Can I get this death turbo to spool? Gigantic Turbo! Johnny like skinny girls but never turns down a Fattie 
ok. so I just picked this up in a trade.
Its a Garrett brand new rebuild. I did research and found out: in the T18A90 family, its a/r .96 on compressor and 1.32 a/r turbine. i measured and just eyeballed rough numbers since I dont have a caliper right now.
major---
4.75in compressor 120mm
5in turbine 126mm
minor----what matters
3.75 cold=95mm
4in hot= 101mm
so 63 trim for compressor and trim = 64 turbine
would this even spool on a 346ci? can a map be generated based on this info? how big of a motor would I need hypothetically to run this on the street (i.e. full spool by 3500rpm)?
anyone have any thoughts about this thing?

Looks similar to one I had awhile back, the large exhaust side will be hard to spool at 3500, if you had a large cube motor 400+ you could do alot better with it. See if you can get a divided housing for it and quick spool valve like Zombie uses, that might help if your really set on using this turbo.

uhhh the title of your thread....never turn down a fattie....
91mm...compressor & 106mm turbine.= big motor...500cid might do it by 3500.
Your looking at a 70 to 76HPS to do it by 3500 on a 346.

my TC76 spools at 3000 ish on my 370. that thing on a 346. that will be a narrow powerband. use lots of nitrous and save for a 408. just sell it and go with a 76. who knows though maybe your car will be a freak. S480s are huge and a big PITA to spool especially on a 346. you should probably do more research though. if you have an auto you may have better chances.
