jip jip. that sounds about rightrat wrote:Small and big job
Motor, box, raditator, management always add 5-10k for misc.
IF you want to run stock managment you need stock ecu for the motor(s13 sr/ s14 sr), afm, upper and lower wiring.
And i think you got to keep your CA speedo drive.

Ok well first off like most of the dudes said.
Motor - R6k
Box - R3k
Down pipe - R1k
exhaust - R2.5K
fuel pump - R1.2k
IC and piping - R3.5k
CA Aircon motor - R500
Radiator and piping - R1k
electric fan/s - R500 (cheapies)
Heater piping - R300
Turbo oil feed lines - R500+-
S14 AFM or Z32 if possible - R1k+
CA speed sensor - R0 - of your old box
stock wiring loom - R1k
Turbo - R1k-R14k
water pump - R500 - R1k
+- R25k without labour...
erm... think thats about it...
then labour... thats where it starts to get hairy.... I did the swop myself so no labour charge haha
drillergy said engine mounts. yes if yours are stuffed. otherwise CA works fine
Check the waterpump!! haha
rings... depending where you got the motor, but its always a good thing to check.
mmm ok... so now its management... I'm running stock S14 management.
Best will be to get a stock S14 harness and then go from there with the likes of dictator etc.
The other things to check on is the gearbox wiring. check that the neutral switch is wired correctly and that you have a CA Speed sensor in the box, otherwise it will under read by around 30-50% thus effectively doing 120km/h in a 60 zone
For me the wiring was the worst part of the job. the motor was in in just under a week but the wiring took me ages... I actually ordered a DVD from the states to get the wiring done.
The rest is pretty much drop in... gearbox works on same mounts, propshaft fits exactly, motor fits on the CA mounts. and the motor clears everything.
I did the swap myself... my car was standing for a year too. but if I had everything I needed before I did the swap I would;ve done it in a 1/8th of the time....
I did everything myself with alot of help and advice from the guys on and off the forum.
and today its running. not yet 100% but its running. haha
Gimme a shout if you wanna have a look at the swop. or if you need advice.
Will check if there is anything else that i missed...
Laters!!
