93 si w/ H23A1...i'm wanting to supercharge...cant find one to save my life...jacksonracing.com has no answers...can it be done? how? and what do i need??? PLZ!!! i'm going carzy

 

You can supercharge a moped if you want. Doesn't mean you should or that it's wallet-friendly. Currenty there is not a supercharger designed for the H23. It's been said that there isn't enough clearance. Swap in the H22 if you want a JRSC.

 

supercharging any 4th gen is pretty close impossible because of the clearence with the firewall. PPL have dont it, but it is usually on a RHD lude because their is more clearance on the side. For the sake of frustration look at turbo or NA... lol

 

It can be done with a Jackson supercharger. One of my customers has an H23 swapped into a civic hatch with the JR supercharger. At the moment it is running in the 12's

 

i thought superchargers replaced intake manifolds? thats what i've read so far...correct me if i'm wrong

 

As I think about it, doesnt the JR kit just replace the top half of the intake manifold? So in theory an H22 JRSC would work on an H23, just gotta see if the brackets and all line up ok. Then you have the added issues of the 4th gen chassis, and the limited potential of the SC compared to turbo.

Clearance is the problem, not fitment.

so what would be the H22 difference

swapping for an h22 wont make a difference, ITS THE BB4 that wont fit it!

 

It is possible to supercharge the 4th gen, there is a slight firewall issue, and also the shock tower, both of which can be remedied. If it can work in a civic, I'm positive it can be done in the 4th gen.

Having just installed a JRSC on my 5th gen, and I'm sure those of you who also have it can agree, even if you were somehow able to magically wedge a S/C into a BB4 with an H22, you would have a HECK of a time doing any regular maintenance to it, etc. I mean, it's already a tight enough fit on a 5th gen that if you are a big-handed mechanic, you're going to need a skinny side kick to reach things for you, lol. Also, removing the thing would be that much harder if you ever needed to pull it off. I just had an injector go bad and there's no way to remove an injector without taking the entire kit off, save the pulley system that runs to the crankshaft...Just saying, if it's that hard to wedge it into a 4th gen, just imagine taking it back out if you needed to...

 

I remember someone on here that had a JRSC in a 4th gen. I don't
remember all of the specifics but they definately had to make a custom
bracket to solve the clearence issues.

You need to be much more specific when you make statements like that. Jackson Racing NEVER made a supercharger kit for the nonVTEC H23. If your customer has a JRSCed H23A1 then something's been done either to the manifold or the head for the H22 JRSC to fit the head.

If you mean your customer had a JRSCed JDM H23A VTEC that came out of an Accord SiR or Torneo then that's different and you need to be forthcoming on that info.

It was an H23A1, USDM, with an H22 JR supercharger. The charger replaces the top part of the manifold, which is the same as the H22.

 

I looked around a little and you're right. I must have gotten confused with the K20As with the integrated IM that I've been looking at for the last few years. I appologise and I'll remove my previous post.

 

So to answer your original question of "can it be done" the answer is yes, can it be done is almost always yes... it just depends no how deep your pockets go. IMO dollar for dollar swapping in a JDM H22 is the better route and if you want F/I go with a turbo on either H22 or H23. But asking questions like can it be done gets all the mental gears of honda enthusiasts working and you are gonna get some pretty creative answers lol

 

i want creative answers i have a very open mind...remember i am female and like i said i'm still learning...but i have another question...turbo kits are ALOT larger that an SC....to put a turbo i whould have to remove PS ans AC right???

 

yeah. they're both heatmonsters, now, where do you want a heatmonster smashed, in the front airdam, or directly smuldering on the intake manifold, with no fresh air UPON it...

 

I thought log style manifolds allow clearance to keep AC and PS

 

i'd use a log. drift wood fits better than the long bendy arm tube style ones.

 

That was funny!!

Ok in any case, I seem to remember that at one point in time, JR actually sold the kit for an H23 4th gen, because my buddy was looking at it for his car in oh 98.

Also to clarify what I said earlier, thats what I meant by the 4th gen chassis issue, that the clearances would be so tight, just like the H22 4th gen. I know at least 5-6 if not more people have made the jrsc work on 4th gen H22 cars. Some did it with custom brackets, some hammered the firewall and ran low topped shocks, or hammered the shock tower on the drivers side, but they made it work.

In the end, I look at what it can do, and for what cost. I know 2 cars, engines built by the same builder, tuned at the same shop, same amount of money put into them. One 4th gen H22 turbo makes 640 whp on 21 psi, 5th gen H22, JRSC with nitrous, on 18 PSI with custom pulleys and belts, makes 380 afaik. Heat soak limits the JRSC sooo much. This guy has the JRSC modded by Endyn, insane built motor, and nitrous plumbed direct shots into each runner on the bottom of the manifold runner for max cooling even!

 

I think the centrifugal supercharger would be better. Its smaller and would not need to replace the entire intake/throttlebody etc etc. Ones like a paxton I think you could retrofit pretty easily. Only problem is not too many centrifugal superchargers are for 2.2-2.3 litres. They are for larger displacement motors.
(rather than a roots type blower I believe they are called).

The thing is though honda's rev higher than the fords/domestic cars that paxton's are designed for too, soo some math would deffinitely be involved to find out the flow rate on a motor that rev's to close to 7000.

Im wondering how many people have retrofittedcustom fabbed centrifugal superchargers for preludes.
