from my FC vm's which I designed from ground up. There will still be the back frame rail x-bar but now I have a frame that goes from the front top rad support to the rear frame rail x-bar. The ducting simply bolts onto this frame and the frame sits under the IC core right on the outside of the core itself. The end tanks have l-brackets welded to them and the l-brackets bolt to that frame. So in this I have simplified design, the ducting installation and IC installation. The way my rad hooks up is still the same as the current design. Also the new kit is slightly angled for use with stock hood but still close to the hood to take advatange of the pressure difference with vented hoods and like I said, the front relay box stays in stock location.
3.a. Greddy does not give you a ps cooler kit.
3.b. Rotary Extreme includes a ps cooler kit. Do you think its needed...hell yeah. Your going to race your car at high rpm's for extended times.
4.a. Greddy provides an adapter for the BOTTOM a/c line only. And did you know that the US model 93 a/c lines are different from the 94 to 96 a/c lines. Also the 93 a/c was installed here in the usa ports as the cars came in. I believe 94+ is orginal a/c from Japan. Sooo Your not 100% in the clear with this one. You still have to bend the smaller line.
4.b. Rotary extreme kit comes with a simple system to secure the a/c to the custom rad brackets. this allows you alot of adjustment for attaching the a/c after you have bent your lines. I have been thinking about making a custom piece, I would have to make 4 pieces, 2 for each kit. If you want this option your gonna pay another 350 minimum. Quality and custom parts arent cheap.
The radiator:
5.a. Greddy, I do not know much about it. It looks like greddy offers a complete extension harness.
5.b. Rotary extreme, we use a koyo racing rad with a core that is 2.16 thick and we convert it to 2 pass and change everything to work correctly...yes the drain plug is on the bottom. We give you the wire loom, same color wires, crimp connections, zip ties and electrical tape to extend your fan harness. Also the brackets supporting the bottom of the rad have been redesign to meet requirement that track cars must be x-strapped on a trailer when in tow.
Both kits come polished and both have intake systems with overall comparable prices. but I can tailor my intakes so that the emission tubes are not there if you dont want them.
Down side of greddy is shipping, everything else is good.
Down side of Rotary Extreme is build time. Everything else is good.
Now its hard to compare my kits to this. But I'll do it.
The Greddy VM is about the same as my new street/autox vm with whatever intakes you want to use. The street/autox kit uses a new turbonetics core rated at 485 crank, Should be good for uptp 400whp. It is bar and plate and uses some new cooling technology.
My twin track kit is designed for use with BNR's in mind to maximize what those twins can do. Also my track kit core has alot more surface area. This kit will out perform the greddy kit on the track as it was designed to be a track kit. Also I will note that even though the core is big it has the same boost response as the smaller greddy carb legal stock mount. Where the separate pipes go into the core I have put a divider into the end tank so that each turbo has 7 rows to go through instead on the pri turbo trying to charge the entire core. The boost pattern is the same as it deals with the solenoids/waste gates and charge relief. The twin track kit is the same core as the single turbo track kit.
The monster vm, well you want to make a minimum 500 whp to use this core effectively.
So i can tell you that the Greddy VM will be an awsome complete vm minus the ps cooler I offer. If your goal is under 400whp and you have all greddy stuff DO IT.
But if your going to seriously seriously track your car, Id go with the RE twin track kit.

Here are pics of my small vm which is a direct competitor of this kit.
You can use what ever intakes you want and the core is the turbonetic core rated at 485 crank.
This kit is my prototype kit and does not show the new frame I am talking about that has the integrated ducting and support of the IC.
This kit has 2 supporting brackets for the back and a 2 piece large front bracket hidden under the shield.
but I put this here for visual comparison because it is a brand new kit.
You can also see the ps cooler that comes with all the kits behing the IC in front of the pullys.

Ben did provide some ducting, but it was not a complete seal (which he advised and I understood that it would not). It was a good start but, as I am sure you know, custom ducting is always the best way to go regardless.
OP - I was torn between going with GReddy's or Rotary Extreme's kit as well. I dwelled on it for a couple months as it is a sizable investment, with both being comparably priced. I ultimately went with Rotary Extreme's kit and am more than happy with it. Ben is a member here (Rotary Extreme Sales 1), I am sure he'd be happy to help you with any questions.

This review is a good honest review and that what I needed and thats why on the 2nd kit was improved.
Thanks for the awsome reviews!

Rotary Extreme is hands down the best kit. Most complete balance of quality and price. Not to mention the only kit that supports A/C. If you want a less flashy kit than Defined Autoworks and RX7 store are good choices as well.
My RE kit has been othing short of excellent. Ben is a commited business owner that is always developing, researching and implementing improvments. My kit was complete down to the lock washer.

I'll post the new version of your kit in your build thread if its ok with you.

Your gonna need a big core to support that reliably.
If you want to stay greddy get the biggest front mount they offer and you might be ok but I dont know about for time attack.
This is why I have the monster VM kit, to support cars in the 500+ whp range.
The monster vm core is rate at 785 crank but has supported 1000hp supras at the 1/4 mile drags.. already proven core.
So if you want 500+ whp and want greddy, you gotta do it with their biggest front mount, if you want vm.... the greddy vm is going to fall short.
This is just my opinion, I may be wrong, but Its better to come prepared to WIN!!!

On that note, all things being co-sure, it seems to be pretty complete. At $3600 + shipping, it better be.

for whatever it's worth, just a little nugget for you guys, I learned recently from a strong source that, other than their electronics, everything that GReddy sells is made in china/taiwan.
i'd rather support something made locally, but that's just me. i also wouldn't mind having something that's a 99.9% finished project, so I can argue either side.
but damn, i feel bad for the OP, all he wanted was some 'IMPUT' on the GReddy kit!
immmmmmmmmput hahah

Looking back at post 23 They actually strecth the relay box to infront of the xbar on the rad support.
This will be covered by the air guide so its actually not that bad as far as a air flow issue.
BUT!!!!!
If you keep the air guide you might have to take off your bumper to get to the relay box.
Take the air guide off and you can reach up in there with your hand...
Its just a service issue.
Oh well
I still give greddy madddddd props for supporting the FD in these hard times.

I am currently rebuilding my 93 rx7 in Very Hot Florida. I looked at a few kits including front mounts. After a little research I knew that I would need a v-mount IC for my car. I did a little reseach on what kit I should buy and everything pointed to the re v-mount. I saw the thread on XLR8 and was convinced this was the right kit for me. I called Ben and told him I was going to use my car as a daily driver and occasional track days. I will be running a single turbo set up and he advised me what kit was the best for my needs.I have purchased the re v-mount intercooler and just found out I am getting the updated version. OH YA!

I am also finalizing one more mod before I say anything about it, I need to assemble it on my car and make sure all is good...
but it is related to the a/c.... xlr8, dont say what I told you on any threads just yet.. hahahaha
