Now you just need to get rid of that ancient paddlewheel - uh, I mean - stock turboI don't think the % view of how much you are going to enlarge the holes is practical because common drill bits don't come in those sizes. That's why I choose the sizes I did; I could buy the drill bits. I'll post a video of the engine running so folks can listen to the sound. My indie, my self and my neighbors all think it sounds like a 4X4 truck now- not that that is bad. The turbo whistles more than before, which I like. It's not too loud by any means. I still have to monitor how I drive so I don't give it full throttle near the 2/3 or 3/4 shifts as it flares. I don't think there is much to be done about this- just gotta live with it. The 1/2 is fine.
I'll be drilling and reaming mine soon hopefully. Although I won't be able to drive the car for another couple months (snow). My plan will be a 25% enlargement of all holes. Already starting with the "uprated" '85 prechambers with the larger injector hole and lower seat.
