Thanks for the info.

Based on that I'd guess the conversion will add 200 - 300 pounds possibly a little more. Still a good trade off as you are just about doubling the HP.

I think the stock Boxster S is carrying about 11- 12 pounds per HP - the converted car should be in the 6 - 7 pound per HP range all things being equal.

Thanks, hopefully the haters stay away, this build is definitely not for the purist! You will probably have to weigh everything individually to know the exact number... i'll just weigh the car after I'm done, which will be done on corner balancing scales~

All told probably 250-300 is a good guess as the LS3 motor is right at 500 lbs itself... add the kit and I can definitely see about +300~ or so.

I LIKE THIS VERY MUCH

My internet has been giving me crap the last 2 days so I am re-uploading the longer version video I made and hopefully it will work this time. If so it will be available here in about 2 hours or so - http://youtu.be/ixPZD731alM

I made 2 more quick videos today which i'll try and upload as well. Pulled the motor back out and put the intake manifold on, tried to tuck it in and not enough room so I pulled it back out and got the cutting saw out again. I trimmed away all the excess metal underneath the center lock latch for the engine cover and it got me another half inch or so but more room is still needed.

I also went ahead and trimmed up the back of the compartment to make room for the throttle body and MAF stuffs. There is not really as much structure back there as I thought, just pulled the foam out of the way and basically made 3 cuts and whacked a large area off to make sure I have plenty of room. i'll post the videos after this long one finishes

Thanks!

With the extra weight in the middle, it should have less negative effect than if it was in the front or back. I know a guy locally that's sticking an iron block 6.0 in his boxster. He also plans on throwing some turbos on it!!.
