Default Turbo sizing for 402

I've been having belt issues since I've received the car from a new engine. My ECS blower keeps eating up the belts, and so far I've replaced the tensioner 3x in a matter of 2-3 months. Not even 200-300 miles. It's going back to the shop....

If it keeps happening, I'm doing the swap and going Twins. Probably going to AGP TT. Would 62/62 be just right for my 402 and will this cam work (this is in my car)? CAM 22X/24X, .619/.617, 113 LSA

If all fails, then that's what I'm going to do. Doesn't make sense though. I've talked to a lot of different people who's had the same setup and been running the same belt etc for 3 years.

How much power are you looking for? Ive been debating on getting a f1x $5,500 for the head unit alone, or going with a twin turbo setup. I think 62’s are gonna spool quick on a 402 and you might get 900’s out of them but they’ll be maxed around there. If you want more you’ll have to go with 66’s and up. Forced Performance has an amazing bb 3582 for $799 https://www.forcedperformance.shop/products/hd3582-ball-bearing-street-turbocharger

You'll get more than 900 out of 62's.
