Hybrid Turbo, Homemade

[fergulus]

I just recently bought my 96 talon from my brother, who knew a guy that rebuilt parts. He made a hybrid turbo, and according to my brother's profile on here, it is a 16g/46t. I can find information on the 16G, but nothing on a 46t. When it was installed several years ago, I remember them saying it was the equivelant or better than a big 16G. Has anyone heard about such a hybrid? Like I said, I am new to this area, and do not have experience of knowing the feel or characteristics of different turbos.

over the years there have been a ton of hybrids, some good, many not so good. Do you have a picture of it so we can take a look? Wheel measurements? Housings?

I'm getting ready to replace my head gasket, so I'll be sure to take some pictures while im down there. I know that the silver intake side is the big 16G for sure. I am pretty sure that they swapped out the turbine wheels to fill up the space a little more. As far as wheel measurements, I'm not sure I want to take the turbo apart, but I can definately get detailed pictures of the housings.

I know this side view isnt very helpful, but here is a picture of the turbo with the intake off.

Not sure if this helps or not but the # stamped on the compressor cover suggests this turbo started life as a small 16g

Sounds like a 46-trim Garrett compressor was installed into the Small 16G compressor housing, mated to the TD05H turbine.

It's essentially a Frank Level 1 20G built beneath a TD05H compressor cover instead of the 20G's TD06 cover....great for a stock-appearing class or if you want to fool your competition in some friendly local racing.

The 46-trim compressor isn't well known, and it has an ENORMOUS backplate in comparison to a 20G compressor wheel. The small amount of airflow you gain over a 20G wheel wouldn't offset the added lag given by the huge backplate. You probably would've been better off with a 20G wheel.

Thanks alot for all the information. All I ever remembered them mentioning when my brother installed the turbo was to tell everyone else it was a small 16G. This helps out alot, as far as knowing more about the capabilities of the turbo. It also explains why the turbo takes quite a bit of time to spool up to the designated PSI except under WOT conditions.
