Default 98 12 valve performance h1c?

Ok i have a 98 12 valve with factory hx35.. i got a h1c from work off a fire pump that needs rebuilt.. can i put a 16cm exhaust housing and bigger compressor housing and wheels and swap it for my hx35? Will it make a difference or not worth doing?

the H1c naturally ran (OEm built) at half the pressure a stock HX35 ran.

I wouldn't bother.

Ok cool thanks! I jus seen all the aftermarket stuff like the bigger exhaust housings and compressor housings so i didnt know if i could build it to be better than a stock hx35 with like a 16cm housing and a 60mm compressor housing.. i guess i will jist rebuild it and sell it since i got it for free

Well like i said it def needs rebuilt i can touch the wheels to the compressor housing by turning it by hand.. and it needs a new exhaust housing because the one thats on it doesnt look to be a standard turbo flange.. the flange is about 4"x4" and it has the two exhaust holes but also hase four smaller ports on the outsides of the flange.. like i said it came off a fire pump.. but if u wanna message me ur number or email so i can take pics and send them to you so u can see if its what you want.. but if u want it i would just say 50 bucks plus shipping so id say 60 bucks

buddy wants more air sooner. I figured if this guy is rebuilding his H1c with stuff to make more boost, then buddy could feed this one with his stock H1c.
