Why is this kit so cheap?

Thats just a pair of used turbocoupe turbos. There is no Kit to it. I can pick tose up for $75 each at the local yards.

edit: Actually, I think those are the chrystler turbos not the TC ones. Could be wrong though.

so they are no good?

meaning, useless for our applications? I wish you didn't have to have special headers for turbo setups cuz it would be so much easier if u didn't

Paul, I've seen junkyard TC turbo conversions on fox body mustangs. Takes some fabricating but they started with 2 TC turbos, took shorty headers (you could use stock if you had to) flipped them over and switches sides, so the collector points up and forward in the bay. Then you would just weld the turbo flange in and run your piping.

Well I dont think their worth what they are going for. Point being is that all they are is a pair of junkyard turbos. Kind of looks like they want you to believe your bidding on some special Mustang twin turbo kit but in reality, the turbos are probably the cheapest part of a twin turbo buildup and thats all they are selling. There is alot of plumbing to fabricate and stuff like that. Its not like your gonna buy these turbos, bolt em on and go. And if they are the chrystler turbos (which I believe they are), they aren't all that popular for a 5.0 TT setup since they are a bit small. I have seen it done and pople have made them work but they aren't optimum.

Go over to the forum at turbomustangs.com and look through the DIY/Junkyard buildups. You will quickly get a feel for how much is really involved. I dont claim to be any kind of expert but I am preparing to do a blow-through TT setup on my 92 hatch so I've done quite a bit of reading up on the subject. Unfortunately Im still collecting parts and havnt got down to the actual fabricating yet but Im getting close.

you just described a supercharger and yes supers are easier. IMO I would go super over turbo, I'm gonna get attacked for this one but thats my opinion because, you can get equal power from both a super or a turbo.

Sure you can get equal h/p from each…but a turbo is going to have a fatter torque and h/p curve than a cetri supercharger by far.

This also means you can run a more reasonable rear end gear for freeway use…which will actually help the turbo/turbo's spool quicker.

Assuming the tune is correct, you should be able to squeeze out more h/p safely on a turbo.

Most turbo's are intercooled…which makes it safer to run more boost on pump fuel.

You also don’t have the excess forces applied to the crank on a turbo as you do with a supercharger.

Just my $.02

they are internally waste-gated, which some people dont like. also they are used? i dunno man.

I was just going to ask this question. Good post!
Anyway, Turbo and super with equal PSI, say 5psi, the turbo will make more power and torque and do it at a lower rpm?

will make more power and torque at same psi, cause its using wasted exhaust gas to turn, instead of being a parasitic drag on the motor. like a monkey on your back, superchargers are less efficient than turbos, as far as at a lower rpm... it depends, roots blowers make boost and hp/tq off idle, centri's make it later, turbos, it depends on what size you use as to when they will spool. turbos> superchargers.

oh and btw, those are t3's i think chrysler turbos were smaller t25's i could be wrong though

No question a turbo will make more power in the long run, but there's also no question that they can be a huge PITA, and be much more expensive.
Figure you can get a S trim on your car for Roughly $2500, double that for a quality turbo kit.
As said above, the piping/ headers can get pretty eloborate and expensive, couple that with an intercooler and cost is way up there.

 

[Mark89coupe]

How can a turbo be a big PITA?
It sounds like an easy install.

 

[D347643]

you dont need special turbo headers, flip some shorties around and aim them toward the front. Depending on which side you want the turbo on just order a single shorty from bbk or whatever.

5.0 computers don't always enjoy turbos, and they can easily put the car into the DFI zone, that's no walk in the park.
But worst of all the fittment is a serious issue. There's very few kits that completely fit perfect without having to take the car to an expert to get finished, i think helion is one of the high end kits that does fit, but it's gonna cost you.

If a turbo was just a slap it in and drive on a mustang, more people would have a turbo than a supercharger.

I make no argument on power, because i see first hand how powerful turbo mustangs are, but i also see the cars all land up at kooks to be done right, and you aren't leaving there until you are in debt.

Cars are all slightly different, companies use mach-up cars and engines to build the kits, unfortunately sometimes they aren't perfectly the same are a customers car, thus, things don't always fit.
Where's if there is no real piping on a supercharger, just bolt it up, make a few fuel adjustments and you are off.

Goto one of these turbo mustang sites, see how long everyones cars are down for turbos, i bet some are down for weeks even months.

Turbo street 5.0's are for people that take this hobby extremely serious, and have probably been through a couple of other setups, they are not a rookie mod.
Not sure i've ever seen a guy with a turbo 5.0 as his DD. But there's dozens of guys that do it with Supercharger.

There aren't a lot of one-size-fits-all answers to the questions being asked here. The biggest single piece of making a turbo set up work the way you want it to is having someone that knows what they're doing help you with sizing. And that's never done with the junkyard set ups -- a lot of folks out there think turbos are like boxer shorts -- just grab a pair and go. If you want a nice set up that with minimal lag, quick spool, and lots of torque down low it takes a bit of design, or lucky guessing.

Besides Paul -- most any of the twin set ups out there are more than capable of causing that stock block to pull a Paris Hilton on you --- laying open with a big split right down the middle. If you're serious about twin digit boost with turbos or superchargers a block upgrade is a must for longevity.

I know but turbos are so much cheaper than superchargers - i guess until you get into the long run - i'd way rather have a supercharger, i love the whine, the look, and the power, but i hate the price - I like the way my intake looks, so a twin screw type is out of the question (kenne bell or other) this is not all just for go, because i wan't it to look sweet too... But the cheapest supercharger kit is soooo much more than i can spend - here comes the saving game - H/C/I was more than i could spend too but i saved up for that - i guess next summers money is a supercharger!!

Paul, not sure where you get that info, or if you read all the posts above. But turbos are by far more expensive to do.
Look online for a turbo kit, they are almost all $4000+.
