SEH??

[ALLNOVA]

does anyone know if vauxhall ever made a 20SE? my 2ltr has 20SE on the block, but i aint sure if its an SEH? i know the SEH has flat-topped pistons but i aint checkin that way! :wink:

forgot to mention its not easy to read the code, its rusted to f**k :o

[m.d.]

mine is an se and it has offset dished pistons which are standard according to the pic in the haynes manual

[ALLNOVA]

so i could benefit from the SEH ECU?? couldnt see the pictures but if thats the case it must be the same spec as a 20NE. 115hp and 129lb.ft. have you modded yours m.d?? 8)

SE is high compression (s stands for 9.5-10:1) version
NE is lower compression version (n stands for 9-9.5:1)
SEH is a high output version of the SE which probably has upgraded cams, possibly a better head and a different ecu
