Welcome to IsuzuPiazza.com :: Uniting Isuzu/ Holden Piazza Enthusiasts since 2002

I have the following for those that are interested

across the page is engine, bore x stroke , cc , comp ratio

G200Zsohc 87x82, 1949, 8.8:1
G200Wdohc 87x82, 1949, 8.8:1
4zc1 88x82, 1994, 8.8:1
4zc1-T 88x82, 1994, 8.2:1
4zd1 89.5x90, 2255, 8.3:1
4ze1 92.6x95, 2559, 8.3:1

TheG200W DOHC did have higher power output than the G200Z SOHC but I have heard they were temperamental due to the secondary timing computer apparantly.

Different compression ratios may have applied when these engines were used in other applications such as vans and utes.

My info shows the G200W DOHC as having a 9.0:1 comp ratio

MAYBE THEY WERE ALLOWING FOR CARBON BUILD UP

I know, its frutrating, different results every where you look. I've got a bit of Japanese language stuff i thought I might bring with me when i head down your way , looks like 1st week of next month. Ill give you a text nearer the time.

The G200Z as found in the early Jackaroo here in OZ was 8.4:1.

Thats what my book states it covers. The later years and the motor in the Rodeo could be different. Not that it matters coz i dont think we have any G200Z powered Piazzas here.

Cheers. Bob.
