Ya the only two headers I like I can't use. Sucks to suck.

If nameless and the JDL EL don't fit, I imagine the p&l and fa20club EL won't fit either.

This.

And how did you get this kit to 330 whp? :)

E85 tune, largely unfinished. You'll see it soon from @DeliciousTuning however :) we fixed a small issue we were having and I think there's a bit more headroom yet with no other mods.

Edit: The unfinished 330whp we were at was actually on E60. We should have even more headroom on E85.

KW mentioned sometime ago they were working in a header for their sc? Been quiet on that but hopefully they'll make something that gives good gains.

What that means is a skunk 2 header. You can bet it'll be a better bet to go JDL UEL or otherwise

Installed the kit this weekend
 

I spent my time weekend installing the KW kit and I'm happy to say I'm just about done. I just need to put the bumper back on and go for a test drive (hopefully tomorrow). Programming the ECU with the off-the-shelf factory ECUtek tune was really easy. Overall, as others has indicated on this tread, the install was relatively straight-forward.

Some things to note & lessons learned for future installers of this kit:
1.) Quality is top notch of all parts. Only thing wrong with my kit was I was provided a smaller clamp (1-1.5") instead of the required 2" clamp so I had to get one from my friend (this is used on the output side of the Rotrex C30-94 S/C).
2.) Included instructions leave something to be desired. Providing the socket size and actual factory torque specs would have been useful. Additional photos would have been useful. As stated before above, the oil reservoir, filter, and cooler instructions are pretty bad. Definitely connect and orient the hoses prior to installing the reservoir & the filter.
3.) The crank pulley requires you to be in 6th gear to loosen. It required a 22mm socket (which strangely was not included/skipped from my tool set) and a bit of muscle pulling onto a spongy-feeling resistance. Factory torque spec (after installing the KW SC pulley adapter) is supposed to be somewhere between 94 fl/lbs and 125 ft/lbs.
4.) It took me a bit of time to figure out my hot side intercooler piping was flipped around. Make sure you pay careful attention to this (perhaps some airflow arrows would have helped idiots like me).
5.) In hindsight and looking at some other installs, it would be highly recommended that the two banjo's and washers be installed on the Rotrex prior to the Rotrex going onto the plate. Just be careful not to get anything in the S/C. The yellow oil plugs for the Rotrex C30-94 supercharger were very difficult to remove once it has already been installed onto the plate. I had a couple "oh shit" moments dealing with both plug tops getting ripped off & having to unscrew the rest just by the plastic barrels of the plugs themselves.
6.) Engine oil cooler clearance does look to be extremely tight. It does not look as if the Forester/OEM oil warmer/cooler would work without at least modifying the idler pulley bolt that juts in the space right above where the engine oil cooler is (see 8th photo below).
7.) The crank case breather tube routing to the intake would have been cleaner if they included a straight adapter instead of relying on the factory L-adapter. I will likely take of this myself in the near future (easy).
8.) It was a bit unnerving & difficult to cut through the factory brake booster hose (maybe cause I didn't have the best knife) because the instructions were not very clear. Once you install the vacuum "T" in place, run that vacuum line to the bypass valve.
9.) Although I did a lot of the install myself, it definitely helps to have another person around for several steps (ie installation of the plate onto the engine, routing of piping, etc.).

Your going to love it!!!:burnrubber:

This. One of those f*cking plugs sheared off on me and I had to use pliers to work it out. I was terrified a chunk would come off and fall into the Rotrex.

Congrats on the kit and install , ur going to love it , with a good tune u should see some good numbers , I was able to get 296 whp 235 Tq , . Only thing I am getting use to is the Supercharger whine lol ....

Yeah I don't know either, I have the agency power header and a dc sports overpipe. I'm not seeing where the fitment issues would be....it's on the bottom of the engine...

may the schwartz be with you....

Thanks! What kind of supporting mods & what kind of gas were you on when you got 296whp/235tq? Did you start with the KW factory tune and if you did what was that HP/TQ baseline? Who is tuning your car?

I am in Canada gas was pump 94 , no Kw base tune was tuned by Onpoint dyno in Toronto , Greddy evo3 exhuast , borla uel header , Misimoto rad ,

Some EL headers turn up into the engine bay right in front of the crank pulley.

All the headers I mentioned are long tubes that have primaries coming up into the engine bay. That is why they don't fit; the bracket for the supercharger is in the way, as well as the additional crank pulley. Every other header is fine because none of the others go up into the bay like that.

