GT15 on 450CC engine.
 

Ok before anyone hates here, unlike a lot of other people who say they want to turbo a quad/bike and then give up, I am actually going to go through with this.

Basically what I have is a Stock 07 Suzuki LTR 450. I am going to be building this turbo kit myself. I do have the skills to fabricate and tune, but I am really confused on a suitable size turbo for the build. I want to run about 6psi and was planning on going with a GT15.

Here is the turbo. I may go with a Garrett though despite my good luck with the Ebay turbos. CXRacing GT15 T15 Turbo Charger Motorcycle ATV Bike Turbocharger | eBay

Any input on how you feel this size turbo will perform would be greatly appreciated.

Thanks.

i would go with the smaller gt12 turbo. a gt15 on that engine may not spin up till high rpm.
