I don't care for that much power. I can do with 150 hp less. What I want to know is what the torque curve looks like.

Wouldnt go quite that far. But i guess its a matter of opinion

So, without supercharger, but with the others HKS parts we can get about 100hp extra from factory?

What do you think?

Did you watch the video? Or follow this forum cause I find it hard to believe you don't know that its a supercharged FA20 if you do

:D

I know this really doesn't matter to your point, but if they're tearing down the engine replacing pistons, connecting rods and possibly boring out the engine or whatever else, its going to be a lot more than $2k.

That 30k difference is more like less than 20k, maybe even less than 15k. :)

And who knows how reliable it is? I'd bet at this stage, not very.

Lol, I know. But it's fun to think about!

I would GLADLY spend $6k to bring power up to 394hp.

nice tail lights. but i would still go for the normal ones

4U-GSE! But yea...:thumbup:

I was just surprised to see some company using the actual engine.

FYI to all here.

This is NOT the standard bolt-on supercharger kit.

The engine has HKS forged internals, a mechanical TB, water/meth injection, etc. Looks like it is running 1 bar (14.7 psi) of boost.

A bolt-on kit will probably make 1/2 that much boost (due do the stock internals and high c/r) and like 50-70hp over stock.

Not a snowflake's chance in hell.

All the other parts are supporting mods that allow the supercharger to work to it's full potential. They don't make power on their own.


The TB is just there to meet Tech regulations. In motorsports, electronic throttle bodies are a no-go.
But you're right about the power levels of the standard kit. Preliminary info has it rated at ~250PS, though I forget whether that's at the wheels or not.

I know all these ej25 swaps were making me depressed

HKS using the FA20 is a refreshing change

So if I read this right, HKS Supercharger kit + fuel pump + clutch + con-rods + pistons + ECU + head gasket + full exhaust + unknown numbers of wheelbarrows full of money = 397 HP. I look forward to the more modest setup to see what the stock long-block can support safely.
