Cool thanks guys. I can't wait to do this now. I'm gonna leave it on and do the drillin with the geasin. I've heard that it's pretty easy to drill into the manifold.

yeah it's an easy job, you'll be good to go

Drilling the manifold is easy, super soft cast iron. Almost like butter... it is surprisingly thick also.

I magnetized the drill bit then vaccumed out the hole with a super small battery operated vaccum used for cleaning keyboards/electronics, Just to make sure. no problems.

Sweet. I don't think it will be that hard, probably more of a pain in the butt.

A little more info:

I removed the 4 bolts in the top turbo flange. Spread the flanges apart 1/4" and inserted thin, stiff cardboard to prevent anything from getting into the turbo. I also set up vacuum nozzle (from shop vac) beside the drilling location when drilling & tapping the hole.

Nothing fell through and only a very small amount of metal 'dust' fell onto the cardboard.

...good luck...

Not saying im an expert at this as i have only done two. But when you let it run and your drilling it and the bit breaks what happens then? By the time you run to shut it off your turbo is gone. If its not running you can then resort to pulling the turbo. I would say do it the way i have said and add grease if you like. Just my .02!

every body is too paranoid , just drill it and be done with it! it's on the exhaust side..... i have never heard of any damage done to a turbo by drilling......... ever!

I was very, very paranoid when I installed my EGT Probe last month.

If something could go wrong, it would!

I marked the location with a Sharpie and marked the spot with a drill punch.

With the motor off, I started with a 1/8" bit and used 6 more sizes, before finally ended with a 21/64" bit.

I lighted coated each bit with grease and after each drill bit size, I used a pencil magnet and a shop vac, to clean the area.

Over kill yes, but I wanted to make sure I did this right.

Excellent pics D45. I think I'm gonna try this first. I can always take the turbo off.

I've installed about 10 pyros, 4 Dodges 6 Fords. I've never pulled the turbo, use the automotive magnet and shop vac. Matter of fact I don't know anyone that has shelled a turbo putting one in.

I've used the grease method with no problems. However, if you do decide to pull it, it is actually easier to take the manifold off than the turbo. (You can pull the exhaust manifold off and just leave the turbo in place.) Then you have the freedom to use a drill press and not have to drill in the engine bay.

Yes, running the engine is risky for the motor especially if you break a bit, but it's really a poor decision for your own safety.

More than one way to skin a cat, but using grease on a drill bit defeats the purpose of the bit design, to push the shavings out as you drill. Be sure to use cutting oil on your tap.

Thanks, I was thinking about that. I'm going to tackle this next weekend.
