What kind of info do you want? I will say that you should have a steel crank, blower/turbo pistons, 4 bolt main block, and if runnig a turbo the proper size turbo so you don't have lots of turbo lag.

 

[vortec]

go with sequential turbos or twins with variable vane geometry to get rid of most of the lag.

 

[Thunder]

I dont know how much you want to spend. But if you have lots of spare ca$h laying around Banks makes plug and play bolt on twin turbo kits for most all SBC that will make 500 to 800 hp.
If you are looking to twin turbo a 350 you must have a bit of spare change in your penny jar.
You are looking at some serious cash just to build the engine to handle that kind of HP.

And I got flamed for that.

Apparently he wants to do it for under 1000 dollars or something.

$1000 ????????



All I can say Is NO WAY!!!!

Well I guess if you got some bailing wire, duct tape, and...........................

 

[sled_dog]

First step, remove 97 computer and fuel system.
Second step, start from scratch....

The Vortec single injectors system is damn near lacking in stock form. To supply a twin turbo engine you would have to come up with some major fuel system improvements. Namely larger injectors(no one makes), or a secondary injector system(seen it done once or twice). The Vortec Injectors system uses 19lbs injector pintles. Thats 8lbs less than STOCK LS1 injectors that aren't used in turbo setups.

A sub $1000 turbo setup is DOABLE(twins is questionable in my mind), but I mean on an engine that can support the setup. If it were anything but a Vortec 350, I would say go for it... You need a fuel system that can support it first and foremost.

And you should just start researching turbos. To say "give me info", is not the way to get it. Look for it. No one cares to just "give info". There are WAY too many particulars to just give you. Some guys on here could write pages on turbos, and it would just be a waste of their time in the end.

I am trying to be helpful I swear.

But if you are serious about it, you have to think about what your goals are first. Big power numbers? Minimal lag? Drag? What?

 

[ryan22re]

Maximum Boost by Corky Bell. Buy it, read it.

 

[original balzer]

LOL no not under $1000 and not super high HP numbers lets call it a factory style build IF the factory built such a thing (I know they didnt) I want to build it to near factory specs aside from lower comp and turbo grind cam. to make around 6-8 lbs of boost. the way i figure it can be done fro right close to $6000 and would make around 500-600 hp. simular to a mild performance crate engine but with more bang for the buck basicaly. I seriously think it can be done with 2 small turbos kept on the small side even for a 4 cyl car that way lag would be almost non existant. smaller turbos are cheaper because of the ricer craze. In the end i think it would be very simular to going out and buying a crate engine say a zz383 for instance. But it would make more power and get better feul economy.

I hadnt took into account for the vortec's feul managment YET but with the build I propose it shouldnt need much more than stock. I have been told that its possible to modify the injection system for around $500. I dont know the details as yet. It could also be smoke being blown up my .... anyway i just figured a thread about turbos and blowers wouldnt be a bad idea. At least even if i fail im my attemnt people will be able to read exactly why it wont work.

"MAXIMUM BOOST"was wrote in 1977 and revised sometime in the 90's i do have access to it and thats what gave me the idea. Well that and my cousin toying with his sand rails porche (sp) engine.

That Gale Banks example IIRC is approx. $25,000-$35,000 !!

Until the laws of physics are repealed, that simply won't work. It takes more fuel to make more power. Turbos add extra air, but that extra air must be mixed with extra fuel or the engine will run lean and the pistons will melt. To bump the power up by, say 50%, will require 50% more fuel.

 

[DEMON44]

Thats why diesls are way better for turbocharging..........

 

[HarryH3]

Why? You still have to add fuel by increasing the injection pressure and/or installing bigger injectors.

 

[Thunder]

I am just wondering? Why in the world do you want to go thru all the expence and hassle of twin turboing a V8 and only putting 6-8 lbs of boost to it?
You can get those numbers with a single turbo a lot easier and cheaper.

Also
All you are going to do the engine is put in a cam?
Good luck
Put 8 lbs of turbo boost to a stock Vortec engine and you will be picking up parts. Once you get over 400 HP you will need forged pistons,rods,steel crank,and have the rotating assembly balanced. Those early vortec heads will not handle the high cylinder pressures they will crack.
With the stock engine I would not want to go over 5 lbs of turbo boost.

 

[4X4HIGH]

Blowers and Turbos can do some damage really quick even with small amounts of boost if the engine isn't built to accept a Blower/Turbo. I had a friend years ago install the little 144 B&M blower on a SBC and with only 6 lbs. boost broke a steel crank in half and took out the first 3 main webbings of the block and broke 2 rods and twisted 3 others. Even with the $6000.00 budget that isn't enough money for what he wants to do.

 

[smalltruckbigcid]

Do a 10-1 big block. you can get that much power and its easier to tune install and maintain.

Only fuel is metered into a diesel engine............. not air........

 

[HarryH3]

I know that, but you still have to add fuel to make more power. And you still have to watch those EGT's so you aren't making puddles out of your pistons.

 

[DEMON44]

That all true.....but you do not have to add fuel if you don't want to....... Unlike a boosted gas engine. You see what I'm getting at.

I can still get 20MPG out of my 500 horse diesel it just depends on how I choose to drive it.
