Well im kinda sketched out about tappin into the manifold. So i think i will just put it in the downpipe. Will i be alright if i just let off a 800 since theres 200-400 degree difference ive heard 900 is when you want to let off post turbo. What is the max temp i should run POST TURBO? in about a week i am getting php tunes so i need to get it figured out asap already got boost and trans hooked up

just tap the dang mainfold, it's not rocket science

You will be better off doing it in the exhaust manifold because you will have to replace the up pipes sooner or later so if you do it in the exhaust manifold you will only need to tap it once.

yeah if i do the manifold ive heard grease the bits and ive heard dont. Ive heard leave it running, and the way that i was gonna do it is start small to big and just use a vacum to get the shavings

Don't grease it, don't leave it running... Drill it, tap it, light a cigarette and cuddle with it... I mean drive. lol

I used to be anal about it too. But honestly, you'l be fine. Especially since it's fixed geometry. There's nothing for the shavings to get caught/hurt.
And drill it once. Starting small and drilling big just creates more and more shavings.

[bruce51d]

if you don't grease the bit the shavins will fall out and the 2 that don't will vaporize or pass by the turbine side of the turbo without and problems

[azkcr]

Ya, if you grease the bit then it will trap the shavings in there with the grease. Dunno who thought that would be a good idea.

There's a ton of opinions on how to do it, just pick one and go.

I have heard of exactly ZERO problems from anyone who has done it, and there is a ton of people who have done it

what is the drill bit size for a 1/8npt tap?

[07OUTLAW]

R (.339") or 11/32 if you don't have/can't find
