As you can see from my other new post I just f@#ed up my engine. So I was thinking doing the type s conversion ie pistons, rings, cams. My question is can I run stock valves, springs, retainers and seals in the head. In the block too can I use stock rods, bearings, pins and not resleeve the block or anthing like that. Basically what will I need to do and use for a type s conversion. Thanks for the help.

Oh yeah what kind of gains would I expect with the conversion?

 

from what I hear (and read) it's better to upgrade your valves, springs, and retainers. Just with the cams you can expect somewhere between 5 and 10 WHP depending on what other mods you have.

Here's a site you may find interesting: Type S Cams install and analysis. I'm not sure if you need resleeving. You probably should read (or reread) the thread at the top of the Prelude form written by Lone Luder: A few things to think about when going NA...

Remember the biggest issue is going to be tuning..at a higher compression ratio (with the Type S pistons) you will have less room for error on the tuning.

 

thanks

 

found some type s stuff. Are these the correct part #s? So I dont get screwed.
Pistons:13030-p5p-j00
Rings:13021-p13-013
Pistons: 14111-p5p-j00
Thanks again one of those #s should be the cams but I dont know

 

14111-p5p-j00 is the camshaft

not sure if the other part numbers are right. Plug the part numbers you have into http://www.google.com and see if anything pops up

 

anyone know if and or what I can use that is stock for a type s conversion

 

bump

 

well, from what i understand, which isn't a lot, another thing you have to worry about with type-S pistons is which pistons your block requires. yeah, they're all H22 pistons, but every block uses 1 or 2 kinds of pistons, the A's and B's. They are almost identical but the A's are slightly bigger than the B's. If you take off your head and look at your pistons they'll have this A or B on them. Now, each H22 is different, in that there's no standard piston layout. mine could be all a's yours could be baba, kotetu's could be abbb. so, though you don't need to resleeve, you'll prob want to get all Size A type S pistons, and if your block happens to have some B piston cylinders, have a machine shop bore it to fit the A's. I have no idea why honda did this, can anyone who's in the know share what happened with this whole thing?

Also, i think you'll need to do something funky with the stock rods to attach the TS pistons. not quite sure what, but it's not a plug n play fit.

also you'll want a type S camshaft, or maybe a crower. if you were to go TS pistons, camshaft, depending on what else you've done, you might see upwards of about 15-20 hp (10:1 >>>11:1 = 6%(200) = 12hp; camshaft >>> 5-7 hp)

 

another option is to get the .25 over, and have them just re-hone all the cylinders and pop the "over-sized" pistons in.

 

hmmm

95 lude this may be a good option to consider becasue depending on what damage was casued when you F-ed your motor up you may need to hone all the cylinders, but you won't know what happens until you open the engine, if the ring landings let go your cylinder wall will be pretty bd, hope for the best

 

Ya, best bet is to find out what you have left before you go making any purchasing decisions. What you have left will dictate what you need and don't need.

Also, the Type-S piston compression is not going to be a good idea if your going to be shooting nitrous all the time.

 

This is probably all available by searching but I'm bored so here is what I know about using Type S pistons:

This is major surgery on the engine. Get or borrow a helm manual. Follow the instructions in it. Use new rings. The standard H22 rings from honda work great. If you use overisize pistons order oversize rings. Measure your bores and use the appropriate size pistons. Yes the blocks are marked with the bore sizes, but unless the engine is new there will be some wear, and there is little difference between the A and B pistons anyway. My suggestion: If you're going to go to all the work, do it right and get the oversize pistons and have the block rebored/honed. You don't have to sleeve the block for Type S pistons. They are cast and work fine with the FRM liners. The pre '97 H22 have a pressed wrist pin. You can have bushings installed in these rods to work with the floating pin on the Type S pistons. You may be able to use the pressed pin with type S pistons. Just measure everything and make sure the clearance and interference dimensions are correct. 97+ H22A4 engines already have floating pins, and you should be able to use the stock rods. If you want to use Eagle rods, get the ones with the right size for the pin. They make two sizes, get the smaller one. A few builders have told me not to take these pistons over 8500rpm on a regular basis. Several builders are also preparing the pistons by sanding off the cast letters on the piston tops and slightly enlarging the valve releifs. Here is an example of this:

Now that you've read all that, if you are cheap and really don't want to remove the block from the car, you can probably put in type S pistons without re-honing. You can probably even re-use the original rings if they are in good shape and you had good compression before you tore your perfectly good engine all to pieces. Keep them in the same positions and orientations if you do this, and make sure the cylinder walls are in good shape. I'm not saying this is the right way to do it, just that the universe will not implode if you go the cheap route. Don't come crying to me if you start burning a lot of oil though. Now have fun and let us know how it goes...

 

ah a definitive answer.

a H-T classic post. thanks flyrod.

 

Good advice, but don't go the cheap route if your gonna tear it all down. Do it all, do it right, and get the right parts. Bore/hone for the oversized pistons, get the Eagle rods, don't manufacture clips, not as strong, and get a valve train on top of all that to handle what you want.

Now, if your thinking about going the cheap route, why not just order a motor from hmotorsonline or some place like that, and just do a swap. Then you could probably find someone on this site that would be interested in buying your old motor, and they would do the rebuild for themselves.

 

awesome posts thanks I haveno idea what to do. Of course this happens when I am dead broke
