HELPMY240Z Posted February 4, 2009 Share Posted February 4, 2009 I recently bought the car and unfortunately discovered the engine is crap. So i found two engines.......one of them is from the same year and comression is #150 with a 30 day warranty. The second engine is from a 1980 280zx and is currently running in the vehicle with 120 day warranty. Both are the same price, but I was wondering which swap would be easier to complete. Also what are the changes I would need to make in order to swap an L28et instead. Thanks JP Quote Link to comment Share on other sites More sharing options...
AK-Z Posted February 5, 2009 Share Posted February 5, 2009 what car is it going into? 240z? if thats the case. I would say the L28et. You are going to have to do the same amount of work putting in the 77 L28e as you would with the zx motor, thats if you are wanting to convert to EFI. If you just want it running, you can just detach the intake and exhaust sides of the engine and slap them on the new one. With this I would go with the 77 because the compression on the zx block wouldn't be high enough. Quote Link to comment Share on other sites More sharing options...
HELPMY240Z Posted February 5, 2009 Author Share Posted February 5, 2009 Today I found a 72 240z for $700 in real good shape....but i want to get my 77 280z running first. I think I am going to do the 77 L28e swap. Is there a way for me to search for hybridz users in Arizona? JP Quote Link to comment Share on other sites More sharing options...

FlatBlack Posted February 6, 2009 Share Posted February 6, 2009 If you just want it running, you can just detach the intake and exhaust sides of the engine and slap them on the new one. With this I would go with the 77 because the compression on the zx block wouldn't be high enough. Check out Lengine or the ozdata [or whatever] calculator - the Late NA L28 [F54 block+flat top pistons/P79 Head], has a higher compression than the dished piston early L28. Go with it if your keeping it NA for a while, go with the earlier one if you are going to boost it. Quote Link to comment Share on other sites More sharing options...
