    If you could get some definitive information on this stroker and what it entails that would be great. I have inquired via email and phone about this kit but the information was very vague and nebulus.

    I have a hard time eating $8,000+ for the other stroker rotating assembly when running OEM long blocks can be had for less than half.

    If you do find out @bigjae1976 , please share.

    Rebello and Sunbelt used to be "the" engines used in Speed World Challenge cars from the early 2000s onwards.

    So what should I ask? Not sure what information is meaningful. I could ask things like "Does it look pretty?" or "How does it taste?" but I don't think that would help. Click here to enlarge

    No worries dude.

    I could not get a straight answer on the stroke. Last word I gathered was the cc gain was NOT made via the crank.

    I just wanted a parts list with specs and couldn't get it (2010).

    I mean...what would make this stuff quality? What accounts for the price difference between the $8k kit?

    The exchange on the crank is the give-away.

    Pistons may be the same, but I suspect the rods are different.

    The crank for the $8k kit may be a dedicated forging and the other kit may use a welded and re-ground crank.

    Just my ideas, may not actually be fact.

    Personally, if I was going to do a stroker, I'd want a dedicated crank forging. (One off)

    Good points. I'm sure they are reusing our cores...didn't think about that.

    Thanks!

    The main difference is the VAC exclusive 3.5L crank made by Arrow Precision. There is no finer S54 crank in the world Click here to enlarge Also, we use CP Forged Pistons and Arrow Precision Forged conrods in our base kit. Not sure there is a finer S54 rod on the market either.

    I'm not familiar with them for this application although the name used to be big. When showing me parts like this at this cost though I expect to see a dynograph and video of them actually in an application.

    Who makes it though? Just curious but seems the last thing my build needs is more power or torque right now.

    Rebello's kit, based on the photos and the price, would appear to be using OEM crankshafts reground with offset journals. Based on the fact that the rod bearing has a hole in it I'd imagine they are using a Honda rod journal. If that's the case you're looking at gaining 2mm to 3mm of stroke, nothing too significant. Looks like a chinese rod in the photo from Eagle or the other manufacturer, those cost less than 100 per rod. Crankshaft grinding usually costs somewhere between 800 and 1000, and a custom piston set at 175 a piece lets say. Grand total of about 2800 bucks if you add in the cost of rod bearings.

    The major cost in a stroker kit is in the crankshaft, which typically is ground from billet 4130. That alone is already a significant improvement over an OEM forged crankshaft. Billet crankshafts are typically pounds lighter than OEM cranks with better strength. On the S54 you're gaining somewhere around 6mm of stroke. Cost on a billet crankshaft alone for most of the inline 6 motors tends to run around 3600 in this area, that's what the majority of the price jump is attributed to.

    fyi, metric mechanic offset grind S54 cranks to 93mm for their M50/52/S52 engines. the S54 bearing being 51mm vs 46mm for the M52/S52 rods makes it a common size bearing but length still is off but easy enough to fix that with a custom rod and piston comp

    there arent many S52/M5x engines worth turning past 8k so a smaller bearing is fine but not so much on the S54 i would think.
