i was just in the prelude forum and i heard that you can not use aftermarket pistons in a h22 with out resleeving they also said this may also be true for F series motors does any one no if this is true i need new pistons for turbo but do not want to resleeve. any one running stock sleeves with custom pistons if so what are you running and how is it holding up???

 

the cylinder will have to be re-honed, but re-sleeved and honed if you are going larger than stock bore size

 

ya but do my sleeves contain FRM. I believe it stands for fiber reinforced metal/material. its the way the stock sleeves are constructed. h22 have it in the sleeves but i was wandering if the f series have it also...

 

If anyone has a Helm's book, it will tell you what the sleeves are in there...

Well, I remember the 92-96 honda prelude (S model) had a F22A1 motor, and I have a prelude Helm's.. So I looked it up, and said NOTHING of having FRM sleeves, but it clearly says the H motors do have them, so I would think the F motors don't.. HTH

 

You do have to resleeve the h22a for aftermarket pistons. If you don't, gaulling occurs due to the FRM cyclinders. On the f22a/b The cylinders are not FRM, so resleeving is not neccessary. Yor best bet is to contact a Piston Manufacturer like JE, Ross, or Weisco. they can tell you the specifics. Hope this helps.

Welcome to the board man, sound like you know your stuff.

 

Thanks for the welcome. I don't really claim to know much, but I have built several F series motors and I have built a couple of h series. I also built my 2.6ltr.
check it out at my site. http://www.collectiveracing.net Its in the members rides area/ blue and white accord.

 

Wow your car is insane. 2.6 liters of DOHC VTEC power? What rods did you use? I don't see rods in your extensive list of mods. What are you getting on the dyno?

 

Believe it or not I am actually using stock rods right now for N/A. I will be changing them out to eagle rods as soon as the car gets nitrous. 150+ shot Last dyno was on a different motor built by (R&D Dyno services :stay away: more on that later.) It was slightly bigger in displacement, but had less compression than I am running now. It laid down 208hp /177tq this was also untunned N/A. My new motor is not an R&D motor and I am expecting to get 230-240 whp/200 lbs/tq as soon as it is tuned.
