Turbo ga16de Parts list needed

[B13Turbo93]

just lookin for some info on turboing my 1.6 need to know if stock fuel pump and injectors can take 8 lbs. i know i can use a 240sx maf but what years and can i use one out of an altima. looking to use a lot of second hand parts, except for new t25 or t28 and manifold.

Not sure about the injectors, but you might be better off going with a complete kit from www.hotshot.com

Take a look at the TSI GA16DE turbo kit. I am away on vacation currently, but plan to order one when I get back. The entry level kit is only $1400 shipped, but I read on Nissanforums that you'll need to be able to make a few adjustments and tweaks. For that price you have to expect that. You can later source a cheap used intercooler from a Saab or something and add it yourself. The main thing is that you have all of the hard parts that you need and don't have to spend weeks researching and sourcing all of the little fittings and lines. I have been researching the subject for several years and to me this is the way to go. The kit comes with a brand new Garrett turbo and a cast manifold too. No cobbled together crack prone deals here. We GA16DE owners are lucky to have this kind of support!

This was a viable source in the past, but unfortunately Hotshot is no longer in business.

The answer to your question is no. The stock 185 cc GA16DE injectors can't support much more than 2 or 3 psi of boost. The stock GA16DE air mass meter max's out at 5 psi. The 240SX maf meter is a good choice, but your stock GA16DE ecu won't work with it. The trick is to get a B13 SR20DE ecu and have someone like Jim Wolf Technologies [JWT] reprogram it for turbo use, which includes a daughterboard added to allow you to keep your stock VTC solenoid operating and match whatever air mass meter you choose [SE-R, 240SX Maxima, 300ZX TT or even a Ford Cobra unit]. You'll want to upgrade the fuel pump too. A 300ZX pump is great, otherwise a $100 ebay Walbro pump [either a 190 gph or 255 gph] will fit the bill nicely as well.

Cheers,

my buddy just built a d series crx from the ground up using a custom turbo kit and when all is said and done it's much easier to just go with a kit. he did buy a lot of decent parts that allow him to boost more and what not, but personally i would just buy a kit and build from there as need be. he's making 265whp on a built D series with more room to grow.

Agreed. Age has nothing to do with a thread. If the info can be added to or updated, I say go for it.

Here's how I went about the whole deal. I swapped out my original 90 h.p. GA16i [12 valve] engine for a '93 GA16DE [twin cam] into my '89 Sentra 4WD wagon. Then I set some simple goals for the standard 110 h.p. GA16DE engine. I wanted a modest increase in power and torque, not 250 h.p. like some people are after. For me, 150 h.p. would be fine. I simply wanted the power characteristics of my stock '93 SE-R, but with the 4WD of my '89 Sentra wagon.

Simple Goals

1. Spend less than $2,000
2. Increase horsepower by about 40%
3. Do it reliably without any expensive engine management electronics.
4. To not have to "custom make" and source every single part.
5. To not need an upgraded clutch or fuel pump. [In fact, I am still using the original 90 h.p. GA16i clutch and fuel pump].

So I opted for the basic TSi Superior kit for the GA16DE for $1399 shipped. They've gone up recently but are still only $1,469.99 HERE.

Here are a few pics of the pre-assembled unit with the cast manifold.






The basic Superior kit does not use an intercooler, but I have a very unique set of operating conditions that I drive my car in. This is my winter car and I drive it here in upstate New York during the frigid winter months only. My car rarely ever sees temps above freezing. I use it for ice racing and winter TSD rallying. Couple the freezing temps with only 6 lbs. of boost and as you can see, I don't really need an intercooler. I wouldn't recommend this route if you live in AZ though!

Engine Management

I read about how the GA16DE's original 185cc stock injectors were too small for even 2 psi of boost. The usual route is to go to 370's and an ecu reprogram. Everything involved in going that route would put me over the 2-k limit. I devised a plan to use standard SR20DE injectors, maf, and ecu in post #10 of THIS thread. I had a good running but rusty SE-R parts car donated to me so all of those components were free. I installed the SR's fuel system and drove the car normally aspirated to see how it worked. It worked out perfectly as described in post #24 of that same thread. To my delight, the A/F ratios were identicle to the standard GA's. I bought an Innovate LM1 wide band for all before and after testing. Even with this $300 purchase, I am still under the 2-k limit.

So I went ahead and installed the turbo system. The Superior system is designed for a '95 to '99 B14 GA, so I had to modify some of the piping for my '93 B12 combination.





It is connected to my mandrel bent 2" exhaust system [that I built 6 years ago when the car was n/a]. I refilled the oil pan with full synthetic oil, filled the fuel tank with 93 Ultra, added four BKR7E-11 plugs, and backed the timing down from 15 deg btdc to 8 deg. Before the first road test, I temporarily removed the hood and duct taped a fuel pressure and a boost gauge to the windshield to monitor things. To say I was really pleased would be an understatement. Boost was at 6 psi exactly as claimed and the A/F was 11.6 to 11.8 at WOT. Fuel pressure is raised to about 66 psi under boost, via the supplied rising rate fuel pressure regulator supplied with the basic kit. The car runs perfectly with no idling issues or flat spots. I shift it at 6-k. The once underpowered wagon now accelerates just like my '93 SE-R.

Mission accomplished.

I was in no hurry and took my time while installing the kit. Here are a few pics with some of the prep I did during installation. Although the manifold and turbo units come pre-assembled, I took it apart to check everything.



This shows the plenum roof of the cast turbo manifold. A small flow directing wedge helps guide exhaust gases to the turbine.



I opted to port match the exhaust elbow to the turbo's chamber for best flow characteristcs. In this picture you can faintly see the areas where I used a black marker to show where I had to remove material to match the turbo outlet [below].





This is how it looked afterwards.



Oil pan fitting installed and turbo unit mounted to the engine [below].





Oil pressure and coolant lines connected. At Wes' suggestion, I teed the turbo cooling lines into the factory GA throttle valve cooling hoses. It was simple and it worked out very nicely. I had to flip the lower radiator upside down to clear the flexible turbo intake pipe.



I modified the supplied 2" downpipe to mate to my existing 2" mandrel bent system.



I sourced the 3" MAF adapter and cone filter on ebay. Cost: $18.95 shipped.
