    I would imagine the turbo is suited to the engine it was designed for. Seeing as most diesels are low-rev torque machines I wouldn't expect the turbo to be any good on a low displacment high revving engine.

    I'm not familiar with that turbo but alot of the large turbo's used on compact cars were designed for diesel engines so the answer is yes depending of the orientation of the exhaust and compressor inlets and if it's too large or not a good match for your application.

    diesel motors are low rpm and the turbos are designed for that specific application. Gas turbos are designed for high rpm.

    It's not all about RPM boys, it's displacement and exhaust flow. A large deisel engine will flow more exhaust at a lower RPM than a small 4-cylinder engine running at a higher RPM.

    Alot of people post without knowing shit. DSM'ers have been using Holset diesel turbos for years. Turbochargers are fundementally the same whether they are on a gas engine or diesel engine, only the sizing varies. Diesel turbo's will usually be larger like the 50 trim variety and up (diesel engines run higher boost in alot of applications) so you have to ensure that it will fit your application as I said before.

    a lot of the turbo ford guys, and just recently the turbo dodge guys, are using holsets as well with great success. decent choice if you have a motor with decent displacement and don't want to spend a lot on a turbo.

    Apparently they can take alot of abuse and provide alot of bang for the buck.

    a guy in town used one on his GLH and was pulling consistent 111-112 mph on a 2.5L four, and i think you can snatch them off ebay for around $400

    the exhaust housing is usually the difference. compressor A/R's usually stay in the 60-70 range while the exhaust side is in the 1.18's.....

    Exactly, as long as the trims and flanges will work for your application, use it....
