Adding Horse Power

Asked by Oct 02, 2007 at 01:04 AM about the 1990 Chevrolet Suburban

Question type: Car Customization

How can i add alot more horsepower without taking the motor out.  What super chargers work with the TBI?   Is there better injectors or throttle bodies that i can bolt on?  I have redone the entire exhaust with 3 inch pipe and a flow master super 40 so that end of things is moving air fine.  How can i add some quick hp that i will notice?

I would recommend Procharger. But they might recommend a cam swap. http://www.procharger.com/ Sounds like you have the flow in and out. But you might also look at a cylinder head upgrade.
