A 350(tpi) is in my 1989 GTA. The engine feels like its going to go dead anytime soon. So i was thinking about taking the tpi motor out and putting a new carbed sb chev. 350 with a weiand blower on top. I know that i will have to change alot of stuff and take out stuff, but please tell me if i have most of it. Change the in-tank fuel pump to a mechanical pump,take out computer controls, take out electrically operated fans on radiator, no air conditioning,and all other miscellaneous things. Could i use the stock radiator, stock motor mounts, the 700r4 transmission which is 4-speed auto with overdrive, stock rear differential, and in other things you think should be named. The engine that would be replacing the stock motor would be a small block chev. 350 with edelbrock RPM heads, weiand blower, and probably some type of other cam. Do you guys think that i will run into any other problems and do you have any ideas.

How good are you at setting up blowers?

Why??

Why not use some other kind of blower, and leave all that alone?

There's no reason that putting in a "new" 350 requires doing away with that stuff.

A carbuerated engine doesnt work with my intank pump, it doesnt run off a computer, it doesnt need the electrical operated fans as the engine has its own fan, and a/c would be a hassel to hook up. Why would i leave all that in there and have alot of clutter with things that dont work(computer, fans, a/c, etc.) And i didnt specify on what blower i was going to use so i dont know what you mean by using a different kind?

You don't have that. You have TPI. what's all this carb talk about?

Does the car run? Then the computer is fine. Leave your elcetric fan alone, it's fine. Don't hack your AC off, that devalues the car. Improve the car instead of just hacking senselessly on it.Yes you did.Last I knew, all they offered was suck-through Roots blowers; but I could be wrong.

There are several brands of centrifugal blowers that are specifically designed for your motor. Basically a bolt-on kit. That's what you need.

Check the "Power Adder" forum on this site.

I was talking about taking my TPI system out and my old engine and replacing it with a carbuerated engine, in that not needing any of computer controls if iam going to put in a carbed engine. Let me say this again, Iam going to take out the old engine with the Tpi set up then i wont need the computer because a carbed engine doesnt need a computer. I didn't specify which weiand blower i was going to use(8-71, 144, 142, 6-71, etc.) Iam sorry for this misunderstandment and i hope this thread will go back to the original post.

why not keep the electric fans? Are you planning on running a clutch fan instead? Thats kind of backtracking isnt it?


"Could i use the stock radiator, stock motor mounts, the 700r4 transmission which is 4-speed auto with overdrive, stock rear differential"

In short yes.

Why do you want toStart there. I think where the disconnect is, is that you're somehow convinced that you can't change the motor and/or put a blower on it without going to a carb. That's not true.

The 6-71 and 8-71 are the Detroit Diesel blowers for either the 6-cyl or 8-cyl 2-stroke diesel engines they use in buses and such. They are not "made by" Weiand, although Weiand might sell a package including one of them. They are HUGE. Look at John Force's motor, that's a Detroit Diesel 8-71 blower (not stock, straight off of a bus, of course...). A 6-71 is JUST LIKE THAT except not as long, and will support virtually ANY small block up to 1500 HP or so. The 142 and 144 are Weiand's little "street" blowers; they look JUST LIKE the 6-71 or 8-71, as far as their design, except they're MUCH smaller. They go below the carb and extend the full length of the motor, and suck air through the carb. When you say "Weiand blower", it's not necessary to tell which one in order to know how it goes on, because it only means ONE kind of thing, regardless of which specific part # you end up with.

There are other kinds of blowers, that mount in a different way; and blow air into the throttle body of a FI system (or into a carb, but that's MUCH harder to put into effect). Lots of people use them. They're even available in CARB legal form for use in California. You can "put a blower on it" for A FRACTION of the cost of hacking up your car like you're talking about.

You're asking if you can re-use you stock transmission, rear end, motor mounts, radiator, and so forth. The answer is yes. Nothing about a blower is incompatible with any of those things. But also, you can re-use ALOT more of what you've already got, if you also re-use your stock induction system, and choose some other kind of blower.

"There are other kinds of blowers, that mount in a different way; and blow air into the throttle body of a FI system"(i think you were trying to say supercharger) Anyways i have discontinued my old idea as it's way too expensive and iam not going to drag this car every chance i get. And the gas mileage would be horrible. I fixed the engine in my car today and got it running great. I think it would be more cost efficient and power worthy to just modify my TPI system and make some good power numbers. Sorry for our misunderstandment Sofakingdom and i hope we can get along better than we have.

Right; supercharger = blower = same thing.

You're exactly right also about the gas mileage and all that with a carb and a suck-through type of blower. What you had been proposing, is pretty much in the realm of all-out racing. Not a street setup, ESPECIALLY not a daily driver, at all. Although, the smallest of the Weiand blowers, with a super mild tune, isn't so terribly bad about that. But it would probably still use at least twice as much gas as what you've got now, maybe 3 times; and be a constant headache.

What turned out to be the matter with your existing setup?

Incidentally, I don't see a problem with "getting along"; I think we get along just fine. From my point of view, anyway.

It turned out to be just a fuel filter and spark plug wires. I started another thread proposing my problem and they helped me figure it out. It was weird because this had happened before but it didnt act the same way it did last time. Because my car has a shift kit it meant that since i fixed this problem it chirped the tires going from 1st to 2nd and put a big smile on my face as it was shaking and sputtering before i fixed it. It made me feel stupid that it was something so simple but also it was a blessing that it was something so easy to fix.

Hey sofakingdom what kind of car do you have?
