Yea, I dont work for HKS but did meet pretty extensively with the representatives from HKS new US department. They are trying to dispatch information to dealers a lot more effectively with their new US branch, and so far I've definitely seen an improvement in communication, whether or not all dealers are taking advantage of that is another topic entirely.

I am in the same boat as you, and I will be installing the kit on a G35, so I will need to do a bit of modification as well. I'm not entirely sure what differences the FX has engine bay wise versus the Z/G but I do have the installation guide from HKS for that new kit, so if you wanted to take a look at it let me know and I can pass it your way. Atleast that way you get a better idea of what you may have to modify to fit your chassis.

As for numbers, I should hopefully be building my VQ shortly, and within the next month or two get the new V2 kit and then break it all in and strap it on the dyno so people in the US will have a better idea of power levels it can generate.

 

That's a good thing. Communication.
Mod's to the unit might be little to none. Procharger sells one kit that will fit both the G or FX. Vortech sells their kit that will fit both the Z & G. My guess is Procharger has more slack in the silicone connectors & Vortech has less but it could also be due to Prochargers intercooler having in/out pipe connections on the same (driver) side or a combo of both. If I remember correctly, HKS's i.c. has both & on the driver side as well. You may already know all this + some.
Damn are you pushy! Kidding. I like your persistence. It's refreshing from the other dealers(?) I've dealt with so far. I think they felt as though they're doing me a favor? They did, without knowingly doing so, which was saving me from giving them my cash.
I'm meeting w/my chosen shop in 2 weeks for a compression & leak down test (92k miles). Should be good to go as I've owned it since day 1 & take very good care of it.
I'd love to see the install guide! This is the best news I've gotten from anyone outside of what's available on HKS's site & thank you. I will forward you questions I have after I read the guide so my questions aren't a waste of time & if you can get'em answered, I may have to drop the other 2 & buy from u! Another big thanks coming your way.
Here's a link to what I've got going on, in case you or anyone else reading is interested/bored;

I'll throw together install pics once I'm deeper into the parts for the build. Still need to source some fuel parts. I've had Uprev for years but I'm not sure if the newer versions let you turn off cat related codes like the older versions did.

 

Very cool. Don't use photosuckit!

 

Hey Intimazy, Can you post a pic on the Intake routing of that KIT? I Actually had version one of this kit when HKS left the US I bought the prototype. I pulled 398whp 380tq on a stock block.

Mods were Headers, exhaust, intake spacer. Stock cats. HKS exhaust, Uprev, GTR, Injectors, and Fuel pump.
Here's my Dyno. http://specialtyz.com/blog/?p=2496

Thanks

 

WOW! You answered all my questions already. Just under 400rwhp at 11psi? Not bad for a car with stock cats.
With my SG Motorsport longtubes I will hopefully match or beat that.

I don't have the tubing even unpackaged at this point and my Lexus is in the garage for finishing touches so the Z won't get love until the late fall or winter. Ill see if I can snap some photos of the intake tubing today but I'm not sure how much it will help uninstalled.

 

Thanks.. no rush, but Ill be able to tell how it routes. I think the new kit has a way better bracket than mine as mine is really close to the shock tower.. No real room for the intake. I've seen some pics where the intake is where the Brake MC is. I wonder if thats how they did this kit? Right now i have a heat shield for the headers and i run Air from the front to the heat shield to get cool air in as the filter is right above the headers.

Thanks

 

The air intake (filter) is ran to the front bumper area, just in front of the wheel well & right below the crash bar. Got the install manual but cannot copy & paste photos from it. Much better location than the V1 kit imo. With some silicone connectors & pipe, you could re-route the intake for the V1 kit.

Nice #'s & looks great. Not to be a buzz kill but that is on a dynojet, so minus 10%.

Hey INTIMAZY, I found an idler pulley for sale that's near $600 but on the instructions it appears as though the idler pulley (There's 2) is included. Is it?

 

If you could put up a pic that would be awesome. I may actually get rid of the z though as i need room to fit my little one. I havent really touched it since she was born 2012 ish..

Not a numbers guy but I always thought the dyno's were
Dynopack + ~10%
Dynojet -0
Mustang - Reads ~ -12%

But the best is the butt dyno. that's the most accurate one that i go by..

 

Dynojet typically reads 10% higher, Mustang 10% under & I know nothing about dynopack. In the end, a dyno's just a tool for tuning but it's nice to know the accuracy, especially if you're pushing the limits on a stock block & trans.
Even so, the way the torque comes on early & the flat hp look better than a vortech/procharger might. Torque looks great on the 2nd chart but the flattened out hp looks better on the first chart. Looks like a little more work w/tuning & a larger fp &/or injectors might be causing a lack of fuel on the 2nd higher hp chart which might be why powers falling off before 5,500rpm OR the V1's limitations were hit & couldn't flow anymore air.
This may sound nuts, but I think you're better off with the first tune. Tq peaks 800 rpms earlier. Horsepower, while lower, peaks @ 4,500 rpms & stays there to redline whereas the higher hp tune peaks much later & quickly hits a rut. I'm sure it feels great either way.
Tell me crtan77, did you have to purchase an idler pulley separately w/your V1???

