was wondering what problems i could encounter running a t3 on my lude, the t3 is .42 and .48.. comes with an internal wastegate, seems to be in good condition.. would it lose power at a certain rpm or something? this would be for a stock block jdm h22a.. purely street purposes @ 6-7 psi.. planning to build/upgrade to t3t4e later.. anyone have any positive or negative opinions on this please let me know specifically what problems it might cause, thank you

no comments huh.

 

If its a 2.2 or 2.3L its probably gonna be too small

Ignore this.

The boost that you are looking toward will not be anywhere near maxing out the T3. It seems that you got it used though. Does it have any shaft play? You can test for this by placing a finger on the tip of the compressor-wheel's shaft and trying to move it in any directoin. If it moves, it may be in need of a rebuild. Also, if you look into the turbine housing you may feel some dried oil. If you feel oil, the oil seals in the turbo have expired.

If means anything to you I ran this exact turbo on my b16a, I ran 7psi up till 5krpm then from there up to redline i ran 2-3psi. Boost woud drop off above 5k rpm it just couldn't flow enough for that engine.
IMO it's to small, sure if your looking for a little kick in power (40whp or so) it will work.

 

It will work alright, but I would recommend a larger turbo. Just don't expect to make alot of power. Funny, you asked this same question of SuperHonda.

Just remember not to jump on the anti-T3 Honda-Tech bandwagon. It's complete bullshit.

Well, to be honest, this just dosen't make sense. Turbos don't make less boost as your RPM's climb, and especially not at 7psi. A T3 like this is good to almost 20. On top of that, they don't "unboost" as rpm increases. They'll remain at the same pressure, but make less power because the efficiency is falling off - in which case, you were quite distant from at only 7psi. If you've had problems like this on your car, it was for unquestionably different reasons aside from the turbo. Piping leak perhaps, but definitely not the turbo. Turbos don't say "whew..this is hard work. I quit." Smaller turbos rev higher with more boost on bone stock engines.

I see what your saying but the turbo was rebuilt before i put it on (I had it rebuilt) so I know it was in good condition.
I ran it on my sohc with no problem at 10psi, swapped motors and thats when problems started. It did what I described above.
I was not the only one who had this problem, I found several other people running this turbo and a b16a...they all complaned of this same problem. I swapped wastegates (5 in all) and even went with a tial still no resolution. I finally swapped turbo's and nothing else (piping intercooler all stayed untouched)...suddenly the problem was gone. I don't know what to make out of it....
I know turbo's don't just give up, but there is a point when you exceed the flow of a given turbo...Don't know what to tell you.

 

I still don't see how something like that is possible. It defies physics.

 

yeah, i also asked this question on hpoa and po, not to mention HAN :D
ive got nothing against t3's.. just making sure its good for my application
Thanks guys

I don't know either man. ......
In my job there are things that happen (without getting techincal) that nobody can explain....There is no logical explanation so I'm rite there with you......
