I stopped keeping track years ago so this is just a small fraction
my advice is to use a stock engine. Stock engine list of HP support for daily drivers:
sr20det up to around 320-350rwhp
2jz-gte and LSx are 500-600rwhp capable daily
If you are dead set on a rebuild then do a STOCK rebuild and follow FSM procedure, and do NOT allow a machine shop to touch the engine. If you need something "cleaned" or "shaved" buy another identical part that doesn't need that work done, never send it to the machine shop. That's where most mistakes occur. You will wait weeks/months for something and it will be done wrong, and you won't even know it until it costs the entire engine.
