Does anybody know why sts turbo dosent have a turbo for 3rd gen cars? I am thinking about buying one for my car but I am not sure if it is worth putting on a l98.

 

I cannot answer your question but....

I saw my first STS system on an '02 SS last week. I was NOT impressed. One strange thing was that the turbo did not have any oil lines.... The car was at a muffler shop and the owner was not there. How does this thing get lubricated??? I'm hoping (for his sake) that I don't know that there is a way to run a turbo without lubrication. Does anyone know?

Also, the supplied STS pipes had a strange necking down at the turbo discharge. It squished down to around a 1-3/4 inch diameter, then opened back up to about 2-1/2 inches.... what???

And the air filter..... it was absolutely filthy. Probably due to picking up everything under the car, including stuff hurled up by the rear tire....

Let me just say that I'm soooo glad I went the traditional route and put my turbos in the engine compartment....

 

No oil lines? Was it an old Aerodyne turbo (self-oiled)? I thought they went out of business.

 

I did not inspect the turbo to any detail to see if it had an oil inlet and discharge. All I noticed was that zero lines of any sort were run to/from it. I'm hoping the kit came with the supplied lines but the owner, for some odd reason, chose not to install them?? I really don't know. I could call him an idiot but I won't because there's always that chance that he knows something I don't...... I'm just trying to figure this out.

I'm also assuming the oil return line will need some sort of pump because the turbo is lower than the oil pan... Speaking of, the reason why the car was at the muffler shop was so they could attempt to raise the turbo by replacing the supplied pipes. When they were done, I watched them measure the vertical distance. It came in at a whopping 4-inches! They said they could not raise it much. Man, the first speed bump is going to take that sucka out! What a piece of junk, IMHO....

A guy here in UT has the mock up 3rd gen STS on his car. maybe he will post up. from what i know people either love them or hate them. I have heard that the lag sucks and they are not really worth it unless you get the upgrades. personally from everything i have read about them i would put mine in the engine bay

 

Most of the problems related to the remote mount turbos are due to people's ignorance with turbo systems in general. When set up right they do not lag and make good power, with excellent reliabilty. I'm speaking from 20k plus miles of experience with the RMT system I built for my daily driven Z24. It is driven rain, snow and shine every day of the week. And it runs consistant mid 12's on the weekends.

Willie, are you sure that RMT system you spied was an STS kit? While I have reservations about STS, their kits do come with a well engineered oiling system and half decent exhaust plumbing. I've seen more than a few hacked up RMT systems, which, I suspect, is from people trying to get on the turbo band-wagon the easy way when they really don't have the skills, knowledge, or ability to make a decent turbo set-up, remote mounted or under hood.

 

I think the RMT turbo working as well as people says it does is about as big of conspiracy as JFK's assassination. What I do not like is that it goes against every principal in modern turbocharging.

 

Not sure why it would be a conspiracy. I'm not even trying to sell anything. I started out laughing at RMT systems as well, but after driving one to work every day for the last 2 years I know A LOT more about them than most people do. I don't know how much proof you need that they can have good results, but here's a drag strip pass and dyno sheet for my Z24:

RMT system have there place, and in low boost systems on street cars, a good RMT will perform very similar to a traditional system.

 

Willie, are you sure that RMT system you spied was an STS kit?

Yes. The box the kit came in was next to the car, with "STS" written all over it, along with the pipes that came in the kit that were removed and replaced with hopes it would raise the turbo. I also saw their logo on some of the installed parts but cannot recall where now. I should have inspected the turbo in greater detail..... too late now.

Seems to me like STS may be partly to blame for some of the bad rap the RMT systems have. I can't explain the small 1 3/4" exhaust plumbing you seen on the '02 Camaro, but STS does build an oiling system for the RMT that apperently works well. It took me a bit of testing to make my own scavenge system work properly, but I've got it nailed down now. RMT systems are great for cars with little aftermarket support and cramped engine bays, such as my Z24. I built the turbo system in two days and drove the car nearly every day since then (except for the last two weeks- its been in paint jail!). I doubt I would have been able to do the same with a traditional turbo system (unless a GOOD kit was available).

Maybe I need to buy another IROC and see if I can have as good luck with an RMT system on it! It would be fun to try, plus I have my TT IROC I can use for a side-by-side comparision.

 

If the turbo was supposed to have oil lubrication, it wouldnt last more than 10 mins of driving without oil. And i agree, the rear mount turbo systems seem to go against everything ive learned about turbos, but dyno sheets and poeple that have them prove that they do work. It's all about velocity i guess. Maybe thats why the exhaust pipe gets small before the turbine housing, to increase exhaust velocity, since there isnt as much heat energy farther back in the exhaust system.

 

I know this thread is a little old but has STS done any further work on releasing a rmt kit for thirdgens.

 

I dont think that they plan on making a thirdgen kit but STS now has a universal kit. Check it out on there website.
