Which GT55 turbo were you looking at? There are tons of options out there on GT55s so let me know and we can go from there!

The Y2k's I have on the shelf have the BILLET 88mm compressor wheel, Ball Bearing Center Cartridge, and the 101mm exducer and 108mm inducer turbine wheel with 5" discharge on either a 1.23 or 1.39 a/r

GT55 with the 88 or 91mm compressor wheel, 111mm turbine wheel

Anyone know how they compare physical size wise?

Size wise I don't have a GT55 here but it appears the compressor cover on a GT55 would be a touch larger, but not a lot.

The better question would be what are you using the turbo for and what are your goals?

I did a little digging and found these for you! Product drawing for each!

lsx 427, 1300rwhp, is what it would go on.

Do they have a turbo that can compete with the PT88 yet?

I know they have a new mid-frame in the works, I will try to get more info on it for you!

Thank you sir

Turbonetics' new mid-frame will pack an 75, 79, or 83mm Billet compressor wheel coupled with 87.6mm inducer/ 82mm exducer turbine wheel.

So far: We made over 900whp and our testers dyno couldn’t register anything more since it maxed his dyno at 1100lb/ft of tq. That was only at 22psi on an LS-motor.

In your opinion how do you think it will stack up against the PT88?

With the design of the wheels and larger housing I am a firm believer it will out perform a PT88, however it is physically larger as the Turbonetics mid-frame uses the y2K compressor cover. With this, the fit of a PT88 will be a lot better, much more compact.

I really appreciate it Richard! Thank you again and very glad you love the turbo... it is an awesome unit and should treat you very well!

So would that mean that it would not fit with your kit or that it would just be tight fit?

The Turbonetics Mid-frame with the y2K large compressor cover will not clear on the T4 kit without some mods.... it is a BIG T4 in comparison to others.

Gotcha
