ENGINE BLOCK FAQ

How much do I have to pay to begin the process of engine breakdown and evaluation?

We require a $2,000 deposit to pull out the motor and evaluate the work needed.

Once our evaluation is completed, we require another $2,000 or 50% of the balance paid prior to order parts and machining. After parts are ordered and the required machining, completed, we require another $2,000 prior to building, and finally, the remaining balance to be paid upon engine re-installation, break-in map, and delivery. (Financing Options Available)

Do you have any recommendations on how to drive with my new engine? 

Yes, we recommend that you keep most of your driving moderate and under (4,500) RPM, for the first (750) miles or until your engine builder says otherwise. As well as continue to constantly fluctuate the RPM during this time and allow the vehicle to warm up fully before driving. If possible, drive the vehicle GENTLY until it reaches operating temperature and avoids wide-open acceleration in low gears to prevent engine damage. Full Break-In Procedure can be found HERE (link to New Break-In Procedure Form)
 

How should I drive with my new engine on the freeway?

We recommend that you briefly accelerate to full throttle when driving at the optimum highway speed.
 

How should I maintain the health of my new engine?

We recommend that you check for leaks during the first week, check coolant levels weekly, for the first 1,500 miles, and then monthly after passing that mileage. During break-in, new engines may consume oil, so we recommend that you check the engine oil frequently. Top off as required.
 

What oil do you recommend that I use when topping off my oil levels?

Yes, please make sure to use only AMSOIL Break-In Oil, during the first (750) miles or unless your service writer says otherwise.
 

With my new engine, how often should I change my oil?

(5,000) miles, with Motul 5w40. (Note: Oil changes are not included in engine build price.)
 

How often should I get my car tuned after engine build?

The build comes with a base map tune, but we recommend that an intermediate tune is performed at (1,500) miles and a full power tune, and A/C recharge is performed at (5,000) miles. (Note: A/C recharge, intermediate, and full power tune are not included in the engine build price.)
 

Do you guys warranty your engine builds?

Yes, we do. Please find our warranty information HERE (link to Warranty Info form)
