what kinda of power can i expect from the two? what kinda mpg would i get roughly?

 

A supercharger is more reliable. It is mechanical and gives you power quicker. The turbo spools up and gives more power but later. Turbos are more finicky.........

 

that seems to be true on many cars, except for ours as I found out

 

I had a blower for about 40,000 miles, then I couldnt handle the problems anymore so i took it off one night and sold it. 2 months later I got a turbo and It is way more worry free and consistant with performance.

 

not really the whole truth anymore.

both if done right are very reliable.
the turbo if done right (properly sized) will give boost just as soon as a supercharger.

the turbo has one advantage...you do not need to be in boost all the time. this saves some wear and tear. it saves fuel too.

either setup should get you about 135-140 to the ground.

as for MPG...my supercharger gets me 23-ish mpg.
if i take the belt off i can get 25-26mpg

my friends turbo xb, gets 27ish.

 

If the drive belts on our cars were a 6pk or wider, and the crank pulley keyed to the crankshaft instead of an 1/8th inch roll pin than I would be happy with the supercharger.
The fact is that the 1.5 in our cars is really design-flawed for supercharger application. On the otherhand... Toyota has a Turbo Vitz from factory in Japan( same motor) , and TRD has a Turbo kit in Japan, that alone should shine light on your decision.

 

and dont expect 130-140 to the ground, that's bs.
112-120 is realistic on a good dyno without jacked-up calibration. i am at 116who and 127ft pounds of torque @4.5 psi with my turbo.
last year I was at 109whp and 112 ft lbs with my blower. (these are with out N02) with a 35hp shot I was seeing 139whp along with the blower on a real dyno. That same setup read 164whp on a crappy portible dyno-jet.

 

those portables are way out of wack...

i've got mine to show 143whp on three different brands of dynos. (i used to install the dyno's for NY & NJ inspection places)
esp, spx, mustang...all showed the same range of numbers.
that was at 8psi.
now i've got it pushing 12psi.

no bs...real setups.

 

the neverending question..., sc or tc.... it really comes down to what you want out of the kit...

 

i want to see that 143whp next to me at the track. u should run mid 14's with that. Race me at the next VIP 1/8th mile shootout.

 

Which would be better if you are running NOS also?

 

Also what other upgrades to your motor from stock do you have to push 12 PSI?

 

nitrous in addition to boost on these motors, without being built, sc or tc, is asking for trouble. im running a GReddy SC on my 5spd and i love it, i havent had any problems with it at all. it was bolt on a go, havent had to fix anything under the hood yet, in fact, i havent been home the last couple months, im deployed right now, but my wife has been driving it, she hasnt complained yet, and she is a picky person. the GReddy SC on a 5 spd in addition to other basic bolt ons will get your 0-60 down to the high 6's. enough to mess with most "ricers" you might encounter... if you are wanting to push 12PSI, your gonna need rods and pistons...

 

internals, nothing.

the only other mods to make this safe was injectors, and a fuel rail. (my kit came with a new fuel pump..)

the rods from stock are strong forged type, so no need to touch them until you get close to 200hp.

i've been runnig 12psi for 3 year now...on a bone stock motor.
you need to do nothing to make this work and work well.
if you sit there and say 'you are asking for trouble if you do...' tell me who else has had any problems from the boost.

oh, thats right, you can't... you just have been told that and you trusted those who said it.

 

^^^^ dangggg

Seriously though, its Daves fault that i will be running boost in the spring of next year. I finally got to ride and drive the car and it handles just fine.

I have an automatic, so im leaning more towards the Greddy Turbo set up. Having an auto means that i wont have to wait as long for the turbo to spool up and get me to that sweet spot.

Now if someone can point me to the nearest and least expensive place to purchase the Greddy .. ill be all good.

 

'tell me who else has had any problems from the boost.

oh, thats right, you can't... you just have been told that and you trusted those who said it.' i never make assumtions, i have seen teh video of the blitz sc on the box running down the track with nitrous, he left his motor all over the surface of the track.

 

also, your running 12psi and still not close to 200hp? how far out of the efficiency range are you running your turbo?

well you only showed one idiot.
the boost was fine, it was when he added nitrous to it that casuses problems.

seriously, find a better example than someone who was racing, things happen at the track because of egos...turning up boost a lil more...pushing more n2o...dropping the clutch, revs to high...yada yada yada..

and i mean stock motors blow all the time too...

there was a guy in VA i believe that had a rod come throught the block while crusing onnthe highway...he then used a forklift to drop in a used motor from an echo...

then there is a fellow from PA that was driving to work when he had a rod snap...he had nothing done to the motor..other than a dealer installed intake... his sn is eXciteBox

i just showed three time more examples than you did...and they were all stock commuter cars...by your logic, your motor should be blowing itself up reall soon as it is over due....



come to me with real proof of these motors not being able to handle good amounts of boost.

(oh...side story here..i had a chevy 350, the worlds most tried and true motor, millions of them around and a well proven motor. it blew up while idleing on the dealers lot. has 0.7 miles on it...so there is not one thing you could say about a perticul;ar motor being weak from my experience the 350 is a weak, bad motor)


and as me not hitting 200hp...so what.
i've got heavy 18's, added drivetrain mass, and more show than go right now.

if you know enough about how the calculation of hp and torque are done, reaching 12psi at redline will not make you 200.

know what the power graph is, understand how a SC works, understand the ecu...then tell me exactly what i should be making at the motor, now do drivetrain loss and inertia problems and measuring techniques .
i tell you i am making 7% less than what i calculated i should be making...(and i know where to go to get that number to be less)

how inefficient is your set up???

 

what kind of problems?????
and can you tell me your mods to 14.0?????
thanks!
