Lol

Ya... 86 is a pretty kick butt car stock. I can only imagine how well it would be with decent pickup.

And what are the specs of that S2k? Wondering, because if it's similar in power to a JRSC 86, then maybe the 86 would've been similar to that s2k, in regards to having a hard time catching them on the straights too.

Seems like you guys are highly experienced drivers with slower machines, while the Porsches and Mustang either can't drive their cars as well, or the cars couldn't handle as well as the 86, or maybe a combo of both.

I wonder how it would've went with a bit more power (JRSC)?

That video was on (terrible) BFG Rivals... I would have been able to keep up with Jeff with RS3s on.

This is the SpeedVentures Advanced/Open Passing group, aka the wild west, at 86 Fest 2.

[CSG David]

Oh yea I forgot about those Rivals. I blocked those tires out of my head because they were terrible...

Auto Club Speedway favors power. The JRSC will pull on the S2k with the JR engine oil cooler and complete CARB setup (factory emissions in place).

I believe Kraftwerks kit's CARB certification is also pending and will be ready soon..
FYI, I have been also tracking my Kraftwerks powered BRZ and happy with it so far ( you can take a look at my build thread for more info and vids) .. as others mentioned when a belt snaps it's really nice to be able to drive back home with the KW kit.. the last thing I want would be towing my car from Oregon to Seattle (ORP) ..but other than that JR and KW kits are pretty similar and you can't go wrong with either I think.. KW also has a price advantage if the group buy is still going..

Here is my contribution of the BRZ/FRS vs GT3RS.. in the first video my BRZ was completely stock except tires and in the second video you will see how the additional power lets me pass the GT3RS easily, pay a close attention you will hear the guy is actually flooring (revving to the sky) on the straightaway after giving me a point by (not sure if he was pissed or something) .. by the time I passed the guy I was almost half way of the straightaway ..

...don't get me wrong, I don't want to give you a wrong impression by saying " my BRZ is now faster than a GT3RS" or "I'm a superior driver"... It's probably because the driver was either slow or not pushing his car.. but you can use the first video as a benchmark to see the actual gains since it's the same car, same driver so that you can see what really adds.. coincidentally , same exact car and driver in front of me at two different days (before and after the SC kit) so it's a good comparison purposes

and with Kraftwerks kit

later on I was able to improve my time by a full second with shitty tires and am hoping I can cut another 2-3 seconds with the new tires (Z214s)

one important thing to mention in the first couple videos GT3RS had the head start so it's even harder to make up for the power advantage as opposed to joining the track afterwards

Awesome vids everyone.

But you guys are funny hahaha....I only asked for Cayman S or base 911's lol.... But props for holding your own against an even greater Porsche, the GT3.

CSG...so you hate Rivals? I know RS3 is a fave within track enthusiasts for almost all model cars...but you ever use ZII or Star Specs? Like em?

We've used many (most) different street tires and R-comps. Slicks are a different territory and not something that's often used amongst the Socal community. We'll recommend what we would use on our car and our personal cars.

you know the fact that you can fit an extra set of wheels and tires in our cars, right?

You really should come out to an 86CUP event and just chat with us in person. You'll get a lot more done than asking questions across 10 different threads

Not many shops religiously test the products they sell, and are transparent about their setup.

Ya..R comps ...bUt dEm shItZ iZ XpenZiV yO

@glamcem:
I just read ur build thread. Very nice.

274whp with a 168whp baseline is super impressive! That's like 326hp at the crank if I'm not mistaken. With stock headers too?? Sh!t that's good.

I read you used moto in the east coast for tuning. Why didn't you just go to drift office for tuning since you're in WA? Either way..274 is dang good..specially on stock headers and low psi still.

not really, NT01s are pretty cheap and definitely a lot better tires you that the ones you mentioned earlier.. you have to keep in mind, you can easily overheat the street tires at the track which may cost you another set of tires, so R comps may cost even less in some cases such as the tires with 80 and above treadwear rating

I had a previous experience with Mike from Moto-East when I had my Miata and since I already purchased my previous tune and the Ecutek license from him,he gave me a really good deal on my 2nd tune and the new Ecutek license .. Bob, is really helpful and one of the best tuners you can every work with in my opinion so he was pretty busy at that time and I wanted to attend a few events in the same month I received my Kraftwerks kit

also, unlike many people, I don't have problem with e-tunes since I believe it's somewhat easier and beneficial for doing the revisions after the track days based on the logs, issues you may have experience ..I also took my car to the Drift Office for a dyno session and sent my tuner some logs taken at the dyno so thanks to Bob for the help and valuable advice

1. Which is the best (I know this can be subjective) CARB legal SC kit out there?

Is Jackson and Innovate the only CARB legal SC (or even turbo) kits available currently? I see they are two different types - centrifugal turbine and twin screw. Jackson seems much more attractive, especially since I’ve seen them around since the 90s.

My goal: 300whp DD and monthly track toy. But I’ll settle for 280ish whp. And, whatever is on par with a stock Cayman S (320bhp) or base 996(300bhp) at the wheels …which I assume those Porsches will be well below 300 to the wheels, correct?

I’m NOT looking into making a 400-600whp super drift/drag magazine monster. I just want a decent amount of reliable sportscar power.

Has anyone tested and reviewed the JR kit? Any 3rd party dynos?

How much extra weight will this kit add? I hope not +100lbs.

What’s the difference between this snail and the one in the HKS or other similar SC kits?



2. Reliability and bottom end rebuild:

Will running this SC kit on the stock bottom end be a big concern? Sounds like it, especially with the super high CR.

Has there been a couple cases of people blowing their stock engines easily with a mildly boosted SC or Turbo kit? If yes, what is the ratio of blown:not-blown among FI kit users and owners?

Like already mentioned, my main goal is to make this reliable; as OEM reliable as possible. I’m not rich, so an engine rebuild will not come quickly after a big purchase like a $5k SC kit, so it would most likely come in the relatively distant future; but, I would like to get it done sooner or later.

Also, a budget rebuild is preferable and I don’t need to make it a 600whp capable monster - just 300whp is sufficient. So idk if I should have the entire thing rebuilt (valvetrain, cams, special sleeves and specialized crankshaft, etc.), or just the primary concerns dealt with and maybe only doing a few things to the lower end - lowering CR with pistons primarily, maybe diff rods, and that’s about it.

Will only replacing the pistons (lower CR pistons) and maybe upgraded rods be sufficient enough? …rebuilding just the bottom end and leaving the heads and valvetrain alone, for lower costs.

How much would a simple lower end block rebuild like that cost?

Any recommended shops in SoCal that can pluck the FA and rebuild it (or, send the block off for rebuilding)?



3. Cayman S / base 996 Killer?:

I think an 86 + a JR kit will be a very nice (and emissions legal) option, instead of and if you can’t afford a used Cayman S or old 911. What do you think?

…of course, I mean with upgraded coilovers, suspension bits and tuning, wheels/tires, brakes.

Has anyone driven or owned a Cayman or 911 and also a mildly FI’ed 86 on the track to compare the two?

I assume the 86 would have an advantage once SC’ed and bringing it to the same power levels as the Cayman, being it would be around 200lbs lighter. Obviously the Porsche has an advantage for its’ famous superior and refined handling…but the 86, being 200lbs lighter, might have a bigger advantage. Idk.

I have a Cayman S, an NA DD track build BRZ, and have ran the Cayman and the BRZ at Miller Motorsports Park with a JR Track build DD BRZ. Are you in the U.S.?
