They are good.

What do you want from the mod?
Are you looking for big HP?
Then cams will give you more of a gain than the ECU.

What the ECU provides (for the SE-R) is a better map (2-5hp), higher rev limit, and removes the top speed governer. It also seems to get rid of the 'good day/bad day' way the stock ecu cars tend to run and improves throttle response.

It can also be upgraded if you go beyond bolt ons.

I don't think the HKS unit will work with the Nissan ECU. The only way I can see it working would have you cutting the ecu harness and driving around with a MIL all the time. Both are bad, especially if you still have a warranty on your car.

The cams won't get rid of the limits, but you will reach them much sooner.:)

I understand completely about the rev limiter, but the only time the top speed limiter bothers me is on the race track.

Yeah I don't understand..when are you reaching over 100mph on a daily basis? While JWT is top of the line no doubt, I would recommend finishing some of your bolt ons, and buying some JWT s4 cams. Also, if you are looking for a cheap ass mod, buy a G20 ecu. These will plug into your car, raise the rev limit to 7500rpms, and remove the speed limiter. This is a cheap alternative, usually around $100, and you don't have to send jwt your ecu for a month or...three. Also, this way you will have your stock one just sitting around to send to JWT when you are going to make the plunge. Also..if you are looking for another cheap mod that will make your car noticeably faster, get a 1991-1992 se-r INTAKE cam. This boosted my cars hp around 8 with my intake and exhaust. The 91 cam will give you that boost in upper end come 5000 rpms. um...I'm assuming you have a Sentra SE-L or 200sx se-r right?

I think sr20 cams will work in a ga16 engine. Although now that I think about it, they probably won't. I haven't really looked over the ga16 like I have the sr20. I know pretty much everything that will and will not fit my se-r. I DO know that you can get an se-r throttle body though. Although this probably wouldn't help much, it is good for around 3-4 horsepower. Also, I know that you can get some underdrive pulleys from UR. I'm not sure if JWT makes cams for the ga16 though. Your best bet is that if you are actually serious about speed, just go ahead and spend like 500 on an sr20de and swap it into your car. This will probably cost you like $1500-$2000 total though. For a little more you can upgrade even more to an sr20det. You can advance your timing also. This is a cheap mod that helps many people. I'm probably forgetting stuff though, so anyone feel free to chime in. Oh yeah! Get an aluminum spoiler! I hear those are good for at least 10hp!! :D

Thats cool. Glad to hear JWT can mod your ga16. Sorry to tell you though, but your secret is out. Niss200sxgtr is hot on your tail looking for lights and aluminum spoilers! He has those indiglo needles too. Those add another 5, don't forget!!! :D

No SR20 cams will not work in a GA16...Yes JWT makes GA16DE Cams... You guys really need to take a look at Nissan Performance Mag more often... All the answers to these questions can be found there if you look through the issues. Just last month we did a whole story on the GA16 cams... Also read the Technical Section on Sentra.net...

Yes JWT has GA16 ECU's and NO a SR20 ECU will not work on a GA...

If you own a GA16 read Project 200SX...

With the new Hotshot Turbo kit for the GA, the SR20 swap is no longer your only choice...

But if he has nothing else to do it is none-the-less a start, right? I agree though, if you aren't getting a crazy amount of air in through the MAF already, then this will probably do you no good, same for the T/B.

If you are going to do NOS, do it right, with proper engine management, safeties, and two valves.

Doing it right will not be cheap. Anyone who says so probably didn't include the cost of a new motor in their total cost.

I would do the cams and ecu first. They're on all the time, the only thing you would need to refill would be the gas tank.:)

If you become a HP junkie, then skip the NOS and go straight to turbo.
