I'm new to forced induction and am planning on buying a JRSC. I plan on putting it on a stock motor with a few bolt ons. (I/H/E/test pipe) I'm looking to add a sc to get some more horse power BUT i want to retain reliability. can anyone guide me to how i can do this? I will be boosting the stock 6 psi.

My car is hitting 85k miles soon, and i plan on doing the 90k tune up. Should I do the tune-up before I slap on the sc? or does it even matter? I was also planning on doing an auto to manual tensioner swap.

I think thats about it, i've been reading a few posts from other people with sc and say they're car ran hot, would it be adaquate coolign without an intercooler?

 

i would suggest the tune up first before slapping the s/c, while your doing that you should have the s/c rebuilt knowing for the fact you cannot buy them brand new anymore (discontinued). It would be more of a hassle to work around the s/c on your tune up, removing the parts could be somewhat be difficult for some people. I would also suggest running a tunable ecu, p28, p72 w/ hondata etc, also upgrading the injectors as well. You might lose your ability to smog proof the car, but you will have more reliability over the JRSC ECM. Goodluck let me know if you have anymore question. Since i'm currently running 9lbs on my prelude for over 5+ years.

 

dam 5+ years..thats the reliability I want. I plan on just boosting the stock 6 psi. Just want a little more power. What parts exactly would you recommend changing on the sc? I was already planning on replacing the belt, i heard you should replace the belt every 10k miles.(corret me if i'm wrong)

There's no way to tune the stock ecu to be reliable? How large of injectors should i get?

 

I agree with ludboi121 about doing your tuneup first. You have to disassemble a lot of factory parts anyways, for the charger assembly, so you might as well do your tune up while you have everything out.

As for the temperatures getting hot, so far as I can tell nobody makes an aftercooler for the JRSC on the Prelude (I've looked high and low for one). It would definitely be a custom job and some serious cash to get one on...however, I'm assuming with the space being so tight near the firewall, there's no room for one (probably why LHT never made one). Like ludeboi said, you could rebuild the charger and safely run some nitrous to help with that (but maybe not wise on a bone stock motor...)

Sorry to post ***** here, but what kind of power are you getting with the 9 psi ludeboi? I'm in the process of wrapping up my JRSC build (just gotta drop the 550s in and bolt the charger back up) and I went ahead and installed the 9psi upgrade too. I haven't had a chance to see the car running with the charger yet, but I'm curious to see what type of power you're getting outta yours...hopefully this will be good info for the OP too...

 

The sc has about 7k miles on it. Can you provide me with a list of parts I should replace on it? Also, for a build thats boosting 6 psi, what can i do to achieve maximum reliability?

 

Well, IMO 7k miles isn't anything to worry about, since if you bought it new JR has a 100k mile warranty of them....and since you're only boosting 6psi, it's not necessary. If you want some literature on what rebuilding the charger consists of, read here http://www.theoldone.com/artic....html It's a little long, but they give a good bit of info on the process and how it works. It'll run you ~$1500 to get it done. Like I said though, shouldn't worry if you're only pushing 6psi. That rebuild is meant for boosting 12psi or more, which takes some work...

As far as reliability, like ludeboi said, you'll need a tunable ECU (the stock 5th gen ECUs are not compatible)...there's a lot of literature on this in the FAQs at the top of the forum pages.

The only things I double-checked (I bought mine used too) aside from the charger unit are the belt-drive pulleys and idler pulleys to make sure the bearings were good and they spun well with no stick to them. A few of mine did and I ended up buying a couple bearings locally for $5 each. You also want to make sure your jackshaft assembly is smooth too (again, mine wasn't, ha--it would stick every 10 turns or so) so I ended up getting a new shaft and pulley for it, fixed the problem easy. I think that's it, as far I remember off the top of my head. Hope that helps some.

 

i'm most likely have check out the belt and pulleys. Would boosting 6 psi on a stock motor without tuning be reliable for daily drive and maybe once every other week vtec?

Any idea how much a tunable ecu + tuning would run me and how much more reliability I can gain from this?

 

tunable ECU = 400-1000+ (hondata S200b will get the job done, but hondata has made the move to only support the S300 now i believe. and the AEMES is available as well)

tuners tune at different labor rates and tunes will differ in time needed. dunno about the tuning on a JRSC, but the previous owner of my car paid 6-7hours of labor to get my car to where its at, and its still on a base tune. thats at over 100$ an hour. so through and through ur looking at the JRSC kit cost + tunable ECU + 100anhour + misc. parts that will rack up. bigger injectors, fuel system upgrades, colder spark plugs, etc. etc.
