Best option to get more HP from ST202 (excl buying GT-Four), tl;dr: Like my ST202, want more HP, willing to spend 2-3k EUR. Options

I've had my car for a few years now and I really like it. I also know all its faults and I did quite a lot of work on it (repaint, interior etc.). However, the car is way too slow, be it just 170 HP or the horses that died since it was new. I think something around 250 HP should be enough to give it a bit more ooomph for a few more years (and avoid being chased by vans on the highway).

There are very few LHD GT-Fours in continental Europe so buying one is out of the question. I'm also not buying a different car because anything I'd like is in the 15k-20k EUR range. And I'm not willing to spend that much on a car with all the new issues that it'll bring.

So I'm willing to spend another 2-3k EUR to get more HP from te current car. What is the best option? Getting a 3SGTE, boosting the current engine, something else?

If I get 3SGTE, how much work is the swap? Since most engines are from RHD cars, are there any complications installing it into LHD?

Thanks for the links.

Well, with slow I didn't mean it's like REALLY slow but it's far from what I'd like it to be (not to mention how it looks).

If anybody else has any comments, please let me know.
