I want a JSRC but have some Q's about it. What do i need to upgrade for it to perform it's best? Should I build the motor first or just get a V-AFC, fuel injector, fuel rail, pulleys, cam gears, better clutch, axles, cv joints? any info would be nice. I already have I/H/E.

I did a search, not much there.

 

IMO, JRSC is

hah I know FI is better but i ain't a speed freak. I just want more low end. FI won't work well with ATTS.

 

uh, JRSC is considered FI....

 

all i have to say is TUNE,TUNE, TUNE !!

 

From my experience I'd say build up your fuel and ignition systems and as ELUD said TUNE TUNE TUNE! (also a J&S safeguard would probably help prevent your motor from blowing up). I would wait for the stock clutch to go before upgrading it.

 

There is a brand new JRSC for sale on Ebay as we speak. Great price.

in that case, i meant Turbo, Boost. thanx for the input fellaz.

 

Look into a hondata ECU they have great features and a boost option. I have heard that these go very well with any type of boost. http://www.hondata.com go there and read about them, they are worth the investment.

 

I hope you like engine rebuilds.

 

The only thing I can say is definitely get a hondata with bigger injectors. I ran 550's and had a custom pulley for 10 psi. the hondata willl work so much better then the JR crap they give you.

 

440 cc or 550 cc injectors
electronic engine management
J&S
Hondata IM gasket
plugs 1 step colder than stock
scrap the JR electronics and the JR FPR
Mugen thermostat
Mugen radiator cap
Mugen S2000 fan switch
redline water wetter
oil cooler
GOOD TUNING

haha

your talkin about supercharging right? hondata sounds good.

 

Ok someone humor me: What exactly is it about the JRSC that makes not all, but most peeps call it a piece of ****? I want to go FI, but I hear a lot more turbo horror stories than I have about the SC, so what gives?

To be honest, I really don't have the cash to do the turbo thing correctly (pistons, rods, sleeved, ic, bc, tt, manifold, piping, engine management, etc, etc) it just seems to add up to being a ton of money with the possibility remaining that my engine may still blow up. I don't want to do anything half-assed and then be unhappy either.

If the JRSC isn't worth a **** at all I'd really like to know, because damn I was planning on buying one in about 4-5 weeks. If it just isn't capable as it's offered, will the things that you guys suggested be able to make it a viable option or is it turbo or nothing? Thanks a lot in advance 'cause you'll be saving maybe quite a few of us from a $3-4K mistake.

 

Boosting is boosting.

The stock JRSC kit blows motors. THAT IS A FACT. It's a piece of ****, and if you want it to last at 6psi for a long time you have to spend just as much on a turbo setup for parts and tuning.

And once you up the boost too much you crack your ringlands on your pistons, and have to rebuild your motor. Welcome to boosting a prelude. Christ I have a sleeved block and I'm not even boosting it (yet).

 

eh. any type of FI can blow up motors. i know of turbos blowing motors at even less psi than 6. the jrsc is as reliable as you treat it, just like a turbo. meaning if you tune it right, avoid detonation, install it right, you'll be fine. of course, beating on your car all the time won't help if you have a turbo or jrsc.

most of the people with jrsc's that blow their motors are the ones that upgrade to 9psi without taking the proper measures to ensure the motor is capable of it, or they've added a bottle of nitrous to the whole thing. the odds of blowing up a motor with the jrsc is just the same as with any turbo setup. bad tuning = time for a new motor. that's all there is to it

 

So what I'm looking at is that there really is no quick, cheap, easy out. I'm going to have to spend the cash anyway, except that with the sc i'll be broke and slow...

Damn, that's not what I wanted to hear but I guess better to hear it now than $4k later. So, if you don't mind me asking, are you considering a turbo KIT down the road, or are you going the custom route? If a kit, which one? Thanks.

 

custom turbo, full standalone...block is already built some I'm gonna boost it all to hell....

 

holy ****, thats some crazy smotin info. i'd rather go turbo after readin all this but i got an SH so that ain't helpin. hmm how about nitrous? would the motor still blow? or can i just get like 50-75 shots? I would still need to build the motor correct? if so fidduck that. i'm savin my lude for fun driving and get a lighter car with a swap.

 

Basically no matter how you are applying power to the H22a SC/TC/Nitrous, the ringlands can only take so much stock....

Basically with GREAT tuning 10psi, maybe a 100 shot...

After that you have to resleeve, and build.

 

Here's my story, FWIW (not much).

