i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

i'm not too clear on what exactly i need and need to do with TT'ing my CARBed 350 V8.

heres what i think i need and need to do:
-get a boost carb
-get a carb encloser(or make one. since there ALOT of $$$)
-make manifolds
-get 2 turbo's
-oil lines
-piping and couplings
-FMIC

the things i'm getting hung up on are:

-what kind of turbo's should i use?

-how am i going to actuate the wastegates? (i'm thinking of making 'em mechanical. i.e having cables attached to 'em, then to my throttle. so when i step on my gas pedal. i'll be using the wastegates!?!)

-how would i control the boost levels? (would the above ^ thinking take care of that?)


thats all i can think of right now sinces it's about 6am. i'm sure i left out things.

thanks

there is an article in the Turbo Project section that a guy turbo'd his 5.0 mustang. I think he used 2 m10 turbos

Wastegates have a spring in them and let extra gas out when the turbos make enuff pressure to force the spring open. Get a 5 psi wg.

Ur mechanical idea is the most ghetto thing i have ever heard of. Get a manual boost controller or get the Turbo XS dual stage boost controller for around 200 new

wastegates allready are mechanical. They have a spring and a diaphram. lets say you have a 9 pound spring in the waste gate. then it takes 9 pounds of boost to push down the waste gate then it opens to allot pre turbo exaust gas to come out so your turbo is regulated to 9 pounds of boost..... your planing on running boost into a carb? you have to do a draw through method. just like superchargers do. the carb goes pre air compressor and you make a box that goes on the intake plenum so you can hook your charge pipe up to it.

yeah the 5.0 TT project is for a fuel injection setup. what i mean "what kind of turbo's should i use" is: the're diffirent kind of internals. i.e ball bearings, some are oil and water cooled, etc...

i have no vacuum on my S-10 besides the brake booster. to my understanding wastegates need vacuum. right? so i can't hook that part up!! how would i be able to bypass that part of the wastegate?

yes i'm planning on boosting into a carb. but since my V8 isn't fuel injected. i need to buy or make a "complete" carb encloser. meaning that the carb is fully enclosed and all that is out of the encloser is the fuel lines and throttle cable. but i will also need a "boost carb" that is designed for turbo.

thanks

how could you have no vacuum... lol

get some T3 turbos with internal wastegates, you hook up a vacuum line to the wastegate acuators, pressure makes them open.

the carb incloser is stupid, modified your carb or buy one that is modified to accept boost. and you put a bonnet on it. you dont enclose the entire thing

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

so where do you guys get vacuum when your intake is pressurized due to the turbo forcing the air into it?

Re: i need help with TT'ing my *CARBed* 350 V8 in my S-10.
 

The wastegates need to see vacum and pressure from the manifold or charge piping.I have been helping a friend of mine with his turbo Nova project.He is using a MSD boost timing master to pull timing under boost and will be getting a turbo ready Holley from the carb shop I believe they are called.You can do twins or just run a large single like my friend will be as you then just have one downpipe and charge pipe to build.A good resource for turbo small blocks is http://www.turbomustangs.com/smf/ they have a section on sbc as well.

the wastegates dont run on vacuum, when they see boost pressure is when they move.

when you're not in boost you will still have vacuum
