I did it that way one time, I think it is easier pulling out the top. I've had an engine and trans out in an hour that way, without a hoist. Disconnecting brake lines isn't hard I suppose but it is messy and you have to bleed them after, before you can enjoy your fresh turbo redblock - such a chore!

And then obviously you have removed the crossmember and the struts and you will probably have altered your wheel alignment

Yeah you’re probably right. I do need to bleed the brakes, but thinking about how massive it is to remove the whole suspension and crossmember, it does seem a bit crazy and possibly dangerous with all that weight etc. and centre of mass shifting on the hoist. I think I may pull the bonnet off as a precaution then I don’t have to worry as much about being able to get the engine up high enough. Every time I pull an engine out it seems like the top of the hoist wants to go thru the bonnet. One of the nice things about that 740 hinge design I guess! :)

Makes me feel better knowing that your B230Ft swap is taking even longer than mine Greg. ?. I think most of us are afflicted with the same issues though: 1) we get distracted by other projects 2) scope creep.

    For me I think it’s the fear that once I get into it, the hoist will be tied up for like 2 years, probably because of 1) and 2) above LOL!

    a year later

    OK, so I decided I'd finally get started on this project. Wayne had commandeered one of the shed bays for his work stuff...which meant I didn't have room as I was having to use the hoist bay for one of the everyday cars. That's not really a good excuse - to be honest I've had a bit of a lack of motivation lately. I had a pretty big push with all those cars I wrecked during COVID, and also the re-build of the yellow 245 "barn find" project, then I guess I just had enough. But now I feel like if I don't get started on this my brain is going to turn to mush and I'm going to forget how to do things.

    We're about finished re-organising things to make room, so watch this space. I've had the turbo engine & manual gearbox sitting around since August 2004...in dry storage, so hopefully it'll be OK. Maybe the project will be complete by August 2024...and I can have a 20th anniversary celebration LOL!

    Glad to hear it is happening, I found when faced with a daunting project, to just keep chipping away at it. Even if it's just cleaning and tidying your workspace:)

    I respect your commitment to your project!

    So many people will sell up after a relatively short stall of the project, not that I am judging them, but good to see you working towards seeing the project through to the end after nearly two decades ?

    I feel that! The last year or so I've been trying to just enjoy driving my stupid cars around for once. The will to tinker is slowly returning, but I definitely took on too many projects over COVID and got burned out by it.

    Looking forward to seeing progress on this project - if your past ones are a guide of what to expect, lots of good photos and reading are in store for us.

      Thanks Bob. At the moment I'm playing Tetris with cars and parts, which meant a few distractions...decided to play wheel bingo and took the 15-inch ipd Virgo replicas off the yellow 245 and put the 17-inch ipd Pegasus replics back on. No pics yet as I got distracted checking for a clunk in the LHF suspension...then decided to clean wheels before putting them away, then coffee time, looking for an airbag clock spring for somebody, etc. Might move the gold car onto the hoist today then it all starts. Also tested out my new Milwaukee tyre inflator (Total Tools had some sale yesterday 20% off credit, so I got it for basically nothing using the credit from purchase of an E-Go self-propelled mower for Wayne). Works well but I don't like the screw-on valve fitting as it lets out a small amount of air when unscrewing. Guess I can always set the pressure 1 PSI higher to compensate.

      Car is now in the hoist bay...I'm pacing myself! I started making a checklist/to-do list for the project.

      Swap out ECUs (test before pulling engine?)

      Need crank holding tool back from Greg Cameron

      Remove gearbox and check flywheel type - swap with LH2.4 flywheel if need be

      Notch bellhousing for crank sensor

      Install pilot bearing

      Check clutch fork

      Before turning over engine - lubricate front and rear crank and cam seals

      Remove and check plugs

      Source injectors?

      Lengthen AMM lead

      Intercooler upper mounts

      Radiator fan brackets for 740 shroud

      Davies-Craig fan controller, or ECU fan controlled from 940 ECU with 850 fan relays?

