This topic is specifically targeted to owners of JRSC Preludes that would like to see an intercooler solution developed for the application. By now I am sure that many of you have heard the news of the LHT Performance air/water intercooler for the B-series JRSCs:

LHT is interested in attempting to design a similar system for the H22 JRSC. In order to perform the R&D, specimens of the JR blower adapter plate (sometimes referred to as the JR intake manifold), as well as the Prelude stock lower intake manifold need to be sent to LHT. Being that most, if not all of us, have these pieces already installed on our cars, it would be asking quite a bit for any one person to dismantle their setup and suffer the down time of their car. A few of us over at po.com came up with the idea of starting a pool involving Prelude JRSC owners interested in seeing this made to collect the money needed to purchase a spare JR adapter plate for the R&D. It retails at $291 direct from JR. We currently have raised $200, and we are contacting LHT to see if they can get the adapter plate at a wholesale price from JR to lower the cost. We figure that we can grab a stock lower manifold cheap out of a wrecking yard, and know someone that may in fact be interested in donating a spare lower manifold that they have.

If you are interested in participating in the pool, please contact me or ht.com member specialque via PM or email, and we will provide you with more information regarding the pool. We will also keep this thread updated on the amount of money in the pool.

Boosted97Lude, thank you for allowing this thread.

 

an intercooler would be a nice idea, in theory i suppose. but being that my car, my only car, is my daily driver, i can't afford to be without it for more than a day. and i'm not sure i want to be part of the "guinea pig" of all this. a lot of risks involved obviously. how long did it take JR to get the supercharger for the 5th gen prelude right? the first two years it was out, there were constant problems with leaks and ****. then in 99 i believe, they finally figured it out.

my questions is, would there be enough room in the already jampacked engine bay to route air from the blower through all the piping, through the intercooler, then through more piping and back into the intake?? there's barely enough room for just the blower and belt assembly. i don't know, where there' s a will - and funds - there's a way right? i'd like to see this as much as anyone else. just not seeing it right now.

how much exactly are you asking from us anyway?

 

No one wants to disassemble their setup and send their own parts in, which is the reason for the pool: to purchase the two pieces LHT needs to look at. This would not be a setup with plumbing diverting air from the blower and then back, it would be an intercooler core incorporated into the manifold. Check out the links I posted above, they explain what was done for the B-series setup and include pictures. There is no minimum contribution to the pool, you can contribute however much you like.

You are right, room is a serious concern with the Prelude JRSC setup. LHT believes they can incorporate the core without having to reposition the blower. They are familiar with the JRSC kit.

Just as an aside, I am not at all affiliated with LHT, I'm just a JRSC owner that got excited when I heard about the B-series setup and would like to see it done for us.

 

bumpity bump

 

bump cause i wish i had FI
sounds like a good idea.

 

That is VERY cool, I'd be so interested if only they made the kit for the 4th gen VTEC.

 

yeah, i actually took the time to go through those links. pretty cool stuff. definately sparked an interest. i may have to reconsider my prior decision to not to participate in this. we'll see though, i'm not fully convinced. but it's definately something worth looking into.

 

Bada bing, bada bang, bada bump. Big bada bump.

 

here's a bump since I donated..

 

Buh buh buh bump.

 

Bump.

 

shark,

i got a 97 lude and i am getting a JRSC, but i have heard the belts that come with it slip, so u mentioned u had use gator back belts, is there anyway i could get the part numbers for 'em. how is the lag off the line with the jrsc and the ss tranny? plus iff you got any advice on how to make sure my **** doesnt detonate thatd be appreciated

fellow ss luder,
GT Pete

blower belt: 5pk525 (Goodyear number 4050200)
main accessories belt: 6pk1930 (Goodyear number 4060760)
main acc belt with AEM alternator pulley: 6PK1970 (Goodyear number 4060775)
power steering belt: 4pk1065 (don't know Goodyear number offhand, not using Goodyear belt for this one)

And for the nay sayers who believe one or the other AEM pulleys will not work with the JRSC because their installer said so for whatever reason, here is a pic that proves they work just fine with the JRSC:

There are 3 things you can do.

1. Intall the kit as it is, take it to a dyno and have the fuel pressure and the BTC (boost timing controller) set, and hope it doesn't run too lean.
2. Keep the JR fuel pump and the JR electronics. Replace stock injectors with 370 cc injectors. Replace the JR FMU with a Cartech 2025 FMU (much more adjustable than the JR piece), and add a VAFC for fuel control. Get good tuning.
3. Dump the JR fuel pump, the JR electronics, the JR FMU. Run the stock fuel pump, stock fuel pressure. Get 550 cc injectors. Get EFI Systems PMS or Greddy Emanage. Those are the closest you will be able to get to standalone units since you have an auto. Get good tuning.

Eh, it's an auto, it lags off the line. Get it on the freeway, and it screams. I'm running 9 psi, by the way.

 

This is why LHT or someone needs to make an aftercooler solution for the H22 JRSC:

 

The pool now has just under $300. The goal of the pool is ~$400 (JR's shipping costs are ridiculously high).

 

I have a bare H22 intake manifold. I'll sell it real cheap.

 

JDM lude, how much you want for it?

 

bumb cause i want a this thing made

 

199 intake temps??? wtf i dont even get near that with turbo when its 100 degrees outside... btw i would not wanna do a timing belt on the mother ******

 

bump because we have a lower intake manifold now!

Not surprising since you have an intercooler.

 

Anything happen with this?!

 

Unfortunately, LHT has shown us little interest in attempting to design an intercooler setup for the lude JRSC. All the donated money is still being held, it hasn't gone anywhere. Anyone that would like their money back can PM me or specialque.
