Thread: 99 350 "R" engine fuel induction system

Tweet

Basically an Iron head ZZ4 engine now....
What fuel injection system will deliver the best low RPM HP???
I Love the older TPI systems but I don't want to drill the heads for the older style intake....
Is there a factory fuel injection system for the Votec style heads that can deliver 350+ HP????
Sorry If this is a stupid question....I'm a factory trained EXPERT on fuel injection by GM And Chrysler... I can fix a new Viper or Corvette.... but I'm building my first car & need help!!

I do believe this is what you are looking for: http://store.summitracing.com/partde...3&autoview=sku

Here is an engine that uses the fuel injection system and it makes... 350hp. http://store.summitracing.com/partde...0&autoview=sku

I'm not sure if the system is available seperate from the engine, but GMPP has the Ram Jet system, which looks similar to the TPI. If you haven't oredered the ZZ4 yet, check out the Ram Jet 350 engine.

With you working at GM, maybe you can convince them to sell you the Ram Jet set up seperately if it normally doesn't do so.

The first link is to a seperate ram jet injection system and manifold. You will need to buy a ECM to control the injection system. GM does not supply one.
