can i put a turbo from a turbo diesel in my 83 gti its just got the stock motor. if i can does the exhaust manifold bolt up. do i need to run an intercooler. about how much boost does one put out. and would i have to lower the compression of the motor

im not trying to get a whole lot of proformance just a little something extra and his guy at my work wants to help me do it. i know there are other ways to get power i just think it would be cool.

When the hell did you get a GTI?

Yeah, the turbo and manifold will fit but since you have to flip the manifold and turbo to make them fit you'll have to make your own downpipe. If you don't flip them it wont clear the intake manifold.

The turbo on the turbo diesel it fairly small so don't expect gobs of power, but do expect lots of bottom end and fast spool-up time. I'm not sure what it will run for boost, but with a boost controller it's adjustable.

You need an intercooler on anything making more than 6psi... period.

Your compression is perfect. 8.5:1. It will take 20psi if you want, but I wouldn't do it every day. Those bottom ends are tanks.

There are a few ways to keep up on the fuel side of things. Check out http://home.comcast.net/~vwmikelvw/ and go to tech. E-mail him if you want... tell him I sent you. You know his car.

so where would i find an intercooler for it did the rabbit turbo diesel come with an intercooler

Turbo diesels didn't have ICs. Junkyard... ebay... something like that. Not too many ICs fit a Rabbit real well. Starion/Conquest intercoolers are a favorite and seem to fit soso. Probe/Mazda MX6 intercoolers work pretty well and fit too.

so what about something like this

http://cgi.ebay.com/ebaymotors/ws/eB...category=33742.

so where would be a good place to mount an intercooler i know in the air flow but i dont think there are a lot of spots on a rabbit to keep it hidden. maybe in front of the the radiator but then wouldnt the air flow to the radiator be reduced alot

It needs to be in front of the radiator, otherwise it becomes a charge air heater. You wont see any cooling system issues since an intercooler isn't hot unless your in boost, which usually is only a couple seconds at a time, and especially because the Rabbit cooling system is overbuilt.

I'm not sure where you'd fit that 2g DSM intercooler unless you welded different tanks to it.

ok so what about a saab intercooler i saw a post on vortex and saw a couple people using that are there any cons to using that.

No cons that I know of other than it's not really easy to fit. They're pretty good cores and on ebay all the time.

as far as the parts you'll be using, nothign spectacular. The downpipe offset was a little different, but you wont be using it. MK2s came with a KKK turbo while MK1s came with a Garrett.

ok is one better then the other are they both the same size

could i use a a mk1 manifold and a mk2 turbo. or what about a turbo from a mk3 diesel.

i only ask about the mk3 one because if i found one of those it would probably be in better condition then a mk1or 2.

They're the same size and interchangable. I'll have to find out about the MK3 one but I know that on the MK4 one the turbos hot side is cast into the exhaust manifold.

ok so on the fuel side of things. i read that i can use an audi 5000 fuel disturbutor to get more fuel into the engine.

now if i use this it will put more fuel into the engine will the fuel pump beable to keep up and supply the fuel or will i need a pump that flows more fuel.

MK1 or MK2 will work the same, MK3 and MK4 I'm not sure about. As for fueling, go to my buddies webpage and have a look at his CIS-E stuff. Audi 5000 and Volvo stuff has been tested and as far as my friend is concerned he didn't like it. He's pretty much the CIS turbo king.
