in the 2nd gen facts i was looking in the master list of thread sizes here:
https://www.rx7club.com/showpost.php...26&postcount=5

and im not sure which size it is on the front cover?? i need a -AN fitting for my turbo oil feed coming off of the top of the front cover (was originally the banjo bolt) and im sorta confused??

heres where im lost:

1 part says:

Oil Feed Line Hole: front cover, 16mm x 1.5 thread pitch,
other three, 18mm x 1.5


and the other is:

Turbo Oil Line from the top of the front iron on the right via banjo bolt, then runs through that metal line to the turbo oil inlet: M12 x 1.5


now im guessing that the one i need is the 16MM x 1.5 and the M12 x 1.5 is the banjo bolt ON the turbo for the oil feed??

i need one to fit a -6AN female to -6 hose and i think that this is the correct one??

damn i had those an fittings size on paper somewhere bro i will see if i find it

oh you are not running a -6 for the turbo oil feed right because thats too big you will blow a lot of oil in that turbo

 

wierd thing is, i got the line with the turbo from a forum member and the line came with it. i thought it was -4 but he says its -6? ive only dealt with -10 so im not sure of the size. i figured 6 was to big also but he claims to have had no excess smoke with it?? i dont think it has a restrictor in it either!?!?! its a turbonetics 62-1

 

try it see if it works for you

 

This is what I used for the oil feed line to the turbo.

-6 works fine if the there is an only restrictor or the turbo is internally restricted.

The front cover is not M18 or M12. M18 is huge (O2 sensor), M12 is small (NA fuel rail). If I had to guess I'd say it's M14 but that's just a guess.

The stock thread for the oil feed source on the engine is M12 x 1.5 . I bought this fitting thinking that it was 1.25, but I used a die to change the pitch and it threaded right in. Then I used 4AN line with a 90 degree fitting to connect to it, and ran the line to my oil feed flange on the top of the turbo (T04S) which had a restricter in the flange.

 

Oh, it's the 13B-REW that is M14 ( https://www.rx7club.com/single-turbo-rx-7s-23/perfect-oil-fitting-adapter-13b-rew-389236/ ). Duh....

Sorry about that...

 

id rather not have to tap it though.
so its M12 x 1.5 ...correct?

 

Yes
