No. They are different. You can get a LS flywheel from Jegs for $99.

yeah I was looking at that. is jegs one really much different than the stock ones? I know I dont want to run a lightweight flywheel...lol

I don't know that they are any different, just much easier to find.
I've actually been thinking about some light flywheels on mine...

see I was worried about a lightweight flywheel not having enough momentum. I've done a lot of 4 wheeling over the years and with big heavy tires having a light flywheel can hurt performance. yes you gain in the top end but it can stall the motor when you hit heavy resistance. Thats my concern with a boat. you have so much reistance with the water that I would worry about stalling out whenever you changed gears. I know in small engines, I use to race a honda civic... dont laugh to hard on that one... but with the small motor if you did any road racing any increase in corse elevation would actually slow the motor down. it just didnt have the momentum to keep the rpm's up. I would talk to haxby speed or bob madara and see their thoughts on flywheels. On a smaller lighter boat it may not be as big an issue on say like a 32' or bigger boat. I honestly dont know how it would affect the engine on a boat, I'm just going off of what I have delt with in the auto world.

so talked to Bob Madara and he said that the lightweigh flywheel isnt a bad idea in lighter boats. Like I said the flywheel is an energy storage device, but he stated that instead of storing that energy the lighter flywheel allows it to be directly applied to the propeller. he said it really helps pulling out of turns and also instead of making the bow point to the sky when getting on plain it helps to get the boat on top of the water faster. good info, so it looks like I'll get getting an aluminum flywheel for my engine. I gotta give a big thank you to both Haxby Speed and Bob Madara. you guys are simply awesome. I don't think this project would be near what it is without the help I have recieved from them.

okay so I just ordered a fidanza 12.5 lbs aluminum flywheel so I'll report back on how well it works... LOL gotta love amazon... so much stuff on there. Also anyone keeping track this swap is not for the faint of heart. by the time I have the headers for this monster I will be around $8300 invested in the engine. all for a boat I paid $2000...hahahaha. could this swap be done cheaper? absolutely. I just chose to go with the better option of investing money into it the first time.

Exciting new developments on the LS front.

gotta love twins... lol I'm planning a single turbo ls for my bmw swap thats coming as soon as i have my boat running. i love boosted ls engines. the 5.3's love boost, and can support a damn good amount of HP in stock form.

Motor mount adapter plus coil relocation. Brand new to the market and straight from haxby speed. These things look killer and its about time some one has made something like this. If anyone wants more info contact alex at haxby speed.
