Is it possible to fit a 2jz exhaust onto a 7m chassis with a 1jz motor with minimal modification? Does anyone know how difficult it would be and what would need to be changed? I am not familar with the JZA80 undecarriage.

Wouldnt be very easy.

I doubt it... the car's seem to be very close in overall length, but the exhaust routing can be drastically different.... My GF has an NA MKIV... I can take pics of hers and mine and compare sometime......still somewhat different than the TT, but the routing should be the same.

If you could post pics that would be cool.
thanks. I'd like to see the difference.

you would have to reweld a new flange so it bolts up and fits.

the rear can be fitted

but the main question is WHY?

is the dp from mkiv fit to 1jz in mkiii? what modification needs to be done?

 

[SlimFastSupra]

no it's not the same

you can buy a 1jz downpipe anyhow

 

[i just died today]

iv done it with the downpipe when i had the 12b turbos, the mk4 dp is longer and the cat sits way back , on the mk3 the mk4 cat reaches the end of the tranny and the dp bends down almost touchin the ground, it has to be cut and straightend and the rest of the mk4 exhaust can fit with modds which its not worth it

the thing is that i want a 3"1jz downpipe only that will bolt on the 7m stock piping. i wnt sumthing cheap or custom my own... you guys have an idea to make one?

SupraAce, mine is for sale, but it's 2.5" at the top. No biggy since the Y pipe is 2.5" anyway. Msg me.
