FJ60 (FLYBOX) -> 2F -> 13Bt -> 15BFT (1 Viewer)

That's a big injection pump! I have not worked out why Toyota put inline pumps on some 15Bs - I don't think any other B engines got them after 1988 (except the 1989 13B-T which was an odd halfway between early and late 3B engine designs) but I may be wrong. From what I can tell, they only went on -FTs and not on -Fs. They were fitted to both Coasters and a few Dynas, but never on JDM models. I think all European 15B-FTs came with an in-line pump, and they seem to be common on the Chinese 15Bs.

Are you going to run turbo coolant lines?

I think that accelerator rod may want straightening Would you be able to measure it please? I am looking for a 250 mm rod to keep the BJ60s accelerator crank on the 15B-T, but it has to be moved back a bit (lengthening the rod) because the intake manifold is a different design.

Turbo coolant lines are there. The turbo outlet I ordered was wrong so I cut it and welded it 90 deg so it points forward. I’ll measure tomorrow.

Pure speculation, but I've been told old-school inline pumps are more resistant to lower quality fuels?

That is a long rod you have there Sir, thank you for measuring it!

Looks like you have solved my issue on how to make a 220 mm accelerator rod without having to weld two together. Thanks for sharing pictures of your unusual 15B-FT

13Bt is out. I'll try to install the 15BFT this weekend. I need a bracket for the AC manufactured. One of the engine mounts was broken, so I dug into a box at Valley Hybrids and found 2 new ones. Will be interesting to run the 15BFT with an alternator and AC from a 1HDFT. I'll adjust the belt location with the custom brakets. 4 hours of work...

Today I dropped the engine in. Initially tried (for 4 HOURS!!!!) to drop the engine only while the transmission in the car. Never cursed so much in one day. Gave up, pulled it off the car, mated to the engine and installed. Still need to go and tighten all bolts. Now the actual fabrication work begins.

 

[ofer bruhis]

Built the brackets for the radiators today. Tomorrow Intercooler piping.

 

[roma042987]

Nice work on that bracket. Did you make the ac compressor bracket as well?

Yes, and the alternator as well.

Yes, and the alternator as well.

Any more photos of the ac bracket?

I used the OEM one that had a huge compressor and the after market one that came with the compressor from @joekatana that I bought for the troopy build (ended up using the OEM). Welded 4 tabs and screw that to the bracket that came with the engine.

Did today the intercooler piping. Tomorrow it’s going for TIG spots so we can check final fit before welding.

 

[ofer bruhis]

Battery had to move to driver side. Air box moved a bit forward. Managed to install the PS high pressure hose (from 80 series). Finished the AC hoses, and got the belts. Next is fuel and electrical.

 

[ofer bruhis]

Got the tack TIG intercooler parts to test fit. Tomorrow going back for final welding.

These 4 cylinder engines vibrate a lot. You may want to replace those couplings with single or double hump variety to try to isolate the intercooler as much as possible.

Thanks Roma. I'll put a longer silicone couplers and cut the piping a bit shorter.

This is a good idea, I'm using 90deg silicone at the IC and a single hump at the intake etc for this reason

I will say that the DI 15BFT is wayyyyyyyy smoother than the old IDI 3B's though

Interesting, I do not have my 15bft installed yet but the 15bf vibrates terribly at idle while the old 3b was smooth. Perhaps I have an injector issue with the 15bf?

That's not a great sign. My 3B's are tractor engines until they warm up. The inline IP 15BFT running on a pallet was smooth from cold first start up

My project is not complete, driving a friend's BJ40 with 15BFT it felt odd how smooth it was
