s13 conversion

[turbozx]

i have a couple of questions on this subject

the s13 ecu has a speed sensor input, but as far as im aware s12 and Bluebirds turbos dont have a speed sensor, so this cannot be connected does this matter, what did you do?

the other gray area is a feed for the rev counter s13 are driven form the ecu were as s12s take a feed from the coil pack, i have heard that using a feed off each coil pack with a dioide on each can work?

i have a loom made ready to do the conversion in a bluebird turbo but am unsure about these to aspects!

I never connected the speed sensor.It is fine.
Rather than faff about with diodes i just fitted an aftermarket rev counter with shift light on my dash and connected that to the signal wire from the s13 ecu (Yellow / Red stripe=tacho signal). It also works fine.

Make sure its definatly what you want to do. Budget for a decent turbo as an old s12 t2 will be naff.Also think about a decent clutch at least an exedy s13 unit. Also you should fit a walbro fuel pump aswell and some sort of intercooler.


Bare that in mind as in a weekend and for quarter of the £ you could get a healthy s12 engine setup done

Det engines are great fun though

Are you definatly getting martins s12 then?

i have thought of it long and hard since ive got rid of both my s12 and the s13 route i will take it will be a long and slow journey coz i still aint got a job atleast it will be in my garage and keep me close to the club as i have been designing the ideal mods and this one is going to be a sleeper
