VG33E Turbo Build Parts- I've Put Together and Linked a List For Future Reference

[Snowboarder12345]

So as I've been in camp for the last 2.5 weeks and all the rec stuff has been locked down due to a really sh*tty (no pun intended) virus taking up residence within it, and I would have done it anyways by next winter for when I could actually do the work, I have created as thorough of a parts list as I possibly can for my ideal turbo build. I'm looking for 300hp ish at the crank and ideally I would like to be running 8-10lbs of boost. I'd like to be seeing peak boost levels lower down in the rpm range (1500-1750rpm), seeing as it'd be more useful for a 4x4. I've been doing a ton of reading for a few months now on the subject, and have been into every forum and topic I can find on the subject. I've also done all the turbo math and checked maps and all that jazz. I'm just hoping to tap into a little more knowledge than I have as I have never actually turboed an NA gas vehicle, I just have a little knowledge that comes from owning and having plans for an old diesel truck lol. I'm hoping someone who knows more about this stuff can maybe go through this and give me their take on it, both in terms of the build parameters itself and the quality of all of the parts I have listed. I have obviously tried to keep costs to a minimum without making major sacrifices with quality (no eBay turbo kits here!). I think the biggest concern I have right now is whether or not would be possible to be making that much boost by that rpm range, without making a bunch of boost at idle. Electric boost control perhaps? Link to the spreadsheet below. I have links to every part in the spreadsheet, and I have tried to keep it to as few online vendors as possible to make it easier and potentially help with shipping costs.

Yes, I have also looked at doing a 3.4L, or a VG33E+R. I have a bunch of links and stuff saved, maybe I'll compile all of that stuff into their own spreadsheets next rotation if the camp is in lockdown mode again and I'm bored.

I have been thinking of the same thing, but I do not have a problem with the cheap ebay turbos. I have a friend that makes turbo kits for Polaris Razors and he told me twin very small turbos would be best for boost at lower RPM's. The smaller turbos spool faster. He also said leave the compression at stock levels since the higher exhaust pressure would spool the turbos quicker. Lower compression is for engines that will be twisted higher. Even with these two things he thinks the turbos will come up no sooner than 2000 rpm.

I like your idea of turbo for 3.3 Pathfinders. I was thinking the same thing. I have a friend that is owner of a shop that specializes in Z cars. He also mentioned a Supercharged engine. Will be keeping in touch. Please do the same.
