Help needed please. I recently purchased my mates 77 ke30 as I seen it as a bargain, however now the problems have begun. So at the moment the car has a 7k 1.8ltr motor out of a Toyota townace, so I have been told. It has a 5speed in it not sure at this point what 5 speed though, possibly the one out of the townace itself? Brakes are original. Motor has had abit of work done to it, twin webber carbs, I'm thinking possible head work, extractors and which looks like 2inch or 2.25inch exhaust system. So basically my problem is my mate bought it with rego and has since let It run out of rego and it now needs a blueslip, problem is I'm unsure if it needs an engineers cert or not as I do not have one. I am aware that the general rule of thumb is no to exceed 20% greater than the original motor, however I called an engineer today and he said that the 20% applies to whatever the biggest engine was that was released in that chassis. I'm under the impression that a couple of later k series models used that same chassis up until 1981 an that one of them had a 1.6ltr motor so basically just wondering if that is the case and will I be able to get it blueslipped or is it definitely in need of an engineers cert. Also the Toyota compliance plate says 3k-c, the rego papers say 4k and the engine block clearly says 7k lol wtf.. Any advice or help anyone could offer would be awesome as the car is great fun to drive and I just want to get it on the road again.
