single turbo reliability
 

hey guys i know that there is a single turbo section, but honestly people respond faster here and technically this is an engine topic. so i was just wondering what kind of reliability issues are we looking at with a single turbo application, and generally what would the supporting mods be. i ask because i am looking into picking up another 93 with a single already installed. i am prepared for work, and time, and money. but i was just curious

thanks guys

A single turbo should be more reliable than the stock seq twins. Just need supporting mods as per increased hp level.

Greddy T78 13 Months On 17lbs And Counting, Any Questions?

Your sig is sexy.

The source to most engine problems were cooling issues or the seq. turbos doing some wacky business. Thats about as much as I know so if someone can help him out please chime in :) .

Built correctly its a lot mo reliable than the stock twins. I did 20k miles on my single built by turblown.net before swapping to a new setup...

/\ I HOPE TO HIT 100K.


thanks im changing the color again

Didn't the FC do well with a single turbo or were they about as bad as the FD with twins?

It's all about the tune also, dont forget that. Swapping to a single with all the proper mods will move out a lot of heat out of the engine bay, which is a good thing. I was very pleased going to the single, wish they would of came single stock. Saying you have a twin turbo does sound cool though. Just my opinion

It depends on the tune and the build (if you're on a rebuilt).

But just remember, any cold night, basically all it takes is one spike and say goodbye. Even if the engine was built by a top notch shop and the tune is by god.

just dont go cheap on the right turbo (not those ebay ones) Motor, Tune, FUel, Spark.



Tune, Fuel, Spark, Motor (in order from most important)

keep these 4 in your head

I hate thinking that, if you have the money to buy a FD. You should have the money to build it right, and use good quality parts. Thats why the forums are here, to help you from getting bad quality parts or letting you go down the wrong path. Thats why I am happy this forum is around, great info, good people, and lots of help!

agreed +1 :icon_tup:

(i ask because i am looking into picking up another 93 with a single already installed)



I dont think he would have a choice for now since the FD he is planning to purchase already has a single installed

OMG your sig is also sexy!

most people do wrong with the fuel upgrades..knowing the proper injector combinations with your setup is pretty important. in my opinion a pfc and wideband will help make sure you get everything the way it should be, to the tee. alot easier to tune correctly with these also. and dont forget about ignition break up under high boost.

just make sure you research alot, regarding whats best for what your running.

not to go off topic but this is one for the guys experience in going single turbo

if going single CAN be more reliable depending on all of the different variables: if the car was tuned properly, motor was well built, and the correct supporting mods are used, what would essentially be the most reliable single turbo?

i kno
noob question

Are you using any type of water injection for 17lbs? what octane are you using?

Just use your common sense. Get a quality proven turbo kit and the supporting mods. There are too many variables that affect reliability to say one is more or less. The only thing I can think of is one fuel pump instead of two. That is one less thing to go wrong. The more power you want the more factors play apart the more that can go wrong. G

There isn't really a difference in reliability from one turbo kit to another, as long as you don't buy junk. What people really mean when they are saying reliable here is that when you go single there are less parts to malifunction. Single conversions take the rats nest and a lot of other things out that give people problems.
Once you get your car, you should come back and list ALL the mods on it and ask us if the previous owner left out anything important.

If for no other reason, a single turbo setup is more reliable b/c of the countless bs vaccum lines and solenoids that gets eliminated in the process. I still cringe when I see an FD rats nest. N I G H T M A R E.

Single turbo would be more reliable. Even if you are on the same motor that had the twins on it. Like someone said earlier...it removes the rats nest, turbo control actuator, worn out twins, etc.

If you are going to run any more than 10psi on a single you would probably want a rebuild before doing so.

93 all day no other cooling product except my engine & cooling temps are cold as hell, daily driver so i maintain the hell out of it! sparkplugs onece a month, oil change every 2k miles, & recheck the engine for any leaks or anything, but the motor is strong thanks to the custom apex seals i got! FROM OTHER TUNNED CARS IVE SEEN. even with a built motor/dowell-pinned. The internals cannot handle over 25psi without racegas (or some sort of high octane gas). the 93 octane cannot suppress the detonation or keep the motor from cracking. but ive seen things on here that people deny it will never happen. As long as you have the right fuel/spark its all on the tunning!


Its sad but ive seen alot of people go the cheap way & end up paying for it. especially since theres certain parts that you just cannot buy used (clutches, beaten up turbos).

in the triangle theres 3 words [ power, money, reliability] you can only have 2. PICK
