It's the same motor that used to be in my old 1990 Beretta GTZ. 2.3-liter, 4-cylinders, 180HP/160ft-lbs TQ. All of this in a 2800-lb car.

Here's what it looks like:


It also had direct-ignition, or DIS (Distributorless Ignition System).

I have NO idea how this motor died-out, and why it didn't pass-on to the Beretta's spiritual successor, the Cavalier. Cav Z24's had a version of the QUAD, but it only put-out 150HP/150TQ.

Anyhow, here's a dyno-graph of a stock GTZ:

Hope you realize that this motor came-out in 1988. From CHEVROLET.

Wow....what made for such high output? I mean 2.3 liters is alot, but still-high com. ratio or something?

High compression with relatively high revs.

It would be to much of a pain, id have to switch to OBDI, then id probably lose my power steering and it wouldnt really be worth it. Im going to make my LD9 an HO (kinda), doing the HO manifold swap, going to put on an intake came from a 95 quad, and exhuast cam from a 90-94 quad. for about $200 that isnt bad, and ill probably run a mid to low 15 1/4 mile. compared to a mid to low 16. But really the LD9 is still a quad4 GM just changed the name to TWIN CAM.

Yeah, you're right. Does the LD9 have that power-robbing balance-shaft also?

I know some buildups for a Cav Z24 include removing that balance-shaft, which in essence restores the 30-or-so HP that it robbed rom the motor's HO configuration.

Yea, it has that on it I believe.
