The turbo that makes the most reliable HP out of them all of course ;). Now, to find that out, you must buy all the PNP turbos and their individual options, install each and dyno each. That will let you know which is best. You can ship me the spare ones you'll have left over, I'll find a home...
Mine comes with a removable silencer too, but no option of a resonator is offered. My exhaust wasn't mean to be civil on the streets as it's geared towards off road vehicles ;)
The blowing through balloon with a straw vs. a garden hose is a good example of critical velocity being reached. Let's say instead of the garden hose, let's switch it with a 2" pipe (assuming the balloon will fit around the end) It's going to take you longer to fill up that balloon because you...
Also, you should be loosing only about 1 psi on 2.5 piping from your turbo to the intake mani, but there are other factors to include, but that should be damn close.
Jake, even running 20 psi with the smallest diameter piping being 2.75" and at 6000 RPMs is only going to give you a mean velocity of about 238 ft/sec, well below critical velocity (300ft/sec) which is where you want it to be at in the peak power point on your engine's setup. Honestly, I would...
Have you bought the cooleeze piping already? there are two versions of it, one's for the '87 and the rest are for the newer design IC (it may have been '88 and down though, not sure exactly...)
If you're not pulling the pan, do it IJ.'s way, to take an impact gun, hit the bolt with some PB blaster, and tap the impact gun in short bursts on the bolt until it loosens up.
He may want to rethink the 3" IC piping though... Depends on how much boost he actually plans to run though when it's all said and done. Read this Jake: http://www.supramania.com/forums/showthread.php?t=44148
6 quarts of 0W-30 or 5W-30 oil will be just fine and no worries of it having too much oil in the engine at 6 quarts. A good practice is to keep 1 quart over in this engine. It takes a little more than 7 quarts of oil in the engine on the stock oil pan before you have to start worrying about the...
Jake, based on that compressor map, the best sweet spot for your turbo will start at about 8psi at 3750 RPMs and still be within it's best efficiency island at 12psi at 6000 RPM's. That's where I would start yourself at right off the bat with your turbo. That thing should be a beast at 12 psi up...
I have a chrome moly flywheel that's 12 lbs. but it's from XTD. I've also got their stage 3 clutch, but that's a completely different story... :3d_frown:
