Hi folks:
Starting this thread build should someone like to try this hybrid build.
1991 Corrado PG block 1.8L 8V G60, little history car sat for four years ran but has an engine knock, oil light on, makes no power. Reading through previous owners paperwork two items come to light one is the car is bored to 83mm and the second is it went through a lot of head gaskets. Was going to rebuild the PG engine until I came across a brand new AEB block with crank and intermittent shaft installed. Was cheaper buying this block than it would have been to do the PG block re-work.
Will be using stock 81mm pistons with new rings, stock conrods bolt up to the AEB crank conrod journals:
Here is a list of mods that need to be done to the block to work with the PG 8V head and G-Ladder:
Biggest mod is the rear support bracket of the G-Ladder requires a 5mm aluminum plate welded to it, machined to the shape of the crank vent port and a port tapped for a #10AN fitting which will be routed to the the G-Ladder return. This will supply additional lubrication to the supercharger.
Rear G-Ladder support bracket:
Modified to fit in the area:
Drill thru block and tap this existing bolt hole to accept the G-Ladder oil return
Install a frost plug:
Install crank position sensor (not used - only fills the hole):
An AEG head gasket is used with the stock 8V head, the three rear oil journals which aren't on the PG 8V head will be blocked when using this gasket:
Purchased BBM Stage 4 chipped ECU, 3.5 bar FPR, 268/260 cam, 65mm pulley
The intermittent shaft gear is the same pitch as the PG distributor:
The distributor and oil pump must match, PG distributor gear/oil pump have a slotted setup, while the AEB setup has a spline gear and oil pump, either one can be used:
