I am almost out of college, and I am looking to gain a little power for my car. I have already decided i do not want a supercharger, and that a turbo would be the right choice. I am not doing to get a different car, so please do not suggest that. I have found two setups that seem good, but I still have a few questions.
1) Who makes the best turbo?
2) Do turbo's damage the engine. I have heard of 'surge' damaging engines.

Thanks.

1) best full kit is powerhouse turbo
2) they put extra stress on it, but a safely done system with all supporting mods will not take much if any life out of the car.

who makes the best Turbo is an opinion... many companies many options blah blah blah ...

garrett in my opinion makes the best turbo...

now if your looking for a turbo kit try powerhouse411.com

turbos can damage the engine if not done properly

whats the difference in a turbo and a turbo kit?

[itschristorres8]

power ftw

a turbo is just the turbine with the compressor

a turbo kit is the full kit you'll need to make it work on your car

wat would be your reason for being against s/c?

the parasitic effect it has on the engine, which robs power to make power, and it lowers the fuel economy more than a turbo does. and that a turbo set at 9psi would beat an s/c set at 9psi.

its easier to install, and i could probably do it myself in a day, but i like turbos more.

[DeMello]

i thougth that KBs can start making full power at 2000rwpm and continue till redline?

and i know the turbos get more hp per psi but whys it really matter wen you can just set the psi up...like i get a KB at 11psi and you get a turbo at 9psi and where both making the same kinda power but i saved like 4grand rite?

4grand?! yea right
you wont ever save that much from going s/c instead of turbo. maybe MAYBE $1k at best

second if you set yourself at 11psi and a turbo at 9psi the turbo will still win.
if it doesnt i can just set up the boost at 11psi then the s/c loses....you say ok 15psi and blow your motor. there are limits with boost

roots/twin-screw s/c create a lot of heat as well

there is NO way to seeing a s/c being better then a turbo
aside from the bit of cost which in turn will still not make up for the turbo vs s/c difference

look at the 99-04 v6 mustangs with s/c...look at there times vs a turbo guys time.

real situation

theres a 4.3L built motor s/c mustang at 18psi that makes 11.7 passes with say 3400 being nice


theres a turbo v6 mustang 4.3L on 14-15psi made a 11.1 pass with a slipping tranny, and 3900+race weight on his old setup...made 530rwhp s/c guy made 495rwhp

the turbo dude just pulled 595rwhp SAE on 16psi--with big 19inch rims
they're motor and tranny setups are almost IDENTICAL

s197 GT guys with KBs STRUGGLE to make 11 second passes with8-10psi...turbo s197 GT struggle to make 10 second passes...


thats 100rwhp MORE with 2psi less!

[DeMello]

oh well i thoguth you could just keep bumping up the psi on a good s/c like the KB and make just as much rwhp (youd just need more psi)

i mean with a KB i can still make 400 or 800 if i wanted too rite

[browna09]

ya well i just have a regular v6(no forged internals or anything) so i dont think i can go over 10 psi with anything

i was under the impression that turbod cars were more susceptible to heat soak than s/c'd cars...
maybe i just heard wrong, but i'm thinking about it and... well don't turbos turbines spin faster than a s/c's? doesn't the turbo run off of hot ass exhaust? maybe i'm wrong, i've never owned either a turb or a s/c. explain to me how a s/c would create more heat as opposed to a turbo.

rear mount turbos, like the sts, dont add heat to the engine compartment

STS is ftL
there kits put out less power then vortech kits...and prochargers
so actually im wrong in this case a turbo system like STS would be a worse idea then getting a s/c

turbos are definitely more efficient and make better power, but what are you looking for? a track beast or a daily driver? roots/twin screw superchargers would be a better dd application IMO because they are at full boost by 3000rpm. for daily driving they are perfect because you normally stay in the lower rpms where you would be at full boost. if you want a track beast wher eyou will be at high rpms then you would need a centrifugal s/c or a turbo. they build power in similar ways but the turbo is still more efficint and gives better power due to no parasitic loss from being belt driven.

street daily driver - roots/twin screw
track beast - turbo

i think total opposite....with a turbo u can relatively keep ur same gas mileage except when u get on it, but with teh supercharger it will lower ur gas mileage, so IMO that makes the turbo a better dd idea

+1, thats my plan, parallel twins on my 3.8

you can get turbos that are fully spooling at 2900 rpm
