Inliners International Forums General Discussion Vortec 4200 270+ HP inline for $500 or less -- LINKS FIXED

He351 is just an updated HX35. It's a sweet turbo, but doesn't flow enough for a 4.2 Might work for a 250 though. I was looking at the HE431Ve (I think) before I found the duramax unit. Really nice turbo, but I didn't want to screw around with the CAN controller. The updated duramax units use good ol' PWM control. You could control that with a throttle position sensor and a 555 timer circuit - wait, which board is this?
