Hey, sorry i didn't reply right away i wanted to get in touch with the Datsun shop near me to see if i could pick up anything local first. Sounds like you have a good head for sale but I have a set price range so i can stay within my budget. i am trying to spend between $75 - $125 for a head, i can do all of the porting and other work myself. Plus i already have a cam and new valve seals to go in it. Looks like someone will get a good cylinder head but it's just out of my price range. Thanks again -Riley-

If they're made to be welded onto thhe original strut how could they be aluminum. You can't weld aluminium to steel. And as far as having them machined out of stainless that was my first thought. My best friend is a machinist so i asked him about it and he said it's a PITA becuase it takes a long time to turn fine threads like that on a lathe. He said it might be possible w/ a CNC but after i told him the price of the megan ones he said it would be cheaper to just buy those ones. just my .02. But if anyone has found a cheaper alternative i am more than interested.

Hi everyone, I just recently looked into the serial nine adaptors and was shocked at their price so i gave megan racing a call. It turs out they sell the same style of adaptors (apparently for a 62mm coilover) for $100 a pair. Its the same price as the S13 front coilover perches but with no unecessary bracketry on them. They have a pic of them with the Cressida kit on their site under part # MR-CDK-MX83. The only part i am unsure of is which brand of coilovers they fit besides megan ones. There is one downside however, which is that since they have to be specially ordered seperate from the kit the estimated delivery time is 2 -3 months! But if you're not in a rush it seems like a great alternative to the serial nine adaptors, or an extra set of front mounts for the S13 coileys.

I was considering the P79 too so if a Maxima head is just not practical to run i'll probably end up getting one of those. With a maxima head would unshrouding the valves lower the C/R a bit? because that may be a little more reasonable cost. The ain point I am getting at is that i am looking for the best bang for my buck in a cylinder head and from what i read the maxima one seemed to be it. I am just trying to get more info from people with that setup to reinforce my decision because it seems not too many people are running it. Thanks again for the input guys.

Yah i guess thats true, but i was hoping to have to not get a head i have to spend any extra money on wether it's a header or machine work. Thats why the MN47 caught my eye. I am pretty sure either mack or 1 fast z said they were running their setup with full advance on pump gas but i couldn't find the post it was in again. Plus if i get one of the older heads won't i have to put hardened valve seat in it?

I am trying to avoid a head w/ square exhaust ports because i already have a round port header and i am on a very tight budget. I was thinking of a shaved P90 but the cam tower shims and the machining work make it kind of a pricey option. As for the gas i can always get the 93 octane in NY state considering i buy almost all my gas there anyways. But i appreciate your input. thanks -Riley-

Come on Mack, 1 Fast Z you guys must have some input. Thanks

Hey guys, I have been doing a lot of reading on the site regarding the maxima head on an N/A L28 w/ flattops. I was just looking at getting some feedback from the people who are currently running this setup. I.E. detotnation problems you encountered, valve clearance issues, etc. I should state that i have an N42 block w/ STD bore flattops, a 490/280 cam, tiple DCOE42 webers, and an aftermarket header. I plan on building this as a hot street motor that i will use ocasionally at track days. As well, where i live i can easily get 94 ocatne fuel @ the pump, so i am hoping this setup is capable at running pump gas w/ a full 36deg advance on the timing. Any input would be greatly appreciated. Thanks.

Anyone have a maxima head they're not going to use. Need al least the valves in it i already have everything else. Thanks

lol, i didn't pay attention to the wording on that one when i read it the first time.

Definitely i will, i see he is a regular on all of the head threads i have been reading.

Well i finally got it stripped to the block, it turned out to be an l28. Now it's time for some flattops and a serious head. Thanks everyone for your input.

1973 240Z Still under construction but plan to do track days, and a lot of late night backroad runs. Also very interested as i am in the market for some coilovers right now.
