    Default EFI Progress on my Datsun 240K

    I'm slowly getting my EFI set up done,

    I brought a MR30 skyline, to use the EFI from,
    I stripped the wiring harmes out,
    Hacked the wiring a bit, and I kept the fuse box,
    plugged it back onto the motor (still in the MR30 Skyline) to make sure it was still running,
    All appears to be good,
    started on my 240K to see where I was going to put it (ECU), I decided under ther dash, left hand side, above the parcel tray, I put a hole in the fire wall, put the wiring through to make sure it fitted,
    Now I'm hacking the inlet manifold, removing the webbing and EGR plenum,

    I've included some pictures..

    Slowing hacking away at my manifold, I found using a drill makes it easier

    you're doing this for more efficient fuel delivery or you going turbo?

    you're removing the intake flash because it looks better?

    How are you going to block up the holes underneath the manifold?

    Would have been easier to get a N42 Non EGR intake manifold off Ebay usa.

    No egr valve, no webbing, no welding up holes.

    Some one suggested threading the holes with a pipe tap, and putting in some bungs, I though about using small welsh plugs, I did do a search on ebay.com.au, and didn't come up with any hits, since I'm not in the US, the freight would be a killer, and since I'm trying to do this on the "cheap" my time is free.

    Mat Big Hat, 4 reasons, more fuel efficient, a little more power I would think, It will look nicer, and it will make it easier to get to the manifold studs. At this stage, no turbo, but when I build my L28, I want to go that way.

    aarc240, I've spent about 3 hours working on the manifold now, probably a day on the wiring, but since I'm doing it, it's not costing me $40 to $60 an hour..

    I have more picture here ..

    I filled up a whole in my K manifold with epoxy steel and drove it for one year without any problems at all. I'll post a photo shortly.

    It was a product called JB weld and was bought at a small auto shop in Australia. I'm certain this would fix your problem.

    Some more pictures,

    I may polish it a bit, but thats all the material I will be removing, carbite tools bits are to expensive to buy..

    I put in a picture on the head I will be using, I polished the ports a little, but didn't enlarge it any (except to remove a little bulge on the side in each inlet)

    Yep you'd have to get one from USA. Freight is about $40 by surface mail. Took mine about 2 months to get here.

    No NOS for me, Mr Camouflage

    I spent a few more hours today mounting the fuse box / relays and ECU, as you can see in the pictures, I dont think it looks to bad..

    Looking good!

    To fill the holes, see if there is anyone reasonably nearby who does aluminium construction, boats or bullbars

    If you can find someone then a short piece of aluminium bar can be inserted into each hole and MIG or TIG welded into place.

    I didn't go to the extent you have, just made a 5mm steel blanking plate, had it zinc electroplated & irridited gold, then bolted it on in place of the EGR valve. Looks factory stock and was easy!

    I've sent it to our welding department (TAFE Tasmania), I have spoken to one of the teachers, and hopefully he will weld it up,

    But my next hold up is where to mount my fuel pump, I had a quick look under my car, and there don't seems to any good spots to put it, and i'm not wanting to put it in the engine bay, so where has every one else put there electric fuel pump ?

    You 'should' have enough room under the boot (trunk) floor to the right front of the spare wheel well.
    It will need a sheet steel shield protection plate in front, under and at the side of the pump area.
    For filtration use something from a late Holden - spares tend to be easier to get!

    Sorry, I missed your question on the position of the pump - not that it mattered as you worked out the preferable position anyway!
    Once it's on the road check the pump and surrounding area for gravel rash or any sign of stone/debris impact - just add a simple steel shield if you spot any.
    If you had the luxury of painting the entire underfloor not too many would even realise that pump wasn't a standard fitting.
    Looking good on the EFI conversion!
