thank you for your help,

I took both of them off of the manifold and installed them individually onto the y-pipe. reconnected my oil and coolant lines and hooked up my down pipe. Trust me, it's no where near as easy as it sounds.

That's the best way to do it. You can do it by removing only one turbo, but it makes it very hard to get all of the bolts.

If you have access to the proper equipment, hoist the engine (or jack up from the bottom), so that it's sitting as high as possible in the engine bay. This will give you some more clearance to get at the turbos.

Just so you know, since you're new to 1jz's, they like to cut and are blood thirsty

Thanks. yeah i notice when i was looking at it that it was not going to be easy. about how long would it take?

Heard it takes around 5 hours to take it appart, and about the same time to put it back together. Here's a link that might help you: http://www.thepointnet.com/Lenticular/Turbo/

I'm planning to do the same job on mine this winter, so keep us updated on how it went and difficulties you encountered.

Good luck!

 

[chuckmuska2005]

I took about 2.5 to take off and 2 to put back on so yea I guess I took about 5 hours to do everything.

[terror]

sorry cant make pic smaller

 

[pnutcar]

Yep, same as mine in my FS thread

Looks good coated!

 

[annoyingrob]

The HKS one is a beter option, as it's a full setup designed for a pair of standard T2 flanegd turbos. The ebay ones are for stock turbos.

I ran the Ebay one. It fit fine and I did it with the motor in the car. ( very difficult to get the oil and coolant lines off the rear sectioin.)
