Ok, all good points.

Tom, that 5 psi setup might be a good idea but another problem I might have would be getting the car inspected and passing emmisions. If I cannot, Id have to take all the stuf off and I would have wasted $ in the end, or I could just take it off every year for inspection
The JDM H22 would be the most reliable and least work required I think, but I might not be happy with the HP increase and swapping the H22 transmission could lead to me being unhappy. Does anyone know what the rpm at 80 mph in 5th gear is for an H22 Tranny?

I think that the ideal idea for me right now either be for me be to:

1. Keep the H23, turbo it with a small bolt on junkyard setup, keep the Tranny. Not too costly I would guess.

2. Ditch the H23, get a USDM H22 somewhere in a junkyard or from a member (hint hint) drop it in with the tranny and rock my socks all day long with upgrades from a type S later on.

I have heard that the H22 with H23 tranny is a bad idea. Can't land VTEC I keep hearing. In anycase, I don't think that turbo or N20 or a supercharger is unreliable per say, just that I would want it to be built correctly.

Building the H23 would be nice though, but no VTEC. Not that I need it, jsut kind of a frivilous want.

4,000 Rpms

 

Ok, if at 4000 rpm, you are going 80 with a H22 tranny, whats the difference with the H23, because my speen and rpm match. Is it just 1 and 2 that are shorter?

 

1st and 5th are the same....

yep 4,000 rpm, i think we could take a turbo kit off for inspection IF you fail. i can show you what my stock lude did in the emmisions test. I was WAY below their limts, so i think a lude with 5 psi , all set

 

Pertinent only if you go the H22 route:

I had a h22 with M2S4 (H23) tranny. I never had any problems with landing in VTEC. But I also had a laptop and Hondata and set the VTEC engagement at 4500rpm for the track and bump it for 5000rpm on the street so I didn't hit VTEC just cruising the streets. On my stock H22 4500 is about where the power curves of the low rpm cam lobes and the high rpm cam lobes intersect. I programed it at that intersection for a smooth VTEC engagement.

The Point: If you are going to go with an EMS (Which I would deffinately recomend for boost) then it won't matter if you have the H23 tranny. Like you said you are not expecting the track star right? So the gearing is not that much of an issue and the VTEC engagement rpm can be set to whatever you want. my $.02.

You do have a point pirate. Ill think about this.

I have a H23 and at 80 the tach reads flat on 4,000. I want V-Tech with my rev. limiter extended a few grand.

V-Tech Yo! tHaT **** is PhAt. .............. um variable valve timing and lift elctronic controle (VTEC) i don't see an H in there?

damn it adam, make up your mind, hehe, boost or cams and pistons, i think another question to ask is if you get cams and pistons can you expect reasonable gains WITHOUT tuning. obviously with every mod added ideally you should retune, but can gain be notice untuned?

 

Tuning can be done. I have no problem taking a trip or two to a dyno even though I have no idea where they are.
Now, if I go boost, can I still get cams and pistons that cater to the turbo...i.e. lower compression? I would have to resleve if I want higher psi, I know that. Maybe stroner rods as well.
In the inspection test, do they have visual tests that can determine that a turbo should not be there and then fail you without ever testing with the sensor in the tailpipe?

On another note, I was at a junkyard today and after looking for an hour, I found a 92 prelude SI. I needed the wiper arm off the car, so I grabbed it, and come to find out, that it does not fit at all. Chalk it up to another difference in years with the 4th gen.

 

well if your gonna go boost i would stay very low psi and and then that way you don't have to worry to much about the pisotns and rods

but when i wasy saying you could go n/a and get pistons and cams, i ment that you could get some type s pistons which are FRM compatable and then some cams. the raised compression of the type s pistons and more agressive cams should yeild some decent power gains. then you could get a CAI and even a header. but now you getting into bolt ons and the $ adds up fast. thats why in my opinion a bugget junkyard turbo setup would work nicely.

and check out http://www.slhondaparts.com, and compare the part numbers and pictures, and see if your sure they are different

 

If you did decide to boost the H23 and wanted to run more than 5 psi, you could run the intercooler piping like it is in the WRX sti with it going over the engine instead of in front.

I would like to hear the logic in doing this also!

 

A good reason to do that would be to keep the car a sleeper. I go to school in a high theft area, and having a turbo on a rare prelude is jsut that much more likely to get stolen like my previous integra.
Tom, I realive that I could go N/A and the cost would add up. Also, I know that the junk yard setup would yeild good results for cheap money.
Once again my goals are:
1. sleeper, nothing that says "hey, steal me".
2. Power with reliability
3. Money is not an issue as much as reliability is
4. HAS to pass inspection.

With this still in mind, I think that I might do the junkyard setup that prelittlelude has suggested. Reason being that is is reliable, ebcause 5psi is nothing to high where a honda engine can not handle. Also, it saves me on doing a complete engine swap and I can keep my transmission. Also, I am fairly positive that I can pass the emmisions test.
I would however like others' responses with turbo setups. Have any of you passed inspection, and if so, did they do a visual test and not care or say something?

 

do they even do visual tests, or is it all smog?? yeah boost is a great iadea adam.

 

Lets boost the ******. Settled. If I blow the motor, which I doubt, I can just easily replace it with an H22 or jsut build a better h23 if I dont blow a hole in the block.

 

Im in the same prediciment...

How many miles does ur car have? that might be somethign to consider. I do not feel comfortable with putting a turbo into my car with 117k.
I was planning on doing an h22 swap. ( fooling the man at the insurance company ha!)

then i wont have to worry about my car for a very ver long time! because it will have a brand new engine.

The h22 will be a good platform to start from.
This idea of the junkyard setup sounds good. would i be able to put it on my h23.. then say... conme the summer drop the engine and reinstall it?

 

This is my exact problem. My engine surrently has about 94k on it, but I am confident in its ability to hold together. If not, I can replace and rebuild like I would have anyway unless I crack the block or head, or other perminent damage. I could get an H22, which is a good platform to start with. Although if I wanted to stay boosted, Id rebuild the H23, becasue its a better platform for boost...or atleast better than the h22.

 

boost it bost it boost it
