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?

 

wanna sell it? you'll never max that thing out and you gotta find a motor big enough to spool it. nice find

 

That is the most badass thing in the world. I want it sooo bad. Please sell me that.... ....TIGER BLANKET!!!!

oh and the turbo is cool too.

 

anyone else have any input?

 

I might trade for a smaller turbo like a 76mm-80mm, i like ball bearing turbos. local trade prefered

 

also could i just change out the turbine wheel and housing to make it smaller so i can run it on my car?

 

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.

 

with the quick spool valve you need an open housing not divided. just an fyi

 

thats a big bitch

 

You said it backwards.

 

oops i misread the description: "YOU MUST HAVE A NON DIVIDED MANIFOLD! If you have a divided manifold we offer the amazing quality Virtual Works manifolds to suit your needs." quoted from the store that sells them... my mistake.

 

my motto is,,, if you cant lift em, you dont do em...

Unfortunatly i am really strong hahah J/p sorry i had to

 

lol what?

 

lol what? lift what?

 

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.

 

I didn't think my motor would spool at 3500.

 

here's the tag

 

bumppp

 

I've been looking and comparing my turbo to pictures of other turbos using the beer can comparison and an s480 look close and so do others.

 

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.
