Rebuilt M90 Snout


6 reviews

This variant is currently out of stock

This is a stock M90 snout that has been rebuilt to OEM specs. We take used cores, completely disassemble/clean/sandblast them, repowdercoat, and reassemble with new bearings and a seal. 

How to order your rebuilt snout:

Model: This determines what generation supercharger you need the snout for. Gen3 is what comes on the '97-03 Grand Prix GTP, 97+ Regal, '04+ Impala/Monte SS, '97+ Bonneville SSEi, '96+ Park Ave Ultra/Riviera. The Gen5 only comes on the '04-07 supercharged Grand Prix models.

Core Charge: This is a refundable core charge. This allows us to ship you a core first so you can swap it with the one on your car and then return your used one for the core charge amount. We offer an extra 10% back if you want it as an in store credit instead of refunding it the way it was paid.

Pulley or hub installed: If you would like a press on pulley or modular pulley system installed on the snout we will do so free of charge. Just add the corresponding item to your cart and make sure to notate that you want the pulley/hub installed upon checkout. 

Snout machining: No longer available. This is for people that are running very small supercharger pulleys. For example if you are running our Modular Pulley System and you have enough mods to run a pulley smaller than a 2.8", then you will need to have the snout machined to clear the 2.7" or smaller pulley.

These are the rest of the items you would need to complete this snout swap:

NoteA bad snout seal will cause supercharger oil to leak out from the end of the housing and then gets on the pulley, it then flings it all over your engine bay. 

Bad snout bearings make a buzzing noise that increases with engine RPM and will get louder and louder until the SC comes apart.

A worn coupler will cause a rattling noise only at idle that will go away if you rev it. 

A bad rotor pack also makes a rattling noise like in this video. Click here to hear Rotor Rattle

Premium Quality

I’ve been buying from ZZP for years. I recently had my M90 supercharger rebuilt and the attention to detail is great, it looks great, it’s clean, and I as part of the order, I got a new pulley put on. The pulley looks really nice and is high quality, their service, communication, and speed are quality as well.

Good product

Great snout, I would recommend purchasing a zzp coupler and coupler swap kit with this as well, I did not and my supercharger leaked a small amount of fluid that ruined my #2 fuel injector O-ring, the silicone will seal the snout and prevent leakage as well as it isn't a bad idea to go ahead and replace the coupler since the snout is already off, and the syringe always comes in handy when changing supercharger fluid
