T3 garret turbo - anyone running it ?
I know its not the biggest turbo ever, just curious if anyone is running one, and/if they make enough boost to make it worth our time...
any details would be appreciated by the curious hlh - thansk in advance

i am looking into putting a T3 on right now, and i am not going to buy that kit... custom fab. i like t3's a lot, but if it isnt big enough
i just need to know for sure one way or the other

You are not descriptive enough. The T3 comes stock on some Z31 300zs(which are 3.0 liters) But they run only about 4-8 psi. So for low boost applications, it would be fine. But they get inefficent for higher boost(maybe 12psi+).

Put it this way, A T3 felt pretty damned good to me(for the short time I was running one on my VE 
)
But considering Nigel's experiences, maybe a T3T4 would be a better choice. I went for a T3 for two reasons, cost and my 140,000 motor probably won't like what a T3/T4 is capable of.

Don't the 300z's run sequential turbos or something? Don't know what it means actually, but to me it sounds like a small turbo for low-end and a bigger turbo for top-end. Once the small one starts to drop off the big boy kicks in. T3T4 is sosmething like this right?

Umm, to put it as lightly as I can, every one of your statements are pretty much not correct.

The T3 is used in the Z31 which is not the TT Z its the previous model.
The T3/T4 is a T4 housing with a T3 turbine.

It is my understanding that the smaller the turbo the faster it will boost. Small turbo's will spool up really fast on our cars and give great punch around town, but will run out of breath in the higher power bands. The bigger turbo will allow more PSI but will take longer to spool. Ain't I right Jeffy?
Harold, who do you have in mind to make a custom turbo for you? Hell maybe we can bug Chaz enough to build you then me a kit for dirt cheap.

Doesn't the VQ30DET run a T3? I'm just going off stuff I've read in the past 48 hours, so I could be wrong. 6-7psi of boost if I remember correctly as well. Personally I'd want to go bigger but I still wouldn't be complaining with one

For off the line quick response, The T3/T4 is probably the turbo of choice. I wouldn't say the T3 is too small, providing you are running less than 5-6 psi.
In looking at my dyno graphs, my power drops off rapidly after 5200 rpm. This is a characteristic of our intakes\ runners on the 4th gens. A T3/T4 would be a good choice to produce power over a broader rpm range - starting earlier. You do lose top end power, but you lose it anyway because of the intake runners ... how much worse for T3? .. I don't know. I am hoping to get a VI in the not-too-distant future and get that top end back! I would love for someone to try the T3/T4 with the kit to show performance differences. too bad I don't have the money to buy another turbo to try this. Actually lag is not bad at all for the T4 if you drop the clutch at a higher rpm 2500 to 3000 rpm. I really can't complain too much about the T4. Too much response at the low end just causes you to spin the wheels and not go anywhere. I can spin with the T4, might be a problem with the T3/T4.
As for sequential turbos, Supras and RX-7s are the more popular cars. The rest are just regular twins. Maybe next year, I will look into sequentials as a project. It's actually a pretty simple concept really. Boost control would be a little tricky though.

T3 is 200+ (ebay) or 700new... then you need an intercooler, plus you have to have vortech or other brand fmu/fpr... you need a shop to custom fab the flanges off your exhaust manifolds and custom bend it all around to get it up front ($$$), and then get the exhaust back out is a pain too b/c of size restrictions down there - plus all the intercooler piping. Then with a T3 you need both oil in and out and water in and out, so you must tap the oil supply both directions (harder then you would guess) and the water is easy off the heater cooler.
Then your going to want a bunch more stuff, including larger turbo - (guages, boost control maybe, pump, etc...
)the biggest $ is probably going to be labor/piping ... its nuts , but i cant give an estimate.
oh yeah, and shops hate this idea for some reason (besides performance car shops, and still 1/2 of them hate it)
