Big cam small turbo
 

Was wondering if anyone knows if there's I'll effects from installing a large cam on a small turbo set up. I only have money for the cam and plan to do the turbo later. Just wanna make sure running a 188/220 with a he351 if anything bad or whatever may result. Since the cams recommended for a 62mm smallest

Just remember when you flow more air through the motor the turbo must spin faster to make the same amount of boost. In other words realize overspeed can be an issue

Thanks, kinda what I figured. I'll just be careful probably. I don't really wanna spend the time to rig up a wastegate actuator for the he351 but I may.

Causes a bunch of drive pressure and can spie cylinder pressures and "COULD" lead to a HG failure in wost case ....

I wish I could afford to do the turbo and the cam at the same time but unfortunately I think I'll be redoing my hg and getting everything sized a bit better for the cam and pay someone to install it and the hg for me which will kind suck my budget dry for summer, aswell I'm swapping to a s400 frame which isn't exactly drop in to a cummins swapped Chevy aswell as going to a 2nd gen steed speed manifold from my 3rd gen bd. so it's gonna cost at least 2-2500 for the turbo set up and 2-2500 ish to finish the cam install and for the extra parts I need. Just figure the cam will be more time and work so might aswell do it first kuz the turbo swap is more or less a weekend project, just gotta make some intercooler pipe and a new down pipe.
