We are working with wbradley to get him the parts he needs to get back up and running, but it's not a warranty claim.

If you purchase the kit from an authorized retailer in North America, and it is installed correctly, there should not be any problems.

No offense - as I am a huge HKS fan and have half your catalog including the Supercharger on my 86 - but your network setup at least here in Canada is severely skewed. I didn't purchase through an authorized dealer because the ONLY authorized dealer was too busy to offer any help or even provide a quote. They've burned enough bridges with local people that most try to go elsewhere or choose another brand.

I basically knew I was walking into a "no warranty" situation but I believe in the product enough to try it. What I am saying is - if there is a real pattern of failures in a part it would be very diligent to go above simply telling people that it's their fault for not buying through a certain retailer.

Once again - my car is a rolling billboard for HKS, literally. I thankfully have not had any issues and all of my installation has been professionally done. However if a part fails because of a glaringly obvious defect in the future I HOPE you guys will at least approach it with an open mind.

Hope it helps. The only photo of the pulley I took. I did not notice any part in the unit with the 5 bolts mounting pattern.

i was told you can not upgrade V2 pulley?

If I would only know that! At this stage I'm not thinking about upgrading the pulley, I just want my car running again

Why not? It's the exact same blower as the V1. They sell all different sized pulleys for this unit.

they aren't the same pulley and i confirmed with evasive that the V1 is the only kit you can upgrade pulleys.

my kit is finally finished running on e77 currently. no dyno numbers, just a street tune. but definitely 300+ whp still havent tuned the 95mm pulley

What's different about the pulley? Mine (V1) attaches with 5 bolts and I have been given assurance that the replacement I have on order will fit my existing pulley from Scott at HKS USA. The replacement will be new production, a V2 no doubt and I was paranoid after 16 weeks down time when I finally receive the replacement that the pulley wouldn't fit. I asked on this thread for people with V2 units to check if the pulley was a 5 bolt attachment but nobody responded.

that's not true @Efferalgan said

I take it the V1 uses 5 smaller bolts while the V2 uses 1 larger bolt? Doesn't seem there are many people with this kit let us know what you find out

According to Scott @ HKS USA that's not the way they are, those units in Russia might have been different for some unknown reason. So, I wanted to find out from others that bought the kit from their regional sales network vs. grey market.

i specifically bought the V1 kit over the V2 because the pulleys can not be upgraded yet. if you have the V1 kit and convert it to a V2 maybe you then you can bounce between pulleys.

my decision was based off this...

V1 made less power than V2 on stock pulleys. but V1 can get more power with fuel upgrades and a pulley by a tone. so i went with the V1 kit. this is all per evasive motor sports. i believe they have a lot of knowledge on these kits because they were the exclusive tuners for the V2 kit in R&D.

P.S. V1 has 5 small bolts to mount the pulley i can take pics if need be

As I am aware. I want to to know how the V2 kit pulley attaches to confirm compatibility to my V1 pulley when I receive my replacement supercharger.

So far I have yet to receive confirmation other than by HKS and somehow still concerned I will receive the replacement only to discover a 1 bolt center mount for the pulley.

[Andew727]

hoping to have some solutions on the HKS s type oil cooler set up in front of the right hand front wheel. i noticed my turn signal has dented in the cooling fins and is shorting my light system. what has been everyones solution that has encountered this problem?

HKS doesn't offer their S/C pulleys any other way. Doesn't matter if we're talking about the FR-S V1, V2, or V3, S2000, CRZ, 350Z - they ALL use the same 5-bolt pulleys.

The differences between the V1 and V2 kits are minimal; the V1 kit used the 7040 s/c and the V2 kit uses the 7040L - same blower, same output, but rotation and orientation is reversed for better packaging on the V2. The inlet pipe on the V1 kit has a choked-down 90 degree turn right before the throttle body which isn't ideal. The packaging of the V2 kit allowed a straight shot into the throttle body for a little better performance. V1 > V2 upgrade? Because the s/c is mounted in a different location, the V1 / V2 S/C mounting brackets are very different. Also due to the different s/c location, almost all the piping (intake & intercooler) is different. So it could be done, but the only original V1 part you'd have left is the intercooler itself. Everything else would have to be replaced. And just to be crystal clear - both versions use the same 5-bolt pulleys.

V2 and V3 are very similar, V3 is just optimized to a whole different level. Most of the parts are the same between the kits (and there will be a very affordable V2 > V3 upgrade kit offered), the biggest difference between the two is the blower strategy. With the V3, we've actually slowed the blower down to flow more air with less pressure and less heat. Thus allowing for more aggressive ignition timing strategies, and thus, more horsepower. All the V3 details will be released (here) very soon. And yes, the V3 still uses the same 5-bolt pulleys
