    Came across this a few days ago and to be honest Im quite interested, and compared to the other options for a large increase in power, this is pretty good deal.

    http://www.todaracingusa.com/ferrari.htm

    Turbo charging is a no go for me, Ive had high power turbo cars before and they've all at somepoint blown a rod, or mashed thier bearings, and to turbo charge a hi-comp motor like the 355 just screams "DETONATION", same for super chargers.

    But an N/A stroker kit is a difference kettle of fish, you'll still have the responsiveness, and urgency, and best off all, a very reduced risk of detonation!

    So, does anyone know of a car running this stroker kit?

    It claims 491PS for the most aggressive kit, which would be a hoot, yet they dont seem to mention anything about exhausts or intake mods....so Im assuming those figures are based on everything else stock.

    If thats correct, then with headers, cats, mufflers, intakes, flywheel etc, you could well be looking at a good 530+hp at the crank.

    A real weapon..no doubt about it!

    Yeah if you buy from Japan its about 20ish-k plus then you need to get it fitted, I still think its not bad value.

    Considering a Gruppe-M intake will cost ya 3 grand for 10hp, or a decent exhaust setup similar money and gains, then 30k is still ok.

    I will PM you regarding the GruppeM

    Keep in mind the 490hp kit has a 13.3:1 compression ratio, which won't work on pump gas.

    Even the lower hp kits up the compression to 12.0:1, which will give you a chance of detonation. Not as bad as forced induction, but either way you will need to adjust your timing to compensate.

    You could easily adapt a single turbo (low boost) kit that will make over 500hp for less than $20,000.

    hmmm good point about the compression ratio, you could run some water injection I guess at 75%+ WOT to keep the charge temps down on normal gas, but then you are getting into the same tricks as turbo charging anyway.

    Im just considering all options at the moment and the route to take.

    A well sized turbo, running 6-7psi, with a water to air intercooler and water/methanol injection (to bump up the octane when on boost), should be reliable. This way you wouldn't need to adjust the timing.

    A simple fuel computer like an Apexi S-AFC could minipulate the MAF signal and allow you to tune the air/fuel ratio.

    While I love turbocharging and have done so to many of my vehicles one must keep in mind that it does change the attitude of a car. Even a very responsive turbo setup still lacks the feel and throttle response of a naturally aspirated engine.

    Also, on a 355 intercooling would have to be air/water which is not ideal for a road course if the car will be used that way.

    Fwiw we run many 1150+rwhp turbo engines with 4in stroke, 4 to 4 1/8 bore and 7700+rpm = 5133fpm piston speed. They seem to be very reliable as we've had those combinations on the road/track for years now with no engine failure.

    Toda stroker has much lighter recip and would see 5019 fpm at 9k rpm.

    Not likely ideal but I wouldn't go so far as to say it would beat itself to death.

    As far as expensive, YES! Absolutely ridiculous.
