Regarding engine, these are many options like 3s, 3sgte in petrol.
1c, 2c & 3c in diesel, not very fast but very good & durable engines.
You can also find a Mazda 1800cc petrol engine, it's rare but it can also be considered.
1jz & 2jz can also be added as a picture posted above from Islamabad but it needs a lot of cutting & chopping.
These are some suggestions based upon my limited knowledge.
Anyone can add to my suggestions or correct me for my lack of knowledge.
