92_RS_305

I'm wantin to keep the 305 in my RS given it's a 25th anniverary edition and keep it mostly original but as everybody knows it lacks in the power department. I've come across what I think will be a pretty good setup making about 350hp NA....thinkin about adding a 100 shot of nitrous for those "just-in-case" moments. My question is what are my options on supplying this thing with air/fuel. I'm guessing the stock throttle body is not gonna be enough. Would maybe a 454 TB work for it? Anybody got an idea?

I'm using a 52mm tb with my 360hp crate engine. The engine maker suggested the 52mm was a perfect size and the 58mm would be too much. But I'm running TPI.

I never understood the TBI cars. Is it more like a carb. equipped car?

what are you planning to do to get the 305 up to 350hp?

Im alittle lost, are you getting the 350hp with the 100 shot or with the 100 shot on top of?

1987IROC, TBI cars are similar to carb'd cars just fuel injected of course. The injectors are placed over the throttle body mixing fuel and air in the intake manifold instead of the port injection with the TPI setup. The setup I was lookin at had Vortec heads, some aftermarket intake and a pretty decent cam. Not really sure on the exact numbers but the setup yielded 345hp to the rear wheels.....And the nitrous will be on top of the 350hp....

Unless you have the "heritage package" with the stripes, you have the same "25th Anniversary" badge that every other 92 Camaro came with.

The hardest part about the TBI setup is the computer. Its slow and there is very little you can change. You can replace the computer with an EBL setup, however. Then you'll need the 670cfm throttle body, and some larger injectors.

My car is one with the Heritage Edition. What is EBL? and where can I get the 670cfm throttle body and larger injectors?

Here is a TBI intake manifold. It might support 350hp.
