I think if you chose either cam you would significantly increase the number of dollars you've spent on the motor which is where the upgrade will be most noticeable. at least with a thinner wallet, your butt dyno will be lower in the seat and you might be able to feel a difference.
in all seriousness, you should take all future funds you plan on spending and save for a dual overhead cam 2rz/3rz and never look back. i feel like I am pleading with a gambling addict who thinks if he keeps spending more he will win
As I move through this rebuild project, I am concerned about my out of pocket costs in money. I grossly under estimated the cost and time of the project.
I am not happy with the outcome and disappointed that the number of real and potential failures is so unexpected… it’s my inexperience and insufficient pre-start research.
I hope to get it running right without too much more financial investment. Although I’m well north of $5,000, so a few hundred here and there to get it running the way I think it should doesn’t seem so significant now.
Regarding engine swaps, at this point, I would only consider swapping in a Toyota 22R, no other Toyota engine. As I said, I will keep an open mind.
If I do an engine swap it would be Chevy 4.3L Vortec or I might build a 215ci aluminum block, like the old 1963 Buicks… but to get a referee pass and passed any emissions testing could be problem.
By the way, I’m not a gambler, but I am somewhat eccentric and probably addicted to my quest to make this rebuild successful.
