Rotary Extreme Twin Turbo Track V-mount Kit - Preliminary Review
 

I had been having issues with keeping my lil monster's temps down with the abuse I was throwing her on track with an HKS S-Type Front Mount Intercooler (completely engulfs the main air inlet) and Fluidyne Radiator. Come to find out in the install of the new kit, a majority of this may have been due to hacked fan wires. Regardless, doing track days with several hot laps followed by even more cool down laps felt like a big waste of money, versus one warm up lap, reliable hot laps, then a cool down lap.

After a series of lackluster track days in 2010, my FD took the back seat while I became embedded in my new professional endeavors. Fast forward to the fall of 2011, where I was sick of my RX-7 playing a role as an oversized matchbox garage queen, and decided it was time to put some focus back on her. Priority number one: get those water temps down!

I had been talking with Ben at Rotary Extreme about some ideas and how I wanted a v-mount kit, but wanted something a little bigger than his twin turbo kit. He was all about it and proposed some ideas for updating his Track/Togue kit with twins. To throw a monkey wrench in on him, I also wanted to retain my HKS RS kit. To him, this would not be a problem at all.

I let the idea of going with a custom kit settle in, and in the interim, GReddy's kit became more relevant in the community. I went back and forth on GReddy's kit and what Ben had proposed for a custom kit. After realizing Ben's kit fit all my needs perfectly, lusting over Rotary Extreme kits for over half a decade, and seeing the awesome kits Ben was pumping out, I decided to go with RE over GReddy.

After unpacking it and installing it, I am absolutely happy with the decision to go with Rotary Extreme. I have a great amount of respect for Horacio Pagani, a great appreciation of form beautifully intertwined with function (see Zonda R, Revolution RX-7, or even the FD3S out of the box for reference). Upon arrival, I thought the kit could have fit in just as easily hung up in my office as it would in my engine bay.

As for the kit itself, it is a soup to nuts complete kit. I don't envy the work he had to do to build a complete custom kit on his car, ship it to the east coast, and hope it worked out perfectly on another FD. Installation went relatively well, with Ben being very responsive to offering pointers and help along the way. Being 80 minutes from where Mia's garaged, it took us several weekends working around mine and my friends schedule to get it done; but alas, it's complete!

I will have a full review on response after I get some more seat time.

Please mind the dirty engine bay. I pretty much buttoned up the kit, took some pictures, and had to head back to Providence. Actually - after several months of sitting, the whole car needs a thorough detailing.

Big thanks to Ben and Mark, Adam, Brian, and Tony with the help on install. And my Polish Princess for her patience with my series of weekends away.

What do you guys think?

Looks very nice. Im looking to buy his V mount setup when I start getting into heavy power mods. He's local to me too.

Id like to add that I made this kit work with the HKS intake pipes so you can keep all youll emisions. The primary turbo HKS filter can be retained but you have to get creative to plumb the smog pump in. Also take a look at that ps cooler on the driver side behind the IC !!!.

With my intakes for this kit, all emmsions can be retained. All vacum lines are retained. A/C works with this kit.

I worked hard on this project so that if you know someone or smog, you only need a deal on the visual, as long as you have your cats it will pass emmisions.

On my intakes, they also end up where the HKS ones are.

The kit is pricey, but worth it. I only recommend my intakes or HKS because I know they will work.

Thanks or the props ZumSpeedRX7.

More products comming in the future.

Ben

Ohh im in love!

Nice job Ben. Rotary Extreme V-mounts kits have always been the best on the market. Even better than the JDM kits I've seen and handled in person. Pics just don't do justice to everything included in the kit - brackets, mounting, fit and finish.

Looks great. LOVE the idea of it on twins

Yes, I did put love into this kit. I really enjoyed making it. It was such a challange to make it work with everything. I spent alot of personal time and money on so many different designs, custom cnc'd pieces, little changes here and there, thought I had one part right then realized it conflicted with something else. But I finally completed a functional and presentable track ready kit for the twins.

This is def the kit that will go on my own car !!!


I am doing an install on another car with this kit with my intakes and I will put that on my site. But I will respect this thread and not jack it anymore...lol

This kit is bad ass, not cuz I made it, but it really turned out pimpin... hahahaha

Great kit. I got my oil cooler kit from Rotary Extreme, very pleased with it.

