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.
-
Perfect. Thanks everyone!

add the TD pump and then add a turbo

add the TD pump and then add a turbo
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.

why not just replace the seals.....
-
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.

i hear ya, hope all goes will with your son :-\
isnt the labor going to be the same to replace the seal on the high pressure side as it it would be to swap the pumps....
if we are talking about the same seal you can do with the pump still in the car
-
Yes it will ultimately be the same labour.. but with much higher chance of something going wrong..
NOT TO MENTION This pump is gilesefied! Meaning!?!? It will still kick ass on an non turbo motor.
-
I don't want to do just the high side. If I'm going to do it I'm doing the whole thing. That, and the lack of experience resealing an IP is what is making lean toward just installing another pump. I can do that a lot easier (fingers crossed) and I've got about 2 hours tonight so hopefully it'll be back on the road tomorrow.
