My 1988 firebird has a 305 i think or a 350 doesnt really thing that effects the question im asking too much i intend to place a twin turbo ket as well as a supercharger (if possable it doesnt seem to get into each other as well) and i would really like to place a nos kit into her i am wondering if this would blow or damage the engine,
as well can anyone tell me how to tell the difference in a 305, 350? cause i have 2 different people saying my motor is 2 different sizes and both seem to know what there talking about. i will post a picture when im able to thanks for any and all information provided

Hmmmm, two turbos, a blower and nitrous. Yeah, it's possible, if you start with a budget of around $25,000.
It's fun to read magazines and sit around and wish, but you really need to come back down to Earth and find out the basics of engine building.

Yep, put the Mad Max movies away and stop looking at "World of Wheels"/ Autorama/ show car magazines. What your asking doesn't work in real life.

If you can't tell a 305 from a 350, you won't even get one of those three items to work successfully. Do some searches and learn the basics first.

lol, twin turbo kit to fit a firebird (they had them stock in some editions not sure though if they were twin) were at 1100 dollars on ebay, supercharger kit 3500 on summit racing, also will fit and should work on the 305 not sure about the 350 there though, and nos kit for 300 dollars as well what im talking about isn't that big of a project total budget for my motor would be around 5000 dollars or so, but thanks for the advise all the same. I do some research before i speak usually lol,

$5000 for the three kits but you haven't addressed the engine itself. Each of these kits will require additional $ to be functional. Then you will need more $ to make them all work with each other. No disrepect but if you can't identify a 305 from a 350 I question if you can do this without professional (more $$$) assistance. Assuming you are talking of a used 88 305/350 you are going to need machine work and internal parts to pull this off. I think this is where Techinspector came up with his $25,000 estimate.

i understand what you mean, which is why im asking about it here, and thanks for not simply flaming me, i know nos is a very bad idea in general, but a simple twin turbo shouldnt be too much extra cost to install, and simply to say i honestly im completelly new to this kind of things, which is why i joined the forum. :D can you tell me why i would need to get machined? or is that just cause of the nos?

IMO to run any of those three you will need a built engine with forged pistons if you want it to last. Doing what you are talking about would destroy a stock engine quick
so your telling me my stock engin will need to be modded to be able to handle the greater strain? even if i just use the twin turbo? so what would you recomend me do other than forged pistons?

Honestly you don't need any power adders to be dynamic.

Anytime parts are subject to power levels beyond their design capabilities bad things happen. As the miles add up stresses and wear further lower that the parts are capable of withstanding.

Stock carbureted 305.

so for the time being untill i ensure the motor parts are able handle the excess stress, what should i do to gain extra hp?

Son, it's like I advised you earlier in post #2 of this thread, learn the basics.

Start with this book....
http://www.amazon.com/How-Rebuild-Y...=sr_1_5?ie=UTF8&s=books&qid=1251335311&sr=1-5

Then read this book....
http://www.amazon.com/Build-Perform...=sr_1_8?ie=UTF8&s=books&qid=1251335311&sr=1-8

By the time you've digested what the author has said in these two books, you'll be able to begin doing your own research and digging deeper into making horsepower with turbos. For instance, your next read after gettin Vizard under your belt might be this book....
http://www.amazon.com/Maximum-Boost...=sr_1_4?ie=UTF8&s=books&qid=1251335566&sr=1-4

I'll also give you some areas of engine building to research on the web like I did another young man who was interested in learning....
"I'll give you some more homework. You'll be able to talk more intelligently about motor building if you surf the web and read information on the following subjects:
Static compression ratio
Dynamic compression ratio
Squish
Piston compression height
Block deck height
Piston deck height
NOTE: Some writers will refer to simply "deck height" when talking about piston deck height. This is erroneous and shows their ignorance in using the correct terms. Be aware of this and be careful. Block deck height is the measurement from the centline of the main bearing bore in the block to the top of the block where the heads bolt on. Piston deck height is the measurement from the crown of the piston to the top of the block where the heads bolt on with the piston at top dead center position. Block deck height is generally in the area of 9.025" and piston deck height is generally in the area of 0.025" with stock production parts.
Camshaft duration at advertised figures
Camshaft duration at 0.050" tappet lift
Camshaft tappet lift
Camshaft valve lift
Camshaft intake valve opening point
Camshaft intake valve closing point
Camshaft exhaust valve opening point
Camshaft exhaust valve closing point
Camshaft intake lobe centerline
Camshaft exhaust lobe centerline
Camshaft lobe separation angle (sometimes called lobe centerline or simply, LC)
Camshaft overlap
Rocker arm ratios and geometry
Pushrod length relative to establishing rocker geometry
Advancing the camshaft in relation to crankshaft position
Retarding the camshaft in relation the crankshaft position
Piston to valve clearance
Valve spring coil bind

There, that should keep you busy for a few minutes

Here's a pretty good tutorial from Iskenderian to get your mind started....

Also, read through this list of tech tips written by Iskenderian..

Here's an excellent tutorial written by Dimitri Elgin of Elgin Cams...

Now, my best thinking tells me that I've wasted my time posting this and that we'll never hear from you again. Prove me wrong.
