lets see how well my memory serves me if I remember correctly there were quite few similarites between the motor they are putting in there and the b series motors same bore same stroke dohc vtec etc. Also the turbo motor you are refering to either hte engine designation or model of the jet ski something on there has some numbers followed by the good ole letter and number combination T and 3 you read that right T3. Now Im just guessing hte letter and number T3 that I saw is in reference to the turbo being a t-3 turbo on a b series motor hmmm interesting. If I could find the article to clear up some of this speculation it would be just great.
