I’m shooting for around 400whp and I’m wondering if I’ll need a built head or my stock head and block is good enough. I want to be over 400whp but under 450whp as I’ve heard that’s where a lot of stock parts start to break.
My turbo started making a weird sound since yesterday, I was even driving fast when I heard it. Whenever I build up boost and shifts it makes a air compressor sound like a pssss sound if that makes. It’s not the usual sound that my turbo makes. Any idea what’s wrong?
