I have all of my modifications in my signature. I know I need a turbo or two, and that will come once I can find a cheap HT3B for a twins set up with an HX40. I am looking to see what everyone else who has had or has what I have done to my truck should recommend. The one thing that I have to keep in mind is that I use this truck as a daily driver and work truck towing roughly 10k each time I go to a new job site so I like to keep the fuel economy as high as possible while keeping the EGT's down.

Any input is greatly appreciated.

Also, on my last dyno, without the timing and GSK I pulled 349 and 909. Anyone guesses as to what number would change to with those additions?

 

My one buddy had the same work done plus DV's and couple small pump tweeks and made 391 & 912 on his 97, now with a HTT 64-71-14 it went up to 488 & 1061. So I think you should run that HTT 64 (cause you still drive it)
and put some DV's in it and buy a set of new ERA 435's it get it over 500.

 

will the HTT 64 give me somewhat the same as twins? can you give me a link as to where I can purchase that turbo so I can check out some specs. A LOT of my towing is through mountains so I cannot wait to let that turbo light up. I need good low end boost. New era 435's are on my docket as well, but I've heard fuel economy is horrid with those. I am still able to get 19 with my 370's and 17 while towing.

 

and wow, the HTT 64 is gonna be more pricey than building a twins set up with an HT3B unless I can find a good used one.
