A much smaller and faster spooling t25 will make the car much more spirited for daily driving with the modest hp you are looking for.
Dont confuse him damit the t3 s60 will be just fine. Sure he can spen more on a BB 2554 but he wants to do this cheap and effective. the T3 is by no means a big turbo. But it will flow as well or better than the Greddy unit.

What spool times will I be seeing wtih the T3 S60? Will it still spool quickly? Also, Braineack says the turbo will not mate with the downpipe, so i will PM wideopen for an estimate on the two parts.

you should spool by 2300 atleast 2500 rpm similiar to the greddy guys.

Okay I sent an email to BEGi (do they reply to emails) about the T3 Outlet on the downpipes. I'll be waiting on a reply for my decision, likewise, i sent kelly a PM regarding the ATP parts Braineack posted.

the turbo you linked to him was not a T3...it was a T3/T4, probably wouldn't spool till 4000-5000rpms.


FWIW I hit 12psi by 4k, that's with a cat and 2.25" exhaust. on the BEGi manifold and 2.5-2.75" DP.

I see boost pretty much all the time, I'm hitting boost just taking corners at stop signs. by 2.5-3K I'm at 5-6psi.

Okay, so I will look for a T3 s60 NOT a t3/T4 while I wait for Kelly to get back to me, thank you for explaining the difference


The wastegate you linked to has a 5 bolt exit correct? What if BEGi doesn't support the 5 bolt?

yeah the t3/t4 is a t3 turbine, with a t40b (i believe) compressor. So it has the advantage of a smaller turbine to spool, but the compressor is made to pump out massive air, so it takes a while for it to spool, but once it does...hold on. if you are looking for a 200-250rwhp, then there no need for a t3/t4. I'm making 200rwhp at about 11psi, if I went with engine management and a better exhaust, i'd expect about 230rwhp at the same boost level.

Oh okay, so simply put, I will be having a near setup to your own. The Wastegate you linked to make the 5 bolt discharge of the T3 turbo into a 3 bolt discharge, what will happen if BEGi does not sell a 3 bolt? Thank you.

Using larger injectors, AFPR from BEGi and a new fuel pump are my goals of ~200 BWHP within reach?

Cheap? I agree.
Effective? I don't
At no point did I read of anyone asking him what his primary purpose was for building the car. If he is wanting a car that produces all of its power on the top and all he is going to be doing is drag racing, then fine.
If he is wanting to enjoy the added power at moderate speeds and rpm levels then I believe you are steering him to too big a turbo.

Magnamx, there is no doubt from reading your post, that you are very knowledgeable about these cars, but I do feel that, unless he is drag racing, he needs a faster spooling turbo for a street driven car. Otherwise he is going to have to constantly downshift the car to get the necessary rpms to spool the bigger turbo.
After all, he is only wanting 200 hp, the hybrids will easily support more than twice that! even with a small .43 a/r hotside.

True but plenty of people on here run these turbos as DD's with no real lag issues. It seems you know quite abit about garret turbos, but are scared of lag or had experience with a setup that was sized all wrong for the application. boost by 2K rpm is hardly laggy in my book and it gets progressivly stronger as the pressure and flow builds mimicing the characteristics of the stock motor. This will save on drivetrain parts and gas milelage. in my book. but to each there own.

it's the feed dude.
to me the compressor wheel doesn't actually look like a genuine garrett, but a knockoff. garrett t3 wheels are curved.

this is my current wheel:

Genuine Super 60 Wheel

This is a 50 trim:

this was an old one of mine

Ebay "genuine" T3 wheel:

since when is the drain only 1/8" NPT

the two holes are for inlet adapters (my turbo):




the drain looks like this:




remember is a CHRA, Center Housing Rotating Assembly, or something like that.

If anything I know T3s, infact it's the only turbo I know anything about.
