stock rebuilt motor,302 bored to 306, what do i need to change. motor wise, to put in a twin turbo setup of about 6- 10 psi ?

[usmcsawgunner]

i dont know much about turbos but wats the point of having TWIN turbos for only 6-10 psi? twin turbos are for like 20 psi and stuff.....anyway i was looking at a supercharger with 6-9 psi and they said there really isnt very many upgrades you need to do..maybe buy a leadfoot weight-reduction kit.....

[El_Cangri]

twin turbos arent needed unless u want to be different from other people.... There are 2 twin T setups one is a little turbo for the low rps and a big one for the high rpms this is a good setp but with the big motor this one is not needed.... the other one is 2 big or w/e sized turbo working at the same time and activated at the same rps this is the best TT setup but u dont need any 2 tt setup cause if u findg one great Tt with the current technology in Tt u dont need 2 only one is needed now thats why race cars have only one oh well at least 99% have one t instead of 2.... cricket has more knowlege in turbos send him a p.m

What race cars are you refering too? I would think weight, space, and sponsers with cash that can afford highly refined custom setups are the deciding factors of why there is only one.

[El_Cangri]

there r a lot of factor but I was reffering to that the race cars have very powerful motors and 2 t's arent needed cause the car is powerful enougth and 2 t's would not do anything 1 is enougth that was my point sorry if i didnt wrote it b4 I dont know how to explain it exactly..... hope u get what i mean

[93GT]

well i was planning on keeping the stock bottom end, swapping the head gaskets with some metal ones and maybe boring out the heads. i dont want to do what everyone else dose, i have only seen prochargers and single turbos.

[BoostedMKIV]

Yeah, for your car, a supercharger would probably be the most beneficial.
Then you can get nice low end instead of waiting for boost.

Twins are great when they are sequential (as mentioned above, the small and large) because the car is constantly boosting, from low rpms to high rpms.
Parallel twins are a lot like one big single, where theres a good bit of lag but then it kicks ur ass when it does hit boost.

[93GT]

maybe a couple of turbos from a cummins diesel, they boost at low rpms?

Not much. Boost sensitive FPR, and some larger injectors and a fuel pump. Should be good for 400whp.

Twin cummins will NOT boost at low rpm's with a 306 pushing them! First off figure out your power plan. Where do you want to make power, how are you going to use your ride? How are you going to get your new found power to stick to the ground?

To be different for a reason is good, But remember most people do things for a reason! So maybe you want to follow proven combo's! Otherwise you could end up with a great shopping list but a car that sucks!

My advice is to figure out your powerplan and go from there. If your into turbo's check out hellion power systems and John Urist.

i was planning on keeping the block the way it is maybe porting the heads and swapping out the head gaskets, i want to have a simi race car,so to speak, i have a nother vehicle that im going to drive around the mustang is going to be for the track.

WHAT?? who runs it like that any more?? everyone is using sequential setups, its harder to tune if its like that, if you have rebuilt block with forged internals then it should be good to push 12psi through that block and rate you at about 500hp easily

it is almost WORTHLESS to run 2 cummins because it would problably never spool if your running 2 of them, it is recommended to use one big turbo instead of running 2 big turbos because it would take forevever or never spool up with 2, go over to TurboMustangs.com and do some reading, my user name over there is TurboStang140

[93GT]

so turbo lx what kind of turbos would be quick to spool and be in a junkyard.?

[TurboLX]

well it depends on what is avalible to you

[89LX347]

why do you want 2 turbos so badly? and why dont you go with a SC i mean the 306 will do great with both but why a turbo..and go with cometic head gaskets..they are expensive but worth it

[neverfastenough]

Turbos kick butt. Whose butt? Anybody that has a N/A car or a supercharged car! Every day. If you got the dough and the room get the twins, but even a single will kick a vortech's butt. Turbos are non parasitic, meaning they don't rob hp form the engine via a belt. Therefore, the same psi turbo puts out more hp than the same psi supercharger.
