Hello all. If you were given the choice of doing performance upgrades to your 110" ( cams, headwork, Tune, TB etc) or for the same or small price increase you could have a 113" would you do it and if yes why?

More cubes is always better!

IMHO going from 110 to 113 just for the sake of doing it isn't buying you much of anything. Now if your going to do lots of work like port the heads, camshaft, change compression ratio, plus the exhaust and intake modifications it might be worth it.

Steve I am glad you pointed that out.  The upgrades you mentioned are going to be part of the build. Just didn't know if the extra 3 CI" in addition to the items you mentioned make a noticeable difference?

If it's already a 110, I wouldn't waste the money to disassemble and bore just to get 3cid. 

If it were an 88, 95, 103, then I would go to 113.  The reason I prefer 113 over 110 is the base gasket instead of an o-ring. 

Once it's a 110 with an o-ring, you can't bore to 113 because the o-ring groove will not be removed completely and will leave a poor sealing surface for the base gasket of the 113.

It is a 110 now.

[Ed Ramberger - One_Screamin_Eagle]

It is a 110 now.

Yes - that's why you can't go to 113 and have a reliable base seal, and even if you could it would be a waste of money to disassemble and bore.

when i did mine, i only took it out .005 over, that was all that was needed to clean it up. im old school...more is better when it comes to cylinder walls 

[Steve Cole]

Like others have said, your opening a new set of problems if not done properly and the truth of the matter is your not going to gain much if anything over a 110 done with the same parts.

[INDEPENDENT_1]

I concur with Steve's and Ed's sentiments. Unless the cylinders are only salvageable or unless the crank has got to come out and unless you intend to do the things Steve mentioned to increase performance, I don't see the advantage really. It's basically the same way I feel about taking a 103" to a 107". Unless forged pistons are needed for the added compression, I don't see the need.

[firefighter156]

Thank you for the feedback.

Seems like a lot of money for an extra 3 cubic inches. I personally would do the other motor Hop up. If you were going to 117 it would be worth the added expense. Just my opinion.

There's a lot more to it than 3 cubic inches.

When the stock CVO 110 barrel is bored .060 over you have a 113. Its a bolt on. Nothing has changed with the O ring that seals the bottom of the barrel. The cases do not need to be bored, split or anything. It reassembles like stock. When your trying to build decent power nothing beats a professionally bored and prepped set of barrels that will supply proper ring seal. Something the stock barrels are not always known for. There are many reports of less than spectacular OEM machine jobs on stock barrels. Fresh bore, 3 cubic inches and last but not least a healthy compression increase will do wonders for power. The .060 SE pistons that I just bought for my CVO are 10.5 to 1. After I CC, deck the heads and calc it out I should be in the 10-6 to 10-7 range. The compression increase changes  your cam choices big time. I'm going with a Tman 625 or 660, still deciding. Either cam will make monster TQ with comp in the 10-5 range. Lots of other cam choices too.The power difference between a 110 with lower compression and a smaller cam VS the 113 with 10-5 compression and a bigger cam is huge. Over 10 points on HP and TQ easy. Its not just about 3 cubes, it's the package you can build around it.

Steve is hitting the nail on the head! 'Can be done for about the same $ as a 110 Build.

A no brainer for me (especially, boring the cylinders properly).
