FAQ Icon
Frequently Asked Questions
Do You Sell Custom & Performance Engines Direct to the Public?

Yes! We build the best performance engines available, anywhere. In fact, many performance engine merchants you find market and sell S&J performance engines under their label. We build every engine with our own highly trained & experienced S&J machinists, assemblers, and technicians at our facilities in Spokane, Washington, and we ship nationwide. Call us for a direct consultation for your specific application.

PAYMENT OPTIONS:

Purchasing your S&J Engine:

Easy! S&J Engines accepts all major credit and debit cards.

S&J 2Pay: Ordering your engine has never been easier! Pay half today, pay the balance later with no interest charge.

ENGINE PRICING:

We post our engine pricing up front, always. Custom builds are priced according to level of build; call us directly for options and pricing!

ENGINE CORE:

The engine core is what we use to remanufacture an engine. We price the core out separately so that it can be returned for reimbursement.

Core Availability:

Our vast inventories most often include the core for your engine. However, if our current inventory level require us to utilize your engine’s original core, we will contact you directly before proceeding to let you know what options are available.

Core Cost Reimbursement:

We refund you the cost of the core upon its arrival at our facilities. We reimburse you the cost of the engine core upon arrival at our facilities (less return freight cost). We handle all the logistics in getting your engine core shipped! It may not be cost effective to return the core if the freight amount is greater than the core refund due. In that case we recommend the core be sold locally.

SHIPPING COST:

Shipping costs are based on zip code. You can find your shipping cost with our Shipping Estimator, located below the engine image display.

If you lack a loading dock or platform, we offer the option of selecting a liftgate at the time of checkout.

SHIPPING TIMES:

Shipping times vary widely due to engine popularity, availability, and supply chain flow. Anticipate 6 to 8 weeks currently. You will receive notifications of shipping status.

WARRANTY REGISTRATION:

We allow 90 days from the date of engine shipment to enroll. If you need more time, contact us directly prior to the time allotment; we’re glad to help! Warranty registration is done online.

WARRANTY INQUIRIES:

We are here to get you your engine today and we are here to assist you if problems arise. If you experience issues with your engine within 90 days of installation, simply go online and submit a warranty inquiry. We’ll respond quickly to get your problem solved and you back on the road.

0% Interest Split Payments!

How it works

SJ 2-Pay is a layaway option. Use your own debit or credit card, or other accepted payment method to pay.


The first payment is charged when your order is submitted (unless extenuating circumstances exist, such as undetermined shipping costs, correct product [engine]). S&J Engines, Inc. will begin payment agreement after processing any corrected orders at no penalty to the shopper.


The next payment is made automatically 45 days after your first payment.


Your engine will ship when the balance is paid in full. If we complete your engine prior to 45 days, you have the option of early settlement at no penalty.


If your engine requires more than 45 days to ship your payment will be processed per layaway agreement. We will ship your engine as soon as it has completed the remanufacturing process and quality assurance testing.


S&J Engines, Inc. charges no interest with SJ 2-Pay and no fees unless you fail to make a payment or, in some circumstances, your payment is returned.


A Late Fee of up to 10% of the total purchase may be charged if any scheduled payment remains unpaid after 10 days (this will never exceed 25% of your Installment Payment amount).


If you cancel your order after three (3) business days from initial purchase we will automatically refund the amount you owe us, minus 7% of the first payment (deposit). If you already paid us for a refunded order, we will refund the balance back to your original payment method minus 7% of the first payment, subject to S&J Engines, Inc. Terms and Conditions.


Depending on your payment method, your financial institution may charge you interest or fees under your agreement with them. If you have any questions about those charges, contact your payment method provider.


Complete Terms and Conditions can be read here.
