Hi im looking to do a swap and need to know which would be the best to make a lot of power???

how much power
how much money
boost or n/a
that is too broad of a question

Well i want to be making 500hp + when done and this is going to be a long term project, since im only 16. for the swap alone im looking to spend around $4000 max.

and i also plan on building the engine then boosting it later.

B18C... 180hp at the crank stock and they love boost. The swap will cost you right around $4k.