I was sold on the JRSC awhile ago. The stories on prelude online made me think twice, and made me learn a lot more and do some more reading. My biggest problem with the kit seems to be the questionable fuel management (high pressures) and there is no way to aftercool the charger, or to add a water injection kit like there is on the civics. JR -certainly- doesn't guarantee against engine damage. The JR charger makes a lot of sense if that's all you need.. but if you need an injector set.. a vafc.. a J&S.. an ignition.. hondata.. then it's very expensive. JR also offers very little in the way of public information about who has had problems with their kit and why, and what the solutions are. There is much more turbo information out there in resouces like here.

Then there were all the little gotchas.. people having problems with electronics.. tip-in detonation problems.. mystery vibrations in the accellerator pedal.

Of course, some people had no problems at all.. but then again, some people have no problems at all on turbo with the prelude either. Either way, I now have to factor in the cost of a new engine, or an engine build into the process. With the JRSC, I am limited to 6psi regardless - 9psi TOPS, and that's assuming I'm willing to put up with no aftercooling. I have no way to change much other than that pulley. I have to throw away stuff I paid a lot of money for too - no way to customize the electronics, etc.

If I go turbo, then I get an intercooler, I can water inject, I have more ignition timing options, as I can go to a MSD unit right away, I can make sure I'm not cutting corners on the wastegate, if IATs are too high, I can do something about it, and I can easily adjust boost. When/if the motor goes, I still need to build - but now running 9, 10, 12 psi are all options. No boost control on the JRSC either.

Either way, I'm still going to need things like a wideband O2 sensor and a J&S or equivilant. Keep the money rolling!

My current plan is to go with the F-max setup once I have enough money for the kit and an engine build. Then I'll hope real hard the secondary injector setup doesn't go bad until I have money for a replacement ECU to run a proper injector setup. If it looks like I'm measurably losing compression on the 6psi setup, off it comes until I'm built.

In short, the JR offers very few benefits over a turbo and a lot of disadvantages the turbo doesn't have. I am reasonable sure a wideband tuned (I plan on an in car wideband) and carefully monitored 5-6psi turbo setup will run fine, especially considering that it's cold most of the time here (Eastern Canada).

Of course, nitrous is a lot more reliable than them all on the H22A. But it doesn't go PSSSSSSSH!

I hope that helps, a bit. The above is just my opinion, so take it for what it's worth (nothing).

 

"how about nitrous? would the motor still blow?"

There are a lot of positive experiences with a 55 dry NOS-brand shot on the stock H22A, and the 80hp direct port options on the stock block. Nitrous looks very reliable based on the PO.com data I last looked at. Just watch your plugs and if possible get it wideband tuned.

 

It doesn't matter if you have a SH or not. If you want to turbo then turbothe damn thing. Who said you can't turbo a SH?

 

You know i am sorry to say but reading all of this talk about how the JRSC is bad makes me sad... From what i have read so far on the JRSC it is an ok system and if it was maintained it could be better than a turbo in terms of reliability.

What pisses me off is that there are so many damn opinions out there and each time i read something good i get happy, yet each time i read somthing bad i feel my dreams being crushed. I have no damn idea what the hell to do now...I wanted to supercharge because i thought i would be less work than a turbo but it seems it jus about the same or maybe a little less. What should I do?

I want the reliability that supposedly come from a supercharger but is this true? I plan to fully tune and maintain the supercharger if i get one. Are they any more reliable than a turbo?

PLEASE HELP ME!!!

 

Trust me, I know the feeling. I had my heart set on one until I did some research and found out the ratio of those ecstatic with it to those that are currently doing rebuilds isn't good; heard everything from all 4 piston ringlands blown to a piston blown through the head. On PO.com they have a current thread on motors that blew up and those that are ok with JRSC and it seems to be running about 50/50. Half run fine on the crap they came with (fpr/ems) and others are upgraded and still blow the hell up, even at the stock 6 psi. Go figure.

If you belong to PO.com try this thread: http://www.preludeonline.com/showthr...threadid=26528. It has a lot of info about the JRSC. List of stuff they recommend if you want/expect/pray that it lasts stretches on and on; everything from AEM EMS to J&S Safeguard. Seems like it'll be just a big ol' moneypit like going turbo.

But i'm really hard-headed and I haven't sworn it off yet.
edit- typos
edit- Ok, I admit it, I don't know ****. Now, someone tell me what the hell a ringland is, and why they are the most fragile part of the engine on the H22? Would lowering the compression ratio possibly prevent this? Thanks for excusing my ignorance...
