Looking to do some mods. Looking for some input

[Destroyer]

Right now I have my 2012 pro rmk 800 155 all stock. If i don't get a new sled I'm looking to maybe stretch it out to a 163 and do some other mods. If I get longer ice age rails would the rest of the rear skid work? Or are the 163 components different?

So this is what I'm after. I want to know what everyone thinks I should put on.
Chassis
-163 ice age rails or complete skid
-new track
-probably need new drivers
-Tunnel extension
-New shocks Front and back
-already have alternative impact a arms
-Have feethooker running boards

Motor
either big bore or boost it turbo kit. I like to jump alot and need awesome throttle response. Do not want to sacrifice that at all. I will ride it stock before giving that up.

If you like to jump a lot, stretching out to a 163" is probably not the best way to spend your money.

I could be wrong but it would probably be more cost/time effective to sell your 155 and buy a 163. Just my 2 cents

I thought i should just buy a 162 maybe. But I already have the running boards a arms. and bad ass wrap. I need a track anyways. Mines pretty wrecked and the stock poo track sucks ass in spring snow. I straightened my rails a couple times. So some stronger ones would be a good idea. A tunnel extension is maybe $200.00 and a stronger bumper is a must for the pro. I have no problem launching the 155. I think I could handle the 163.
