So currenty I have my 81 280zxt which is in running condition. Im doing all of the modifications that Id like to have installed once its in my 78, intercooler, mbc, FMU, fuel pump, etc. All parts are easily switched over. My 78 is being restored and is very close to finished but doesnt have an engine. I have prepped the engine bay to recieve a new engine, rewrapped the engine bay harness so its all looks nice, etc.
So heres the question and plan. I have the original 78 engine in the garage. N42 block, n47 head combo in good condition. The 81 turbo is obviously a f54 block, p90 head. I also have a set of 81 turbo pistons from my last turbo car that I parted out.
Id like to drive the 81 turbo for the rest of the summer since its all together and the car is fun to mess around with since its beat up and I dont care about how it looks but I want to get as much done on my 78 before school starts again.
Heres the two plans...
1) Leave 78 as is and wait to transfer entire engine and wiring who knows when, end of summer, winter, later.. I would have to clean up the block which would take even more time really pushing off ever driving this car.
2) Strip down n42 engine to just block, refresh the block, install turbo pistons, modify for turbo oil feed/return lines, and bolt it up in the car ready go. Purchase extra wiring harness and begin to do wiring for the turbo harness and ecu (I have a spare ecu). This plan would allow me to keep working on the 78 and in a way do the turbo swap while still being able to drive the turbo car and gain experience. I could push off actually transferring over the head and turbo till sometime this fall during school since this would be by far the easiest part of the swap. I would use the turbo pistons since from what I know they have the ring lands lower on the piston to help shield the rings from heat. I suppose Id need to find myself a turbo oil pump as well, but I have alot of the small engine parts left over from my last turbo engine to prep it to work with the turbo system. So this aspect should be pretty trouble free.
Im obviously leaning towards option two but please let me know if you see any problems or changes that woould need to be noted.
Thanks!
