I have a Dc2 b18c JDM block...I want to use P73-00 +0.25mm pistons with forged rods but i can't find any that are press fit!

Help

why run stock pistons with forged rods? either upgrade both or dont upgrade at all.

but to answer your question, you'll probably need to have them modified by a machine shop.

Where I want to race my car I have to keep an OEM piston

Is that the onlyway...I was hoping for an i-beam rod that could do press fit!

keep the stock rods then. upgrade to arp rod bolts if you must.

I did that in my last Ls vtec because at 8mm the OEM bolts where week and I was spining it to 8500rpm (balanced crank assembly aswell) So I have full confidence that I wouldn't spin a bearing at 9200rpm in the b18c ITR with them...I realy wanted lighter!

why are you spinning it that high? what cams are you going to use that make power that high? is this a track car?

i had my bone stock US ITR bottom end at 9500 RPM more times than i can remember. no problems. spoon has to run stock parts too, but they trust honda

Yes it's a track car only. I have a ported type r head with welded quech pads reshaped and balanced CCs with a 5 angle valve job. 64mm TB and ported Type R manifold then out a N1 Spoon header...I'm using Skunk2 PRO1 cams!

9500 is a bit high, I beleive that at 9100rpm you reach 2195 fps... spoon B18c's peak arround 8200rpm (don't get me wrong I love spoon, I have a 1.5 dif and a header from them)

I'm expecting to peak arround 8600-8800rpm with the SK2 pro1 cams.

Anyone have any more feedback on this??

I also had a race that need to run OEM piston, and i wanted to run the car safely to 9200rpm as well have a lighter rods to reduce rotating assemdly.