I can't give a definite time on when it will be, but I plan to get this kit and do whatever I Can to keep my forester oil cooler installed

Is there anyway you can take a photo of the Forester oil cooler with a tape measure in the background 1.) first measuring the height of the unit and then 2) another photo measuring the diameter (is it larger than the base of the stock seat?).

So i put all my engine carbon fiber back on with the supercharger!!

So I finally put on the bumper and drove the car for the first time with the SC installed. Did anybody have any bumper fitment issues? It seems like the FRS grill (not the two air duct things on the side which I removed) is right up against the IC and I'm as much as 1/4 inch off a good number of fasteners underneath the car. Kind of annoying.

Anyway, for the drive. First thing I noticed was the whine. It is quite loud and while cool sounding I'm pretty sure I'll be looking into the clogged idler, smooth belt, or whatever it would be that makes that noise a little less obtrusive. Not sure if it is the factory KW tune that is to be blamed or is it that I just need to relearn how to drive with a SC installed, but it isn't very smooth on initial take off in 1st. I've played around with different amounts of throttle but still it is rather hurky-jerky. Feels like the bog feel with a giant air conditioner on full blast in a small displacement engine but about a magnitude worse. But once it is past about 3000 RPM up to redline WOW is it fun. Not sure how many HP my buttdyno is registering but here is a significant amount of power there and it just keeps climbing. The bypass sound is also very cool sounding yet subtle. Didn't want to push it too hard since it was my first drive.

So is anybody else still on the KW factory tune?

If you get a custom tune your tuner should be able to make it much more smooth in the lower range. Mine feels great all the way through the gears.

Can you guys elaborate the benefits of the front pipe, over pipe with KW kit and catback exhaust if any?

I've searched but couldn't find the exact answers. From my previous experience with other boosted cars (2 Stis and Evo X) as well as the Corvettes ..catbacks never really made a big difference in terms of power..and IIRC, someone was mentioned that the headers don't make big difference either (until 6500 rpm)..

I was hoping to be able to use the Forester oem oil cooler when I get this kit but it seems like the clearance might be an issue also.. hopefully the new KW oil cooler kit solves this problem since I have no intent to spend $600 for a simple oil cooler

I'm on it.

Absolutely doesn't have oem smoothness. But it doesn't surge a ton, most of the time it's smooth, just not 100% of the time.

Noticed a bit of bogging at first. Didn't take long to get used to.

mit_peid's photo of the KW install suggests to me Forester oil cooler will fit. Looks like KW pulley mounting bolt is a little lower than the oil filler cap and won't interfere with the cup at the top of the oil cooler.

@gmsii, @KraftWerks

Is this known issue? BRZ any different?

I have bumper fitment issues, hoping to fix that soon :P Too lazy to track down the source for now

The FRS does need some trimming of the grill, we are making revisions to the instructions to add more detail, torque specs, revised oil hose routing etc based on the feedback received here on FT86club. We hear you guys loud and clear and we're working on it! :thumbup:

I had fitment issues as well,I had planned on doing a good right up for them, as I have already been talking to then about fitment. Mine for the most part settled in after I removed the bumper the second time. I had really bad gaps at the bottom of the headlights. I have planned to remove the mesh and install some extruded steel in its place. I believe that would give the needed clearance. I will have to cut the mesh though to retain the solid part at top to cover the bumper underneath. We will see what can be done.

may the schwartz be with you....

Should be installing the KW/S2 engine oil cooler this weekend if everything lines up. I'll take detailed pics when I get it. However, keep in mind it is not going to be the full production kit. It'll likely be near exact though. :)

You mentioned the frs specifically, so does it mean that the brz does not require said trimming?

My grill / bumper is on without trimming. But it did take a bit of effort to get the plugs lined up

Well why don't you just rub it in everyone's faces :P

Well so is mine but there is a slight gap between the edges by the wheel well and side makers. There always was but it's about a 1/16 more then before.

may the schwartz be with you....

Same here

Well crap, finally got my oil today and after adding a bit to make sure i was full. I start it up and of coarse i wasn't low at all.... Now im over filled... Oh well guess i will get the vacum pump out tomorrow and remove some. Got the leak fixed though so thumbs up on that. I always have weirdest bad luck.

Each time I check the unicorn piss (aka Rotrex oil/fluid) it seems to be on the top end of the dip stick closer to the max level. I have about two inches left in the bottle. Didn't shorten any of the hoses provided with the kit so I'm thinking it should hold capacity? Where was your leak at?
