Created a Turbo, Good or Bad??????, will this work...... Options

Ok guys, im putting the GSX back together and i dont have a stock turbo to replace my 16g that i sold. So, this is what i have done. A few months ago i got a T4 turbo off a buddy that was suppose to fit on a DSM but the header was all f'd up and the compressor housing wouldnt fit ( hit the block ) , also the ex. housing has the 5 bolt pattern and i dont have an o2 housing that will work. SO , i took my old 50 trim (the one that blew up after 6 hrs. of use) and combined the two turbos. I took the exhaust housing off the old 50 trim and put it on the new Turbo so i will be able to use my old manifold and o2 housing.

The center cartridge fits right inside the old housing and the clamps go on as if it was meant to be. The only difference is the compressor wheels are different sizes. The new center section is a little smaller and doesnt fill the hole completely. WILL THIS CAUSE AN ISSUE OR WILL IT BE OK TO USE FOR AWHILE??????????

The old turbo has AR63 on the housing and the new turbo has AR53 on it. So the wheels are just different diameter correct?

Help me out guys, so i can get the GSX back on the road....

I will update my last post with all the current info on the car in a few....

thanks
TJ

The turbo will have a lot of trouble building boost as Kicks said. The tune may be way off (rich) and might be a little slow starting because the engine will be drawing air through a slow spinning compressor side.
