Hey guys im in the process of building a 2.3l will i need to get head work to support my 700hp goal using a 6466? i have kelford 272s installed at the moment but wanting to know if i need to get head work done.

thanks

 

That turbo shines at 850ish+, u can take a 6266 to 800ish + too... And no don't port the head and no oversized valves, u could probably do a mild deburr but thats about it...

 

It can also be done with the much smaller 6062 if you are shooting for a better spool.
I have had my 6466 for a few years now and its a great combo with a 2.3L. Great street turbo if you are shooting for 800+

A lot of wheelspin but a ton of fun !!

 

Your probably going to need more than head work
