Well I'll take a shot at this.
A stroker Chinese crank (3.625) is about $700 bucks; good rods are around $600 bucks. You will need good pistons anyway so a set of custom ones will be around $700-800. You would also need to internally balance the rotating assembly $300 bucks. You would also need a neutral balanced fly wheel and balancer that can run around 500-600 depends on the brand or can buy the CAT neutral balanced fly wheel from Full Throttle for about 70 bucks and find your self a BMS hub for about $100 bucks instead of the BHJ balancer and the JW fly wheel. The engine builder is going have to clearance the rod/block for the stroke clearance.
I am sure there will be additional cost as for any high performance builds but you get the idea. This will give you anywhere in the neighbor hood of 270-274 cu depending up on your bore size.
You may also want to do some research on your compression ratio, I think the stock set up was like 8:1, I built mine to 9:1 and I see a lot of people are going well over 9.5: 1 on their 109 stroked turbo motors.
Just like anything else, you’re only strong as your weakest link, in this case if you get all the good internals, your weakest link would be your block.
We have made over 600+ rear wheel HP with a production 291 block with a GT 42/76 turbo and have gone 10.009@ 132mph. So in your case you will be fine.
