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

Look at the part number on the compressor cover. It's most likely one of the following if it's a 16G:

49178-05200 = Small 16G
49178-01420 = Big 16G
49178-01460 = Evo II 16G
49178-01470 = Evo III 16G

If it's not one of the numbers listed above, Google it and see what you come up with.

Cool. Mines just a big 16g.

back to topic. alex, if you want to upgrade in the future its w/o doubt a better idea to get some kind of 16g instead of another dinky 14b whether its a s16, b16, or e316g (but go with the e316g it whoops ass). if you have the money and knowledge - go for it

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.

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

Although, I would recommend an evo 3.

Definitely go straight for the 650 range injectors assuming you have the means to control them (fuel control, like dsmlink to name a good one . I ran a e316g, 550's, 2g maf and stock pump and had a hell of a time with what I remember being similar to fuel cut. this old set up had no fuel control and made it hard to really push the car. As far as daily driving went the 2g maf and 550 combo worked ok until I hammered on it.

Now that I rum DSMLink and a walbro HP my 550's are the limiting factor in my build. 65o's would've pushed the limit of my turbo and made the 16g the weakest link.

P.S. If I had it to do over again I'd likely go with something from FP. Research 16g boost creep. Maybe an FP3052.
