I know i've searched, but things aren't clear for me.

Prelude Si H23a3 t3/t4 FMU,DSM,SAFc, Walbro blablabla
I want more power, but have to build my H23a3. Only problem is in my country we don't sleeve. So i want to run forged pistons and rods on the stock sleeves.In my country are no tuners that sleeve.How much psi can the stock sleeves take.

I know there's a difference in materials, so not every combo will work. What combo does work.
Do i have to coat them?? Which ones will fit?? From what i've read, wiseco with skirt design will fit. What rods would be best??

I want to run 12 psi maybe 15 psi ones in a while, what can i do without sleeving??

In my country i need to order everything from america, so i really need to order the right stuff.

ditch the fmu, ditch the safc
if you're gonna risk it running forged internals with stock sleeves,
you're gonna want a better engine management system,
EXPECIALLY if you wanna run 12-15 psi

 

That's the best i can do for now, i'm a student and bodybuilder and don;t have the funds for that right now, but i will soon. With the FMU and Safc i can still boost 12 psi and have a little bit of management. I also have MSD 6 al, MSD BTM, Blaster ss coil, MAgnecor 8.5. So i should come a long way right? I just want to bulletproof the engine for more boost later on in the project.

This is what i have right now, what's the best i can do with this setup?

I'm talkin forged pistons stock sleeves here.
Advice please no lectures about anything else

 

anyone?

 

good luck? lol

 

If you can't sleeve deep freezing it. It's supposed to extend life 150-500%. I've yet to hear if anyone has tried it yet but I've heard a lot about it. It's real cheap and could possibly be a cheap way to get a high boosted turbo and get around sleeving it.

Here's some advice then, if you're gonna use a shitty ems,
and you want it to last, dont boost over 6-7 psi or it's gonna cost
you bigtime

 

you can't run forged pistons in stock sleeves.

you can't reliably boost over 6-7 psi without excellent tuning and fuel management

end of story. Since you can't sleeve and don't want to get a full standalone you might as well stick to bodybuilding instead of engine building.

Looks like an option to me, i'll try to find out if any tuner over here does this, and see what the possibilities are. Thnks for the advice.

Okay cool, i'll try to stay within limits then, for a while I've been running 9 psi for 3 months now, still no ringland problems or any problems, I want to get rid of that scary feeling that things are gonna break when really stepping on it. Just so you know, there isn't even a hondata dealer over here, that's how crappy stuff is over here.

There's a guy on the board(dc98l something)running forged pistons on stock sleeves turbocharged for 25k miles now. So i wouldn't say can't. I have enough fuel management for 7 or even more psi right now. The story doesn't end for a long time, there are still options and i'm still trying to find out the best thing to do. I can't sleeve "over here'' Who said i don't want to get a standalone. i already have one, but it may not be known to you(it's a stinger stand alone) Not installing yet looking for a good base map. Engine building and bodybuilding go great together i can lift the block my self.......always handy. So i'll build two ways if you don't mind.

 

Hey the only alternative is that I would order new OEM pistons and send it out and get it cryo treated. Its about 70 dollars to get your pistons treated. http://www.percryo.com/ Shoot those guys an email they helped me out alot with my tranny work.

 

Okay cryo treated is possible here, but there still be that ringland problem right?

 

Im sure there still might be. Think of it this way.. You will have stronger pistons and connecting rods and less chance of blowing it up. If you get this done and proper tuning I think you will be ok. This is better alternative I see on closed deck design.

 

I have a h23a3 haven't opened her up yet, but i'm geussing it's closed deck(hoping). I'm gunna start making some calls next week. Thicker head gasket and Cryo treatment are now running trough my mind. Maybe install the Stinger standalone next week to and go to the Dyno and see what happens.

I've already emailed Wiseco to ask if they have an option for the forged pistons on stock sleeves idea.
Thanks for advice man i appreciate it

Any more tips are always welcome.

 

E mailed Wiseco last week, and got some response. I asked them about the Wiseco forged pistons on stock sleeves in a H23 block. and this is what they told me

The use of stock sleeves are no problem, nikasil coated or oncoated no problem, the ringlands are made for this. only problem is when sleeves are chroom plated, but this is very oldschool. (That's ruffly translated what he they said)

In their catalog they have pistons for the h22 and not the h23 he gonna let me know the part number so i can order.

Couple of questions, how much psi can i run with the wiseco pistons and stock sleeves with good management etc etc?? What rods go best with these pistons??
Do these rods come with new rod bearings??
