logistics of running a Giles'd TD pump on a NA?

Looking at options. Thinking of having Giles do up a NA pump and a TD pump but if I can get away with just paying for the TD pump to be pimped, my wallet (and wife) would prefer that route. I'm worried about not being able to turn the fuel down enough if I have him build the TD pump for a modded engine and then run it on my NA until I get my TD engine rebuilt.
Bring on the facts, figures, and personal experiences!

I dont have any personal experiences with Giles pumps..
But... I dont see why the adjustments wouldn't go far enough to run a na pump

While running a TD pump on the NA won't be ideal it would be very possible. I doubt you would have to turn the pump down much, if at all.

I ran a Giles TD pump on my 1.5 while I was working on the 1.6/1.9 compound build. The engine ran great. Very little smoke, way better throttle responce. Now it is on the new engine and it runs even better with boost on the LDA.

Ok, I could probably "trial and error" it but for the sake of a second opinion, what do I need to block off, disable, or otherwise manipulate on the TD pump to run it on the NA?
And what should I set the timing to? NA specs? I don't have my Bentley in front of me but I do have one and have times a couple NA's before.

I do believe Giles recommends 0.95mm.

Just slap it on and go. The space ship on top is where boost goes. Just plug up the line so nothing gets in there.
As for timing, set it to .95mm and be done. If you don't like it there advance it a little. On my 1.5 I had it at between 1 and 1.05. The compression was down so I was trying to compensate for it.

It runs just fine. The only "mod" you need make to the pump is an ~1/8" vacuum cap to block the line from the LDA.

I've got a complete turbo engine/trans that I just pulled out of an '83 Jetta coupe. Once I rebuild the engine I'm swapping it in. The problem is the IP that's on my caddy now leaks out the high side so I need something to get me by for a bit whilst I ready the TD for install. Don't worry, it will be done.

honestly, because I have more important things on my plate at the moment. 16 credits at school, Wife and 2 kids (one of which has a breathing thing called laryngomalacia), a house in the middle of remodeling and a yard that is also under construction. I just want something to get me through the next couple months until I am done with school for a bit and can reseal the 2 NA IP's I already have reseal kits for
It's been busy with my 6 month old sons hospital visits/surgery.
wow. </sob story>

just throw the TD pump on there. if you are super worried about it, put the n/a pump top on there. then it will work just like its supposed to.

Injection lines are the only thing you will "need" to add and even those you can get away without.
Depending on the health of your engine and injectors 0.90-1.00 is probably good.
