Got these out of a scrapped bottom end, I'd like to know what model they are from:














and just for a laugh, this is why it was it was scrapped:





Any Ideas?

 

Newage WRX

 

Really?
I was miles out, my guess was old age STi !
Any idea what year, body shape, UK/JDM etc?

 

STI engines have forged pistons, the underside is smooth and marked with HF1/2/3/4 depending on the piston type/year. Yours have a hatching on the underside which means they are cast WRX type, the piston crown is the type used in the Phase 2 and later WRX engines, they could be 1999/2000 classic? but not STI.

 

Ta!
a lot newer than I thought.
It had the alloy cover behind the flywheel which dates it as well I suppose.

I think I might need some new piston rings for that last one.
Shame there's an inch of con rod missing as well, as my mate has a mig welder I can borrow, and the hole in the crankcase has filled over nicely with some of that plastic metal stuff.

 

+1
HB twin dot pistons are 1999~2000 WRX.
Newage WRX went over to HBR twin dot pistons.

Been looking for these exact pistons for the last 6 months you wouldnt know where to get them from would you

 

I've got 4 sat in a box from a 2003 wrx if you need some. Pm me if theyre of any use

 

I took a set of identical rods from a classic wrx. They are low power items with stud and nut. I have a used set of 4 with standard size wrx pistons if you want them for the cost of postage and a drink.
