triton0708

So my cousin gave me his WH1-C turbo off of his 1994 CTD. I still have my stock turbo on my 91.5. (I reckon it is a 21cm housing.) I am guessing his is a 12cm housing?? But it looks as if it has a wastegate on it. Can I use this, and if so, where and how do I hook up the wastegate???
If needed, I can take pics of his turbo, but I'm sure you guys can show me the light without them.
Thanks a ton, Jeff

There should be a hole in the compressor housing outlet to screw a fitting into, then run a hose to the wastegate.

If there's no hole, make one I don't have any pics handy, but I'm sure someone will chime in with some!

Another way to run the wastegate would be to tee off the intake port for the boost gauge, and run a manual boost controller (available on ebay for under $50). That way you could adjust at what boost pressure the wastegate will open.

The WHIC will spool quicker and has a slightly better compressor than your stock turbo.

Unless there's something wrong with the WH1C, just swap the whole turbo on.

I like running the wastegate off manifold boost so it's not affected by air temp so much. I used a 5 foot piece of brake line under the engine for a clean look.
