Decided to start a new thread for everyone to discuss the different options for stock location twin scroll turbos. Many of us have been following the Blouch thread, Moore Performance etc, and it wouldn't have been appropriate for me to hijack their threads with discussions of competing products, which brings us here.

I haven't seen a thread dedicated to discussion on all the brands, so this one will cover any info found of each along with prices and hopefully first hand results to compare. Hopefully this will help those that are looking into twin scroll to know what their options are while saving them time.

Here's the list I've come up with so far.



Litchfield turbos
"LM400 (HP rating) – S (Exhaust housing size S=small L=large) 60 (Compressor cover size)

Examples of popular Turbo combinations:

The LM400-S60 turbo is rated for around 400bhp with near standard spool up characteristics. This Turbo is designed to run on the 2.0litre STI engines and uses the smaller internal volute in order to maximize boost response. The turbo uses the 0.60 Compressor cover with the 58mm intake. This is the same spec of turbo we ran on our 2009 Type-20.

The LM450-S60 turbo is rate for around 450bhp with peak boost arriving 500-700rpm later than the LM400. This Turbo is also designed to run on the 2.0litre engine and uses the smaller internal volute in order to maximize boost response. The turbo uses the 0.60 Compressor cover with the 58mm intake.

The LM450-L60 is the 2.5litre version which produces 450bhp and uses the larger internal volute which does not become overwhelmed by the larger engines exhaust gas flow. This turbo uses the 0.60 and offers instant throttle response and no lag making a superb street turbo."

They have recently announced that they have new billet wheels available, no pricing yet but many believe it to be the same. They also do thermal coating as standard.


Pricing range from $2,400-2600 without shipping/duties

Dyno Results

Thread on Scoobynet

Scoobyclinic (made by Blouch)

These turbos are custom spec for SC by Blouch and use Billet wheels.

SC42TS 420BHP No other details yet.

SC46TS 460BHP Believed to be 56.5mm Turbine 71mm Billet wheel, 7cm housing (possibly recently increased to 8cm or 10cm, 47lbs of flow)

SC50TS 500BHP. No exact details yet, most likely similar to the Blouch 3.0XT-R-TS

Dyno Results

SC46 twin scroll E85
SC46 twin scroll on meth
SC38 Twin scroll E85
VF37 vs SC46 TS both on E85

List of other SC turbo dyno graphs

Scoobynet thread. One thing to note is that they have a SC46/36/38/30 single scroll and a twin scroll, so make sure when you see a dyno figure for a SC46 that it is for the twin scroll.


1.5XT-R-TS: 47lb Ball Bearing Garrett CHRA 56.5mm Turbine, 71mm wheel.

2.5XT-R-TS (using VF37): 47lb Ball Bearing Garrett CHRA. 56.5mm Turbine with 71mm wheel. This is the same as the new 1.5XT-R-TS, but the 1.5 has slightly better volutes. This turbo is not listed on their site, but they will still make it.

2.5XT-R-TS (new housing): 49lb Ball Bearing Garrett CHRA. 60mm Turbine with 71mm wheel. This is not listed on the site, but they will make it. They recommend you just go with the 3.0XT-R-TS though.

3.0XT-R-TS: 55lb Ball Bearing Garrett CHRA. 60mm Turbine, 76mm wheel.

Turbo Blankets
The DEI T3 blanket will fit both the 1.5XT-R-TS and 2.5XT-R-TS

Dyno Results

Blouch 1.5XT-R-TS (V8 EJ207, 90 + meth)

Blouch 2.5XT-R-TS (I believe this is one of the old versions)

Blouch 1.5XT-R-TS on a 2.5 with 8cm housing
Fuel: 93

Same car but with the 10cm housing installed.

Blouch 1.5XT-R-TS vs HTA68 vs FP Green

Blouch 1.5XT-R-TS

Blouch 2.5XT-R-TS (new housing) E85 2.5L

Moore Performance

This is a interesting one being that they have created their own header setup to use EVO turbo's. Limited info on these right now but great potential with many turbo options. They are currently working on a setup for TMIC.

UPDATE: New custom downpipe along with uppipe/header which work with the stock location turbo.

Base kit - $2950 (includes everything but the turbo)
With turbo- Starts at $3950

One benefit with this kit is you can sell your current setup entirely, which is really a pro for those with stock twin scroll. This could knock $1200-1400 off the price.

Pricing: Not listed for the twin scroll

Thread at Rexnet

Tomei Arms twin scroll


M7760: $1780 on their site (others say $2400)

Dyno graph by them, not impressive IMO

Thread comparing it to the single scroll version on a EJ205, did poorly but can be blamed a bit on the EJ205 not having avcs.

NEW results: triniscoob running it with supporting mods and meth (321whp/283tq) and mentions it is horribly laggy and poor overall.
