An 800-hp target sits right at the boundary between a single big-frame street/strip turbo and serious drag-race hardware, so sizing matters more here than at almost any other power level — go too small and you choke off the top end, go too big and low-end response disappears. Everything below is a genuinely current, currently-sold gasoline performance turbo rated to cover 800 hp (several with real headroom above it), priced off real listings rather than guessed. This list skips a few tempting budget options: cheap universal turbos advertised as “600+ hp” tops out well short of 800 and would be a wrong fitment answer dressed up as a cheap one.

The picks, in detail
BorgWarner EFR 8374
BorgWarner’s EFR (Engineered for Racing) big-frame turbo, a single-turbo mainstay in the 500-800 hp range and good to roughly 1,300 hp in a twin-turbo pair.
- 74mm Gamma-Ti titanium-aluminide turbine wheel
- 83mm compressor with 62.6mm inducer, 79 lb/min max flow
- Ceramic ball-bearing center section, optional water cooling
- Sits right at the top of its comfortable single-turbo range at 800 hp, so it isn’t oversized for a street-driven car
- Integrated internal wastegate options simplify plumbing versus an external-gate big single
- Right at its flow ceiling for 800 hp — a build that might grow past that should look at a larger frame instead
- Titanium turbine wheel commands a premium over a stock-material equivalent
Precision Turbo PT6266 Gen2 CEA
Precision’s Gen2 CEA-compressor 62/66, a widely used ball-bearing big single with an 800-hp rating and Precision’s deep aftermarket support network.
- 62mm CEA billet compressor wheel, 2618-forged aluminum
- Gen2 66mm/76-trim CEA turbine wheel
- Dual ceramic ball-bearing CHRA, air-cooled
- Purpose-rated for exactly this power band rather than an oversized unit pressed into service
- Custom-built per order (cover, housing, A/R, outlet), so it can be tailored to the rest of the build
- 3-5 week build lead time since it’s assembled to order, not off-the-shelf
- Air-cooled only bearing design — no water-cooled option on this model
Precision Turbo PT6870 Gen2 CEA
The step up from the PT6266, rated to roughly 1,100 hp — a deliberate headroom pick for anyone who expects 800 hp today to become more later.
- 68mm CEA billet compressor wheel
- Gen2 70mm turbine wheel
- Dual ceramic ball-bearing CHRA
- Meaningful headroom above 800 hp means no turbo swap if the build grows
- Shares Precision’s Gen2 CEA compressor family with the PT6266, so tuning notes and support carry over
- Larger frame spools noticeably later than the PT6266 at the same 800-hp target
- Costs more than a turbo actually sized for 800 hp alone
Garrett G30-900
Garrett’s compact G-Series frame rated up to 900 hp, aimed at 2.0L-3.5L engines that want a quicker-spooling turbo than the larger G35.
- Ball-bearing center section
- Advanced G-Series aerodynamics for a wider efficiency island
- Standard or reverse rotation options
- Smaller frame than the G35-900 spools quicker for the same rated ceiling, a genuine advantage on a smaller-displacement engine
- Garrett’s widest dealer/support network of any brand on this list
- Best suited to smaller-displacement engines — a large-displacement V8 will outgrow its efficient range faster than the G35
- Sold as a bare turbo; housing and A/R chosen separately add to the total cost
Garrett G35-900
Garrett’s larger G-Series 900-hp frame, a common pick for V8 street/strip builds targeting 800-900 hp on a bigger-displacement engine.
- Ball-bearing center section
- G-Series compressor aero for a broad efficiency range
- Multiple turbine housing A/R options
- More top-end flow headroom than the G30 for a large-displacement engine at the same power target
- Same G-Series bearing and support ecosystem as the G30-900
- Larger compressor spools later than the G30-900 on a smaller engine
- Pricier than the G30-900 for builds that don’t actually need the extra frame size
Garrett GTX3584RS Gen2
The largest of Garrett’s GTX35 dual-ball-bearing line, rated 550-1000 hp, with a Gen2 10-blade compressor Garrett rates up to 20% higher flow than the original GTX3582R.
- 10-blade GTX Gen2 billet compressor, ~90 lb/min flow
- Dual ball-bearing CHRA
- V-band or T4 turbine housing options
- Widest published power band of any turbo here (550-1000 hp), giving margin on both ends of an 800-hp target
- Gen2 compressor update measurably outflows the prior-generation GTX3582R it replaced
- Priced at the higher end of this list depending on turbine housing choice
- Broad power band means it isn’t optimized as tightly for exactly 800 hp as a purpose-sized 62-66mm unit
Turbosmart TS-2 6262 (water-cooled)
Turbosmart’s water-and-oil-cooled 62/62 ball-bearing turbo, rated 650-800 hp with a lightweight investment-cast turbine housing.
- Water and oil-cooled ball-bearing CHRA
- Investment-cast turbine housing
- V-Band or T3/T4 inlet options, multiple A/R choices
- Water cooling extends bearing life under sustained street/strip duty compared to oil-only designs
- Sits right at the top of its rated band at 800 hp, so it’s appropriately sized rather than oversized
- At the very top of its 650-800 hp rating, leaving no real headroom for future power gains
- Multiple A/R and inlet configurations mean price varies more than most turbos on this list
Turbosmart TS-1 6262 (oil-cooled)
Turbosmart’s oil-cooled entry-tier 62/62, rated 760-880 hp — the tightest match on this list to an 800-hp target specifically.
- Oil-cooled ball-bearing CHRA
- Cast stainless turbine housing
- Ultra-low rotating mass compressor aero, T14 Inconel turbine wheel option
- 760-880 hp rated band centers almost exactly on 800 hp — less over- or under-sizing than most turbos here
- Lower cost than the water-cooled TS-2 for builds that don’t need the added cooling
- Oil-only cooling runs hotter under sustained high-boost duty than the TS-2’s water-cooled design
- Narrower rated band than the TS-2 or Garrett GTX3584RS, less forgiving of a build that grows
BorgWarner S366 SX-E
BorgWarner’s updated 66mm SX-E frame with a billet compressor wheel, rated to roughly 900 hp and popular in both street and diesel-compound builds.
- 66mm forged-milled billet compressor wheel
- 94 lb/min max airflow
- 360-degree severe-duty thrust bearing, ported-shroud compressor cover
- Billet compressor wheel and updated thrust bearing over the older S366 give real headroom above 800 hp
- Widely used across both gas performance and diesel compound-turbo builds, so support and tuning data are easy to find
- Sold as a supercore in many listings — confirm you’re pricing a complete turbo with turbine housing, not just the core
- Needs a properly matched turbine housing A/R chosen separately for the target power level
Buying tips
- Match the turbo to your actual engine displacement, not just the horsepower number — the same 800-hp-rated turbo spools and drives very differently on a 2.0L four-cylinder than on a 6.0L V8.
- A turbo rated right at the top of its band (like the Turbosmart TS-2 6262 at 650-800 hp) leaves no room for a later tune bump; one rated with real headroom (BorgWarner S366 SX-E, Garrett GTX3584RS Gen2, Precision PT6870) costs a bit more up front but avoids a second turbo purchase if the build grows.
- None of these prices include the turbine housing A/R, wastegate, oil/water lines, or tuning — budget for the full install, not just the turbo itself, before comparing sticker prices across brands.
