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.
"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
LM400-s60 billet vs VF42 (2.0l JDM AVCS (intake), supporting mods: Kelford 264/260, ID725, 3-port solenoid, adjustable cam gear (exhaust). 3'' exhaust)
Thread on Scoobynet
Right now nothings listed on Blouch site, but they make the turbo's for scoobyclinic. They all use billet wheels.
This is how Scoobyclinic lists them:
SC42 (20g custom turbine)
SC46 (49lb/min) - $1,600 + sending in a VF36/37
This is how Blouch lists them: (They don't list the 16G SC36)
18GXT-TS: 44lb Journal Bearing
20GXT-TS: 47lb Journal Bearing
1.0XT-TS: 49lb Journal Bearing
1.5XT-R-TS: 47lb Ball Bearing 56.5mm Turbine (2.4" inlet standard or 3" for extra $100)
2.5XT-R-TS: 49lb Ball Bearing 56.5mm Turbine (2.4" inlet standard or 3" as option) (this is the SC46)
I don't have pricing from Blouch for anything other than the SC46. The other prices are on scoobyclinic but much higher than they would be if we went through Blouch (shipping to the UK etc)
These turbos don't come with a P&P or thermal coating.
P&P = $150
Thermal coating = $180
SC46 twin scroll E85
SC46 twin scroll on meth
SC36 (Single scroll I think)
SC36 20% meth
SC40 (single scroll prolly)
SC46 (single scroll prolly)
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.
Blouch results on Nasioc:
Blouch 1.5XTR-TS (it says 2.5, but blouch now call it the 1.5. This uses the 8cm I believe)
Blouch 1.5XTR-TS on a 2.5 with 8cm housing
Same car but with the 10cm housing installed.
Blouch 1.5XTR-TS(10cm) vs HTA68 vs FP Green
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.
Custom Borg Warner
Evo8 used turbo
GTPS05T (TD06SL2-73HTA) twin scroll
GTPS03T twin scroll (TD06SL2-20G)
GTPS02T twin scroll (TD05H-20G)
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.
Prices/Name of turbo not known yet.
