Engine rebuild and tune

[rich the mechanic]

I've decided it was well overdue a rebuild time for the original engine in my car and I am doing a little tuning while I'm there but I've run into a minor issue that the internet is crap.

I need pistons 81mm in diameter and with a compression height of 29 to 30mm and a flat top or short intruder and ideally a 20mm pin.

I think some Honda VTEC ones will suit I don't need forged, cast is fine for what I am doing. The b18c5 pistons appear to be what I'm after which I think were fitted to 1.8l integra type R engines but I can only find a full spec for aftermarket forged ones and not the orginals to confirm it all before I have to buy them.

If anyone can point me to the right place or has some to measure/sell I would be grateful.

Both Mahle and kolben Schmidt (KS) used to have awesome online piston catalogues with drawings and cross reference data, not sure if they are still there but worth a look.

Cheers have been using the accrolite site so will check those out in a mo.

Are the originals forged or hypereutectic?

I don't know it's a CVH engine so cast yes which sort no idea.

Type r pistons are domed on top and I believe have a 21mm wrist pin

Bit sure about compression height

Pins can be bushed etc, dome top no problem I'll use a hemi head just need some idea of what engine it is to get some from.

Mahle site I found not a lot and the KS one has some data but not all details which is the biggest problem I have found doing this.

AE components still make pistons. They kind of took over Hepolite.

Just found them but they only list a few pistons none that are any good for me but they do list all the details for the ones they do have which is nice.
