1800 Head For 1592 Engine and 84mm Pistons?

Post by 73CS1592 »

Hi,

Quick question, is it possible to put a 1800 head on a 1592 engine? 132 engine with capacity 1592 and 132 engine 1756 are the same engine block with different bore if I'm correct.

COMPRESSION RATIO DATA

Jon Logan (Midwest124.com) had an excellent write up on this in the Summer 04 edition of Ricambi, the bi-monthly publication of FLU. In the article he calculated and compared the Static compresson ratio of all combinations of stock 2L pistons, stock 1.8 pistons, Kobenschmidt pistons (1.6mm domes), Mondial pistons with 4.5mm dome, Mondial pistons with 8mm domes, 2L and 1.8L heads, and 2L and 1.8L blocks. You may be able to get reprints from him or FLU, or I could make a copy of the article to send to you.

Here is a list of his calculated compression ratio results:

2 Liter Block and Head and Stock 2L Pistons---- 8.1
2 Liter Block and Head and Stock 1.8L Pistons---- 8.17
2 Liter Block and Head and 1.6mm Dome Pistons---- 8.85
2 Liter Block and Head and 4.5mm Dome Pistons---- 9.93
2 Liter Block and Head and 8mm Dome Pistons---- 10.75
2 Liter Block, 1.8L Head and Stock 2L Pistons---- 8.53
2 Liter Block, 1.8L Head and 1.8L Pistons---- 8.61
2 Liter Block, 1.8L Head, 1.6mm Dome Pistons---- 9.37
2 Liter Block, 1.8L Head, 4.5mm Dome Pistons---- 10.62
2 Liter Block, 1.8L Head, 8mm Dome Pistons---- 11.57
1.8 Liter Block and Head, Stock 1.8L Pistons---- 8
1.8 Liter Block and Head, Stock 2L Pistons---- 7.93
1.8 Liter Block and Head, 1.6mm Dome Pistons---- 8.75
1.8 Liter Block and Head, 4.5mm Dome Pistons---- 9.96
1.8 Liter Block and Head, 8mm Dome Pistons---- 10.91
1.8 Liter Block, 2L Head, Stock 1.8L Pistons---- 7.58
1.8 Liter Block, 2L Head, Stock 2L Pistons---- 7.51
1.8 Liter Block, 2L Head, 1.6mm Dome Pistons---- 8.24
1.8 Liter Block, 2L Head, 4.5mm Dome Pistons---- 9.29
1.8 Liter Block, 2L Head, 8mm Dome Pistons---- 10.1

Of course, if you have modified combustion chambers, shaved heads, decked engine block, different thickness head gasket, etc. then the numbers will be somewhat different. His article includes the dimensions for his components.

Thanks but it doesn't mention anything about the 1592 engine.
