Hey guys,

I'm tempted to go ahead and try a JRSC on my daily driver GS-R and I'm looking for opinions from people here who have had them. I really do not want to have any significant loss of reliablity from the car and I have NO intentions on going more than ~200hp to the ground. I like the idea that there is no lag. (I HATE lag...) I've done a search and the JRSC sounds exactly like what I"m looking for with the exception that I've heard that it MAY experience detonation even in it's 6psi Jackson out of the box configuration. The last thing I want to deal with is detonation on an Integra... I've been fighting detonation for years on the RX-7 and I just don't want to deal with it. I would like to be able to run the JR kit with really no other modifications. (no hondata, no BTC, no map sensor mod, etc...) My question is this: Do I have to be concerned with detonation (will it happen) with the stock 6psi factory setup? The only current mods that I have are a short ram intake and high-flow cat. I do not want headers, I do not want an exhaust, I'm looking for forced induction without ANY additional mods beyond what is listed.

BTW- Please do not tell me to go turbo. I already have one of them on my RX-7 and I do NOT want one on my Integra.

 

pretty reliable from what I have know BUT. I'd suggest you do a compression check before doing so and checking the condition of your engine before hand because that also plays a big role.

But yeah I've heard it to be pretty reliable using stock boost depending on usage. If you are doing burnouts everyday and racing that thing all the time. I dont think your engine will last. But I would suggest to give it good maintenece on it before you run something like that.



thank you for not being noisy

 

I don't think my engine could be any better maintained honestly and I don't drive very hard at all. (NEVER burn outs, just occasional blasts to speed) I agree with the compression test especially since my car has 134k miles (I just need to go outside and do one). My oil consumption is under 1 quart every 5k miles and the engine runs flawlessly so I BELIEVE I'm OK.

 

Then I think your good to go! Also remeber to use synthetic. Best way to go on FI on tegs

 

Been running Amsoil 10w-30 for the last 30k miles or so

Have you ever heard about detonation with the kit though?

 

You *could* just bolt the kit on and go, but its primitive.

5:1FMU, 8deg timing, high intake temps...it isnt the best way to boost if you ask me. I would say by bolting on the kit and going, youd be lucky to hit 200whp. Ive seen 220whp and Ive seen 180whp, it really all depends. Either way you look at it, it isnt the most efficient way to do it.

If I wanted the most simple bolt on solution, I would go with a Greddy kit w/FMIC. Cooler intake temps, no lag, more power, easier to install....simple solution. The RX7 and Integra are 2 different animals man, totally different, turbo NA or SC. You can go JRSC if you want, and its a decent kit, but without at least Hondata, IMO, it just isnt worth it.

 

Hmm... Thanks for the input newgsrdriver. Compression tests yeilded ~229, 230, 230, 225... so I think the motor's ok

You say it's "not the best way to boost" which I would agree with but am I likely to detonate with it in stock form? Also how much are Greedy turbo kits going for? I'm not looking to spend a ton of money on the old daily driver. Basically I was thinking that I if I could bolt it on, make easy reliable horsepower with a slight increase in maintenance, then that would be cool. But if I NEED to buy a fairly large amount of other stuff to make it safe then I'm probably not interested in the hastle.

 

Bump for more info?

 

I would say detonation is likely in stock form, just bolting the kit on. Especially if you try and go too high on the timing...JR recommends 10 for 93+ Octane and 8BTDC for 91 if I remember right. I experienced detonation when first bolting on the kit and boosting away.

You can find used Greddy kits for under $2k w/IC...they arent *too* popular anymore, since people are more akin to going with a larger turbo for more top end, but for those looking for a simple bolt-on solution and an easy upgrade, there really isnt anything comprable. Its disgusting how well designed the Greddy kit is, really, when compared to piecing together your own kit or even installing a more extensive kit like Drag.

To be honest, I have been under my hood less with the turbo than with the JRSC. In terms of bolt-on solutions with minimal hassle, it really comes down to the Greddy kit and the JRSC. It all depends on which you prefer, a supercharger, or a turbocharger really...I would have to say the Greddy kit is the way to go. Mainly because along with the advantages of a turbocharger over an SC, you also get a bit better fuel management, and an intercooler, as well as an easier install IMO.

