87 Nissan 200SX s12 s14 SR20DET build!
 

Hello my name is Christian I've been on Zilvia for awhile now and I've owned about 14 different s13s, s14s.
They are awesome cars however I wanted to build something a little different so I purchased this s12 off a guy in Long Beach for cheap back in August of 2019.
It took me a full year to get it to where it is now, when I bought the car it came with
full s13 front suspension stance coilovers, pbm arms
rear s13 subframe conversion which not a lot of s12 guys do cuz its pretty hard
tomei 2 way diff
fully adjustable arms in the rear with Porsche shocks and z32 aluminum uprights

this is how it looked when I had the car picked up(not me in photo lol):

this one is a little rarer because it came with a vg30e but the car wasn't running
and I had my mind set on swapping a sr in it so out goes the vg:sadwavey:

Once I had the motor pulled it was time to prep the engine bay for paint.
this isn't a show car so I just rattle canned it black came out ok.

Also before I painted the bay I made holes for the IC piping
they're not perfect, I also added rubber grommet

the rear hatch glass was shattered and trying to find parts like that for
these cars is a bitch! its not like 240sx where there's plenty of parts
luckily I found a guy in Oakland so I drove 5 hours to pick it up
and this is how we strapped it to my friends Yaris lol

already assembled and was bored .020 over

ACL race bearings
Eagle H beam connecting rods

the motor was missing a few things I had to piece together
but got everything for $1200 which I thought was a really good deal!

putting the motor in for test fit. the sr bolts right into
the s12 but since the car had a vg30 they sit higher
so that's why I got bmw motor mounts to lower it.
oh and I did all this by myself in my garage!!

Nice work. Cool project!

Great parts, excited to see an S12 done right for once.

Question, do you know if all ACT flywheels aren't proprietary? What model is yours, and are you sure an Exedy clutch is compatible?

Thanks!

Thanks man I appreciate it!

Thank u sir! I actually meant to say it is a XTD lightweight flywheel not a ACT sorry about the confusion!

You have an interesting build out there. It seems like this car will keep you busy. Good luck and have fun modifying this car.
