So i got off my *** and dissassembled my old motor. Took off the head and it's amazing to see soo many bent valves.

Bottom end was fine. Going to look at crank and bearings.

Rebuild options are to get new valves and put it back together. Ferrera seems to be the only contact on these items.

for the rest will the z32 (lifters, retainers, etc.) work?

I'll show you guys a pic tomorrow. I felt soo sorry for that motor. It didn't deserve that at all. This motor was the one that the idler pulley bolt sheared and pistons and valves made contact.

Let me know so i can order and put this old motor back together for some profit.

By the way i did use the research button and no one ever confirmed that they used the z32 stuff worked or not. RB25DET SERIES 1

I'm in the same boat with likely at least 2 bent valves. Race Engineering also sells valves to suit the RB25. "eh?" has found that the z32 lifters, collets, and retainers have the same part numbers as the ones for the RB25 so it should work. I don't have the time to do it but it wouldn't be too difficult to order one set of z32 valvetrain parts and compare them to the RB25. I priced it out last week and it comes out to less than $20 (www.mynismo.com)

BTW, if you have any UNBENT intake valves you would like to donate to my cause, I'd be really grateful!
