Tax season is upon us! And so the car parts must be purchased.

I'm currently in the market for a bolt in V mount kit. The reason I say a bolt-in kit is because the Rx7 is currently my daily [I like to live dangerously]. Because its my daily, I can't justify a long downtime for custom fabbing a V mount kit. I daily it in the wonderful summers of AZ so AC compatibility is a huge thing. My goals are a big single turbo and give or take 400-450HP. I'm CURRENTLY on the stock twins in a 90% stock set up. I've got a PowerFC and noticed my AIT's at upwards for 60+C on a 78*F day. Just awful. I've been researching and I've been eyeing the Greddy kit or the HKS kit. The Pro's for the Greddy kit is that, overall, its a more complete kit: it comes with all bracketry, radiator, AC compatible, greddy elbow, and the intakes. The cons are that I have to relocate the battery, and the core is smaller. I feel like this smaller core may not be up to the task of 400+HP on the track. The HKS kit has some pro's too. The HKS kit does not require me to relocate the battery as it comes with a tray to relocate it just in the bay. This is one thing I do like. The HKS core is also a lot larger and I feel will be more up to the task of what my eventual goals are. I already have a KOYO radiator, so I wouldn't have to worry about the separate purchase there as the HKS kit does not include a radiator. The con to the HKS kit is that it is more expensive in the long run due to the fact that I have to purchase the intakes separate.

I've peeked at the Knightsports kit and I believe RE amemiya makes one now too. Just not as much info on those. I would love an Rotary Extreme kit, but they seem to be a little too overloaded to be able to take any orders for awhile :P

Any input from kit owners is highly appreciated.

See if sakebomb garage are having another group buy for the greddy v-mount. I have one but not fully installed. The fitment so far seems bang on. My only issue thus far is the tube which was provided for the condenser input. Looks like the one provided uses different fittings. But it is designed for RHD which is what I have but shouldnt be much to get it ready for a LHD.

 

Whoa am i reading this right? Mr Matt going single and vmount?

 

Check out 1cleancym's build thread, he's running the GReddy kit and I believe he shift the IC over a bit to fit a small battery at the stock location, he's also running a single.

 

Yeah I guess they moved the IC over to accommodate the twin turbo intake filters etc.

 

Greddy is currently the best and most complete kit on the market in my opinion.

 

I'm greddy owner and the #1 reason I chose it was because the ability to retain the AC system.
The second was that I got in on nengun's GB and for a purchse price of $2K shipped, I couldn't pass it up.

 

^ how difficult was it to get AC to work? Heard you had to bend the lines...

 

^ AFAIK that's pretty much it.

 

Well I noticed that with the kit they actually flip the condenser making the input on bottom and the outport on top. Was told that his might hinder the functionality of the A/C but don't quote me on that.

 

Ac works fine as long as it is properly set up. It does take some careful bending of the lines. I sometimes cut the lines and weld them how I need them but that is because I have a tig welder in house.

 

Seems like the consensus is to go with the Greddy kit. I do have a MANA AC system so I'm already anticipating the fittings to not be compliant. Does anyone know if the Denso condenser mounts differently than a Mana? If they mount the same, it should be as simple as getting a line or two made from coldhose. I can live for a few weeks while that kind of stuff is in work. Doesn't seem like a lot of people rock the HKS kit. I saw it in person a few days ago, be it a bit modified, but man that core is huge. I'll just need to focus my attention on relocating my battery while I wait the 6-8 weeks for a Greddy kit to come in. I was told Greddy may be raising their price on it soon too so now is a better time than never huh?

Matt

 

Well I have a denso system and he bent tube that extends the input to the condenser was too big. I think the tube itself was too big.

 

If anyone else gets a wrong tube for there A/C we could probably sway. My car is a jdm version so maybe when greddy created the kits they assumed all vehicles had mana systems.

 

The provided a/c line doesn't work on usdm cars. Its not needed.

 

Doesn't work because of RHD? Or doesn't work with MANA systems? How much bending are we talking here for the AC lines? I suppose since the info on this is slim pickings, I'll probably end up making a thread when I install this that will include all this useful info. Leaning more towards the Greddy kit now. Just need to order the thing :P

Matt

 

Yeah take back what I was saying about that supplied piece. You have to relocate the dryer so the pipe from the condenser to the dryer needs to be bent. And going to the condenser from the compressor needs to be bent. It's easy cause it's just aluminum tube.

 

But the kit eventhough I only have it half installed is pretty easy. The supplied directions are in Japanese but the pictures says it all.

 

I'll let you know when I get around to installing it

 

Like this.

 

it will only hinder the system during times where it cannot dissipate enough heat to condense the gas back to liquid form. However, this is generally rare as the condenser is high pressure and the evaporator is low pressure, with the pump in between.

 

Ok this is good to know. Didn't really want to make new brackets.

 

Just to update this thread. I placed the order for the Greddy kit. Thanks everyone for the advice. I'll document in this thread any issues that arise from the install with a MANA AC system.

Matt

 

Yeah you won't regret it.. open up in another window to view pictures right.

 

was there any updates with regards to the MANA AC system??
