Verified Buyer
Almost a 5. But one fatal flaw
Rich | November 7th, 2023
I bought these pistons a little more than a year ago. And they are quality. Only problem is they come with paper thin wrist pins. I called wiseco and they said they are rated for 400 hp. Times have changed. People are seeing 600 on a stock setup, I asked them what I can do and they said I can get their tool steel turbo pins. Which will hold anything I put at em. Which I did. For an additional 120 bucks. If you want something great these are it. But if your looking to make any power above an NA setup. You'll need to get their pins. Which is a big slap to the face considering everyone else has caught up with the times and includes them at a price point cheaper than the wisecos without.
