    Default My Sexy 1992 21 Sunsport


    I'm the only the second owner of this boat and it's in show room condition. My wife and I have had it for over a year now and we absolutely love it.

    I upgraded my sound system by installing all Polk Momo component speakers front and back with individual crossovers all powered by an Alpine v1200 six channel amp and matching Alpine mp3 ready head deck with three pre-outs. Everything looks completely stock. And, it sounds incredible!


    This is the Pleasurecraft PTI Boss GT-40. It's a full roller engine. I also ported the heads and installed 64 cfm exhaust and 61 cfm intake valves. I upgraded my carb a little. It's a Holley 4010 750 double pumper(found the correct info) with upgraded power valves, jetting, and vacuum secondary pull-off. I'm pulling 52 mph @ 5200 rpm with a 14 X 16 1.02 cup 3-blade. The collector is stock with traps at the collector outlets rather than at the transom. It sounds soooo hot!

    It would be safest for me to say that they're both sexy!

    Post the picssssss! I bet the system sounds great! Engine mods are incredible! My 87 SS goes about 42 wot with a 13x12 3-blade with the stock 351. My carb is a bit off now it gives me some blowback when we are weighted. I'm thinking I need a re-pitched prop to raise rpms.

    Let me know if the pictures are not appearing... I can still view them even when I'm not logged on, so they should appear on this thread...
    Also with your 351--assuming it's the pcm 351 base motor, you can bolt on the GT-40 cast Iron heads (not the GT-40"P" heads), and they will litterally bolt right on with out modification. The spark plug location and manifold bolt pattern is exactly the same. You will have to rebuild your carb and jet it up probably two jet sizes or more. It is an instant 44horse and 400+ rpm upgrade.

    I see them now! Wow! Beauty! Upgrade for motor sounds nice but I have so many things on my list. How much would something like that cost?

    You should be able to find heads for around 400 to 600 bucks. Check Ebay, forums, craig's list, etc. And make sure you get pics of the stamping on the heads. they're meatier and gt-40 heads will have the "gt" stamp on the corner of the heads and three hash lines on the opposite corners; and gt-40p heads will have four hash lines on the opposite corners. This will help identify the heads properly.
