New to the world of fi, But I really want to go fi. Just need to know which way to go. I have heard turbo is better for engine do to the fact that the turbo is not always spooling when just cruising . I like sc as well. which way to go guys. And how much do I need to spend, I would like to go 2600-3500 bucks not much moree. Less if possable[?|]

You wont get a turbo for that amount. Cost me about 5200 + extras for a true kit. Without going into which is more reliable I would suggest u save ur money a little more and get Toms.

I'd agree with resty... The initial cost of the FI {eitherSC or turbo} is only the beginning of your expenses...

You get what you pay for....and the quality remains long after the price is forgotten ...!

This is deffenitly true, I can get jrsc for say 2650+install,I'll pay what I have to, I just thought there is a way to get a discounted deal, lol. Which is better though, turbo or sc.

From what I can see, the turbo is better because it uses "free energy". The turbouses the exhaust to power the air compressor, instead of using a belt. The super charger consumes energy from the moter to power the compressor. Most people feel the turbo is better, but the super charger is faster to install. Hope I got this right.

PS. First post [:D]

What Exactly do you mean by "better" ?? And what do REALLY want to HEAR ??

you didn't ask about dependabilty. check some of the threads, the jrsc has already proven itself. and if you have the dealer install it, it's warrantied plus it will not void your new car warranty. just a thought.

Really, I thought any such mod will screw me out of warrenty. And by better I mean which has less chance of hurting my engine. I love my svtf, and don't want to kill it prematurly.

It all boils down to personal preference,

A ROOTS SC (JRSC) has a little more torque on bottom end, but top end suffers due to cooling issues.... except for the new powerworks kit.

A Centrifugal SC (Vortech, ATI) has little bottom end power but builds power linearly as RPM increase, they make good horsepower but mediocure (sp) torque

A Turbo will make good power and good torque from about 2500 rpm and up. But there are just a few turbo kits that are CARB approved.

EXAMPLES:

ROOTS--- you pull out, it feels fast off the line but starts feeling less strong as rpm increases

Centrifugal SC- you pull out feels sorta normal and the higher you get in the rpms,s the faster and stronger it gets

Turbo- you pull out, hit the gas and it feels like you get shot out of a cannon, the torque from a turbo hits all at once and doesn't stop till you let off the gas.


I went turbo, and I love it... I hit the gas and my car gets instant torque steer (when it doesn't light up the tires) and I have a Quaife, Clutchmasters stage 4, and a Fidanza Flywheel to help keep this thing under control.

any other thoughts. anyone.

My setup is going to be pretty much the same as 03orangeSVT's. After all the threads on sc vs Turbo, turbo wins hands down for the power I want to make. So it's up to u to decide whether u want to spend mula. We have seen a few posts about making good power from an SC but when it comes to TQ, the SC didn't have it for me.

blah

Speed is a matter of money, how fast you're going to go depends on how much your willing to spend[burnout]

There is NO FI that is problem free, the reason the jrsc doesent stick its head up AS MUCH is it doesent make enough power to hurt anything , why spend 3000+$$$$ for that little of power

This just TOTALY IS NOT TRUE , If ANY Ford dealer instals any type of FI it WILL void your warrant , If they say it doers not make sure you have that in writing

Tom

The only way that will not void the warranty would be the FI install from the factory as part of the option.
Scion is doing FI with their TC- 220bhp with full warranty because factory install them.

This ISNT a Scion, Its a Focus and For will NOT cover anything powertrain related if it is FI , And again if they say they will get it in writing, you will find no one will put it on paper

Tom

The debate I have is based upon two things: cost and power.

I mean, a JRSC is around half the cost of most turbo setups, as far as I can tell.

But as far as power, a turbo has a lot more potential. You can do more with it. Yet that means that you may be sacrificing engine life given that the engine is working harder.

What I'm working on deciding is if the power I'd get from an s/c is enough for me, that it'll keep me happy, or if I'll regret not shelling out another 3 or 4 grand for a turbo setup. With an s/c, I'll prolly be faster than most cars with the exception of some turbo'd compacts, and that's something I'm okay with.

SVT-Chris, the turbo has more than just potential power. you start off with more before you even start thinking about going for MORE.
Plus you can drive around all day without even hitting boost conditions if you want,whereas w\a SC the added drag of the SC is there on the engine from the time you turn the key...

Once you get used to the power of WHATEVER you get, you'll start looking into ways of making MORE power.... people say they wont but they ALWAYS do.

To increase power on a SC means changing pullies at a minimum, on the turbo all you do is turn a knob, providing in both cases your tuner has left room for increasing the boost.

In my case the car was dyno tuned for 15psi, on the road it made 17psi, this is on 93 octane.
For the drive home I turned it down to 12.5 to 13psi, so I have room to turn up the boost due to the tune Tom did for me. AS a BONUS if I decide to run race gas I can turn it up a little bit more if needed. So far 13psi has done fine for me... thats still around 285 or so WHP[thumb]
