Stage Water Pump

[LiQuid IcE]

I'm replacing the water pump timing belt etc. It's a 1996 series 1 Stagea RB25DET

Ordered a WP898 because that's what the supplier (Nason's) said it used on the RB25DET. Said it was the same as the RB30...

When going to install it, All the big bolts lined up. But the 6mm bolt (small one) is about 7mm off. Anyone know if the stagea water pump is different?

Even an ebay search says the Rb25 takes the same pump as Rb30

i looked at Nasons online catalogue and looks like the R34 takes a WP900... so might order that one ans see how we go.

Can anyone Save me some time and tell me the correct GMB or TruFlow part number? They should be the same.

Can I keep the WP898 for my R33 since I'll be doing that next?

Attached some pics so you can see what I mean

thanks

It would seem RB20 and RB30 are the same but different from RB25DET. Some aftermarket pumps have a slot so that they will fit either. Some people just ignore the hole that is wrong and leave that bolt out.

If you are able the best bet would be to change the pump for the correct one. If you can't return the pump you could just elongate that hole til the bolt fits and use plenty of sealer!

thanks guys. The link helped. I need to find the RB25 one or one with a slot then. Cant elongate the hole coz of the way the bend is on my one.

Thanks!
