Well the Z is going under the knife this winter. I have a 83 turbo parts car, and a 83 N/A. Both motors are in decent shape, with 152 XXX kms.
My plan for winter is to turbo charge with a z31 ecu, injectors, intercooler, exhaust and ka throttlebody.
I plan to use the N/A shortblock, using the turbo oil pan, but i'm not sure if its worth swapping heads too.
Being a 83, i assume the p90 has hydraulic lifters if that changes anyone's opinion.
Do you think i should keep the N/A motor sealed up with the p79 head and just swap manifolds, or use the p90 as well?
Keep in mind, i've never come close to swapping a motor, so everything i do will be a learning experience.
Also, the N/A motor has a good exhaust like at the manifold at the 6th cylinder, which i imagine is the typical snapped stud. If its broken off in the head, i guess i'd have to pull the head anyways.
Edit: Forgot to mention, the car will be my summer daily driver, built for weekend auto-x duty, thus the reason for higher compression and quicker throttle response. Alcohol injection is a consideration, but not until i have the suspension addressed.
As for power goals, whatever the block will take safely, but i have piece of mind know I always have the turbo shortblock on standby.
Please feel free to critique any other elements of my build too.