No worries, Ben. You made the kit, all I did was install it.

+1

My kit continues to perform flawlessly. Intake and water temps... a NON-ISSUE :D

No info on your site?

Well, Im waiting for driver feed back to oficially put it on the market. I am also waiting to put it on my site until I finish an install with everything fully plumbed in.

I need more feed back before I offer it on my site.

Send me one, and I'll get you feedback right quick like.

The kit looks amazing!

I believe I took my last order a few weeks ago.

I am not taking any more orders on any vmounts untill all current one are done.

So I would say I'll be ready to take orders again in about 4 months.

If you really want one I would be willing to take one more order before I close for a while.

I am extremely backed up.

:icon_tup: for a well built kit.

very nice kit , this is exactly what i want!!

me too!!!!!

Is this kit for sequential or non-seq turbos?

I'm assuming that if its for sequential, you still have to use the rear 1/2 of the Y-pipe (the part with the flapper & CRV).

Any pics of it with the intake pipes removed?

You can use it for both set-up.


But seriously, a small single turbo is better then non-seq.

Yes I have 2 cnc'd pieces, one that goes to the rear 1/2 of the y-pipe and the other to bolt straight to the pri turbo outlet. The piece that goes to the pri turbo also bolts directly to the 2nd turbo outlet so you can eliminate the 2nd turbo y-pipe and crv.

This kit allows you to retain all emisions, you just need a hook up on visual.

I really do not want to release detailed pics due to reverse engineers. I reserve those pics for customers. But I can not stop anyone else from posting pics...lol


Ben

I've taken the turbos off enough times to know how they work, so I think I have a pretty good idea of how the setup mates up to the twins. Looks like a very nice kit.

LOL not looking to reverse-engineer your kit, was just wondering. I've already trashed 3 sets of twins on this car & going single now.

I don't want to sound like its all super secret, it really isnt. I just want to have it on my site after I do an install and I would like some driver feed back first.

Then I will be more then happy to share with the world. I dont know if I will need to make a change here or there. The install is very involved. I just want to make sure that when I flood the forum with photos with official release pics from me that the photos include the final production version.

I would like to make sure that I built a great product and that it performs as designed. I know the idea will be copied once the results are in if there is really that much of a difference. I dont mind if regular people copy the idea. What I dont want is for some other manf to copy it and put their name on it for resale. I guess I just want whats best for my company. Recognition that Rotary Extreme made this kit first.

I do like the fact that Greddy continues to offer stuff for the 3rd gen and I like their vmount too. But I offer more with my kit. I am also 24 hr tech support for my products, I'm just a phone call away...lol

ZumSpeedRX-7 did take some really cool pics of the parts when the kit arrived.

ZumSpeedRX-7, can you post those.

Ben

Sure thing.

GReddy elbow and HKS BOV flange were extra.

Pretty damn complete kit. It came with two comprehensive write ups on install, but we still had to reach out to Ben along the way (I took the lead on the project, and well, I sit in an office for a living and am not entirely mechanically inclined - about damn time to start learning!). Ben - I owe you at least a drink for all the effort you put in after it left your hands. Honestly, I appreciate it!


I will finally get the chance for some much needed seat time this weekend. I'll post up a full review after, as well as some cleaned up engine bay pictures.

Thanks bro!!!

1. did your radiator arrive with those fins bent?

2. For everyone who is wondering: that big black cooler is the PS cooler that comes with the kit to replace the s-line. Yes the top line is purposely bent to assit with the 45 that screw onto that to clear the line. Everything is included for the swap.

3. You can see the ss tow hooks in the pic.

4. There is one blue elbow that should be black, the manufacture ran out of black. I did not surprise him with a blue elbow.

5. The two bottom pieces in the middle under 2 45 degree pipes are the key pieces in the kit and they come pre-fitted with nipples for the vacuum lines.


So as you can see, this kit is no joke. You really get what you pay for.

Ben

im confused on how your intakes are set up. i would love to buy from rotary extreme and i like the looks of this setup but i just want to know what intake craziness you got going on. i cant wrap my head around it cause i want to keep my twin turbs
