[Vr4junkie]

Just got theses in today but the box the pistons came in threw me off a bit would think they would be the same as the ring box but what do you guys think heres a few pics and link were i bought them click

im not saying they are not. but the last set i got came in a box that was similar to the box of rings. color was a little lighter on the yellow. but they also weren't for a 4G63.

Why does the rings box say "4G63SOHC"?

 

[fuel]

perhaps they share the same rings?

Nippon Racing...NPR? All of the NPR pistons I have installed have came in a similar box with the same type of box for the rings. I just looked at a couple of sets I have on the shelf for Honda's and they look like they could be the same piston as the one in your picture. I would be pretty sure those are NPR pistons!

Quoting Terry Posten:

Maybe It's for a 4g63 Single Over Head Cam engine.

^^ not judging by those pistons which are for the DOHC turbo engines!

just to double check did I buy Chinese pistons?

From my research back in the day the F1 at the end = 2g pistons, 8.5:1 CR.

Not sure if they're knock-offs, look like OEM stampings to me...

Heres a pic of another set of pistons i ordered for a ka24e the boxes are totally different ones Nippon Racing and the other is Nippon Piston Ring

BTW, can't tell you where they were made, but the writing on the white box is Japanese, not Chinese. /ubbthreads/images/graemlins/wink.gif(see other thread).

Writings Japanese let's just hope the pistons are too would hate to build this motor with knock off pistons.

Knockoffs my friend... They still use old casting numbers vs OE replacement ones.
Ive got a set of 2G factory pistons in box still, ill take some pics of the major difference.
Dont lean on them too hard /ubbthreads/images/graemlins/wink.gif
