beeto Posted November 12, 2016 Share Posted November 12, 2016 Hi all, Im fairly new when it comes to engine work so wanted to get some opinions. I am building a L28 street 240z. I have a F54 Block, P90a Head with 3x40dcoe. I am looking at a rebuild in the very neer future and wondering what i should defiantly replace, and what still would have life in it. I am looking at a faily stock(ish) build, but a setup that wont restrict the webers at all so a cam that would suit. I was thinking a MSA stage 2 cam? Any thoughts or opinions would be appreciated. Im from NZ so parts will be comi g from the US most likely. Cheers, Jason Quote Link to comment Share on other sites More sharing options...
Samurai7one Posted November 16, 2016 Share Posted November 16, 2016 (edited) I thought I read somewhere that a high lift cam doesn't work well with the p90a head due to the hydraulic lifters?.?. Other than that I think the stage 2 cam is probably a good idea. Probably put some fresh timing components on it. Or get one of the Kameari adjustable tensioning gears ($$$) and adjustable cam gear. While you are at it, I recommend you do some porting on the head & intake. While I didn't do any on my shaved P90 head, the general concinsous here, based on what I have read in many posts, is that porting/polishing can unlock some hidden ponies. I'll get that done next time. Is your head shaved? I think the compression ratio may be a little low for NA performance if not. Consider the octane rating available to you down there before shaving it. I have to run 93 octane or I get some pinging.

Andreas Posted November 16, 2016 Share Posted November 16, 2016 Iv heard the same about that the p90a dont work with high lift cams. And take the stage 3 cam that msa sells. I have that in my engine and it workes great. Great idle and performence. Quote Link to comment Share on other sites More sharing options...
Samurai7one Posted November 16, 2016 Share Posted November 16, 2016 I run an old Crane cam 168-0012 dual pattern cam. It has a nice smooth idle that I desired since I'm running a/c. I believe it's a stage 1 cam. If I were not running a/c I would want a stage three cam. Quote Link to comment Share on other sites More sharing options...
madkaw Posted November 17, 2016 Share Posted November 17, 2016 Change the lifters to solid and put whatever you want in there as far as cam Quote Link to comment Share on other sites More sharing options...
HuD 91gt Posted November 18, 2016 Share Posted November 18, 2016 There are P90a head's that do not have hydraulic lifters. Quote Link to comment Share on other sites More sharing options...
beeto Posted November 18, 2016 Author Share Posted November 18, 2016 I think mine has solid lifter, when i hsd the valve cover off i remember solid lifters. Any reputable parts suppliers? Seems like some big price variances as i look around for parts. Quote Link to comment Share on other sites More sharing options...
