16g is on its way out

[1badpurple]

Ok guys my 16g is worn out. It has some pretty bad cracks all the way up the turbine inlet. Plus I think it hated 26psi for dd. What are some affordable options as far as turbos go. Im not too worried about lag, I have a PTE billet converter. Is the hx40 my best option?

do you have a small 16g or big now

 

[1badpurple]

Big 16g.

No, 16g hybrid. 16g turbine wheel and 18g compressor wheel.

Are you looking to upgrade other things if necessary or just replace the 16g while keeping your current mods?

 

[1badpurple]

My engine is built. Transmission is built. The turbo and intake manifold are about the only major mods left. I already put down decent times at the strip as well as some good dyno numbers. Problem is the turbo I have now is quite worn out(high boost). So I definitely need to make some more horsepower. High 11's is great and all, but it gets old after a while.

Get a 20g or evo 3 16g

The evo 3 is a major downgrade from what i already have. 20g is a decent turbo, but i have a converter that i can run up to 6500rpms. So basically my setup is laggy turbo friendly.

HX35 or HX40 are both good options. Alot of people I know get compressor surge when trying to boost over 20ish psi on thouse though.

Well im trying for some 10's without using meth. So far though my turbo just doesnt have enough i guess you would say uumph in it. My best et so far is a 11.82@118.

What you have is a TD05H 18G; not necessarily a hybrid, although it did begin life as a 16G.

The evo 3 is a major downgrade from what i already have.

Not exactly, depending on what your target boost level is.

The 18G compressor has a slightly larger inducer than the Evo III, but the Evo III has a lighter compressor wheel with thinner blades as well as a smaller "hub" area to the wheel, so the blades are deeper and grab more air.

Notice the difference in compressor wheel design as well as the blade length between the 18G (first) to the Evo III 16G (second):

Some have logged 42lb/min with an Evo III 16G, and that's the same peak number as your 18G. The Evo III 16G will also spool slightly quicker than the 18G.


In your situation, I would buy a FP HTA68. You're already set up for a 16G platform, so it will be a direct swap. Going to something as large as a 35R or HX40 will take a lot of getting used to if you drive the car daily. You'll almost never be in boost unless you drive the car like an animal.

I know they are similar. The problem is neither are capable of flowing enough without the air temps getting way to hot.

As far as the compressor surge goes, is that on auto cars or stick cars?

Well I actually plan on buying a Audi for a dd this week. So lag isnt a issue for me. Arent the dsm flanged turbos not capable as flowing as much as a t3? i have a topmount manifold already sitting thats t3 flanged. jusmx you dont have any hx turbos right now do you. Just for fun ill include a pic of my dirty bay.
