Every Blouch turbo is a direct bolt-on replacement for the factory unit — same oil, coolant, and exhaust connections — with billet compressor wheels, ceramic ball bearing centre sections, and custom turbine housings that deliver dramatically more power while maintaining predictable spool and drivability.\u003c\/p\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eBlouch Turbo Range — XT-R \u0026amp; G2R Series Compared ▾\u003c\/strong\u003e\u003c\/summary\u003e\n\n\u003ch3\u003eWhich Blouch Turbo Suits Your Build?\u003c\/h3\u003e\n\n\u003cp\u003eChoosing the right Blouch turbo depends on your power goal, fuel type, and how you use the car. Here's how the range breaks down:\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e5356 G2R\u003c\/strong\u003e — 53mm turbine, G2 compressor, ~420bhp capacity. Quick spool, strong mid-range. A great step up from the factory VF turbo without sacrificing daily drivability. The entry point into the Blouch range.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003e5860 G2R\u003c\/strong\u003e — 58mm turbine, G2 compressor, ~480bhp capacity. Bridges the gap between the 5356 and Dominator 1.5. Fast spool with a broad powerband. Strong option for street\/track builds on pump fuel.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDOM 1.5 XT-R\u003c\/strong\u003e — 56.5mm turbine, 49 lb\/min XT-R compressor, ~480bhp capacity. The fastest-spooling Dominator. Uses a smaller turbine wheel than the 2.5 for dramatically improved mid-range response while trading a small amount of top-end. The go-to turbo for street\/track WRX and STI builds that prioritise response over peak power. Available in 8cm and 10cm housings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDOM 2.5 XT-R\u003c\/strong\u003e — 60mm turbine, 49 lb\/min XT-R compressor, ~490bhp capacity. The original \"Polka Pickle\". Slightly more top-end than the 1.5 with a marginally slower spool. The sweet spot for builds targeting 350–400whp on pump fuel or 400–450whp on E85.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDOM 1.5 G2R\u003c\/strong\u003e — 56.5mm turbine, 52 lb\/min G2 compressor, ~520bhp capacity. Latest-generation compressor wheel with improved aerodynamics pushes more air than the XT-R at the same turbine size. Faster spool than the 2.5 with a higher power ceiling than the 1.5 XT-R. Available in 7cm and 10cm housings.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDOM 2.5 G2R\u003c\/strong\u003e — 60mm turbine, 52 lb\/min G2 compressor, ~540bhp capacity. The G2 compressor wheel on the full 60mm turbine. Strong mid-range with a higher ceiling than the 2.5 XT-R. Ideal for builds pushing past 400whp.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDOM 3.0 G2R\u003c\/strong\u003e — 62mm turbine, 56 lb\/min G2 compressor, ~600+bhp capacity. The biggest bolt-on Dominator. Built for high-horsepower EJ builds on E85 or race fuel with full supporting modifications. Slightly slower spool but massive top-end capability.\u003c\/p\u003e\n\n\u003ch3\u003eXT-R vs G2R — What's the Difference?\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eXT-R series\u003c\/strong\u003e uses Blouch's proven billet compressor wheel with 49 lb\/min airflow. The \u003cstrong\u003eG2R series\u003c\/strong\u003e uses the latest-generation G2 compressor wheel with improved aerodynamics and 52–56 lb\/min airflow. The G2R spools similarly to the XT-R but flows more air at the top end, giving you a higher power ceiling from the same turbine size. The G2R is the better choice for new builds; the XT-R remains an excellent turbo at a lower price point.\u003c\/p\u003e\n\n\u003ch3\u003e8cm vs 10cm Turbine Housing\u003c\/h3\u003e\n\u003cp\u003eSeveral Blouch turbos are available in both 8cm² and 10cm² turbine housing options. The \u003cstrong\u003e8cm housing\u003c\/strong\u003e builds boost faster and spools earlier — ideal for street cars, smaller displacement engines, and lower boost targets. The \u003cstrong\u003e10cm housing\u003c\/strong\u003e flows more exhaust gas at high RPM, reduces backpressure and exhaust gas temperature, and supports higher power levels — better for track cars, high-boost applications, and E85 builds. If you're running 20+ PSI or targeting 350whp+, the 10cm housing is usually the right call.\u003c\/p\u003e\n\n\u003ch3\u003eSupporting Mods You'll Need\u003c\/h3\u003e\n\u003cp\u003eA turbo upgrade on its own won't make power — you need supporting modifications to feed it and get the exhaust out.