      Replace ECU coolant temp sensor

      Replace/swap engine gauge coolant temp sensor

      Remove distributor blanking plate - need to swap intermediate shaft if no gears

      Remove intermediate shaft WHILE OIL PAN is OFF!!

      740T coolant bottle/brackets

      Solution for oil cooler lines

      Downpipe

      240 or 740T cat, or aftermarket cat?

      Solution to join cat to 240T exhaust

      Install trailer hitch while exhaust is out? Need to remove from paddock basher or source other style <--low priority

      Solution for air filter and washer fluid bottle

      Solution for driveshaft

      Solution for transmission mount

      Wiring and install of Turbo + kit

      Wiring and install of oil pressure sender on engine

      O2 sensor/wiring/location TBC

      Wiring installation for overdrive/relay - while dash is out - plus modify cluster lens light appropriately for "OD" or "5"

      Remove dash and tidy up wiring for accessories and gauges

      Fit clutch pedal box (check and lubricate pedal bushings

      Drill hole for clutch master cylinder

      Fit clutch master, pipe and slave/hose before reinstalling engine

      Strarted looking through my tubs of spare parts and stuff that I've accumulated over the past decades for this project...it's kinda like the mother-in-law who keeps buying condensed milk when she's got 10 cans in the pantry already LOL! How many new clutch master cylinders do I need etc! Once I get thru everything I'll need to have another sale!

      16 days later

      Getting a bit more organised. I discovered the ECU and EZKs I have (both sets) are from my dad in the USA, and he tested them all in his 240, so saves me the trouble of that step. EZKs both have same number; ECUs different, so will research which one is best. Still wondering whether it would be fairly easy to control the electric fan with the ECU instead of one of the Davies-Craig fan controllers I have. Less messy, but I need to research how it's done on the 940. Looks like the 850 fan I have will fit pretty well inside the 740T fan shroud with some sort of brackets to hold it in place. Will need to check clearance to water pump pulley. I have 2x 740T master cylinder heat shields. Holding it up to the master cylinder in the 240, it looks like the rearward brake pipe will foul the shield. Need to look at some pics of the brake pipes on a 740 I guess. The 740T master cylinder looks identical to the 240 one with same pipe fitting locations, so the pipe must just be bent differently on the 740?

      I am quite interested to know how you go retrofitting ECU rad fan control.

        I'll start doing some digging on it.

        If you use 940 ecu's and a 940 thermo controller as well as lh2.4 coolant temp sensor, all you need to do is connect 10 and 11 (high/low speed) on the jetronic (fuel) ecu to the pins on the thermo relay

        See diagram https://ozvolvo.org/discussion/9733/bosch-lh-jetronic-2-4-ecu-and-ezk-pinout-tables

        The thermofan controller has constant 12v from the battery and the way the fans turn on is by switching them to ground, this makes it easy if you wanted to hook up a manual switch

          Thanks. The fan I have is from an 850 and looks to have a black earth wire and a red and a green wire (I assume +12V for the low and high speeds). I don't have a 940 fan controller so will have to see what it looks like, or whether I can just grab the ECU signals and a couple relays to make it work.

            afaik the 850 thermo controllers are the same, otherwise just grab one of these and run it independently to lh2.4, which will likely be the most reliable way. If you dont have the a/c compressor hooked up sometimes it sends the fans psycho https://thermofans.com.au/products/digital-fan-switch-universal-0444

              I wondered about that. I do have functioning AC, and on the 91 240 there's a pusher fan in front of the radiator. Wondering if maybe that can be removed if I use the 940/850 fan set-up?

              I didn't like having to use the Volvo relays on the last efan I did, I wanted to use a standard off the shelf relay, I think I went with a 40A I think. I didn't wire low speed at all, only high speed, I forget if it's just one wire or both of them together.

              @carnut222 if you decide you have too many clutch master cylinders, I will buy one!

              Also out of curiosity, maybe you already mentioned and I missed it, are you using a 740T intercooler or something custom/off the shelf/etc?
