I have a stock 92 with that huge 21cm housing on there and Jannetty Racing has a 16cm housing for 175. 00, is this worth the money on changing it out? This factory turbo seems like it takes FOREVER to spool up, and with the price of diesel going up I dont believe I want to change the turbo altogether, but rather looking for some inexpensive things to do to help it, and this is cheaper than an aftermarket turbo, someone please let me know, thanks
