I get all bothered when I see that kit too. Then I realize that the rising rate pressure regulator will not be the answer to proper engine management for our engines. Other than that it should give you little boost in torque and hp. One downside is that you will need to use premium fuel from now on. Also note that the picture of the kit is generic. The kit shown has a blow off valve that we couldn't use with our cars which are air mass meter equipped. Looks like a Honda manifold in the pic too.

Is there anyone here who has bought and installed on of these kits? What have your experiences been?

IF THIS SYS. IS OK WITH 97 SENTRA GXE 1.6 ( As advertised ) U probably have to spent another $1600-$2000 for other upgrades...SO give a take $5k clean if u're moddin u're Nismo...My personal opinion turbo is the last step for the ga16...

yeah a T20 is a bit small. But budget is budget, you could make the chagne to turbo car and then upgrade things.... but the thing that gets me is tuning - aside from AEM (1200 bucks) or megasquirt or similar (inexpensive but not plug and play) there arent a lot of options - send an sr20 ECU to JWT and 550 will give you a setup, but if you want to change turbos later you will have to pay again for a retune.

That's why for me the tuning route you plan to take is a big factor in choosing a turbo setup.

I like changing things so I doubt I'll do JWT. I am too broke to drop the coin for an AEM,,,, so I will probably give myself headaches and try and build a Megasquirt standalone ECU that I could plumb nifty things into like wideband A/F controller and retune as I change my setup.

But thats a later story, right now my turbo project is just a pile o parts.

Wheres the injectors? what ecu are you going to run or are you going to get a wideband a SAFC? You need to do alot of research before you turbo the car.

Yes we know that 2dr_Sentra, thank you. It has been discussed many times over the past three or so years that we have seen this kit become available. The economical "foot in the door" price of $1400 to boost our GA16DE's is very attractive to alot of us on these boards.

The result of all of these discussions regarding a safe reliable engine management for this system is that there are many options available to us, only none of them are cheap.

But us frugal GA16DE owners never give up on our quest for cheap reliable boost. So lets continue to brainstorm here. 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. at full throttle. 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 [which is about 98% of the time for most of us]. 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 GA engine will be drawing less air than the SR through the SR air mass meter, so that in itself should help in that regard.

Footnote: I know that the B13 GA16DE's ecu cannot be reprogrammed, and that the standard operating procedure is to aquire an SR20DE ecu and have it reprogrammed for use in our boosted GA16DE's.

Question: Does this mean that a stock SR20DE ecu will plug right into the GA's ecu connector [with it's matching air mass meter] and run? This whole idea revolves around the anwer to this question. In other words, is the order of the pin terminals similar on each ecu? I'm not concerned with the lack of the variable timing control signal as that can be connected with an rpm switch if need be.

Thanks,

Mike

yeah i understand. But im not even going to say anything its not worth the chaos it will start.

yes the ECU can be swapped over, pinout SHOULD be the same (although I swear there are like 50 different B13 versions with weird little things different between them ;) )

Dang I wont say anything except, if you wanna try it, I will watch. But I suspect there might be some other differences, the sensors for example, that will make the sr20 ecu freak out.

I checked the pin terminals between the two in my factory manual. They are pretty much right on. There are very few terminals that don't match and they aren't needed in this case. One example is the signal that turns on the coolant fan. I used the B12's stock thermal sensor system when I swapped the GA16DE into my 4WD wagon.

Yes possibly. I was thinking about that too. But I've got an entire SR20 engine, so I have all of the sensors as well.

The nice thing about using the SR's management system is that we should now have room for expansion in our fuel curve. In other words, the injectors and the air mass meter are no longer the limiting factors. We should now have some "breathing room" for tuning, like other brands enjoy.

use the sr20 sensors and adaptors or what not to put them in the ga16, or if you can read schematics, trace the wires by the color and see if they corespond to being ground, hot, resistance and what not, then splice the ga16 electrical plugs into the sr20 wiring... if you do it all correct and take uyour time and study it all really good, it would be basically a plug and play, then just get pcm reprogrammed for ur turbo and such.

what about splicing a set of injector into the harness and haveing a custom upper intake with longer runners and tapped for the 2nd set of injectors, then run an adjustable press. reg. and even possibly a way to turn of the second set,...hence like running a high rise intake on a small block versus, a dual plane or low rise...

haveing the option to run both or an either or setup(i.e. upper set or lower set which id call dry or wet injection )
could give us self tuners the option to adjust how the car drives according to the way we are driveing the car... for economy, power, or nasty...

of course ud have to run two fuel rails and all that

but itd be cool and all.

and lots of possibilities too
what ya think??? thats 259cc time 2 is 518cc???

Wow that's shooting for much more power than I am looking for though. I plan to keep this as simple as possible. I've got an Innovate Motorsports LM-1 wide band setup to help me tune it safely.

The Stock SR20 ECU plugs right into the the GA harness. its the same plugs. That is why you obtain the same year 1.6 and 2.0 car ECU. Now JWT has wired the Pin where the VTC picks up teh signal out of the harness and wired it to the board in the VTC switching unit they offer in the ECU package. I paid 800 total for my conversion ECU. They told me they can program the 95 MAF that is bigger than the GA's MAF. you must custom wire that in and they program it to run the voltages in the 95 MAF from the 200sx. or they can run the Cobra MAF also. They can do anything. run the injectors. whatever.

Take another look at the picture in the first post of this thread. The intercooler is in plain sight. The JC Whitney kit is $300 more but has the intercooler setup. BTW, the best place [price wise] to buy the non intercooled kit is Pro Street Online. They have it for $1399 with free shipping [$154 cheaper than No Limit Motorsports]. As has been mentioned already, the only reason anyone would buy the non-intercooled kit is if they had their own intercooler [from a Saab or whatever] to install. I would imagine you could get away without one if you were going to use your car for ice racing only. With ambient temps from 20 to -20 F you'd be fine. ;)

Thanks Chris,

Yes I remember reading a post of yours describing your setup in another thread. I wonder though, why JWT doesn't suggest using the SR20DE air mass meter? It's bigger than the GA's also and is already correct for the SR ecu being used. In fact it can handle up to 250 h.p. I plan to use one in my setup.

SR20DE MAF 91-94 Sentra SER, part # 53J00
50mm 250 WHP-----------Bored 54mm 290 WHP

Andreas Miko has a great thread about air mass meters here: http://www.sr20forum.com/technical-information-library/149465-maf-size-part-s-whp-output.html

BTW, the whole point of my setup proposal is to avoid spending the $550 - $800 for an ecu conversion. If all else fails though, it's nice that we always have that option.

The kit pictured is not for a GA16 for the record. Furthermore I have YET to see the actual GA16 kit in a photo. I want to see the manifold and downpipe setup...

I see we are still trying to re-invent the wheel as far as fuel management and whatnot. I have said it before and I will say it again. DO NOT BE CHEAP ON THE FUEL SYSTEM! I appreciate wanting to do this within a certain budget, spend the $ on the fuel system and skimp in other areas! Log manifold welded locally using weld els from an industrial supply house (cheap parts). Cheap DIY IC piping, used turbo and injectors. Honestly you can easily turbo your car for $2000 or less and make over 200WHP!
