Difference between PPE gt40 and gt42 install kit?

[blue68383]

If I baught a gt40 install kit what would I have to get to install the gt42? What are the differences in the kits? The reason I ask is I know where I can get a gt40 install kit pretty cheap.
Thanks
Nate

The Downpipe is different... and there is a 2inch spacer that needs to be used and IIRC the driver side boost tube needs to modified to work

I thought it was a one inch spacer? So the downpipe is probably longer to accomadate the increased height of the turbo. What do you have to do to get the ds boost tube to work?

the boost tube is the same you will just need to get an adaptor to a v band style clamp to attatch the boost tube to the turbo.

the down pipe is either 1" or 1/2" inch bigger i cant exactly remember.

also the intake for a 42 is 5" vs a 4" with the 40

Edit i believe the down pipe is 3 1/2" on the 42 vs. 3" on the 40
