Dear Porsche Enthusiast, 

Thank you for your inquiry. We very much appreciate the opportunity to provide you with the components you need for your PORSCHE. We are including a partial list of our products and prices, as well as other data you might find interesting. We offer numerous other items not listed here, as that list would be too long, but hope the following will help you in selecting what you want to do to your PORSCHE.

For 12 years PowerHaus has been the #1 source for:
 

 
Regarding prices, we have a simple policy: our parts come to you as kits ready to install - our competitors do not provide these necessary items because these items cost money, and it takes a lot of effort to prepare them for you to make your installation easier and less expensive in the end! This makes our parts and prices a better deal for you than anyone else’s. We also have many used parts available that can save you even more per item - call and check us out. 

We have a complete line of turbochargers, from the original stock K26 to upgrade high-performance turbos. All turbochargers are quick-spool street & racing turbos - K27s, custom PH K27/29 hybrids, and more. We also offer special non-water jacket turbos for special applications. 

Some special items include our custom high-efficiency aluminum oil coolers and billet aluminum performance clutches -- items engineered by PowerHaus and not available elsewhere.

Another example of our product line is our 2.8 Liter upgrade package for your 944 Turbo. The custom Mahle pistons work in conjunction with our stroker crank and lightweight billet rods to make your 4 cylinder a ROCKET.

NEW: PowerHaus 3.0L Turbo conversions with either the 8V or 16V - heads! 400hp at the wheels!
No iron or steel cylinder sleeves, no welded crankshafts - 100% Reliable Power!

Every product we sell has been extensively tested in both street and track conditions. All performance modifications are backed by numerous chassis dyno runs using the latest, most accurate equipment available -- real numbers & no BS.

Call us for all your needs, even custom built items. We have most parts in stock, and can always do a better job for you.

1. PowerHaus K-27 Turbocharger Conversion: All 1986-1988 944 Turbos came equipped with a K-26#6 turbo, and the 1988 ½ - “89” models came with a K-26#8. The main difference is size of the exhaust housing and turbine wheel. The larger # 8 turbine and hotter computer chips were the only major differences between the engines, and while the S model had a little more high rpm horsepower, the turbo also built boost later (more turbo lag).
    For most street applications the #6 housing is recommended, as this gives greater throttle response. Coupled with the K-27 compressor, you have a dyno’ed gain of 35hp.
    To ease installation our turbo is sold as a complete kit, including a new temperature sensor (the old one no longer fits), as well as a turbo inlet adapter for the larger K-27, and other custom pieces only available from PowerHaus.

 
1a. PH K-27-DR Turbo Conversion: A special quick-spool version of our K-27 that combines the top-end power of the #8 turbine with the low rpm responsiveness of the smaller #6 turbine. Ideal for drivers seeking the most performance from their 944 Turbo. A PowerHaus Exclusive!

 
1b. PH K800R Turbo Conversion: A very high-flow (800cfm) turbocharger for highly modified 2.5L racing engines, or 2.8L and 3.0L Turbo engines. Roughly 20hp more than the K-27. Very easy installation requiring minor modifications (near bolt-in). A PowerHaus Exclusive!

2. 3.o bar Fuel Pressure Regulator: for K-27s

3. PH Engine Management Chips: Our chips are designed to work specifically with our turbo and exhaust packages, and can be custom-tailored for your specific vehicle. Required for K-27 turbos. 
Trade-in credit for certain used chips-please call.

 
4. PH Stainless Sport Exhaust System: Our lightweight bolt-in exhaust system replaces the restrictive factory exhaust. 
· The catalytic Test Pipe eliminates the two separate pipes for the engine exhaust and the wastegate, instead plumbing them into one mandrel-bent stainless steel test pipe eliminating the catalytic converter. 
· Our Sport Muffler also uses mandrel-bent stainless steel tubing and a very lightweight stainless canister - a bolt-in, free flowing package. Combined, our exhaust weighs less than half as much as the factory system - only 26lbs!

 
5. PH Mass Flow Sensor: The next upgrade is the PH Mass Flow Sensor for the 944 Turbo. This includes a pair of custom computer chips for the Mass Flow, as well as a K&N cone filter.
PH can customize the chips and sensor for the K-27 turbo, as well as any other engine modifications. The Mass Flow (hot wire) sensor makes the throttle response much faster, offering big drivability gains throughout the rev range. Overall horsepower and torque is greatly improved, especially when used with our K-27 turbo. We recommend buying the Mass Flow at the same time as the K-27 turbocharger to prevent buying chips twice, and as we will modify the kit at no extra charge to fit directly to the PH K-27 turbo with no headaches

(Manifolds are in stock to save you the 4-6 week wait of sending yours to Extrude Hone.)

 
7. PH Clutch Packages: Complete heavy-duty clutch & flywheel packages engineered to handle increased power and torque, while letting your engine rev up quicker: 
Street: PH lightweight billet aluminum pressure plate @ 3400lbs clamping force, 5lb weight savings. Uses Sachs Sport organic disc, included. Ideal pedal effort for street & track.
Sport: As above, but includes replacement lightweight flywheel (exchange) - Additional 6 lb. savings for better throttle response.
* All packages include a new OEM release bearing, guide tube, all hardware, pilot bearing, and main seal. *

 
8. PH Aluminum Oil Cooler: The largest, full-width oil cooler possible for the 944 Turbo (more than twice as large as our “competitor’s” cooler!) Our custom oil cooler solves most overheating problems by adding 2 Liters more oil to the system. The kit is complete with braided steel lines & adapters, and the cooler has a drain plug built into it to ease oil changes. On average, we see a 20C/36F coolant temperature drop! Easy installation, a must on 2.8L conversions.

 
9. PH Oil Pan & Pickup Tube: A must on racing 944 Turbos, our modified oil pan virtually eliminates #2 con rod bearing failure! Includes modified oil pickup tube.

 
10. PH 2.8L Engine Package: PowerHaus is the industry leader in 944 Turbo developments. We have built scores of 2.8L engines with incredible results: the jump in torque and horsepower is overwhelming. With this setup it is possible achieve 500hp and 500lb/ft without engine management. Boost response is instantaneous; there is no turbo lag! Kit includes 4 custom Mahle pistons, 4 custom forged rods, special bearings, and a new long-stroke crankshaft race-prepared to PowerHaus’ own specs. Further custom lightening and race machining also available.

* PH Billet High Performance Wastegate: Tested on our 500+ horsepower 2.8L and 3.0L 944 Turbos. Cannot constantly bleed off pressure like the OEM wastegate does, so the boost to builds faster and peak performance improves, too. Dual-port design works with all external boost controllers. Nickel alloy base, stainless & aluminum upper housing, CNC machined -- superior to the OEM unit in every way. 
Compact design bolts in place of factory unit with minor modification - custom 951 installation parts by PowerHaus included.

* Digital Air:Fuel Ratio Monitor: 52mm with 10 LED’s to display lean or rich air/fuel mixtures. Helps you adjust to the optimal fuel pressure.

 
* Billet Aluminum Instrument Panel: Mounts under the stock radio with CNC-machined cutouts for the electronic boost controller (with mounting brackets), intercooler monitor, and a 52mm gauge. Available with any CNC cutouts: 3x 52mm gauges, no intercooler monitor, etc… Anodized black; powdercoat or polished finish also available.

 
* Racing non-water jacket Turbo Kits: 944 Turbo racecars can benefit from eliminating the turbo’s center bearing water jacket. Reducing your engine’s water temperature to help prolong engine life, reduce detonation, for more horsepower and torque.
