I'll be annoying and start another one of these fun topics. A similar topic was archived but never finished.. and im curious on what you guys think about this. I uninstalled my JRSC about 3 monthes ago b/c I decided to get into the turbo game. But recently I've begun to reconsider. My goal is around 300whp and a good amt of torque to back that up (relative to a b16 that is).

Now, think this through with me. My JRSC is in mint condition, I bought it from a friend for $1400 and have never switched pulleys or nothin. Its only been run for 5 monthes or so and I have it all cleaned up for sale. But instead of all that, I am considering slappin on the 8.5lb endyne pulley and adding a dry 35 shot for like another $400 or so (used bottle if I can find it). With tuning, that should get me close to the 300whp range I would think. My math:

JRSC w/ endyne (215whp) + Nitrous (35x2=70whp) + Hondata Tuning = 285whp

For those of you that don't get the nitrous math, by dramatically cooling intake temperitures, it pretty much doubles your gains. I don't think its exact or anything but it gives us a good idea. Without even considering tuning, that would cost around $2000 in total (and I already have the JRSC so it would only cost me the bottle and the gas, but thats just me).

ANYWAY.. this is really starting to seem like a much more cost effective route to go with then the turbocharger. I don't think that I am gonna be craving much more hp then that but if I decide that I really want that, I can always switch to a direct port setup and up the shot.

What are your thoughts on this? Im curious because I dont hear about this setup very often. I know alot of you are hesitant about adding nitrous to your engines but this will be tuned and built, so Im not planning on blowing it up. Let me know what you think, I wanna have a good dicussion on this so please back up your answers and keep an open mind.

**EDIT: This was originally posted in the EG+ forum which is why some of the basic FI stuff is kinda spelled out.. sorry if it sounds like im trying to break it down too much for you guys.

I gotta state the obvious for a sec, but it helps me think.
Assuming you could also sell the JRSC for around $1400, plus the price of the NO2 setup ($400+) that makes your initial investment roughly $1800. Also, you have to fill the bottle on a regular basis... And another also; you may end up spending closer to $550 or so on that NO2 setup. So let's round up to $2000. Rounding *up* is always a good idea on an FI honda.

IMO and all that...
For $2000 I think you could build a very reliable custom turbo setup and be close to the 300 whp mark ALL the time. Especially since you already have a hondata. And I mention reliability because with NO2 and a JRSC, you've got 2 FI systems to worry about there instead of one, so the possibility for problems is substantially increased. Last but not least, there's the added benefit of the neat noises and whooshing sounds that turbos create... Either way, you'll have fun. Good luck.

 

I've done that math with the turbo setup and unless I do a junkyard setup (which im reluctant to do), Im gonna have a hard time finding parts for that cheap. The other thing is that the electronics for a JRSC are a lot simpler. The hondata would just need to be tuned once and it wouldnt matter that I had 2 FI systems.. I dont know, I'm pretty sure the turbo setup would set me back $1000 more then the JRSC.

 

Im going with this set up down the road. Right now i just built and am running the endyn 11lb pulley. Once i sleeve it is when the bottle goes on. It a very practical set up id say go for it. 11lbs plus the bottle is going to be nasty, I can wait though.

Edit: with the hondata you can just burn 2 roms, one off the bottle, and one on the bottle. Im guessing you are only going to spray at the track correct?

i am still waiting to see more people try the JRSC + NAWS setup and waht kinda results they get. plus i'd like to see a better fuel management solution for this setup. i'd have to say go with AEM EMS for nitrous control and fuel management with 440/550cc injectors.

 

Nice setup. How much did that set u back? Sorry if I didnt make it clear but I know about the two fuel curves w/ hondata (im in the process of becoming a quasi-certified hondata tuner myself).. and the nitrous will be run mostly at the track.

what it sounds to me that your trying to do is build a JRSCed car to be that of what a good turbo already is, if i was you dawg, id sell all my JR equiptment and buy a used turbo system or buid your own. if you build your own you could get a turbo system for about 1200. a used one for 2000+ and a new one for 3000+. drag systems have a lot to offer. you can get about 270whp at 9psi with a b16 engine on stock internals.

 

 

Check out the "forced induction integra" forum at hostboard.com. There are lots of threads on this type of set up. Good luck and let us know how it turns out.

