yenghua Posted August 12, 2007 Share Posted August 12, 2007 sorry to ask but i've been reading alot of the postings in this forum which is very helpful but i do have questions, is there a difference in the f54 block that came in the nonturbo 280zx and the turbo 280zx, internally or externally? and if you had a non turbo zx motor and swapped the head to a p90 would you have the turbo engine setup? again sorry for asking i may have missed this point somewhere else in the forum.

e_racer1999 Posted August 12, 2007 Share Posted August 12, 2007 diff is in the pistons: dished for turbo flat top for some non-turbo Quote Link to comment Share on other sites More sharing options...
JSM Posted August 14, 2007 Share Posted August 14, 2007 Knock sensor, oil pan, and not just the pistons but the rings as well. Look at the pistons on the last Pic of this thread. http://forums.hybridz.org/showthread.php?t=122170&page=2 Quote Link to comment Share on other sites More sharing options...
yenghua Posted August 14, 2007 Author Share Posted August 14, 2007 hey thanks. that was the specifics that i wanted to know. so i guess if you take the n/a block and put dished pistons in with a p90 head it wouldn't be quite the same as the turbo engine right?

Quite a few folks have turbo'd NA blocks that I can tell from reading around here. Just less boost. I think the big difference is just the Pistons and rings. You can always buy a turbo oil pan or make your own. And also drill and tap the hole for the sensor in the block. Quote Link to comment Share on other sites More sharing options...
yenghua Posted August 15, 2007 Author Share Posted August 15, 2007 yeah i came across some info like that too. i guess my best bet is to just get a whole turbo motor. so how many horses will a stock L28et have with 10-12 psi? Quote Link to comment Share on other sites More sharing options...
