    It's pretty much all out there in the b18ft part of the forum. However I think Haz put a guide together and scoff was going to look over it and add some running tips? So I think Scoff has forgotten about it? maybe?

    Re: Comprehensive B18FT into R5 Conversion Guide??

    I'll give u a really basic Borge guide feela.
    Drop engine in hole using gtt gearbox mounts
    And a GTX engine mount. Frow away Volvo loom and use standalone.

    Retain Volvo down pipe and blu tack to gtt exhaust system.

    The rest I forget lol.


    On a serious 1 it is quite simple.

    Top tip. Remove original gtt fuel presure regulator
    Before fitting Volvo engine, and fit feed and return lines
    Feed line aprox 1 meter, return line aprox 1.5 meters.

    I did this in reverse and found it a rite pain

    Ok need to know all the stuff to keep, all the stuff to bin, which wires to connect to what in the gt. I have both ecu's, loom etc, but no coil, so need a suitable coil. Thats just for starters really.

    Re: Comprehensive B18FT into R5 Conversion Guide??

    right, you can bin loads of the original loom, but you compromise fuel economy and a steady idle,

    For an uncluttered wire and vacuum bay i binned:

    Idle control valve
    lambda sensor
    auxiliary water pump
    injector cooling
    electronic boost controler ( cant go over 0.9 bar on standard ignition timing ecu, unless scoff fettles with it)


    left me with wiring to :
    ecu water temp sensor
    knock sensor
    throttle position sensor (will run without this)
    coil
    ecus
    injectors
    flywheel sensor
    afm

    on the wiring harness you will see a big thick red wire, this is the power for the loom and is attached to the alt.
    On the harness is also a red female connector. You need only 3 wires from this to get the engine working in the gtt. a grey goes to accelerator run position in the gtt ignition barrel (position 2 ) yellow wire i think! Blue/white wire goes to cranking position (position 3 ) on the gtt ignition barrel, orange wire i think! grey/red wire goes to fuel pump, so cut out gtt fuel pump relay out and join to the positive wire of the fuel pump. So with those 4 wires it will fire up.

    For starter motor, rad fan and switch, keep original gtt wiring.

    Awesome matey. Just what i need.

    to clarify:

    Big red wire = + onto alternator terminal
    grey wire = yellow wire ignition barrel
    blue/white wire = orange on barrel
    grey/red = + wire of fuel pump.

    Sounds good to me. I think from there i may want to keep the lamda and ICV. Possibly the boost solenoid valve if its any use.

    yeah pretty much, just check youve got the right yellow wire as there are two, or you will keep loosing earth and the relays wont switch.

    This shows a few more wires on that red connector
    https://www.rtoc.org/files/Technical%...o%20wiring.doc

    You can also keep the gearbox speedo sensor and tee into the top half of the gtt speedo cable.

    Good day spent today, BBQ, beer and garage time, thanks to Matt and mark for making a cuppa tea

    Well over two years since I dropped it in (back then I didn't even own it) she fired up today!

    Happy birthday to me!

    Hope this works http://youtu.be/mY61Qlu0dgA

    Now then mate, thanks for the help, top banana

    Nah it was the injectors, they were stuck of all things

    We had fuel in the rail and a spark but it wouldn't run, we put a plug onto each injector and gave it 12v until it clicked open, then it fired straight up

    It died after running for a while and then when you fire it up it cuts out straight away, wonder if One of the ecu lives has come loose... They weren't soldered on.... I'll check tomorrow!

    Thanks again for the help,

    The injectors can become sticky if not been used for a while, ive done the same in the past to get them working but it's best to get them cleaned to be sure.
    It is known for the injectors to lock on and burn the ecu outputs.

    Edit: also if the coolant sensor, by stat housing for gauge, front of head for ecu one with red plug, is not working correctly then it will make it really rich, like leaving the choke fully on in a ggt on a hot summers day.
