I went with a gen 5 blower, which you will notice has space for the nozzle, while the gen 3 doesn't. if you want to use methanol on a gen 3, just go with a throttle body spacer or something like that. I also recommend doing the 50/50 blend to gain the full benefit of each component ( water and methanol). I had the most success with the biggest nozzle, but if your car bogs down, you will need to run a smaller nozzle. 1000 cc's is what I ran.
I just took a look and it seems like i have space where scotty put his.
