Drift-Office : Re-Introducing the NEW HEXON RR350 Turbo Kit! - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Drift-Office · 03-03-2015, 03:37 AM

Let me first preface the article by saying that this isn't meant to discredit any specific brand or highlight any deficiencies with any one specific kit since this offering from Hexon is a variant of 3 others currently on the market. While some might feel that "JDM brands" are superior to those that of ones coming out of say China or Taiwan, that's not to say said JDM brands aren't made there as well. Regardless of which, there will be natural comparisons o I will do my best to showcase the differences within the text herein. As always, it will be entirely up to you, the reader to decide what you will.

I will also say that I had never been much of a fan of top mounted turbo setups. You'll find in the pages of this forum and elsewhere that I'm generally adverse to these setups only because I look at things from a shop perspective firstly, to which what we provide for all shall not be a liability on the street (and on the track) and secondly, from a long term reliability standpoint. Many of you here know that I have a pretty kick-ass AVO setup in my “whip”, but no means would this be the final word. After all, everyone is different and their needs have different expectations.

It's with these different expectations was what brought an existing supercharged customer of ours back to us in hopes of having us find a solution for his needs. He's typecasted as the weekend track warrior with an emphasis on a “show” setup. Previouly before, I've done several top mounted turbo installs and tunes on the GT86; 4 Greddys and 3 others, notably the SBD, RP400 and FA20 Club variants prior.

By the time of this writing, we would have also completed our 25th AVO turbo kit install and tune and that was one of the explicit reasons why a different offering was sought. Since the customer already had the supporting mods (upgraded clutch, radiator and oil cooler,) we looked into the Greddy but I had felt that the turbo was a tad small and secondly, I wasn't too impressed with the charge pipe layout. We had toyed around with getting one from Greddy or SBD and then modifying it to meet our expectations, but that would come at a prohibitive cost to the customer.

What if, however, we were able to find a manufacturer that was open to make the modifications for us?

Enter Hexon Autowerks. On a recent business trip to Taiwan, Drift-Office had visited Hexon's establishment and met with founder and owner Wayne C and a conversation ensued. When asked why we didn't favor top mounted kits like theirs, we pointed out that with the high static CR of this vehicle and given our much lower octane (91-92) here in the US, several issues would probably surface especially for those constantly in traffic / gridlock and in higher heat and or higher humidity conditions.

We highlighted the above mentioned points as well as the oil return hose commonly featured in these kits that we've seen get brittle and crack over constant use - to say nothing of metal heat shield that the other kits utilize which would exasperate rising IATs in the summer time. It's been from my experience that most companies don't really care too much about what we think since their job is to sell product, not assume the liability like we do as tuners. Unlike other companies though, Hexon / Wayne had already addressed some of these points and unbeknownst to us, was taking mental notes and was planning to make subtle changes based on our discussion.

Imagine our surprise when we received a single communication from Hexon that the kits based on our recommendations were ready to be shipped. When we first saw pictures of the alterations that made it into production, it peaked our interest. Here's a fresh idea – a manufacturer who listened and was willing to try our new ideas! Somewhere in the discussion and translation that followed, a challenge was then issued and we were asked to do our best (or worst depending on how you look at it) and put the kit thru it's paces. A few short weeks later, we had installed our first HEXON RR350 kit and these were the results on a 6MT 92 Octane setup...

Here's a few bits of the changes / features :

A redesigned equal-length manifold, providing for more room between the turbo and the engine, thus allowing for a larger turbos as opposed to one specific T2. This also yields better airflow and performance in higher boost.
Reducing boost creep common in current offerings by running the wastegate pipe directly into the header. More commonly, other kits are internally gated.
AN oil line and fittings to ensure maximum reliability and eliminating the inferior oil return hose wrapped in heat cloth. This is a Drift-Office exclusive offering during in-house installs.
TiAL Wastegate Standard.
TiAL Blow-Off Valve Standard.
Thermal Turbo Blanket Standard. (PTP Upgrade Offered!)
2.5 inch Cross-Over pipe Standard. I don't think any of the other kits offer this as part of the base package.
V-Band down pipe with an extra 02 / EGT bung Standard. Not having a downstream 02 bung is one of my pet peeves while tuning on the dyno. If you didn't have one and because some cars are catted, 02 readings sniffed from the exhaust tips would be different from the one on board, but not anymore with this setup.
Thermal coating on charge pipes and FMIC.
Vented Crank Case Filter System
Perrin Intake Filter

Here's the obligatory YT Link...

[ame]http://youtu.be/k-dQI9s_hQ8[/ame]

MSRP : $4,000.00

Considering that you get OVER $1k of accessories with this kit (TiAL WG / BOV / Thermal Coating / Turbo Blanket / 2.5 Inch Overpipe) that makes it less susceptible to heat, this I feel is really the best solution for those looking for something more than a "sleeper" setup!

Professional installation is highly recommended as this isn't something people should attempt to do unless they've got access to a lift, a full compliment of tools or bring it to a shop familiar with working in tight spaces!

As always, we'll be testing out more upgrades in the coming months and will be pushing it further via E85. Stay tuned for those results!

Wow, I haven't seen you around these parts in months. Welcome back.

That is a beautiful torque curve.

Would the thermal coating on the intercooler prevent cooling?

Raven604 · 03-03-2015, 08:08 AM

No thermal coating on header / down pipe?

gl2filmerguy · 03-03-2015, 08:32 AM

Nice! The kit looks great!

Yeah, that is gonna pass right by the pass side cam sensor harness, if it gets too hot your gonna have a bad time

My fa20club header melted mine, but it was catted and the cat sat right by the harness reducing clearance. Exhaust wrap is cheap though, and it shouldn't cost much to have the pipe coated.

Been super busy on 2 different platforms, plus with the various different headers that's been introduced and this kit, I did't really have a lot of time to update my findings.

As far as the FMIC goes, the logs would show that the IATs were lower and sustained better cooling than the non coated ones from the other kits that came in that same week.

That's a possibility, but in trying to keep costs lower, we elected to not do so. Then again, I don't feel the heat generated there is as critical as up top where the intake / charge pipes are.

Not sure about that since it's up to us as the installer to look out for that sort of thing. We've done 2 kits, this one the 6MT doesn't show any signs of "a bad time" while the other, a 6AT drove from Seattle to LA to MI and it doesn't have any issues with the harness that you speak of.

Figure another $200 - $300 for exhaust coating, or if it's a must have for you guys and you can do it cheaper, then I suppose you might as well find your own source and have it done before installation.

If you want someone as a tester for the kit, I am more than willing to be that guy! haha

cdrazic93 · 03-03-2015, 03:10 PM

by the size of the turbo and dyno, id say its a 20g variant? Although I never asked you what size it was at the show haha.

The 2 spots for 1 MT and 1 AT tester was filled within 4 minutes of my posting it on the local 86 FB group.

Thanks though!

Is it safe to say you can get the same power out of 91 octane that you are getting out of 92? Or is there that much of a difference?

I am waiting for the day that 300whp on 91 is a solid and tested claim!

There is that much of a difference. We're further up North, cooler climates, less heat, better gas - I doubt this will be good for 91 Octane setups. It'll run, but it won't be no 300WHP.

I'll be doing some lower octane setups later, so more on that when it happens!

UGH. I know I was reaching with that one.

I think the demand for a 91octane turbo setup is big though. Maybe we'll see a dyno chart soon?
