So check my build which has a target of 500+ whilst remaining NA, but it is a full-race build based on JWT parts, non-VVEL heads which are mega CNC ported,

The new engine will go into the car after Xmas as we are only just now about to start the OEM engine with a Motec M150 tomorrow (7 Dec). When we have the M150 running the EM engine, we'll install the new beastie and see where we get to. The heads have sufficient flow to make just over 500 at the crank but it remains to be seen whether we can actually get that Investment to date is 5 figures starting with a 2 ........ it is NOT cheap. Be very careful what you wish for. Best you speak with Clark Steppler or Ben Pila at JWT BGTV8 VQ40HRGA Race engine build |

Ok, this is definitely looking to be more than I anticipated. In my list of parts that I've compiled thus far, I had about $13k figured, but I thought that was a fairly safe estimation to cover everything.
I can't wrap my head around $20k plus for this. I sort of assumed that considering this wasn't going to be a high power build, I could keep the stock pistons. I know the rods would have to change to allow for the longer stroke, but I certainly didn't anticipate swapping at least half the internals.

Who should I contact about the crankshaft? I know there's a horror story or 2 floating around about the BC kit, but is that a recurring issue or was that 1 off problem from an otherwise reputable and trustworthy manufacturer?

Update: I called MA Motorsports last week and talked with Daelen for 20 minutes or so and explained what I was thinking. He confirmed that on pump gas, there's just not much to be had with the extra displacement, especially when compared to the cost of the build. He did tell me it may very well be worth it if I could switch to e85 and raise compression to around the 12.5 mark, but that's not an option for me as the closest gas station with e85 is an hour or so away.
So, with that said, I have ART pipes in my spare bedroom and waiting on my exhaust. I'll be heading to Z1 just after the 1st of the year for install and tune, then on to saving the pennies for the suckerpunch oil pump and the JWT C2 cams.
