If it's not broken, you don't need to fix it!

After enough research, I am going to be going with this instead of Innovate. Thanks.

Fantastic choice!

So a buddy of mine had a C30 JR kit and the unit went kaput. He's giving me the rest of the kit since he went the JDL rout and all I need is the SC unit. Instead of going with the C30 I was going to upgrade to the C38 but then I saw this pre order for a C38R at a fraction of the cost. Can anyone tell me more about this? Also any word on a variable supercharger unit like the rotrex VC8 so we can get more low end output out of these centrifugal sc's?

Oh, maybe just a bit on the cons side, it is a little more tiring to control the boosted car in snow ... maybe because I only had four-season tires

which oil cooler are you running and do you have problems hitting operating temps during the winter months?

The C38R is not available for a FA20 application. PM to order a C30 or C38.

What’s the difference between C30 and C38? Neither of them supports 2017 model yet correct?

Both fit on the 2017 BRZ.

C38 has more theoretical overhead than a C30 for big power.

I hadn't heard of this before but just looked it up. Is there a reason it wouldn't work on the FA20 if it is the same size as the C38? Does it have to do with the belt or power levels?

gtengr · 03-28-2018, 10:18 AM

I think it's mostly the power levels. Rotrex is marketing the C38R's ability to support +900hp. That would probably put it in an inefficient operating range with most FA20 builds.

I have installed OEM Subaru STI liquid-to-liquid oil cooler. It actually helps with warming up the oil quicker in the winter and then helps with keeping the oil temp at the coolant level. It is more like oil temperature regulator than cooler alone. I would recommend Jackson Racing Dual Radiator/Oil Cooler which is a more powerful liquid-to-liquid cooler. Air-to-liquid coolers are better for track and warm climate areas.

Hey i got a hks bov that i plan on installing on the kit. I was wondering if it would make a difference whether i install it before or after the maf sensor? I marked x’s on the picture, a being before and b being after. I was planning on putting it on b but didnt know if it would interfere with the mad sensor or if both will mess with the maf sensor. Thanks!

rns294 · 03-30-2018, 02:45 PM

Neither because if you are going to use a BOV, it would replace the existing bypass valve.
