97 Turbo to 99 NA

Hi all,

I am new here - helping my brother out swapping in a '99 NA engine for a dead '97 Turbo. There are some differences in the wiring harnesses that I need to resolve and the Haynes manuals do not have the info I need. Would someone here have a copy of the engine wiring diagrams for these 2 engines so I can resolve the differences?

Thanks in advance,

Bill

You will most likely need to swap add the whole harness of the engine your are adding.

this is a very interesting swap... most people don't swap down...
i'm curious as to why

did you already have the NA lying around? could you not find a turbo locally?

Yes, we had the NA in a parts car that already gave us some body parts. Bought the turbo cheap with a nasty knock - it was not long for this world.

We're taking the whole engine harness and computer of course, but there are differences in the connectors that connect to the chassis harness.

the b234na as a block and heads should be basically the same as a b234 turbo right?
you should be able to install/reflash a turbo 9000 ecu on that and install all the turbo parts from the old turbo engine on there since you have all the parts right?

if i'm wrong, which i very well might be... well then oh well

Yeah I would try building the na motor as a turbo motor first.

Ahhh, you're right - Tim tells me I have it back-asswards. The 99 is the turbo, the replacement 97 is NA.

Yes and no, most people have schematics, but they are ill gotten. See the last rule states:

No Torrents Links to or public discussions regarding torrents, or any other similar material will not be tolerated.

But any copy of the WIS will have the diagrams you seek.
