Will I regret not buying a complete jdm engine.
Thanks in advance. I have been reading threads and stickys for a few weeks. One thing I have noticed is some threads are 15 years old, and new products and ideas have emerged. I am planning to do a t2 swap into my 81 fb. I have 100 questions, but I will stay general. Is it crazy to buy an engine from rx7 world or rotary engines, and piece together everything else? Or, is it much smarter to buy a jdm setup to get the manifolds, sensors, etc? Would you rebuild the jdm motor or buy a rebuilt engine and swap the parts over? I know its a lot, and if theres threads specific to the options currently out there please direct me. Again, thanks.

buying a used (JDM) longblock is always a gamble. With the age of the engines and how long they've been sitting, your chances that something is seized are pretty high. That being said, JDM engines are a great way to get a full swap for a decent price. Piecing thing together will be pricey and/or time consuming.
JDM Swap
Pros:
1. "Full swap" (minus drive shaft & fueling)
2. possible aftermarket parts already on engine (i've seen some nice turbos, twin discs etc. essentially free)
3. easy to source
Cons:
1. High possibility of lock-up due to storage conditions & time
2. Some places dont let you check the engine compression to verify
3. Might require rebuild in the future anyway
Piece together swap w/ rebuilt engine:
Pros:
1. you get to choose which parts to mix/match
2. everything you buy will be "new"; good piece of mind there.
3. You can choose a reputable builder
4. You can mod as you like
Cons:
1. More costly depending on how you choose to go
2. It will be time consuming to source various parts if you're not buying new or trying to save $$
A lot of guys have had good success buying JDM engines. I've struck out the two times I purchased and was refunded the 1st time but not the second. There's no real answer to your question without knowing what you budget is and what you want the car to do.
Cheers,
Nec

Thanks for the reply! I am not in a huge rush to get this done. I have time to plan and piece it out. Ultimately, I would like to keep the budget under 10k. I am a believer in buy once, cry once. My bigger concerns are around sensors and wiring harness. I plan on using the micotech lt9c standalone. I also wanted to do an upgraded ball bearing turbo. My plan is to aim for 325-350whp and 8500 redline, nothing extreme.
