Being that this is a front engine car designed for ~225 rear tires, can it even put power down? I understand a delicate foot will be needed, but is it just pointless? There is also a weight penalty of about 200lbs, and it doubles the overall cost.
Another engine I was thinking about is the honda s2000 engine, which weighs on par with the Miata engine but has 240hp. And can be supercharged (assuming it would fit) to over 400. No torque though (seriously like 130ft/lbs at the wheels stock), and a custom subframe would need to be fabricated, steering rack moved, etc.
I really don't like turbo engines so trying to look at other options.

A few of us are hoping the Ecotec will be an option for us, as it is in a Miata now.... www.ecotecmiata.ca/ |

I'm running 245s on my car. They hold the power really well.
Sometimes I think I should have gone LFX instead of the FM2 setup but... The car is still a joy.

Several LSX cars running around. Dietcoke has had good success with hooking his up. And Bob from racingtheexocet.com has been having a blast on the track with his. XP5 has several video's out there and they run either BFG Rivals or 225 Hoosiers. You can get a 275 Hoosier on the car with a wheel spacer.
It's a personal preference on what engine you run. That's the great thing about the Exocet as long as you can get it to fit between the frame rails anything goes. Just takes planning and a little fabrication.

As others have pointed out, there are a bunch of successful V8 Exocets running now. One of the local time trial guys is running a LS Stalker, essentially a similar car to the Exocet, and he's usually in the hunt for the quickest time of the day. Our car has been running well for a year, so it's time to break it, and I think I'm headed to a Honda K20. This will keep it in 2L classes for time trials and autocross and should be good for around 250HP, which in my estimation should be enough to be plenty amusing, while actually being lighter and so improving the F/R balance. The car is fast and a lot of fun now with the nearly stock 1.8L motor. kmiata.com/ |

Let me oversimplify it: On the autox course I don't think the power is any particular advantage over a 200-250hp exocet that may turn a very short course in a similar time due to a small weight advantage allowing for faster low speed corners and transitions.
On the road course, not only am I immensely faster everywhere, I can run ridiculously more aggressive aero settings, and not run out of steam to push the car down a long straight. It's win/win.
Plus v8 noises.
The ls's biggest weakness is oil control, and that's something you have to plan for and address. I run 275 hoosiers all around, and they fit-ish under the exomotive fenders.

I'm intrigued by the EcoTec option. Any reason it wouldn't work in a exocet if it will bolt up to the Miata subframes and transmission?

It fits. I've seen two cars with ecotecs in them.

Did you try the Flyin Miata v8 oil pan, or did you go straight to the accusump? Also what gear are you able to give it full throttle and not break traction, 3rd or maybe 4th I'm guessing? |

No oil pan is going to hold oil against a pickup in a corner. It all just ends up in the top end of the motor. 2nd gear holds power just fine.

Yeah I didn't think about the fact that the gearing is way different from a Miata engined Exocet. Did you make an attempt to fit the body work as standard, instead of cutting the hood portion off? It looks like the throttle body interferes. this one is running one but the front of the bodywork is sitting pretty high  The engine is a lot shorter without the plastic covers most people have.  |

It fits, I have a nosecone and a full hood that I run for different events (nosecone makes it a TON easier to work on the car). The high points are the oil dipstick and oil fill, both of which have to be shortened.

A few of us are hoping the Ecotec will be an option for us, as it is in a Miata now.... www.ecotecmiata.ca/ Oddly enough, I just had a short conversation with Ecotec Miata this week about what might be required to install an LTG motor using their swap bits. Afterward, I'm pretty sold on the LE5 (2.4L) Ecotec to replace my Mazda motor when it finally blows up. Apparently they take boost really well and the turbo parts from the LNF (2.0L) will bolt right up ot the LE5 with few if any fitment issues. |

There's one big problem with using any other engine in the BP drive train.....the drive train. It's just not durable once you get into the 250 - 300+ range. Considering its form a car that was released with half the power you are putting down its pretty good but I'm not a fan of disposable drive trains.
