maby sending in turbo for rebuild?

[Alex Bland]

Ok i took off my 14b turbo due to smoke problems and im woundering if i should send in my turbo to just have it rebuilt for 275 bucks. Also im changing spark plugs and oil. I am hoping that this stops the smoking. it smokes on idle and just got worse longer car was on. and when im driving car it smokes a lot. blue smoke. im woundering what you guys think?

 

[Alex Bland]

I didnt mean to say rebuild just having the vales replaced

 

[the_mork]

Most likely turbo seals but it could have been that your oil drain tube was partially blocked. As far as what to do, it is your money but $275 is half the price of a new 16g and I'm sure you could find a good used one for $300 that would outlast your car.

 

[fwdmaster]

Get that rebuilt 16g in the classifieds

 

[Alex Bland]

i thought that 16g does not fit in my 5 speed because i have 16b

 

[JusMX141]

A 16G will directly replace your 14B.

If you're still interested in rebuilding your 14B, you're sending it to the wrong place....I can do it for almost half what you were previously quoted.

If the smoke is heavy under boost and non-existent at idle, I'd say that's a classic example of a worn turbine shaft seal, common on higher-mileage 14B's.

Turbine seals look like tiny piston rings. From a lifetime of short drive cycles and improper cool-down, the oil will begin to burn and stick to the turbine shaft around the turbine seal. As the burnt oil builds up more and more, it begins to shred the turbine shaft seal. I've literally seen these turbine seals come out paper-thin from such abuse! The thin seals cannot apply the outward pressure required to keep oil from passing between the spinning shaft and the center housing, and voila!....an oil-burning turbo.

Buy a good used 16g or have someone fix your 14b for cheaper than what you 1st quoted.

I sure wouldnt put that kind of money into a 14b.

 

[Alex Bland]

i took my turbo off and everything feels fine. So am i hearing this right i can just change out my 14b for 16g no problems.. do i lose power? also what 16g are you all talkin about like evo 3 16g that will fit right in or small 16g?

 

[Alex Bland]

turbo as 126k miles on it and no shaft play

The EVO III 16G will require you getting an EVO III O2 Housing. An making your exaust downpipe to fix it. I would get the Big 16G if your not looking to spend alot. It cost the same as the small 16G but you get more power. All you will need is a new turbo oil line. That everyone will tell you to replace when getting a new turbo on. An a return one there cheap. A J-Pipe will be needed. try getting an used J-Pipe.

 

[the_mork]

I was under the impression that 1gs did not need a new j-pipe unless the turbo outlet was ported and that it was not a particularly good idea to replace the drain tube because it is hard to get it to seal again against the pan and perfectly fine to re-use unless it appears in danger of rusting through. A new oil feed line is a good idea though for safety. Which 16g you want all depends on your goals, if you want a stock replacement with a little more potential then a small 16g will spool the fastest, a large 16g will be right behind it and is a good middle ground, and the evo3 16g will have the most potential. Also, I just used a ported o2 housing, I did not buy an evo3 o2 housing for my evo3 turbo.

 

[kittay]

For that much, might as well upgrade. You can buy 14bs for 100$ and less

 

[dlb21]

you would be alot happier if you upgraded to the 16g, not much more $$ and you get way better performance. Then you have a good starting point for future Mods.

 

[Alex Bland]

so big 16g would fit in mine with no mods? all i do it bolt it up?

 

[Alex Bland]

To my 5 speed

 

[Alex Bland]

i just need a direct change over i dont have the money now for any mods

 

[dsm-onster]

Yes, it will bolt right up. Fatherbubble is wrong about the o2 housing.

The small 16g is good for 38lbs/min. Many can extract 350whp out of that airflow easily. It spools quite a bit faster than the other 16g turbos. So if your goal is under this number this is the biggest you should go for a 16g.

 

[fatherbubble]

Yep your right. I forgot you could use the regular O2 housing on the EVO III. I would still go with the EVO III. For the reason have you pulled your turbo yet. There are real heavy. Even the EVO III is but its 2.5lbs lighter than the others. Way heaver than the stock one. When I changed out mine. I thought I was going to kill myself Trying to hold that heavy thing an bolting it up by myself. Heres the Difference betwen the Small an Big. Small spools up at 2800 an big spools up at 3000. Real big difference there. The EVO III is what every race shop I talked to recomend for street racing. Power an the spool time.

 

[Alex Bland]

Yes i pulled my turbo out so you have evo 3 without any mods because thats what im thinkin of getting without mods i just dont wanna blow up my motor.

You've never driven a small 16g powered car. My small 16g spooled at 2600rpms with my stock cams. A big set of cams like my fp2X cams pushed the spool back to 3300-3400 rpms. Every evo 3 16g powered 2.0L DSM with stock cams that I've researched, driven (2 so far), or had may hands on (one more) spooled at 3100-3200 rpms. 500rpms is big difference. My Big H1C holset spools faster than the evo3 16g. My old td05h 18g spooled at exactly the same rpm as several local evo3 16g powered cars with the same cams and stock long block. It's a good turbo for 350to 400whp with pump gas. It is very "bolton". But it is not the best turbo for the OPs goal; if this goal will be all he wants. He'll need to think about lots more money to invest if he wants to run the evo3 16g at a level that makes it a better option than a small 16g.

The small 16g is more efficient at 300-350whp flow levels. This means that it takes less energy to spin the compressor to achieve a certain boost. This helps spool speed greatly, because the turbine has access work available to put in the shaft to speed the spool. The shops recommend the evo3 16g turbocharger because it pushs more air at a level where a good dynoshop can make a real difference vs. an amature tune.

If your going to be happy with 300-350whp then the small16g is the fastest spooling easiest to bolton turbo that flows enough for your goal.

I'd go with the evo3 o2 housing with any 16g because any 16g turbine outlet port-matches the inlet of the evo3 o2 housing. But it is not neccesary.

I just installed a Small 16G on a customer's AWD- his 14B was dying, and he was looking for a little more power with lots of room to grow. This is the first car relatively stock car that I've gotten to drive before and after the upgrade from a 14B to a Small 16G.

I must say I'm rather impressed at how responsive that turbo is! I'm running 14psi (safely monitored) on the stock fuel system with the stock cams and SMIC. This is the ONLY 16G that will respond to acceleration like a 14B! If you want to build boost, all you have to do is step on the accelerator. It's completely different than what I'm used to!

 

[my98eclipsegsx]

so lets say I have a 98 Eclipse GSX with a 1st gen 14b turbo in it(dont ask previous owner did it) the EVO III 16 BIG would bolt right up? no mods just switch the turbo and plug it all back up?

 

[JusMX141]

That would be a direct swap, yes.

You will, however, want to port your exhaust manifold and o2 housing to match the inlet and outlet of the Evo III. Failure to do so will result in a rather large bottleneck in the exhaust system.
