Hello,i have a P/90 cylinder head that i just disassembled and sent it out to have it professionally ported and was going to turn it into a beast but it will cost for parts and technical assembly = $$$. At this juncture i'm willing to let it go with original valves, springs and retainers with cam-towers for $450. If you want it i can send pics to an e/mail or text. Let me know if i can be of any help.

I have an E/31 cyl head that comes with cam towers less camshaft in great shape $275.00+shipping.

Clean or new ? Some pics would be nice to my P/m. thank you.

When you have it off send me some pics. Thanks.

I don't joke with business, ask a machine shop. I have a mechanical engineering degree. If you were giving it away and paying for the shipping too i would not want it. Trust me i mean what i say not playing.

That head is dead with rust metal erosion. Throw that away.

I have a completely rebuilt P90 cylinder head. Send me your e/mail to my P/m and i will send pics for your view.

No key though.

I have that piece but will have to remove the push button.

I just bought a P/90 cyl head and removed all the valve train and is being ported. I may sell it if i can recover what i have invested into it. My plan was to replace the valves with longer ones and heavy springs which i already have. If interested send me a p/m to my inbox.

If it was i would make specific notes that it's an LSD and i don't think i would put it up for trade.I have a Datsun buddy that has been holding an R-200 LSD though. I have seen it myself and it looks like new. If i had the cash it would have been in my car.He wants $900. I'll check with him to see if he still has it.Let me know if you want it.

I have this NA 5/speed trans stored in my garage ever since late 90's. #2) R-200 rear diff with 3:70 ratio from a Z-31 NA automatic car. #3 R-200 with 3:54 ratio with 58k original miles. #3 Z/31 ECU's 1984-1989.I want to trade for equal value, so let me know what you have to trade. I will add more to this list as i pull parts out. I would prefer local pick up but i'm up for shipping if you make your own arrangements. I'm looking for a new set of .040 or .080 pistons with 9mm rods or any aftermarket performance rods or drive train parts. Let's deal !

I see one broken Exhaust stud are there any more i did not see in pics ? Also the larger water passage in the rear near the # 6 combustion chamber looks like some rust has eaten away some of the metal. Just send me one more pic of that spot to have a closer look. Any history of this cylinder ? thanks.

Price is a little steep for a bare cyl/head body, but some pics would be nice for consideration.Question: Do you know the history of this N42 cyl.

Looking for three N42 cylinder heads needing work but not decked with original 4.25 inches of meat. Does not have to have a camshaft just valve rockers a rocker pivot stands. Also a set of new 87mm pistons not ITM. Letme know what you have in those parts. Thanks Hyb zers.

Where in California ? I have several of those clamps for SU carbs.

I have a completely rebuilt P90 cyl head by a popular race machine shop. P/m sent to your in box.

I have three pairs one pair is new for weber down draft carbs.

I have companion flanges and an r-200 mustache bar. Send a p/m to my in box for the details.
