I have a few questions do you like it 1/4 mile times do you know if it will fit with a B18C crx

 

i dont think it will fit

 

i'm sure it will fit, but it will require some modification. i did a B16 JRSC and that fit, so it probably wont be much different from what i did. check my sig for details. as far as quarter mile times, if you can get traction, you'll have good times. my problem was that there was too much torque when i was launching and as a result i would just spin through 1st and most of 2nd. that was on falkens though. if you're really into dragging you'll have slicks anyways and it shouldnt be a problem. i absolutely love it as a daily driver though

 

Thank you for your quick reply do you have a LSD I was hoping for low 13s high 12s on street tire what did you run with wheel spin in first and second have you tried to autocross is or would it be too much of a hand full are you running the stock pulley I was thinking of running a CRV pulley for 9-10 psi have you had any problems with th jrsc sorry for all the questions when I ask about the jrsc on other boards they say get a turbo so I am kind of excited to hear from someone with a similar swap

 

let me see if i can answer all of that. for future reference, please use periods, etc to make posts easier to read:

i do not have LSD, although it would be nice. the best i could pull was a 14.8 since the traction was so bad. i would bolt up slicks, however i dont feel like spending money and broken axles and trannies (to me its not worth a slip of paper in the end ). i don't autocross (except in my neighborhood ). i'm confident that it would make a great car for it though....i just dont have the motivation/interest to learn it/do it. i'm running the stock 6psi pulley for now, although my plans this spring is to intercool it with the LHT intercooler and at the same time up the boost to around 9 or 10 psi. i'll be using the MVM pulley instead of the CRV. i have had zero problems with the JRSC thus far, and its been on for almost a year now. as far as the turbo vs. supercharger debate goes, it all depends on what you want from the car (and what car it is). personally, i wouldnt recommend the JRSC for larger (heavier) cars such as newer civics/integras, simply because they require more power/torque to get them moving. however, in a CRX, i think it makes for an awsome setup. if you want a car where you can punch the gas at 3K and take off, then the JRSC is for you. if you want (a lot of) upgradability, then you should really consider a turbo. from everything i've heard and read, the JRSC has limits of 300hp, and realistically around 260hp with the right parts and tuning. i think this is more than enough for a daily driver. track car? many will argue otherwise.

 

Keebler, nice writeup I was lookin at it earlier today since I may start to save for a SC. LHT, gaw their crap is nice- $$ though.
Yeah, max power isn't what a SC is for. It's for more instant bigger feeling, broad power. I have on video (tape sorry) of a kinda local stripped crx running low-mid 13's w/ a JRSC setup also.
I guess that spacer's been working out for you? I'd rather just get the smaller pulley so I wouldn't have to make a spacer, but hmm, we'll see.

I to wouldn't care for a piece of paper that much if it costed breaking a tranny or axels. My car's a DD, so it's gotta be on the road.

 

yeah the spacer has been holding up great. the main reason why i went that route instead of a smaller pulley was because the small blower pullies tend to slip more easily. that leads to having to run the belt tighter, which i'm sure shortens the belt life as well as the bearings. when you have a smaller pulley diameter it basically means less surface area of belt contact. ideally one would have a CNC machined metal plate instead of the method i used, but either way will work.

 

I also have a JRSC on my rex,BUT It's on the original D series motor.Traction is a problem without an lsd tranny.Yet even all the spinning threw the gears I run a 15.1 with the D with the basic I/H/E mods.(needs tuning for sure)Anyway for a daily driver you can't beat the reliabilaty of a supercharger.

You make it sound like a turbo isn't reliable..

lets not turn this thread south, but for starters you dont have to worry about boost spikes or leaking oil lines. not that these are common, but they do happen.

 

jefsOng,I'm sorry but I didn't mean to diss the turbos.It's just everyone gets a wild hair once and the people turn up the boost to much then BOOM.Maybe they are just as reliable,but in my neck of the woods-seems to many motors get messed up.I know a supercharger is set at so much and I don't want to blow my motor by turning a switch/setting,lol-cause I would.

 

yeh, so would i...hmmm, lets turn it up just a ---- BOOM

I knew a guy that threw 3 out of 4 rods on his 96-00 civic sohc vtec. I was like 3! he was sprayin and boostin and doggin the poop out of it for a while though.

 

I did not want to start a argument about turbo vs supercharger. In my own well read opinion turbos can cause blown head gaskets and blown piston rings my car is a daily driver I don't have a spare car so for reliability reasons I have decided on the jrsc. I know turbos can be made reliable with good tuning but a good tuner in Oklahoma city is hard to find.


Keebler65 I like your website it is filled with good information. My engine was installed with a B16 motor mount kit to clear the stock hood so installation should be about the same. Also I dont think you make enough power to break axles if you use small slicks but I understand you wanting to play it safe. You said you had lots of wheelspin in first and second how is third. Is it crazy?

 

i know a guy with a eg b18c jrsc, he normally ran 13.7 on street tires till he blew his motor

 

You think a turbo would kill headgaskets and piston rings but a supercharger wouldnt?
They both do the same thing in the end and that is put more air in to motor.
Both are reliable and both arnt, NA can also be reliable or not it just depends on the idiot who built it.

 

Like I said I don't want this to become a turbo vs supercharger argument. But like I said I have never heard of anyone blowing their engine with the jrsc. But I have seen a car in the shop with a blown head gasket from a drag turbo kit, and have read countless people on honda boards complaining about messing up their engines with turbos. So you guys might as well quit now my mind is made up and you are not going to change it

 

your mind is made up, and thats fine.

but what you're trying to say is that superchargers are in some way *more* safe than a turbocharger. as said, they both do the EXACT same thing to the cylinders. compression is compression, be it with nitrous, turbo, supercharger, or high compression NA.

you also gotta look at the fact that no JRSC comes with any kind of air cooler = higher cylinder temps = more prone to detonation

I can't explain why more turbo cars blow engines it could be the way power is applied suddenly when the boost hits look at a dyno. When the turbo spools the power goes up very quickly. It could be that the sudden rise in cylinder pressure is what causes problems. Where in the jrsc it is always on and power is applied slowly. I don't know but its a thought and it makes sense if you think about it.

You are right the only thing is water injection or the LHT intercooler, but I have heard it is not worth $1000+. But I don't think I will need more than 10 psi the water injection will just be extra insurance and allow me to run additional timing.
