Anyone know the thread size for the newer Borg turbos? Putting in my new s200sx fmw but not sure what thread size. Got a 1/4 npt it starts but then gets very tight. Any input will help.
And I think I have a -3an feed line but not 100% sure anyone know how to tell if its -3an vs -4an?

Thanks

 

The borg I had was 1/4 npt. It gets tight as npt threads are tapered. Use teflon tape and it should be fine.

 

Yeah I think its 1/4 bpt not npt. I tightened more and it wants to cut the threads.

 

DO BOT USE TEFLON TAPE. Just tighten the fitting down and it will be fine.

 

This is the kit I used for my s360, 1/4 npt to - 3 feed line. I know some say don't use sealant or tape as oil can wick through it. I've never had a problem using them, but no harm if you don't.

As stated above. Don't keep tightening it, pipe threads are tapered, and will not bottom out like a regular bolt.

 

I'm talking not even 2 full turns. It goes in about one turn then stops. I'm pretty sure its bpt vs npt. Might just get it in as far as i can and use Honda bond to seal around it.

 

The new s200 maybe different. Probably best to contact full race, borg or pm scorpion T.

 

Yeah did all 3 waiting for an answer, scorpion also thought it was a 1/4 npt but wasn't 100% sure

 

In pretty sure it is npt. My fitting didn't thread in very far either. Just turn it until it is nice and tight and you should be fine. The reason I say not to use Teflon tape is that it not only will cause AN fittings to leak sometimes but if a small piece of that tape came off and shot through your turbo that wouldn't be good at all.
