Different Turbo Idea?

[cmikee]

Take a look at this web site

http://www.ststurbo.com/

It describes a turbo that is mounted at the rear of the vehicle. I think the principal is that it runs cooler because it's not so close to the engine. They sell kits but too expensive for me. I was thinking I could get a turbo from the junkyard and pipe it up the same way. Wanted to know if someone had seen this?

 

[Hopman]

Yeah. I saw them do an install on Horsepower! a while back.

There is enough room on a Ranger to do it, if it fits in place of the muffler.

Reasons I dont like it...

Turbo Laaaagg
More piping = more weight
Need to engineer some way to get oil and coolant to the turbo

give it a try. it worked for them. if we didn't do things like this; we'd all be driving non-lifted, non-upgraded stockers to the golf course and tennis courts instead of slogging around the great outdoors.

Can it handle it?

I like the rear mounted turbo idea.
I might try it if the kit will plumb everything out.
Can a '99 Ranger 2.5L engine handle an extra 100HP?
I put in a detroit trutrack posi so I'm not worried about the diff.

What do you think?

squier turbo systems is based about 5miles from me so of course i think we have more of those damn ret's (rear-end turboes) per capita than anywhere else. all i can say is at least it's not one of these: http://cgi.ebay.com/HONDA-ELECTRIC-...1632634?pt=Motors_Car_Truck_Parts_Accessories

A properly sized turbo will not have lag.

An extra 30lbs? Big deal.

It's called oil lines and a scavenge pump, don't need coolant.

The remote turbo setup has proven to be very effective.

You don't live far from STS BlackBII, go take a ride in one of their cars...

you must mean that "a properly sized turbo will not have much of a lag" because any turbo small enough to "not have lag" will be proportionately small enough to the engine that overall peak boost would suffer incredibly because it would need to be tiiiiiiiiiiiiiiny like the size of a golf-ball

all turboes hav lag. the only forced induction without a lag is positive displacement superchargers period its not an opinion its just the dynamics of it

Don't be a smartass, a properly sized turbo will not have unacceptable lag. Better?

ideally you want the turbine side of the turbo as hot as possible without melting down and the compressor side as cool as possible. that is what snail wraps are for. and yes you can get a turbo from a junkyard and do that if your willing to upgrade your fuel system as well. you might want to look into a turbo off of a big cat diesel if your looking for big power and dont mind a little lag

A remote mount setup will always have more lag, regardless of the size of the turbo. I've ridden in one of their cars(My dad's friend owns one), a Vette with twins...and it had a decent amount of lag. I've seen their setups up close and in person, and while they do good work and make it look pretty, the remote mount setup isn't as efficient as one with the turbo mounted closer to the motor.

30 lbs is a big deal...if you're building this vehicle for performance, which is probably not the case here...just some guy that bought a truck rather than a sports car, and for some reason wants it to perform like a sports car..

No coolant? Well, your shiny new $1000 turbo is not going to last very long, unless of course if you bought one of those 'ebay' turbos that run for ~$200, in which case it'll have an even shorter life. If you are spending a good amount of money ($2000) on a REAL turbo, having it last more than 10K miles is a priority.

Remote mount setups are definitely effective, any forced induction setup will be, the problem is, they are not as effective as it should be, because the Exhaust and Intake charge have to move farther, losing velocity and heat is lost via the exhaust pipes in the space between the motor and turbine wheel, further making it less efficient



To the OP, I would be careful getting a turbo from the junkyard, you never know what condition it will be in. You could always have it rebuilt, but that requires you spend money. Also, you will need to upgrade your computer, ideally stand alone or an LA3 from a Turbo T-bird, and also your fuel delivery

Look under the hood of a semi or a diesel pickup, you WON'T find a water cooled turbo! Most turbos are not watercooled.

No, it will never be as effiecent as a front mount because of heat loss but the difference is marginal at best, turbo size has everything to do with lag, A properly sized rear turbo will have no more lag than a properly sized front turbo, it has a little less potential of course, but for the average Joe it's not a big deal,

I am new here but I do know a little about turbos and heat does not make power. Think of it this way you can put a torch to the turbo all you want it will get hot but not move. The heat in a turbo comes from the exhaust and slowing the flow of hot gasses.

True. But you WILL find an oil cooler.

The point I'm trying to make is; Why do a remote mount, when you can do a front mount? Front mounts can be cheaper, more efficient, less prone to damage...etc

Using some header wrap can help with the heat losses.

i used to drive a truck for 15 years,the cooler used on big rigs is an aftercooler, as it cools the air charge after it comes through the turbo,remember the engines that are in big rigs make all their power in a very narrow band roughly between 1500-2000rpm,ive seen the reviews on the sts turbo system,and would have no problem trying it on my ranger if i could,unfortunately the geeks at the california air resorces build will never let that happen
