decision.....HTT 64/71/13ss or 66/71/13ss???

Keep the 62..... Most guys go too large with turbos and give up lowend (which is what we really feel on the street). A 62mm will yeild 600 RWHp with no problem on a CR truck. The 64 is a nice turbo but it is slower to spool and the HP increase (especially with you current setup) isn't a lot different. The 66 is really a competition turbo and while some use it on the street and are happy lowend suffers and you are prone to surgine especially while towing.

I have run the 62, 64, and 66 in both a 65mm and 71mm turbine by II and HTT. Out of all the turbos the HTT62/71/SS is my favorite.

I have the 64 on my truck and didn't notice but maybe 200 rpm difference on spool up with just running the smarty. Just my 2 cents.
