Maybe Kinugawa will do a ballbearing Garrett CHRA.

I'm always skeptical of the bargain bin turbos, as they usually don't perform as well as the top shelf turbos. But if someone wants to try it, I look forward to seeing results.

Ditto here. The Garrett BB cartridge that Blouch uses is better reliability wise though and that's what you are paying for. For $890 though, the Kinugawa is definitely interesting. Who's going to be the Guinea Pig? |

Hey guys looks like there was an update on Scooby Clinic about the new Twin Scroll Exhaust housings. Here is what Kev showed
Hi, check out these bad boys. At last the new range of SC billet TWIN SCROLLS have arrived with their new custom cast exhaust housing. These are true twin scrolls not twin entry, the real deal. pictured here left to right SC36, SC42 and SC50 Billet TWIN SCROLLS. Let the testing begin cheers Kev |

Based on what I can tell and especially since SC has now released an SC50 Twin Scroll. I would have to say that these turbo's are *approximately* compared to these from Blouch (this is only an educated guess, no hard facts)
SC36 TS = Blouch 16G-XTR; SC42 TS = Blouch 18G-XTR; SC46 TS = Blouch 20G-XTR; SC50 TS = Blouch Dom 1.5XTR |

The only concern I have though, is that there have been some reports of people experiencing a bit more lag than they expected, but overall the power is there and is comparable to the top shelf turbos in that department. I also saw a couple posts from Vlad about porting the wastegate bore to nozzle interface for better boost control. If you've got more time than money, and have the tools to do it, I think it's worth the effort. If money is no object, then get what works out of the box. It would be very nice if Blouch had a 10cm TS exhaust housing that enables a 60mm turbine to be used. I think you'd get very comparable results to a full rotated GT3076R (with a .82 hotside) out of a stock location twin scroll provided you use a 3" inlet. |

I too, am very interested to hear more about the SC50. BTW, did you ever get your setup running and tuned, I think there's quite a few of us that are waiting to hear about it. |

You may want to read it. How Garret was acquired by a different company, how the outsourcing to China happened, how the personell in US was reduced but profit maximized, etc. Bargain bin is... quite a flexible concept and many turbo assemblers reach into it, one way or another... Castings are made in China, Mitsubishi may even assemble their stuff there. As far as performance, look at the 18gXT thread. These have been arround for a while now in the single scroll version. Compare them with the regular 18g, people have been doing this. This is similar with the HTA line, that has begun quite a long time ago. New aero, billet compressors, more flow. But not a new standard for performance. Look at the 18gXTR thread, in the single scroll. Cobb tested that against the 18gxt in a 2.0 EJ205. The full spool point is the same for both, the R version provides more area under the curve, that's all. By the way, for both, they were fully spooled by 4100RPM. Not something that nobody else can ever reach.... |

I've also been asking Bryan @ BnR Supercars if he would take his magic with the VF single scroll turbos and try to apply it to the twin scroll crowd. He attempted once in the past without success due to the turbine size limitations of the P25 turbine housing. If more people asked about T/S options he might be persuaded to give it another try. Can you post cross-forum threads on NASIOC or is it against the rules somewhere? The thread is on the Legacy GT forums.

Looks like the New Blouch Twin Scroll Housing was made a little larger to accommodate a larger Turbine, per Kev @ ScoobyClinic. Looks like the new SC50 Twin Scroll is probably an actual Dom 2.5XTR now.

ScoobyClinic just tested the new SC36 Billet Twin Scroll Turbo using the new Casted Exhausted Housing.
Link: SC36 Billet Twin Scroll Dyno Pretty impressive as it net 403bhp on 20% Meth and Full Spool around 3500rpm on the Dyno. |

I have been using a kinugawa ts from when they first came out, td05 20g p25 housing, same as they are selling now, no problems what so ever and sure performs well, i also have a vf36 with a 20g wheel in it, i have had both turbos on the car the only difference being part throttle spool with the ball bearing turbo, a bit more responsive. I also have an sr50 twin scroll using modified kinugawa turbine housing, this combination was not as responsive as the other 2 mainly because of of bigger sr50 core but would be good for all out power.

So are we talking the equivalent of a 16g, 18g, 20g for the SC36, SC42, SC50 but in twinscroll and BB CHRA housings?

Oh, nice. Can't wait for some dyno plots on a 2.5 as well.

Blouch/SC46 converted from a VF37 hotside on a 2.5L EFI Logics Stage 1 block. I was hoping for more power, but was told by Chris that the hotside is what's holding it back. The car feels nice, smooth, and responsive. It has power, but is slower than unclematt's setup by a couple hundred RPM's down low (when comparing our dyno runs on EFI's site).

Not bad #'s though for only 22-20 PSI. Looks like a sweet ride! The new Blouch hotsides are larger so there may be an upgrade path for you there but the SC46 billet wheel is happy in the 25-26PSI range I thought? Or did Chris feel that the housing was choking flow and could not turn the boost up any higher due to surging/creep?
