3.1 transplant intoz34?


Recommended Posts

Hey all,

Please save your comments, I really only need technical advice. I have 2 z34s...one 5speed, bad motor...one auto, excellent creampuff of a motor. I also have a Indy Beretta , bad body...with an excellent, strong, lo mile 3.1 and 282 getrag. I wanna put the 3.4 from the auto into the 5 speed car...no sweat. Then, I want to put the Beretta drivetrain into the auto z34.

What do i need as far as motor mounts and cv axles for this swap? I have a complete drivetrain and harness/ecm...all that stuff.

I guess if anyone has motor mounts(brackets) and a clutch pedal, I can buy the cv axles...the shift assy./hydraulic clutch should all work as well...right?Thanks for any and all advice.

well.

 

the 3.4 harness from the z34 will work with the 3.1, some wires just need moved around a little. you just need to modify the auto trans plug for the proper wiring for the 282. and then toss in a 3.1/282 computer for a w-body. get w-specific axles and engine mounts/trans mount. w-body specific 3.1 downpipe. should be able to work with the beretta shifter and cables.

completely unrelated, but how rare are those berreta indy cars? I just saw one in my junkyard...

The non-pace car ones are semi rare, but not really that great, just a 2.8l in them or something. There are only two I think actual pace-car beretta's. I wanna say there are 500 replicas.

Remember that the 3.4 will be a tight squeeze in that engine bay. Do maintenace like spark plugs and stuff before you put it in, just to save headaches later.

keep us posted!! i'd like to see a 3.1/282 in a Z34!!

 

 

IIRC the Beretta Indy's production numbers are something like this...

Green=2500

Yellow=500

Yeh, the Berette indy was a 1990 only optoin, i've had 2 of them, one teal and one yellow. both 5 speeds. They came with a 3.1 only.I am parting out the teal one...this is the donor motor and trans. There were about 6 convertibles (3 indy's)and 3 or 4 hardtop teal hardtops produced for the race...they had 3.4 (stroked, punched 3.1 block)pushrod engines, with custom intake/exhaust/internals...producing about 240 horsies from some specs...very rare and very cool. There were 1500 yello replicas, and 3500 teal ones, all hardtops.

BTW, mihela816, i'm putting a 3.1 in a z34 bay, not the reverse...thanx...

I bet this car still smokes, the torque numbers are pretty high on the 3.1.