 

Hey onevqde, I believe in the end we changed the timing a bit to hit a bit less than the peak HP to get the better peaks as you had mentioned. I did t have to buy any pulley as this was a complete prototype. I do believe that i have a 110 pulley in the garage though if anyone needs it. Also if you guys are looking for parts, this is the only HKS shop i knew before HKS came back to the US. https://store.activeautowerke.com/co...charger?page=2 maybe check with them if they have the pulleys you needed.

 

Cool that the shop u went to put this together. Forgot u bought the prototype, so u got the whole deal. Nice.
Pretty sure the 100/110 mm pulley w/belt is the only thing outside of fuel components & mngmnt that's separate but not sure & not sure that I care anymore.
Just read over the install instructions for the Vortech which was right on their website as it should be. Nothing special & very straight forward. Call'em & they answer all questions. I like the rotrex type supercharger but will probably go w/Vortech.

 

I bought the kit from someone who was there when HKS was leaving the US. It was on their demo car at the time. I did the install my self.. without much instructions I borrowed the other kit's is install pdf and just improvised the rest. It was pretty straight forward, not too much you could mess up My buddy had the vortech, thats nice too.

 

I finally got around to starting the installation on the HKS V2 kit. Overall it was pretty easy and straight forward with the provided instructions, and took me a few hours to get the bracket mounted up, supercharger installed and plumbed as much as I could without it being in the vehicle to finish plumbing to the provided intercooler and traction fluid cooler.

Originally I had planned to put it on a built motor, but things changed a bit so I'll be putting it on a stock DE motor with some OEM VR38 injectors and getting it tuned on low boost to see how it fares initially, and then hopefully in a few months I can get the machine work done and install the pistons/rods I have in a spare block and raise the boost with some newer/larger injectors.

 

Hey AKS. Looking good. You using the 100 or 110mm pulley?
Funny how plans change. I came sooo close to buying the vortech and whatnots from you. I decided to go the 4" intake route instead and build on that. Once I found that my obese FX35 running mid 15's stock was in the low 14's after the 4" and various other mods, I changed my plans. Now it's in the high 13's but for much less $ and headaches. Maybe Enjuku carries n2o.

 

I've got the smaller high boost pulley right now but I will probably be purchasing the low boost pulley as plans changed a bit and I wont be running it on the built bottom end right away.

I will most likely run that stock motor on low boost, possibly port the spare intake manifold, see what gains that delivers with the supercharger, then perhaps modify that and utilize a larger 90mm throttle, then once I've squeezed out a good bit of power and get the built bottom end together, swap it out and put the high boost pulley in and see what she can do.

 

Stoked to see someone installing this V2 kit! I did a bunch of reading trying to decide which pulley I would want when I pull the trigger on this kit.

Per that chart HKS posts, even with the 100mm it looks like it would be well within range for a stock block. Chart (showing measured at engine) is about 493hp/409ftlb. Minus your average 15% loss, we're looking at 419whp/347wtq.

I've seen plenty of vortech equipped stock block DEs running numbers well over that at the wheels without issues.

Got any thoughts on this? I've seen Z1 tune some stock block DEs on a supercharger (much more gentle torque vs. turbo) up around 450+whp/400ish wtq without issues.

Pumped to see your results!

 

Yea, I've seen stock block DE's make pretty decent power boosted, but I am going to just err on the side of caution initially and run the low boost pulley. Plus I am curious what we can do on the lower boost setting while modifying some other components (TB, intake manifold, headers, etc.)

The other thing is, this car will be 100% track used, so the motors entire life it will be getting the snot beat out of it, so I figure being a bit on the safe side isnt a bad idea. Once I get the spare motor built I'll put the other pulley on and see what she does, that way worst case a rod shoots out the block, I already will have a backup ready to go in.

I'll keep you guys posted as I make progress. I just got my VR38 injectors in, and my new radiator and water pump setup, so hopefully in the next few weeks I'll have it all fit, plumbed, and off to the dyno for some initial results.

 

Definitely be sure to post your results!

Being cautious is the way to go for sure. I'm definitely curious because I have pretty much all other mods completed, sans a built block.

Currently running tomei 272 cams, tomei springs, nismo oil pump, kinetix velocity, nwp throttle body, momentum headers, GT-R injectors and a walbro 255 pump. Plenty of other cooling mods as well to support.

My goals are right around 425whp and a safe torque level, so your experience and numbers will definitely play a big role on the route I go.

 

Keep posting updates please!
