Can anyone tell me what the internal diameter is of the compressor outlet on the stock 1.6TD Garrett turbo and the inlet "elbow" on the intake? Possibly 1.75"?
I'm not in a position where I can take my car apart to measure at the moment...just thought someone would have a spare turbo or intake to measure for me.
I've got a Starion intercooler on the way and I want to round up my intercooler piping and silicone pieces. Am I correct in assuming that the IC piping should be around the same size as the turbo outlet and intake elbow I.D? I don't need big flashy chrome piping...I'm aiming for a good flowing system. What diameters have others used?
-
I'm pretty sure the ID of the VW T3 comp. outlet is close to 1.5". I used a short section of rubber hose between the comp. outlet flange and the bigger rubber hose that was used in the rest of the air-air system, which is 2.25" Al. tube. A bigger charge pipe system might mean the boost threshold is a little longer, but max flow will be better.
-
Anyone else have any input as to what diameter the IC piping should be on the 1.6 TD? Don't want to go bigger than I have to and decrease velocity / increase lag...
-
i'm most likely going with 2" or 2 1/4 with i actually do it
-
So 2.5 would be a little overkill? im just starting to look at an intercooler install on my 1.9 idi. i will be using a audi 5000 intercooler i think....i also have a srt-4 front mount....but i was gonna use that on my g60....maybe ill use it on the diesel!!!!
-
2.5 would be nice, I had a hard time finding 2.5 aluminum... and the 2 1/4 was $18USD per U bend, had to draw the line somewhere. If you plan on running high boost I'd say go for it.

What do you guys think about a kit like this??

it looks like a good deal!!
let me know please!!
thanks

Should all pipework beyond intercooler be lagged to stop engine compartment reheating?

It looks unbelievable deal - where is the catch?

Probably the shipping price to Canada. Other then that I can't see any catches...

[/size]
Yes :shock:

i had 2 inch plumbing on my old truck with a (inefficient) saab 900 ic
lol im cheap i used exhaust pipe :lol:
use mandral bent pipe at least too
-
Looks good to me,the important thing is that it has teh bar and plate IC.Shipping and dutys could cost though.
-
It says shipping 150 US :shock:

I am able to get around duty fees and shipping to canada....i have an address in the US.
I think i will go ahead and buy it...ill let you guys know how it turns out!!!

Well, I did some measuring and it appears that the garrett turbo outlet is just about 2" in OD / slightly larger than 1.75" ID. The intake "spigot" is just over 1.75" as well...
I'm opting for 2" piping for my setup. I figure it'll keep the ID roughly diameter constant from turbo to intake and hopefully keep velocity up. Should be easier to squeeze into the mk1 as well...
I'm using a Mitsubishi Starion / Conquest TSI intercooler with modified end tanks. Should work pretty well, all metal design and it was cheap on ebay ($40).
I had the option of doing stainless piping, but I went with 2" mandrel bends from Summit instead. At $15 each, the bends are cheap and I'll be able to wrinkle coat them just like my valve cover and the timing belt cover. I did have to order an aluminum 2" mandrel bend to redo the intercooler inlet/outlet, but that was around $30 for a quality 6061 piece (I've heard the ones on ebay are suspect / low quality).
The only thing I've got left is the silicone couplers and I won't know which ones I need until we start fabbing it up. Anyone got a source for cheap (but quality) silicone hoses? Some of those things can be $30-40 each.
