Hayabusa Big-Bore Block Exchange

APE pioneered the big-bore Hayabusa block exchange program. WE have in stock, ready to ship; fresh 84mm Gen 1 blocks and premium Wossner pistons.

Pistons feature 13.5:1 Compression ratio, lateral gas ports, and coated skirts. Send us a “Good” Gen 1 block, not over 83mm and never surfaced, and we will send the 84mm block and pistons out the same day. Price is $897.00 Exchange. Head gaskets are also available with block purchase.

Hayabusa block exchange program
We also have several finished blocks and pistons available outright, no exchange.

*Note that CP and JE Pistons are available, but they are on long backorder.


APE offers a unique way to install oversize pistons in your Hayabusa without having to wait for weeks for the machining and replating process to be performed. We have big bore cylinders ready to install, available on an exchange basis. You send us your cylinder block in usable condition** and we send you a finished block and pistons ready to install. Our blocks are all precision bored and re-nikasil plated to the proper clearances.

**Blocks must be in nice shape, never surfaced, and have no damage. Slight bore scoring ok if it is a stock bore. Do not send us trashed blocks for exchange.
