if it's the SOHC G32b engine I think it's 9b, same turbo's that come in a pair in the 3000 GT if I'm not mistaken.

TD04 9B or could be a 9A. No CSM's ever came stock with a 15G

15G sounds like RVR territory?

Yea, it wa off a SOHC g32b motor. Thanks for the replies as I could never truly find a direct answer.

Now for a brain teaser for you guys!

What do you call a 13g/9b hybrid? And what wastegate actuator would work? I used a DSM cool side off a 13g and the 3 bolt 9b hot side off the CSM. I'll tell you the 9b actuator does not fit lol.

What ever hot side you go with 13g/9b you'll need the matching WG actuator. If you look at the WG levers on both those hot sides you'll see that they move in opposite directions. I have a 13g on my 9b hot side and am using the 9b actuator; nothing bolts up so you'll need to get creative.

[edit] I'd also call it a 13g/9b hybrid :wink:

You have pics of the way you mounted it? I can't seem to find a way to get it to work with the J pipe. However creativity will have to be the topic of it. Are you running a FMIC? So the actuators work opposite ways of eachother? I never had the hot side of the 13g or actuator.

So after playing with it I figured out how to use the 9b's actuator. The 13g has a bolt that originally held a water line to the housing. Utilizing this I was able to bolt the actuator on putting the arm 2 inches at a 90 degree angle from the flapper. All I needed was some kind of 90 "L" Shaped bracket and it worked! However in the process of bench testing it the bolt came off the compressor wheel and it started to squel really badly. However no damaged was done I cannot get the tightening of this bolt 100% correct, even thread locker couldn't hold it on.

You'll have to pull it off the exhaust housing and use a 12 point 12 mm wrench on the exhaust side to stop the shaft from moving while you tighten the compressor bolt.

Post some pics. Search for post by me, I've taken and posted a few.

I clocked mine to point down. I also used that water line bracket bolt hole and simply got some iron and drilled/cut/bent a piece to get the desired extension to be able to mount the actuator.
