96 to 103 questions
i have the opportunity to pick up the top end off a 2016 103 that has 100 miles on it. It would be the heads, jugs, and pistons for $500...which I think is a pretty good price.
This would be getting installed onto my 2009 96.
If im not mistaken, this should be a straight forward install correct? Will I be able to reuse my stock throttle body, and is there anything I should know?
I’m guessing this essentially makes my 96 a 103?

I was planning on the easy start cams (makes the hot starts here in Fl easier), and unfortunately will have to buy a new tuner...it was tuned by the previous owner for how it's set up now, but I never got the tuner when I bought it. if there's no difference in the heads, i may sell them to recoup some cash and put that towards the cams.

🙄 I was trying to keep myself on a budget, that’s why I’m looking at these 103 parts. I originally wanted a 107 kit, but this kit is half the price (more than half if I wind up selling the heads) and from what I understand the gains with the 107 as opposed to the 103 aren’t that much bigger.

Also, I would consider going with a .30 head gasket as opposed to the stock gasket. The '16 Rushmore motors were running 9.7:1 compression. Dropping to a .30 gasket would get you close to 9.9:1 at no additional cost.
Depending on the cams you select for not a lot of money you could have another .005 or .010 decked off the heads or juggs to get you closer to 10.3:1 or 10.4:1. You would need adjustable push rods if you went this route but the bump in compression is where you are going to make significant gains in HP and TQ

I was waiting for someone to chime in that unless you increase the compression, the gains will be fairly moderate.
I'm still with stock 96 inches (13k miles), but won't do the pistons and jugs unless I can increase the compression to 10.25 or 10.5:1 to see (and feel) good bang for the buck gains.
Take a look at Fuel Moto's site with regards to all the dyno graphs of various 96 and 103" combos. You'll see a more torque with the 103, but still probably around 95-100hp with stock compression.
I'm not an expert by any stretch, but I've been researching my next upgrade from 96", and it seems the compression is more important than the cubes in terms of performance gains.
