I'm interested in the TSI Superior turbo kit for my GA16DE powered Sentra. Is there anyone that's got a picture of it installed on their Sentra? I realize there will be some fabbing necessary to finalize the installation. That's no problem and for the great price, you have to expect that.

Well I found a picture of the GA16DE kit. The only difference is I will be using an intercooler.



I have a plan for engine management as well. I wrote it up on Nissanforums. Check this out:

I have come up with a new idea of how an economical fuel system upgrade could be "engineered" at home.

I invite the more experienced boosters to shoot all of the holes in this they want. It is a suggestion and if someone knows of a reason it won't work, please let us know.

It is generally agreed upon that the stock 185cc injectors are a major limiting factor for boosting our GA16DE's. So they have to go. Changing to larger injectors mandates an ecu reprogram or stand alone fuel management system. Both are expensive.

A new idea perhaps?

Lets's take a minute and compare the stock engine management systems and fueling requirements of the B13's GA16DE and SR20DE engines. Both get about 30 mpg in the same car. Both use an air mass meter to measure the amount of incoming air and adjust the mixture acoordingly [within a window of parameters course].

Ok, with that said, consider that the 30% increase of power that the TSI Superior [T20] kit is advertising will bring a 110 h.p. GA16DE up to about 140 h.p. The SR20DE ecu is programmed to support exactly that. See where I'm going? I'm not saying I've got this all worked out, but this is starting to look good. I have a good running '92 SE-R parts car. My idea is to swap over the SE-R's ecu, the four 259cc SR20DE injectors into the GA's fuel rail, and the air mass meter to keep the SR's ecu happy. My guess is that the GA might be a bit rich when not in the boost. In addition to the small amount of correction the stock ecu can make via the air mass meter, perhaps the rising rate fuel pressure regulator [which comes in the turbo kit] can be adjusted down enough to correct this. Yes, you'd need a wide band to check this as you go. Remember that the smaller GA16DE engine will be drawing less air than the SR20DE would be [through the SR's air mass meter], so that in itself should lean the mixture accordingly. It might not be spot on, but it should be close enough to be able to fine tune with regulating fuel pressure.

What do you think of my plan? Sound reasonable?

sorry maybe im missing it, but you are proposing that you would upgrade just to the larger injectors and ecu? while that might work, theres got to be differences between the 16DE and the 20DE motors, as far as timing, off throttle response / and cruise characterisitics. not to mention you would be keeping the sensors and motor the same. injectors, ecu and fuel pump from the 20de would be a good start though, although you would really need some sort of piggyback computer to fine tune your car. good luck let us know how it goes

I have been looking at the turbos as well. What you propose is way to involved to even want to attempt. You will run into issues with sensors, the air-conditioner, emissions, etc... the wiring diagrams are not the same.
That said, using the larger injectors with an APEXI Neo A/F programmer may be possible but difficult to tune ultimately.
I believe AEM has a stand alone ECU system for our vehicle, although pricey, around 1200 dollars, you get a deal on the turbo so why not? then run whatever injectors will fit and map it on a dyno with wideband, which you'd have to do anyway with the proposed switch. Besides, you do not want to wire a whole car's ecu.

true!

I can only second what everyone else said the ecu controlls way more than just the fuel ratio. Power to you for finding an inexpensive turbo kit but just dont be cheap with it otherwise in a month or 2 you will be back asking how to fix your motor.

Update time

What I proposed was actually right on the money. There were no issues whatsoever with sensors, emissions, etc. For those just reading this thread for the first time, we are dealing with an OBD1 era 1993 B13 Sentra GA16DE engine and harness. I swapped it [and the complete B13 engine, ecu, and harness] into my '89 B12 Sentra 6 years ago and have just added a turbo to it. Read on.......

I checked the ecu connector pinouts for both the GA and the SR engines in the '93 factory shop manual and found that the SR20DE and GA16DE ecu's are pretty much interchangeable. The only small differences from my GA ecu to my SR ecu were that the SR ecu has 3 extra pins for items that I don't have [or need] on my '89 Sentra anyway. They include Canadian daytime running lights, A/T torque converter lockup, and A/C. Of course you lose the GA16DE's VTC switching signal with an SR ecu [because the SR doesn't have VTC] but that's easy to control with an adjustable rpm window switch. Anyway, I swapped in the four 259cc SR injectors, the matching SR air mass meter [very important-the GA airmass meter won't work with the SR] , and the SR ecu into my GA16DE car. But before I changed anything, I monitored the air/fuel ratio on the stock GA16DE with an Innovate LM1 wide band so I could see what the factory air/fuel values were during different driving conditions. The stock GA16DE ran at between 14.2 to 14.8 pretty much all the time at cruise. Wide open throttle would see it richen up all the way to 11.8 at about 6-k. Part throttle of course, was in between depending on load.

Now with the SR components installed, the fuel curve is exactly the same. My logic earlier in this thread [in guessing that they would be very close], was correct. So now that I have the engine management sorted out, I went ahead and installed my TSi turbo kit.

Finally! someone took pics and documented their GA16DE Tsi Superior turbo kit!

I have documented the install [with plenty of pics] on page 2 of THIS thread.

So basically, as long as you swap in the 1993 SR20DE's ecu, air mass meter, and 259cc injectors, it is all plug and play.

and he proves us wrong... good job we never can find out new stuff if we dont try

Wow! As long as you're tuning with wideband o2 sensor and you're using the SR parts, you can pretty much tune anything given enough time. Prolly start out rich so that's safer than starting out lean. Don't overboost on crappy pump gas though!
Good Job!

Thanks Dan,

I plan to stay at 6 psi and run it on 93 octane. The icy cool temps of winter are the only time I use this car. I'm really impressed how well it runs.

what fabrication is needed, and what tools would i need to install this, besides the obvious (socket wrenches, screw driver)

this is my first post to this site, and im really new to upgrading.

currently i have a stock GA16DE nissan sentra 94'

Hello Spike,

I am a former career Nissan mechanic so I have access to a shop that is quite nicely equipped. It's hard to list every tool I used but beyond the basic hand tools, you'll need a center punch, drills, die grinder, razor blades [to scrape gasket material], and a tube of gasket maker to install the supplied oil drainback fitting into the oil pan.

Next, because my car's a 1989 B12 model I knew going in that the supplied front exhaust pipe was not going to fit my car. I used a hack saw, an electric angle grinder, and a mig welder to adapt the front pipe to my existing exhaust. Any muffler shop could do this for you inexpensively if needed.

You didn't say what year your car is. If it's '95 to '99 B14 model Sentra the kit should bolt right up, but if it's a B13 model ['91 - '94] you will have to juggle and modify the charge piping to fit that model. The reason for that is that the intake manifold is slightly different between the two. If you're brand new to working on cars, this might not be the best project to learn on. Seek some help from an experienced mechanic if you need it.

Remember, as with anything that's custom or aftermarket, it will need a some tweaking to make it all go together properly. Trust me on this, I've been modifying my cars for almost 30 years.

Good luck!

thanks for your advice. im problobly not experienced enough for this type of work yet, ill look around for a different car to start a simpler project with.

New User

will this turbo kit fit on a 96 nissan 200sx se

blownb310

Yep, it is designed specifically for the '95 to '97 B14's with the GA16DE. Take a look HERE.
