Did reply to this lastnight, but it appears that the post didn't appear, ok here goes again.
I think the engine was standard, but obviously the car would have been a lot lighter, because interior would have been stripped and mechanical parts would be lightened, also breathing to the engine would be a lot lot better.
I'm not exactly sure, but if the car is Group N I don't think to many mods can be made to the engine anyway.
If you want stuff doing to yours, check with Avanti Motorsport they may be able to do stuff.
Hope this helps
