Great news, our production Steam STX 67+ turbos for Subaru WRX STI are in stock! The preorders have already started shipping, so you should see your turbos soon.
In case you were wondering, they are similar to our standard Steam STX 67 turbos, except the plus model has the next larger turbine. The should both be 350-400 whp turbos. The plus model might be a better fit for your car than the standard 67 if your car is more built, has a 2.5l motor, or otherwise is higher flowing.
Tuners strongly recommend them; we recommend them. Now we make them: Introducing the SteamSpeed BCS (boost control solenoid aka EBCS) plug and play for all turbocharged Subaru models.
Our 3-port boost control solenoid provides super high resolution boost control to dial in much more accurate tunes vs. the old OEM 2-port solenoid. Our BCS provides your tuner the tool need to safely dial in the correct boost levels, and achieve the best results possible. At the heart of our BCS is a super reliable industrial valve that is more responsive, higher flowing, more durable than stock. With our high performance BCS valve, your turbo will spool quicker, and maintain the tightest possible boost curve.
We include everything you need in the box for plug and play install. It mounts right to the stock location without modification with our custom made brackets, and clips right into the wiring harness. We even include new silicon vacuum lines and bolts so no extra trips to the parts store is needed.
Installation is a snap. Our BCS can be installed in 15 min with basic tools by most everyone.
We have used the GrimmSpeed BCS on our cars in the past, and they have worked great. Tuners we have worked with in the past recommend them, so we used their product as a measuring stick.
For our test, we simply swapped out the GrimmSpeed BCS and hooked in the vacuum lines in the exact same ports and swapped their connector for ours into the wiring harness.
How did it work out? Not surprisingly, they worked basically the same since they both are based off of nearly identical MAC industrial valves. In our testing, our higher flow barb option did out flow the GrimmSpeed BCS by about 20%. Our standard barb option flowed exactly the same. In fact, in our testing, the boost curves were identical with both BCS.
This is how our EBCS was hooked up to the waste gate.
Introducing the Steam STX 71 with stock Lecgacy GT and WRX 08-14. There aren’t as many options out there for the LGT guys, and none come to mind that make make STX 71 power. Our customers have been asking us for a while, when will you make a STX 71 for in stock LGT fitment?
Well, here it is!
This turbo has the same 11-blade GTX3071R spec billet compressor wheel and TD06SL2 9-blade turbine as our STI model, but now with housings and lines for stock LGT fitment.
We are looking forward to the first LGT or WRX 08-14 guys to make 400-450 whp with a stock style turbo.
