Nissan used the Rb26 engine in some of its iconic vehicles. However, after discontinuing the production, they have recently brought it back. Now that, the pair of a new engine block and cylinder head will cost from $3,500 to $3,800.

Here, the cylinder head is the pricier option as it’s going to cost you at least $1,700. On the other hand, it’s fair enough spending $1,400 for a brand new engine block to bring an ultimate improvement in the vehicle’s performance.

RB26 engine cost

Rb26 engine is an iconic engine itself used in a number of iconic vehicles. However, it's an expensive addition to the vehicle as to the price of the overall cylinder head and engine block can go up to $4,300.

As you all know that without a powerful engine, the vehicle won't perform to its peak. And for this reason, it becomes necessary to turn on a brand new Rb26 engine head and block.

  • A brand new cylinder head costs from $1,700 to $2,300
  • A brand new engine block costs from $1,400 to $2,000.

Well, one important thing to know about the engine is that the components aren’t available in the USA. Therefore, it becomes mandatory to ship the required components from Japan.

That is to say, the cost of both the new engine head and block stays on the higher side as they include the shipping cost.

What is the cost of the Rb26 refurbished engine? 

It's not necessary to go for brand Rb26 engine components as you may run out of money soon when there's lots more to spend on the vehicle. Therefore, go for a refurbished cylinder head and engine block for $900 to $1,600.

The total cost seems going down half of what was offered for brand new components.

  • A refurbished cylinder head costs $500 to $850
  • A refurbished engine block costs $400 to $750.

Well, comparing the refurbished price to the brand new components price, the clearest picture suggests to us that the price has significantly gone down.

You are well capable of purchasing four refurbished cylinder heads with a similar amount of money used for buying a brand new one.

Again, the brand new price of the engine block is five times more than the cost of a refurbished engine block. That leaves no doubt about the cross-cutting measure of these two Rb26 engine components.

However, the crankshaft is one component that you can either take or continue with whatever you have built in the previous engine to save at least 800 bucks.

On the other hand, the cheapest component among all these is the bearings which won't cost you more than $200. Meanwhile, you also have the option to choose these bearings from either King or Clevite to have the intended performance.

Adding these components overall to the block and head creates two categories for engine rebuilding.

  • Rebuilding with refurbished engine
  • Rebuilding with a brand new engine.

The first one is the cost-efficient option you have for your vehicle’s engine, where the total expenditure ranges from $5,000 to $6,400.
