Did you dyno the car that way? I've been searching for results with the standard pulley and ace header.

Placed my order for the JRSC kit with dual catch cans and Jackson oil cooler. Can't wait!

Are catch cans common with the JRSC kit?

They're not needed but since I will be tracking the car and daily driving it, any sort of preventative maintenance is accepted here. I'd rather open an empty catch can than an oily intake pipe.

I was doing research on this and came to the conclusion that it was not needed. I only have the oil cooler.

I've had the JSRC since 11/2016 and it is my DD. I don't seem to lose any oil.

Oil loss is not a symptom of needing a catch can. If you take off the intake elbow for the supercharger intake and there is oil residue there a catch can is a good idea.

As it is your DD you may not need one but you may want to check anyway

Hi guys, just sharing some recent experiences.
I have a 2016 BRZ with the C30 supercharger. The SC was installed around 4000 miles and I now have about 11,000 miles on the car. The car has gone through roughly one season of 86CUP track days. Car is basically in CARB legal configuration with a Greddy axle back muffler.

After one of the morning track sessions last weekend, the car sounded horrible with a loud exhaust leak. No check engine lights, but we could tell the leak was coming from the header area. We took the car to a lift and removed the header and heat shields. This is what we found:


At the time my SC was installed my shop noted that the OEM catted header would trap a lot of heat. I also ran a vented hood in the summer months after seeing very high under hood and oil/coolant temps. The takeaway for me is that the OEM header isn't meant to take this kind of heat. I am running a OEM replacement for now but will be looking at uncatted aftermarket headers to address this.

Wow, first time I've seen this. I'm running a C38/CARB tune and TRD axleback. Wondering if something like this may be in my future. Has this happened to anyone else?

So if you go with aftermarket header you will no longer be CARB legal, and you will have to take it somewhere to get tuned. Correct?

I think CSG Mike ran into this a while back - probably more of an issue with people who run their cars hard & frequently at the track. That said, this is obvious evidence that the catted stock header is a significant restriction on a FA20 with FI.

Correct. This was an upgrade path that I wanted to avoid, or at least postpone, due to the additional costs/mods and the slippery slope that entails. But I track, and that obviously has a steeper toll on components than a purely street-driven car would face. Chalk this one up to the "you gotta pay-to-play" column.
If your car is never or rarely tracked, this may not ever be a concern for you.

I wonder if you would have fared okif you had just gutted the cat on the stock header.

[10Tim]

I do SoCal 86Cup and track my car so this is not good news. Maybe I should keep my eyes out for stock headers in the for sale section and just plan to replace when this eventually happens, because I want to keep my car CARB legal.

I heard someone say that a gutted stock header actually performs fairly close to an aftermarket header... but in the same vein, it may require a retune. If you're going that route, you might as well buy a header, in my mind.

yeah I thought about this route as well. Stock headers shouldn't be too hard to find, I know a few local shops who have spares on hand from doing header swaps for their customers.

It has happened to a few 86CUP competitors with factory header. You can still blow out the cat or HFC in the header on track.

OEM header and front pipe had blown out cats on a completely factory vehicle.

It's not a concern on a street car.

It will be a wear item as you increase your pace.

Gutting the cat is basically removing a source of restriction. Properly designed headers help scavenge exhaust gasses properly. Not all headers are designed with the same level of intent. While it does improve power output, we have proven that various headers do make different power for a JRSC setup.
