Will 369sxe spool good with a 5 speed 3.55 with 250 100s or would I be better off with 366sex?

The 369 will spool up pretty close but in all honesty the 366 will be a little quicker for your M/T! I would suggest the 366 for more of a street truck and the 369 for all out top end power.

I have the ZF5 and 3.55s my setup is a little different then most as I feed my 369 with a blower which helps when the turbo is not spooled up. The 369 was slower to spool than a stock turbo but kicks ass when it kicks in. I had a blown boot of the inlet side of the turbo which was bleeding off all blower boost. I drove the truck on a few trips like that and the S369 is definitely lazy below 2K rpms but I do have the 1.0 housing. If your using the truck as a street truck I would possible try the .91 housing. I had to make tuning changes to spool the turbo when I upgraded from a stock turbo with the 350/200 injectors pulled back to the mid 300s for the street.

I have 238/100s, zf6, 3.73s, and a 366sxe with a 1.0 housing. Super quick spool up, great top end. 1:1 boost:back pressure up to 40 psi. I wouldn't change a thing in my setup. Perfect towing machine too. I DD My second hottest file, and only put it in the highest for being dumb. My second hottest file will not exceed 1200* in any situation.
