The sneeky pete is a 25 shot and I've heard a few with it say it's pretty awesome. I'm think'in about it but I have my mind pretty much set on a zex 75 shot.

 

If you really want to put N2O in your car, it is better to get something that is adjustable. The sneak-a-peak is fine, but 25 hp isn't going to make you happy when someone with a 75 shot asks for trouble, even a heavily modded NA will upset you. If you are pretty handy with the tools, a nitrousoxide system multi port can be affordable and very upgradeable, even the plate thing will be great, just no controller features (which can be added at a later date). Zex, NOS, have their little things, but the key is that they're upgradeable and 50hp shot is alot faster than 25..... HTH
