Is there a way to build the 3.6L to handle FAI before you add the FAI, or would you being throwing good money after bad?....I would not use a 3.6 other than stock. If you are definitely seeking performance, then use a performance built engine.
The pistons and rings are key components that aren't up to the task in my opinion. The increase in compression and combustion pressure and temperature can push the pistons and rings to failure. Not to mention the head gaskets.Is there a way to build the 3.6L to handle FAI before you add the FAI, or would you being throwing good money after bad?
I wont't give up my manual, but I want more power out of my little 3.6, especially in the 2-3k range. I was going to go Eldebrock, but if I need to swap pistons, rings and heads before I install, then it might not be worth it.
Could not agree more! Everyone thinks these conversions are easy and cheap to do. Never turns out that way if you want it right. I only had 45,000 miles on my TJ and went with a bolt on supercharger that ended up costing about 4k all in. Everyone was telling me I could swap a V8 for the same money... Never had a problem with the supercharger or added expense behind initial cost for supercharger, pulleys, and gauges.My JL diesel engine is stock but I do also have a LS 5.3(LH8) / 4L60E conversion on my 06 LJ Rubicon. I had 186k miles on my original 4.0 and talked myself into an engine conversion. I would not do it again. I had the work done at a professional shop that specializes in Jeep conversions and has had several Jeeps at SEMA. Even with all their experience, things like tuning & cooling produce a whole host of gremlins. Count on several trips back to the shop to tighten up loose ends. Then, after you get the loose ends worked out, finding local shops that will to touch a "Frankenstein" for general work can be difficult. I've had to become a pretty good shade-tree mechanic as a result. Whatever cost you think it will take to get the engine conversion completed, add $5-$10k in additional expenses. My LJ is a beast and very fun to drive but the investment in time and money was not worth it.

Hey I appreciate that info guys, that’s what I was worried about - engine adventures. I ended up putting a 3.6 back in it and sold it, along with a car, and got into a 392. It’s pretty great, life is good. Trying to work up the courage to go beat on it on local trails!Could not agree more! Everyone thinks these conversions are easy and cheap to do.

I think you might be the first person ever to say k series and torque for days in the same sentence. Typically a k series makes 30-40% less torque than horsepower and doesn’t make shit for power or torque below 3k rpm. Sure if you turn up the boost enough it will make more power than any of the stock offerings, but you’d have to push it well past 600 horsepower to match the torque of the 392 or diesel stock. Even then the torque would be too high in the rpm for technical trails, unless you go the Toyota build route and throw in a doubler. Not the route I’d go in a Jeep build, but to each his own.Stroked and built K series Honda 4cyl Turbo. Great fuel economy, amazing reliability, easy to acquire, and power/torque for days. You will need a standalone ecu.
