Got a 33 in the workshop with an unknown built motor from Japan, used to be a drag car apparently, it has WU3 stamped on top of the pistons. Any ideas what make they will be?

Flat top pistons with valve cut outs and WU3 stamped on them, will get the bore scope in there in the next few days, i hope they're not stock because its had 700+hp up it for the last four years lmao!!

Thanks guys.

Yes, 05U are the stock piston code, i've searched the net quite a bit and havent yet found anything, looking at the Wiseco pistons, they do look very similar, would be nice to be certain though!

:thumbsup:

Hard work isn't it! Id like to know what they are but its not worth opening up the engine for as everything's working fine, just nosy I guess! I presume they are off the shelf, I'm inclined to think wiseco but not sure why!

well i have made up my mind going to run it until it goes boom :)

got a n1 block so we can bor it to 88 if it goes that bad :)

i'm sure they are not stock but i'm not sure off the rods so we are going to keep the revs under 8k
