Second Gen Swap? FA24

[AutoNewb]

Hello all,

So the second gen was officially unveiled this morning. The first thing I thought of was engine swap.. I dont want to buy a new gen 86. There is just no need. However.. I have a full bolt on, e85 NA build. So just a tad over 200whp. Imagine the same on the FA24 which is estimated 228 crank hp ~191hp at the wheels. So.. how likely, how possible would it be for a FA24 swap. Will there be a need for a MOTEC? What are yall's thoughts on it?

Well... Maybe. A guy got a Honda K motor to run on the BRZ brain so it's certainly not impossible. It's unlikely to be 100%drop in but someone will make it work. They always do

I'm mostly excited/curious about the possibility of a hybrid swap like the EJ guys would do back in the day (2.5 block on 2.0 heads)

This is actually more likely to work because less stuff needs to work with the stock components

I think it would all depend on sensors used. If both engines have the same sensors it should be close to a direct swap. Especially if you can swap sensors over. We'll have to wait almost a year to see, really.

Considering 17+ engines are a PITA to swap into older cars I don't see it being simple to swap a FA24 into older cars.
It might get easier via kits if it has enough interest.

They also stated the engine is mounted lower. So, is that just new mounts or is there more to it? It might have physical issues as well as electrical / wiring ones.

At this point... WTF KNOWS!?!?!

Exactly. Fuel lines and stuff like that can be adapted easily. Sensors are the problem. There could be internal changes too. For instance on the LS engines, the wheel the crank sensor reads got changed at some point. You can just swap sensors physically but iirc you have to use a gm computer intended for that crank trigger, or a standalone that can be programmed for it. We will see soon I expect

While the gearhead in me says that swap would be sweet and probably not very complex. The practical side is questioning if the juice is worth the squeeze.

Unless it drops right in with minimal cost ,you're most likely best off with a forced induction system. I know it's not exactly the same but the LS swap was... Expensive.

Long as I can drop the 2.4 into my '13 FR-S.
Once I get the valve springs changed and gum spit into the oil passages I don't have much hope for the original engine.

FA24 might have the same problems

I could definitely see the 2.4L displacement being very responsive to boost. Yea the more I dig into the LS swap, the less I want it - but the cool factor is thru the roof.

[why?]

Heck i'd be willing to switch out everything, that new interior looks awesome. Engine, wiring harness, ecu, steering wheel etc all into the old car. I highly doubt it would be "worth it," but it might be fun.