 

I think you've got a great idea as far as nitrous and jrsc's.
It's the same setup that I'm building for right now, except I'm going with 9psi, and a 50 shot to achieve the 300whp (and probably more).

As for the hostboard site, it's really lost what made it such a good forum. The people are pissy now (like the H-T ITR forum), and there is nothing new being posted anymore. Imho, H-T FI forum is the next "jrsc central", especially when some of us jrsc guys start to post our dyno plots, 1/4 mile times, and placement in the local autoX's. That should be enough to shut the "turbo mafia" up

 

Thanks for the support. I will be weighing the two possibilities out until I get home this summer and can really start doing the work. I'm thinking about just skipping the dry shot setup and going straight to direct port injection. This might sound like a funny question but will it have the same kind of cooling effects as a dry setup would have? or will it just be like adding a regular shot of nitrous on any other engine?

My Friend has a 2001 GSR with JRSC+naws and he runs mid 12's with naws. Stock internalls.

 

Hell yes.

 

Hell NO! A JRSC will never put out the numbers of what a 10sec turbo cahrged car will.........unless it's a hell of a supercharger.

 

if i had to decide right now between a turbo kit and a supercharger kit i would most likely go with the supercharger for the simplicity, reliability, and price.

i think someone should try to do a custom supercharger kit that pushes 20+psi on a built motor, that would be sick

 

What??? Nobody is talking about a 10 sec car. Always has to go to the extreme just to show tuRbO's make made PoWeR y0!

 

Umm, what are you doing? Who said anything about a 10 second car?

Can someone help me out there? Thanks.

 

 

Ok if you are not talking about a 10sec car. Still a supercharger would never make as much power as a turbo charged car. If you had the same car with the exact same set up pushing the same amount of boost. The supercharger would pull from the line, but would have no match with the turbo. Here's evidence form his experience www.hybridgarage.com/tech/marc-jrsc.html

mainly at the bottom he states what my point is.

 

But for most people, 300whp is pretty much a large amount of power to be pushing on the street. "Shutting them up" is in reference to posting a 275-300whp JRSC'd plot, which would put it in the same realm as a nice turbo setup with instant boost and flat torque, something "even the turbomafia" would look at and go "very nice!" Thats all. Not saying which is better.

I think you shouldnt worry about it too much, the guys who know what JRSC's are designed for may poke fun at it, but they know its good for what it does. The guys who just spit "toibo is betta!", well, theres no help for them

About the dry shot/DP...why go DP if a dry shot can accomplish what youre looking for? It would just be more expensive and complicated, IMO.

 

some of us don't want to hit 10's.
Do you have any idea what it's like to daily drive a 10 second FWD car?!? or even an 11 second FWD car?!?

How about running high 12's on slicks, low 13's on streets, and 11's on slicks with the juice?
All with CARB stickers, and the ability to pass a sniffer test. Not to mention I won't be spooling at 4000rpm. I can still autoX the car, and I could even let my wife and baby girl take it out for a drive without fear of her crashing it when full spool occurs.

Don't knock the jrsc until you've driven in a car built by someone who knows twin screw blowers. If you ever come down to Vancouver, I'll be glad to take you for a blast.

 

The direct port will not have the same cooling effects as if you were to run the nitrous nozzle at the base of your intake tube. From what I've learned, you want to have as much time as possible to cool the intake charge by injecting the nitrous where the air comes in.

Because I can't run boost, and nitrous off my hondata, I'll be running a wet system. As per some of the guys at Magnusson, the screws can handle having both nitrous, and fuel flowing over them. Also, injecting earlier in the tube gives the nitrous a chance to cool the supercharger manifold, and blower itself.

 

I'm actually not knocking the JRSC, just i perfer turbo over it. It all depends i say on the type of hp and torque your looking for. I'mm looking for big torque, that's why i chose turbo. I almost bought 1 but i didn't like the horsepower numbers. in texas we don't have to worry about all that extra smog crap and depending on where you live all the check is your blinkers and brakes . I just prefer turbo over JRSC, but i know there fast as hell when n2o is added.

 

Im curious, please edumucate me somebahdy

With Hondata, how would running a small shot work in terms of tuning? If youre already tuned and you plan on tossing a small shot on, wouldnt that complicate things once the nitrous is injected? Like you say, we cant control both...why would a wet system be beneficial with Hondata as opposed to dry?

 

I don't believe Hondata does that set up for nitrous yet. I know AEM EMS does though.
