In this article we use a 1992 B17 VTEC head. However, you can use any VTEC head (B18C1, B18C5, B16, B17). You will also need about 3 feet of braided stainless steel line which can be ordered from www.racerpartswholesale.com.
You will also need the following:
. LS headgasket
. B18C water pump
. B18C timing belt
. B18C head bolts
You may choose to use a non-VTEC water pump, however you must then use a B18A non-VTEC timing belt. You can also use to use a VTEC oil pump since it has higher flow as compared to the non-VTEC units.

We chose to use P73 ITR pistons |
 |
We chose LS rods to use with the ITR pistons. With a stock deck height and stock headgasket it should put compression at around 10.9cr. |

1991 LS B18a block. This block used because it is in very good condition and has an oil/water seperator in the back of the block just like the B17a. |
 |
Since the motor will seeing 7500-8000rpms its a good idea to upgrade the stock rod bolts to ARP units. If you are using stock LS rods, you will need 1.2-1.6 rod bolts x 8mm. Part # 208-6001. DO NOT use the VTEC 1.8 x 9mm units. |

-4an braided stainless steel line fittings. You will need four of these. Part # FCM-1011 www.racerpartswholesale.com |
 |
-4AN to 3/8NPT plug needed to plug the intake side of the head for the oil supply. This is an Aeroquip part # FCM-2519 |
 |
1/8NPT plug to seal the oil hole on the head. This is an Aeroquip part # FCM-3685 |
 |
This is the oil feed setup. There are several ways one can do this. This method is to run the SS lines to a Tee on the firewall rather than Tee'ing from the back of the block. |