 

Hmm... yeah I was afraid that detonation might be an issue. I like the idea of instant power. I did notice that Greddy doesn't mention list their turbo kit for the 94 and 95 Integras. Is this because the emissions crap is different and the kit isn't designed to work with the older stuff?

The real reason I'm prompted to look into this a bit more now, is that I've always thought the JRSC seemed like a good idea and there is currently someone here in the Altanta area selling one so I'm tempted to jump on it. (when buying used, I would prefer to inspect things before buying) IMHO I think the problem here is that I don't have any personal experience JRSC or a turbo'd Integra, and I'm not very comfortable unless I'm 100% sure what I'm getting myself into. If I PLAN to do Hondata then that's cool, but I don't want to slap a kit on and then realize I need $1000 worth of extra stuff.

The other big issue is weather it's smart to install $2000 - $3000 worth of aftermarket stuff on a car that's not worth all that much money to begin with. (My car is a salvage car, though you'd never know it by looking at it or driving it)

All of this was just so much easier when moddifying my RX-7....

 

i have a 98gsr with the jrsc. i'm boosting 10lbs and dont really have any detonation problems. if you're worried it then the best bet would be to get the jrsc btc. if you don't beat on your car then you'll be ok.

what i've noticed is that turbos are for the track and sc is for the street. hehe...just my opion

 

Both turbos and SC's are for the street...the only difference is, the right turbocharger setup will make more power at the same PSI almost throughout the entire powerband.

To combat detonation and cover the inefficiencies of the kit, JR tries to sell you all these bullshit bandaids like water injection, btc, map mod, etc. It all adds up to too much money. Hell, Hondata is like $100 more than JUST the BTC.

Don't get me wrong, they can be great kits, I loved mine when I had it, other than the stupid belts. I just dont think its the "bolton" solution that its sold as. If you want it to make the most power and run reliably, you have to ditch the FMU and run an EMS, or a whole hell of a lot of bandaids.

Either of these kits will turn your daily driver into an all out blast to roll around in. I think the Greddy kit, out of the box, is more complete and more of a bolton solution. Definitely smart to install this stuff if you want to have fun with your daily driver...the only thing you have to worry about is the added attention increasing the chance of it being stolen, which is a huge huge problem with these cars.

 

newgsrdriver - What do you think of the Greddy kit WITHOUT the IC? I know there are no real downsides to an IC... but I am concerned about the "bling bling" factor of having a hugh FMIC in the car. Also I've noticed you can get a lot of the JR bandaids fairly cheap used. What do you consider the minimum JR bandaids to keep the system safe @ 6-7psi?

I really appreciate all of your input.

 

Unintercooled Greddy kit isnt too bad, although I would just paint the intercooler black, or maybe run a sidemount if youre real concerned.

Minimum bandaids? Hondata IMO. I really think there is no point in running a JRSC without it. You would need an AFC for basic fuel and vtec control (200+ used), the map mod for smooth transition into boost (75+ used), and a BTC to at least have some sort of ignition control under boost rather than just retarding the distributor (200+ used). Youre already at the cost of Hondata without the control.

For the most BASIC minimum setup @ 6PSI...no bandaids are necessary for some, all for others. I ran without any bandaids for a while...like I said, detonation was apparent sometimes, but it overall still was a fun daily driver. Until I got Hondata, and I realized what I was missing.

 

Ok, well that's cool. I think I'm gonna hold off on all FI for now.... I'm just having a really hard time justifying the funds to do it right on my old daily driver. (either JRSC or Turbo) I really appreciate everyone's input on this.

 

No sweat dude, thats what we're here for

 

Just FYI- I have had a blown LS and a blown GSR, both by JRSC. The LS was awesome, so reliable, torquey, just not too fast. The GSR had a chattering issue, which was unresolved when the car was sold a year later after pulling the blower 4 times and sending it to Moss once. ( They didnt do dick to the blower, horrible customer service ) It made about 200whp on 8 psi with all your bolt ons.

Basically, get it installed correctly, tune it correctly, and youll be ok. If it starts to chatter, bend over and kiss your *** goodbye.

Thanks for the input.... some of your old posts helped to make my mind up (Not that everyone has issues or that it can't be done right, just I don't want to mess with it for now)

Thanks for the link, but I had actually already reviewed the past year's worth of posts on that board prior to deciding
