Thanks to @Redbj40 for doing all the hard work and giving away his secrets for a few beers, I'll be putting this lump into a BJ42!

15BFT, 4.1L mechanical inline injection pump, factory turbo goodness. I think it's from a Coaster due to the turbo piping and front hump sump.

Updates will be slow as I'm supposed to be working on the house and not the car ;)

Should be a nice upgrade! Much better than 13bt. Might be useful to put bigger tires.
Few pictures from the internet


I will likely run ~33" tyres. Will have a H55F 5 speed with B input spline, which I'm halfway through converting from vacuum to manual shift with twin stick as I had an extra stick and sourced the conversion parts from a 4sp gearbox.

I drove a BJ40 with 15BFT (member linked above), ordered the engine the next day! You can tell it's a bus/truck motor and is designed for torque, didn't seem to like to rev high but pulled effortlessly through the rev range and felt like it would climb anything off idle. Much smoother than a 3B, power to overtake at freeway speeds, and should be just enough turbo whistle from the CT12B to have fun without it getting annoying :)

Are you AndyBJ43 on youtube? I hadn't seen that video yet :)
 
@myusername Yes, AndyBJ43 it’s me in YouTube.

These pictures have been sent to me by my colleague some years ago. He also sent me the video, that I uploaded for you (via YouTube).

He uses 255/85 R16 tires and he is satisfied by this choice.

I just realised that the date on the youtube video was a day earlier due to the time difference :doh: Thanks for uploading it!

The olive and brown colours are rare in Australia
 
Unfortunately I’ve had some drama with the engine importer and the local roads authority, so I wasn’t sure if this would be an expensive anchor to be sent back on a pallet. It looks like everything is being sorted so I can go ahead bolting shiny bits on!

Cleaned up rocker cover and test fitted a 12V alternator from a 1HZ along with a pair of belts.

It should be noted that the 1HZ alternator has the adjuster bolt in a slightly different location so the stock belt size no longer fits. This size is just large enough to slip on, I would recommend one size larger for ease of fitment

The appropriate loom side plug is also required to be purchased with the alternator, I purchased both through an eBay seller “auto8” who was helpful enough to specify the appropriate plug in the alternator listing.

This engine is a rare version being a factory turbo inline mechanical pump. It appears to be similar to a 12HT pump but 4cyl.

The factory manuals lack material specific to this engine. This supplement (pictured) has some handy information, but I’m finding that I'm referring to RM464E 19953B, 14B, 15BF, 15BFT and a 1994 version B, 3B, 11B, 13B, 13BT FSM’s. I’ll need to find a 12HT FSM for more information on the workings of the pump as the closest I’ve found so far is the 13BT information.

This booklet was available for $10+GST through a local dealer. The others aren’t so I’m limited to PDF’s sources through mud trawling. Thanks to @Redbj40 for the tip!

Looking positive so far... apparently this is normal as advised by others on the 15B conversions fb group.

24V screen seems to heat with 12V, albeit probably slower than intended.

Will rig up a push button at some stage but it’s unlikely I’ll need to rely on glow with direct injection

If anyone wants to trade for a 12V screen let me know, I think it may be the same size as a 1HD series screen.

XR6 turbo leather seats

These are a common upgrade in Australia and adaptor rails are available. Those in the States might know the turbo “Barra” engine from some of the Aussie entrants in Drag Week from varies YouTube vids. These are the seats from a crashed Falcon, it’s Barra heart was already gone.

60 series power steering box rebuilt, with a 75 pitman arm. The shallower arm has the same effective length and taper, but doesn’t drop as far allowing more clearance to the leaf spring so I can avoid using extended shackles which are illegal and won’t pass engineering or a roadworthy if I happen to get a competent inspector.

The rest of the steering setup is a combination of Toyota parts, I’ll lay them out with a description when I’m ready to install

Rusty seized seat rails have been cleaned, treated with phosphoric acid and wire brushed before prep and paint. Good as new!

Yep, that rusty mess in the background was supposed to be a cheap parts car but is getting a 15BFT instead. I have a problem.

In Australia, you can’t legally change a shower head, fix a leaking tap or replace a light switch, but you can build a car in your backyard.

Hope I’ve put the brakes together correctly:flipoff2:

Banana 40 rods being replaced with 70 series as part of the power steering conversion.

The 70 rod ends require a larger taper. 75 knuckle arms are much beefier than the stock 40 arms and early 60 arms but it appears I’ll have to adjust the stops ~3mm so that the thicker arm doesn’t hit the shock mount.

NB: these are compatible with late model BJ42/HJ47 etc knuckles, if you have earlier knuckles the bolt pattern is smaller.

Transfer being converted from vac shift to manual.

I’m making a custom twin stick setup out of two vac shift sticks as I couldn’t find a complete manual h55F linkage setup for a reasonable price.

Vac shaft on left, manual shaft on right. Note the difference in length, location for the seal and indents for the ball and spring to index the shift.
