1G dp question??

[RHDMK3]

So I was looking under the hood of an aquaintance's TTR when it ocurred to me that my engine-1G, and his engine-1JZ, both share the same turbo setup(two CT12's). Now my question, and yes I have searched this site but to no avail. Anyhow I was wondering since we both have the same turbo's and I know that our cars use the same exhaust from the cat on back would we also be using the same downpipe as well?

They are not the same turbos.

1g = CT12

1J = CT12a

I wish I had my laptop here with me. I have a picture of a CT12 next to a CT12a and the 12 is obviously smaller.

1G turbine inlet = 25mm
1J turbine inlet = 30mm
1G turbine exhaust outlet = 42mm
1J turbine exhaust outlet = 44mm
1G compressor inlet = 31mm
1J compressor inlet = 38mm
1G compressor outlet (to intake manifold) = 29mm
1J compressor outlet (to intake manifold) = 29mm

I wouldn't bet on a 1J downpipe fitting your GA70.

Really? Damnit! I was hoping I could get a dp on the cheap for my car. I'll have to keep looking around. Thanks man

When I get home I'll try to find the pic just for illustrative purposes.
