Not if you ever owned one. A motor swap makes it ungodly fast, but you have to wreck the car to do it. It isn’t unibody construction, it is monocoque. The engine bay is 19 inches wide at it’s narrowest and needs major surgery to fit a big motor. The extra weigh messes up the handling.
Mine has a Lenk suspension that is lowered 2 inches and handles well. There is also anouther cool thing about a small car. It is only about 4 feet wide, so I can put two tires on the white line in a turn, cut a nice apex, put two tires on the yellow line and end the turn with two on the white line again, all while staying in my lane.
I owned 5 70’s F bodies many with a stroker 383 built motor. The Opel gets more looks than all of them put together.
Monocoque is another word for unibody.
You should at least swap out for the Opel 2.4... And the turbo Pontiac 2.0L is almost a direct drop in.
The last time I saw an Opel GT, it was modified much like yours, lowered and with wider tires than stock, but it clearly had the stock 1.9L. Unfortunately for it, my much larger XKR could pull off the same tricks and it just got eaten in the straights. :D
Swap that motor out right away. :D
