The SEH is the non-catalyst high output version of the 2.0 OHC. It had higher compression (~10:1, can't remember exactly off hand), different cam profile, some mods to the head and a different ECU. It made 130hp. There was a slightly detuned version called the SER which was fitted to the Opel mk2 Kadett/Vauxhall mk2 Astra GTE which made 125hp.
I have both C20NE (catalyst version) and SER engines sitting in my shed. Unfortunately I can only use the C20NE in my car as its the only one I have paperwork for. Because of our emission laws, if you fit an older engine in a vehicle you have to prove its age so you can be exempt from the emission standards for the vehicle your fitting it in (emissions testing is based on the year of the engine rather than than the year of the car). Thankfully the C20NE engine I have was registered a few months before the cut-off date that requires catalysts by law (they were an option up to then - march '92 I think) so I can ditch the catalyst.

SBD? isnt a 1.7? on throttle bodies?
Yup, 1.6 bored out to 1.7 and throttle bodies.
I was at a car show this weekend and QED (another Vaux/Opel tuning company) had a trade stand there and were displaying a very nice cast aluminium block for the 2.0L OHC/DOHC engines Yum!
erfinder that sounds great if ya coudl do it that way
... also once ya figured it out i can get some part for my lanos also lol... only thing i should do also is kinda removing that darn limiter but then i need a new chip=lots of money :s (well over here anyways)

I think these German guys have chips for the engine as well but I have to wonder if they use a different ECU for the X16XE ( with different sensors)
I think there was a Polish company that did chips as well... not too sure.
I should pick up a Lanos ECU and pull the data off the stock chip (since I'm and electronics eng. tech. and I have a EEPROM reader/writer)
I haven't had a chance to fool around with ECU chips but I don't imagine it's all that bad.... the rev limiter is probably just a single line in the memory that needs to be altered.
To the best of my knowledge, throughout the years the european GM engines were mostly using Bosch based FI systems (Jetronic, for example), as opposed to the AC Delco systems in the North America.
With Daewoo, and some North America GM cars (Sunbird MPFI), it seems they are a hybrid of both...AC Delco using some Bosch ideas (like the air-flow meter flapper). From what I know, the Bosch systems are closed-loop, meaning the system is running off a map with pre-programmed values...on the other hand, the AC Delco systems (C20GET is the best example) uses open-system, in which the logarithm calculates most aspects of the engine operation, thus is able to adapt to new conditions, as it will try to meet pre-programmed output values.
Yum!
i dont mind doing that tbh if you get me a list if the parts you need
