I think i would like to use a turbo around 300-350 to support future upgrades. I think i would also like to see faster response at lower RPMs but not completely lag when i step on it at 65mph, which seems to be the give and take of spooling.
Now the fuel plate, did you really get almost 100HP out of the fuel plate alone, or is my ignorance reading your "313/756" wrong? If i could get the same (i would like to know what fuel plate your using) that would put me in the 400 HP range. Do they make a turbo that you can run stock and reach that 400 HP range?
The term "+90HP injectors" is a worthless term. Injectors are described by hole size, number of holes and spray angle. For instance, 5X14, 45 degrees. Somewhere in the archives is a post that talks about the hole sizes of the stock injectors. There is no standard for "90 HP injectors".
I've used two fuel plates. A #11 with 16 degrees of timing put me at 297/611 and a custom ground plate designed for towing with 15 degrees of timing put me where I am at now. Increase timing-increase turbo lag. The custom plate was designed by a Bosch shop owner in Austin, TX (who tows an RV with his '96) and installed while my pump was there to fix an oil leak. You read it right, I've made no other changes. Actually, the plates produced well over 100 HP. The 215 rating is measured at the flywheel. The 313 was measured at the tires after drivetrain drag. I estimate flywheel HP/TQ is about 385 with over 900 TQ. IMO, that is why I went through 12 NV4500s which are rated at 440 TQ. HP costs money, be careful what you ask for.
They make lots of turbos, and I'm the last guy you want to ask for recommendations. I've never done the research since I'm happy with what I have. There are facts and opinions regarding turbos and compound turbos galore on the forum, most of them in the performance pages. The trick is to figure out which members are blowing smoke and which actually have a handle on the subject. If you PM me I'll tell you who I think fits those categories.
