power figures 2.0

2.0 8V IS IT 115BHP OR 130BHP    ...  IF IT IS 115BHP COULD WE FIT THE ECU FROM A CAV SRI 130  ?  WOULD THIS GIVE US THE ELUSIVE 15BHP?

[geordie_boy1978]

say for example if you had a sri130 head lying around in the garage   and you were planning to rebuild your engine  would the sri head fit?

The 2.0 in the Carlton was (and this is a rough guide...)

20SE (122bhp) in the prefacelift

20NE (115bhp) in the facelift

The highest power from Vauxhall 8v (excluding any wierd ones) was

20SEH (130BHP) in the Cav SRis

The difference between SEH and NE is.... Cam, Pistons, Management

Apparently if you change the two easy ones (Cam, Management) you take the power to around 20SE levels.

Best off finding a complete 20SEH from a Cavalier Sri 8v and swapping it over. They go for buttons these days. hell I sold a sound one with FWD box for £30!

BTW, if you do want to swap the management I have been told that the Mk2 Cavalier SRis use a different loom plug to the ECU (and possibly different management... not sure) compared to the later Mk3 Cavaliers and the NE used in the Carlton.

Good reading

(its for an SER engine, which is virtually the same as the SEH IIRC)
