This section is the Shiznit. I have been on many different boards but this site and this forum are great. The moderators are a great help.
I have just finished swaping a JDM engine into my 5th gen and JRSC and this site its members and moderators have helped greatly. for this you all deserve a big pat on the back.
Thank you everyone for your help, your a great bunch of Ludders that really know there stuff.I am proud to be a member.
I agree this FI board rules!So much information its hard to take it all in.Fast responses,the mods are great, everyone helps each other out and everyone learns from each others mistakes.
charged,
tell me again why you are supercharging a jdm h22? I was under the impression that the jdm motors run a higher compression...which is not FI friendly.
I get that question alot but its all good, Jackson Racing loves the idea and just sponsored the car .They said there will be no real difference they have done it before and yielded more torque than the US spec stronger internalsaswell.

that's what i suspected....i guess the internals are stronger for sure, but if it's a 97+ jdm H22 aka type-s motor...there is more overlap and the compression is 10.5:1.....so unless you dial down the cams and get a thicker head gasket, the JRSC is not going to give you the power you want due to blowby and there is a greater risk for detonation. I dunno if the folks at jackson racing have their heads screwed on right....
10.6:1 i belive!
Jackson said its fine they sell JRSC kits for those motors in Japan often. its a 92-96 motor it had 46,000 kilometers on it,so shes rather fresh and it was auto bonus for me no high revs have been put to it until now!

well, i don't care how tough the jdm motor is...running at 10.6:1 compression with no intake charge air cooling means that you are going to have to back off on the timing, and will bog the car in terms of performance. No offense, but for someone who got sponsored to build up a prelude, you don't know that much about preludes in terms of performance upgrades. I guess jackson is just trying to sell the look and not the actual function.
Really ! Interesting I guess you havnt read much because both Zex and JR are working with the car.N2O cooling...????
Plus I would say Moss Motorsports has better R&D than you do but hey thanks for the smack talk anyway.
Theres one on every board I guess.

Nitrous cooling the intake charge air would have to be wet and no more than a 50-75 shot, and that might help with the detonation but why start out with a primarily aggressive NA motor like the jdm H22 that has higher overlap and compression...both of which doesn't work well with FI. I haven't heard you address any of these issues..is nitrous supposed to help with the blowby? If your sponsors have so much cash to spend, why not build up the motor, then blow it?? I'm not trying to get personal, i'm just a bit confused at the buildup. In the end, i suspect your car is purely for the showroom anyhow.
I think your thinking about a Type S. This motor yields the same cams as a US H22A4,This is a JDM H22A ,The only real difference is stronger pistons a tiny bit more compression. And its an OBD1,
If you do your reaseach you will find there are 4 different JDM VTEC H22A motors that were offered in Japan. We are in tuning and arent having any real issues. I think that JR ,Zex,Apexi,and Hary st.Mary are more knowledgable than you would be. they all see no issues and if you speak with Hondata they just finished working on this exact same set-up and said it yielded more Torque. You think there all lying or maybe do you think that you need to do some reasearch on the Prelude and its motors. there are Euro spec H22A's too! And as to your last comment ,Yes this is the most sucessful Prelude on the Canadian show circut last year. It won hardware at over 18 shows in 2001!!
In 1999 it was the CIDA (Canadian Import DragRacing Association) class champion, and overall points champion. with a best time of 14.56 it was NA.
After a year and a half off from the track the car is going back to its roots the 1320 with some FI and a whole new set up !
I wanted to have a multi purpose car , show ,go and the tunes.
For 2003 the car will be campained on the points chase again , this is a set up year for me.
You can have a show car street car that pulls low 13s .

charged,
your setup will work, i'm just harping that you won't get the real potential out of your setup but since you are not paying for it, i guess you can't complain. From the sponsorship point of view a jdm H22 might sound impressive....those pistons might be stronger, but you still have 'de-tune' the car to avoid detonation anyway, however, since this is a show car it doesn't really matter. The engine bay just has to look nice. I guess building up a motor for a JRSC setup that will only yield 9 pounds of boost is overkill. IMO, i would keep the compression at 10psi so i wouldn't have to dial down the timing so much since there is no such thing as boost lag in a supercharger. I agree tho, preludes aren't much good at the track, it's better as an overall ride....sound/style/street power.
I'm gettin a healthy dose of N20 in my little 3g pretty soon, along w/ a JDM motor. I don't wanna spend the money for a turbo, cuz I'm gonna sell the car I have pretty soon, and transfer to the SWEET,SWEET 5g, then I'm gonna go w/ a wicked turbo setup! Even better than TrboH22's!!
