Garrett T3/TO4R
has anyone have or had any experience with Garrett T3/TO4R turbo? turbo specs are T3/TO4R "The Big Kahuna" compressor: TO4R .70 a/r 66.5mm inducer flow: 75 lbs/min 960cfm 360* thrust bearing standard turbine: T3 your choice of .63a/r or .82a/r housing your choice of stg3 or stg5 turbine wheel I tried to do sum research on it and it came up short. I am looking to buying this turbo to use on my B20 vtec wit a b16 head.
motor specs are
stock b20 with b16 head
1200cc RC injectors
3' exhaust
29x11x3 intercooler
2.5 piping
I am gonna be using it as a daily driver and drag car my goal is low 11s high 10s.
could anyone tell me if this turbo would drop off at 7k and when it starts making boost?

I hope you're saving a little money because that B20 is not going to last. The sleeves are known to be weak even around 300whp...pushing it harder is not a good idea IMO

do it man, people get 300whp out of b20's alot without problems, yes the sleeves are thinner, does detonation care? No whether thick or thin it can wipe them out. Like you already know tuning is going to be your best friend or worst enemy.

that turbo is a light switch. but fun. you ouly get one hiccup then bang. the b20's are probably the weakest blocks.
last years (06) b16. first time tuning anything over 1200's. 3 year old motor 84mm b16. t3t67ho. went 10.72 @ 129 27 psi on 24.5 x 15 slicks.
this years setup. still shaking bugs out of it, but so far has trapped 140.
83mm gsr same turbo 34 psi.

I noticed on the dyno the turbo makes power at 5k and good till 7 which is redline for the stock b20 is it possible to get a lower spool time on the turbo?

No. that's what happens when we have small displacement (under 3 litres). You want the top end power, you will sacrifice response because of the exhaust energy requirements that the turbo needs doesn't occur until late in the powerband.

Re: (TheShodan)
my purpose is daily driver and drag I wanna hit the 300whp on the stock block and plus(building a b20 bottomend on the side) when the built block goes in. I want the turbo to kick in at 45k and run me to 7 on stock and built prob 8 or 9k.
but my main focus is the turbo on the stock block for now without having to upgrade when I put in the built block. I want the power from mid to high and a strong powerband.

If 7k is your redline, its mostly for daily driving, and still want 10's...
Before you spend $900+ for resleeving your cylinders, you'll want nothing more than a 50trim t3/t04e, maybe a 57trim because its easier to find. The 57trim will have the spool characteristics you want, and still make 300+ on mild boost (10-12psi), depending on your setup.
IMO you'd be best sticking to a 57trim. They can make 400whp on pump gas, almost 500whp with race gas & a built motor, which is more than enough for a 10sec pass if your slicks/suspension are good.
But as long as you run the stock B20 sleeves/block, basicly anything bigger than a straight-T3 could crack your sleeves. I've seen 300whp with an 'unknown' T3 and a B18B with an intake manifold. What you HAVE to understand is the B20 sleeves are not only thin, but use a WEAKER monosleeve design. They are KNOWN to crack with not so high compression or boost.
