20g compressor housing/ 16 centersection

[blue92laser]

Hey all, I was wondering if I took my good 16g center section that still has the exhaust wheel, the tdo5 wheel, and I was wondering if i could slap on the 20g compressor wheel to the oteher side of the 16g center-section, and would the compressor cover work for that we have for the 16g, or even better yet can we slap on the 20g compressor housing


the breakdown....

bad 20g turbo, shaft play and all

good 16g centersection with no miles but bad compresor wheel

will it work? combinging the 2?

thanks everyone

Yes it will work I did the same thing about two years ago.
It will work fine from what i remember I had extremely great low to mid range power but I didnt have much top end. Was a great street/autocross set up I thought.

A tdo5h 20g is a great street turbo, IMHO. Great flow up top and quick spool up on acount of the turbine wheel. Are you going to use a 7cm^2 turbine housing? you should. A true 16g has them.

However, you must get the turbo balanced once you get it together. It will fail alot sooner than you think. Each wheel may be already balanced. But, the wheels have to be balanced with respect to each other; the whole assembly. Bullseye and FP do this for a nominal fee: 40 bones or so plus shipping. So facter in that cost. Oh, and you'll need to use the 20g compressor housing, backplate, and perhaps some other stuff in there.

The important question is, which 16g wheel do you have - small or big? If it's big, then the 20g wheel will drop right in, since they share the same exducer size. If it's a small 16g, then you'd have to have the cartridge machined to accept the larger wheel.

As for the comp. housing, the 20g housing will swap right on and will flow alot better than if you had the 16g housing machined to fit the 20g wheel.

I completely forgot about that!
The difference between the two wheels is similar to the difference between the 14B and the Small 16G below in the top picture, correct?

Not quite... The 14b wheel is flat on the back. All of the "G" wheels have the tapered back, that's not the issue. I'm simply talking about the outer diameter of the wheel. The small 16g is 2.36", whereas the big 16g, 18g, and 20g are all 2.68", meaning any of them will interchange as long as the compressor housing is machined to fit. Don't forget that you'll need to have the assembly balanced, too.
