early rolla is right on the numbers, except for capacity the pumps are identical just larger vane/gears in the GT pump so they used a shit metal insert about 20mm. As for comments by the TAFE teacher about the pumps being average. I have an 18RG engined RT104GT original factory circa 1974. Oil pressure was always about 70 psi. I used to ring the crap out of this engine to 7000 rpm all the time up and down the Grampians, and at the Ararat and Camperdown Hill climbs. It was also used as the Service car in the 1976 Singpore Airlines Rally carrying half a Corolla spares contingency in the section from Perth to Sydney and again in the 1978 Repco. I broke a ring and did a top overhaul at 100,000 km. The engine was topped at 100,000 km and had rings fitted, it now has 242,000 km and the oil pressure is still 65 psi. The GT oil pump is original I still have a new spare ina box circa 1976 along with carbies and other gears/chains that I never used/needed. I think we changed the dummy oil shaft as the cast gear driving the dizzie looked a bit thin. The Toyota companies who did all this work are long gone but the car still starts and runs and is in storeage. We reshafted the carbies last year at Shaun Maloney's workshop in Carlton at 240,000 km. The Modified OIL PUMP in the HIGH Ace is simply this.... The pick up pipe which bolts below the vane/pump assembly is direct and straight in the RA series Celica and has an elbow neck in the R series Corona because the latter had a subframe cross member, whereas the Celicas and T18's had struts and no cross member. So if you look at a Corona SUMP where there is a cross member the sump is shallow at the front and deep at the back so they goose necked the oil pick up pipe to go deep into the oil pan. In the Celica however (with the 18R) and T18 3TC, the Sump is just a trough so the oil pump pickup just can go straight down from the distributer deep into the oil. To convert one way or the other get hold of the down pipe input piece and gauze filter. So go to wreckers and ask them to show you a Celica Oil Pump and a Corona Oil pump, ALL WILL BE REVEALED. There are no mysteries in four stroke engines just experiences. [Updated on: Tue, 07 September 2004 05:46] [Report message to a moderator]
