Guest Tom Scala Posted August 18, 2000 Share Posted August 18, 2000 I'm doing a L28turbo swap into my 78Z and was going to use a 83 motor. Being new to the Zcar I didn't know the 83 used hydraulic lifters. Now I'm hearing some not so good things about the hydraulics and am wondering if I should look for a p90 head instead. I didn't drive the donor car but heard it idle,no ticks. Do these p90a heads have reliability problems and are they difficult to rebuild? Thanks for any info.

Guest Fast Frog Posted August 18, 2000 Share Posted August 18, 2000 Tom: I've got some experience with ZX turbo hds. Others on this forum may have more. I swapped out my stock '76 engine in the mid '80s to do a beefy turbo setup. I chose the '82ZX turbo engine cause I wanted 7000rpm and was advised that one can't get those kind of revs with a hydraulic setup like the '83ZX. As it turned out, I seldom reached 6500 and could have gone with the hydr hd. I guess if you're into racing or other hi performance, go with the P90, if not, the P90A should be OK.

Guest Anonymous Posted October 17, 2000 Share Posted October 17, 2000 Is it possible to swap in solid lifters into a P90A head? I have a P90A head, and I've put some time into it. I haven't driven it yet, so I don't know how it'll work for me. If I find that I get leak down will my only option be to find a P90 head? ------------------ `72 240Z `81 280ZX http://admin.rootsweb.com/~aktar/zcar Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted October 18, 2000 Share Posted October 18, 2000 Do not use the P90A head, i have heard from several sources that the lifters are NLA from nissan. They also run about 15 each if i remember correctly. Do the math, thats way too much dough to risk on leaky lifters. Do yourself a favor and find a p90. I did and im glad i did, no worried or headaches. I have seen an A head converted to non hydraulic lifters before, not sure how it was done but this topic may be better posted on zcar.com. I know of more turbo guys over there that have had experience with the l28. Zon- Evan Quote Link to comment Share on other sites More sharing options...
