s13 conversion

[FLEXXX]

hello there lads sorry to be a stranger i know its been a while since ive posted anything up but here i am i was just wondering if any of you kind gentleman can put up a HOW TO do a s13 engine conversion up as i was just wondering is it as simple as plug and play or is there any tricks that i should know of any help will be much appreciated cheers

[FLEXXX]

do i take it that it is just a straight swap only needing engine,ecu and loom and it will fit straight onto the s12 gearbox and mounts and no trickery with any of the wiring etc

flexxx mate,has pukka done a how to anywhere

nope i have not. Its a very easy straight swap conversion
same gearbox and bell housing,
same engine mounts
same s12 car loom.
Just drop in the det engine
Use the s13 ecu,loom and loom ancileries ie dropping resistor and power transister and the 3 green top relays
s12 power steering and alternator can be used. Cut a chunk out the s12 power steering pump bracket to clear the wider det head or find a s13 bracket

You should be able to work it out from there as you go along.If you get stuck You know where we all are to answer any questions.

cheers mate i just needed to double check a few bits as you all know ive been a bit rusty with not having a s12 but fingers crossed all should be about to change courtesy of 30psi ive decided that i will be putting a det lump in as for two reasons easier to source than the et lump and secondly easier to find on the shelf aftermarket parts but watch this space coz its going to be mental lol

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.

brilliant pukka all i have to do now is wait for the car save some money for the det and im on my way cant wait to be back in a silvia

[PukkaSilvia]

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?
