This thread is to address any questions on how to properly build a gsr shortblock. The components used were Manley/Full race connecting rods, CP 81.5mm 9.8:1 pistons, OEM bearings and other OEM components.
Before I begin this article the shortblock was overbored from 81mm to 81.5mm. Overboring the cylinder walls 0.5mm is proper engine building technique. This is done to ensure that the cylinder wall is a true circle from the top of the bore to the bottom.
The list of tools that you’ll need to do a proper bottom end assembly are the following:
- Dial bore gauge
- Rod stretch gauge tool
- Micrometer
- 3-4" machinist measurement tool
- 2-3" machinist measurement tool
- Plastic gauge
- Torque wrench
- Feeler gauges
- Ring filer
- Tap set
- Ring compressor
Other supplies that you’ll need are:
- Brake Kleen
- Credit card/plastic straight edge
- Arp bolt assembly lube
- Clevite bearing lubricant
- SAE 30 wt oil
The beginning of this article is going to start with the engine taken completely apart. You’ll have to dis-assemble the entire block to get to the point where pictures start.
The first step is to clean down all the bearing surfaces, lets start with the mains/block girdle. Use fresh, clean paper towels and Brake Kleen to wipe down all the surfaces:
