alright need a new turbo

[SRTthis]

thinking about upgrading from my stocker to a 16G. what else is needed? can i run stock injectors on 14lbs with a 16G and a 190LPh fuel pump? can i run the stock side mount also???? anything else i need? other then tuning stuff?

im trying to put as little money into this thing as i can. im still working on getting my lightning up and running so untill then the DSM take a back seat.

at 14lbs of boost you will be fine with stock injectors. the stock intercooler will work as well. Before upgrading the turbo you should follow the upgrade path as described on this website. by doing all of the upgrades up to the turbo you will notice a significant power increase. once all that is done... put a 16g on it. i would start to get nervous after 14 psi. Fuel cut will become a problem with the stock injectors and ECU. So until you upgrade those i wouldnt go much over 14psi.

On the dot. You will not need any tuning instruments until you upgrade your fuel system.

Yeah, power doesn't just come from the turbocharger, but from how well supported it is.

Matter of fact, some tuners have upgraded injectors, intercooler, exhaust, air/fuel tuning device, and seen great power gains on a stock turbo.

But hey if you rather do the turbo first, you'll be fine at up to 15psi, beware for fuel cut after that.

And yes, you can run the stock sidemount forever if you feel like it. Would you make more power and higher timing with a FMIC or upgraded SMIC, definitely.

 

[chavez408]

would you really upgrade your turbo, without upgrading your stock boost gauge first to something more "realiable"?

 

[SRTthis]

so you think i should just get a new stock turbo since this one needs seals?

 

[2gGSX]

It sounded like you just wanted to get the car back on the road, not really make an upgrade. Go for the stock replacement.

 

[SRTthis]

ohhh no... if i wanted to upgrade id sell the lightning and go nuts... who sells stock replacements dirt ass cheap???

This is not on the dot like someone said. Fuel has nothing to do with fuel cut. It all depends on how much air you are pulling in and if its to much for the maf. The 1g maf fuel cuts like a punk past 15psi. You will need a 2g maf, 3g maf, or a blow through set up to fix the fuel cut. Or a fuel cut defenser which I dont reccomend

I actually said fuel cut will be a problem with stock injectors and a ECU upgrade. Without and AFC, DSM Link or anoter form of upgrade to tune larger injectors the car will fuel cut soon after 14 psi. You are correct the ECU will fuel cut when it is pulling more air than than the injector duty cycle can keep up with (too much boost).

I didnt realize you are just trying to get the car back on the road... go find a stock 14b cheap somewhere and you should be set.

Unless you've already got a 14B, it's probably cheaper to get a new 16G. With a 14B, you'll have to buy a used one and have it rebuilt. In the end, it will come out to cost just as much, possibly more, than a 16G.

I don't know where you're getting this. Not every 14b is absolutely fubared. At most they'll have a crack starting near the wastegate passage or in the turbine housing, however this will by no means keep the car from being undriveable.

I never said they were FUBAR and I never said undriveable. Reread my post.

I said since the 14B would have to be bought used, you'd have to:
1. buy a used 14B
2. pay to have it rebuilt ($345 to start through FP)
For most people that sell their 14B turbos, it's pointless to rebuild it since it will cost more for the rebuild than they'd ever get in resale value.
Combined with the price of the turbo in the 1st place, you can find a brand new 16G for only a little bit more.

Get the 16g, since you have to replace it anyways. Regardless if you "need" it or not, it is more capable than the 14b. If you decide one day to get a boost guage and controller, you can go up to 16psi. I was running 16psi all day when I was running my 16g on stock fuel parts.

I bought my 14b used from a junkyard for less than $130 and never paid to have it rebuilt. There was no shaft play and only one hairline crack in the turbine housing inlet, which was able to port most of out myself. Four years and 60k miles later, still no shaft play and happy boosting.

 

[hereitcomes]

Every o2 housing or turbine housing will have some sort of hairline crack or fracture. The heat buildup is tremendous.

desided to stay stock for now untill my lightning is back up and running... whos got stockers for cheap?!?!?!
