Turbo Oil Feed Thread Size

[cammmy]

Hi all. Not posted in a while as I haven't done much to the Esprit. Spent the last year driving it and then bought a new house and built a garage.

I'm currently fitting a GTX2863R and unfortunately the fittings from the old turbo are the wrong size for the new one. I got the old feed hose off but the fitting in the block for the oil feed is in there pretty damn tight and I don't want to risk damaging it to remove it. The plan is to get a reducer to adapt it to the feed hose that came with the turbo.

Does anyone know what thread type the fitting is? I believe it to be 1/4 BSPT but I can't be certain. I haven't been able to find this info anywhere.

Thanks

Just in case anyone needs this, it looks like the threads in the block are NPT 1/4-18 and the threads on the hose are m14x1.5

I couldn't find an adaptor that would let me leave the fitting in the block, so I took it out. It was in ridiculously tight but came out okay. I thought the block would be BSPT but the 1/4-19 fitting i Bought starts but won't go in. Measured the TPI on the existing fitting and it's 18, not 19; so I believe it's NPT. I'll post up when I know for sure.

Hopefully this helps someone in the future.

Can confirm, it was NTP, not BSP
