SE 113 Bigger Bore Cylinders

[scsmall]

I've been asking a lot of questions about my build because its only a few weeks away from going under the knife. I have the SE 103 kit shown. I am adding a Woods TW6HG, thundermax, having the heads worked on.

What would I need to do to have the SE 113 Bigger bore cylinders, pistons work with this kit? DO I need to bore the case? Or am I able to take what I have and just buy new pistons/those cylinders and change nothing else and get the extra 10 inches?

Also I know the crank isnt the best thing out there but if i do stay with the 103" inch, say get 105 hp/120 tq with what I am doing to the motor, does it still risk being ruined by not having it worked? Can someone PM a price idea for what darkhorse charges to do what everyone seams to be recommending? I live in canada and am hesitant to do these cross boarder type transfers.

case boring is necessary for the 113 motor . some builders are boring stock cylinders to 107 and axtell has 107 jugs that can be done without case boring , thats about as big as you can hope for. rons performance in hanceville alabama is doing cranks now and i hear good things about him , just a weld and true shouldnt cost a arm and a leg .

Ya I was hoping to avoid the case bore. My builder says he will do it, but he wont warrenty it because he doesnt feel there is much room to do it. So if 107 is the biggest I can get without a case bore, then I guess I just need the cylinders bored and a 107 piston purchased? I wonder what type of pistons I need for a 107 fit using the cylinders I have.

contact hillside , he routinely does 107 builds and knows exactly what you will need.

Stock cases have been used for builds of 124" & 131", with the 131 being the max. A 113" is no problem for stock cases, however you will lose the cylinder base o-ring and have to go to regular base gaskets. I've had a 113" for 3 years and no problems so far. Whatever build you choose do yourself a favor and get a Timken conversion done.

You need a new builder!!!!If he can't warranty that case boring then he's not confident in his ability to build a motor.Package the motor and have a site vendor ,Hillside, or Hyperformance do the work for you!!!It will be done right & you will be pleased

If you are going to do the case bore, do it right and install the timken bearings for the crank. You are usually better off to have a good indy shop do the deed, rather than the dealer. Some of the aftermarket barrels have a different base and are better for a big bore build.

The 107 is a little better than the 103, but you can get a lot out of that 103 without changing pistons or barrels. check with some of our sponsers, they can get 30/30 more, easily by doing headwork(which you need anyway), cams, the right exhaust and air cleaner, and or course, the proper tune. That 103 will be a whole different engine and a lot of fun.
