Bad turbo?

[Alex Bland]

I just got my 1991 eagle talon tsi awd and at first it ran bad because i think it was sitting for a year. Now that it runs better i took it for a test drive and found out that when i floor it it smokes blue out the back. This was the 2nd day after pulling it out and the first run it has had in a while. could this be a bad turbo? the turbo is working fine it looks like it go's right up to about 14psi. Could this smoke just be because it has not been ran for a while? Thanks

16g will bolt right up, and yes you have a 14b, 89-94 5-speed dsm's came with 14b turbos while automatics came with a 13g

 

[Alex Bland]

does 16g have more power and what else should i get to make that run?

 

[dropt4]

yes it has more power than a 14b, but not much on a standard 16g.. You would have to go to a Evo III Big 16g to see a better gain.. But they all bolt up directly to a 1g..

 

[Alex Bland]

ok so they bolt right in i dont need new headers or anything like that?

The 16G has more potential. To make use of its capabilities you will need larger injectors, a pump upgrade and rewire, a boost controller and boost gauge, a datalogger, and tuning electronics.

I'd go with 550-650cc injectors, at least a 190lph pump, a MBC, a pocketlogger and an SAFC for a 16G setup.

You would have to go to a Evo III Big 16g to see a better gain.

Not necessarily. The s16G and regular b16G are both definitely upgrades over the 14b.

Although, I would recommend an evo 3.

i think ill try to find a 14b to last me for now tell i have some fun spending money.

Yeah me too for sure.. I have the Evo III in my GST right now and love it.. Never ran just a super 16g before.. But you are right about it being a good upgrade over stock though..

 

[JDMath]

you can just put the 16 g without other mods but you will have to run it at low boost, after a minimum of larger injector and fuel pump upgrade and you can turn up the boost a little and get a logger to keep an eye on that!!

That would be a mistake. Buy the Big 16g now and run low boost till you get the cash for supporting mods. No sense in buying the 14b if you plan on upgrading in the future. But again, make sure you don't crank up the boost.

Ok so i think i found a ok turbo from a guy on craigslist BUT i dont want to get it here and found out he gave me a bad turbo. so this is where you come in. i know to shake the fan to see if it moves. but if there a way to see if it will leak oil or not r do i just need to trust him? 91 tsi awd

Ask him how much shaft play it has side to side and in and out. Ask for pictures of the exhaust wheel and the intake wheel. Look closely for damage.

 

[Alex Bland]

he is asking 100 for it so im hoping is some be good.

 

[pj91gsx]

Thats not bad for a good one that works with no shaft play. You could get yours rebuilt for not much more but Im guessing that this may be your daily driver and you dont have time. Am I right?

 

[Alex Bland]

wrong i cant find anyone i called and best place i found they want 350 bucks to re-build it.

 

[Alex Bland]

i dont think i can rebuild it the vales are fryed

 

[pj91gsx]

Oh. I dont know what that is. I just heard from a friend that someone around me rebuilds them for 125 ish. Though I had another friend get his rebuild for 300.

 

[1gDSM4g63]

Turbo rebuilds usually run at least $350 and what turbo are you talking about.

 

[Alex Bland]

14b turbo

 

[JusMX141]

I just ran into that problem with my 16G. Its 350 to replace the seals at a shop. I only found one good shop to do it.

Holy moses!

I do full rebuilds at my shop for less than HALF of that....I hope that seal replacement came with a jar of Vaseline.

Never ran just a super 16g before.

s16G = small 16G
b16G = big 16G
E316G = Evo 3 16G

 

[pj91gsx]

I didnt know there was a difference in an evo 3 16g and big 16g. What is the difference?

 

[delta448]

Mitsubishi turbochargers at Forced Performance

I didnt know there was a difference in an evo 3 16g and big 16g. What is the difference?

The E3 outflows the big16 by a couple lbs/min

 

[JusMX141]

I didnt know there was a difference in an evo 3 16g and big 16g. What is the difference?

-An Evo III 16G has thinner compressor blades and a lighter turbine shaft assembly to reduce rotational mass in an attempt to achieve a quicker spool and higher top RPM than the Big 16G.
-An Evo III 16G's exhaust housing has a 2.5" outlet compared to a Big 16G's 2" outlet.

My 16g came off a jdm motor, would that be a b16 or evo3 16g?
