85 riviera?? turbo

[davidgn214]

i just bought an 85 riviera 3.8 turbo.. i wanted to know if the short block is the same as my 87 grand national.... they look the same just intake, exhaust manifolds and the accessories look diffrent

 

[novaderrik]

the block is slightly different, but functionally, the long blocks are identical, with different stuff bolted to the outside of the motor.

The '85 Riv (E-body) is a "hot air"; no intercooler. The turbo is on the back & the coilpack is in the front. The turbo is mounted a little different than on the G-body; but it is the same engine.

i believe one of the differences is theres no oil return boss for the turbo.

mini hi-jack alert!

Can you make a turbo Riviera fast?

I'm planning/hoping to on mine...
Its got similar weight as a G body,
The trans is a front drive used in the ElDorado/Toronado/Riviera E bodies: a THM325-4L; its basically the same (internally) as the 200R4
& a hot-air 3.8
The exhaust is a joke though, a single little soda-straw pipe!
I'm thinkin' an 3" single shot to open it up & keep it "stock"-ish looking.

Oh that's cool! I always thought they were rwd

 

[rev. 3:11]

The "E" bodies were front wheel drive (Riv/Toro/ElDo)
but the engine is in "normal" front to rear alignment...
kinda weird
