Magnus VR38DETT GTR Crate Motor



No More Restrictions, No More Restrains

If you are looking into this path of adventure and excitement this means our mentalities collide. That’s right who likes to be confined by any restraints? The manufactures have no choice but to restrain the cars from their capabilities from factory. Although the GTR is already one mean machine, many believe it lacks in some aspects; the power being the main one.

The days where +1000whp cars were considered unsuitable for daily driving are over. We took our experience and knowledge, combined it with the GTR platform and made it possible for you to have an untouchable car both on the track & street while maintaining that stock driveability. Forget about building yourself a Sunday driver. Forget about having to tow your car on the trailer, forget about sitting on your porch and waiting to unleash your beast every weekend. With our crate motor you can go to work, take your kids to soccer practice, do your grocery shopping and even drive across country while making enough power to be untouchable at the track. Doesn’t sound bad for a bottom 8second quarter mile car does it?

Stage Who?

Here at Magnus we do not believe in stages. Unlike our competitors we are against cutting corners only to offer our customers with a cheaper engine. All of our engines receive the same high quality parts and machining whether making 300hp or 1,000+hp. Quality and reliability are our paramount concerns when putting engines together.  “Stage who?” is our stage and the stage that sets the standard in the racing world. We do not believe in these stages that the other guy created. We all know that these stages are a joke.

It all starts with a core

We do not cut corners on the core that we begin with. Every core we use is disassembled, cleaned and thoroughly inspected before being selected. Frost plugs are removed and replaced and squirters are disassembled, cleaned and inspected or replaced as needed. Surface is decked and the cylinders are honed with a deck-plate in a climate controlled environment. Block is clearanced as needed. Pistons, rods and crankshaft are installed, assembled and balanced

Let Us Do The Hard Work!

 The ease of install is exactly what we will provide you with! A simple drop, plug and play experience is all you will have. Fully assembled and sealed from valve covers down to the oil pan. Save yourself the headache, you will receive the engine already timed with the front covers on!
