VG20ET any intel?

[leonelrr]

My friend bought this engine thinking it was a VG30ET as a replacement for his z31. Well it ended up that is a VG20ET, very similar to the VG30ET except it is 2.0 liters not 3.0.The dimensions are almost the same except for the lower intake manifold is smaller. The heads are closer to each other..

We managed to swap it into the Z31, we ran into a few issues mostly clearance issues.. The exhaust manifolds from the VG30ET didn't quite fit on the VG20.. We used the intake plenum from the z31, and it is now running.. But we would like to get more information from this engine, it seems to be very rare..

This is what wikipedia says about it..

" From wikipedia.com"

VG20ET

The VG20ET is the same as the VG20E, but with turbocharger. The VG20ET produces 170 hp (130 kW). VG20ET - This SOHC motor debuted at the same time as the VG20E. Also coming with the Y30, this motor was known as the "Jet Turbo", and came with the Leopard models XS, and XS-II Grand Selection. Contrary to the VG30ET that came out in the US, the VG20ET came with an intercooler to push the horsepower output to 155 hp (116 kW), a great jump from the normally aspirated VG20E. The turbo included with the VG20ET had two different settings. At low speeds, the turbo's flap (wastegate?) would stay closed improving the response at low RPMS. At high speeds, the flap would stay open, decreasing resistance and increasing exhaust flow. At its maximum flow, the flap would open at an angle of 27-degrees, while the A/R ranged from 0.21 ~ 0.77. Being that the VG20ET had a short stroke (78x69.7mm), it was thought to have insufficient low end torque. Nevertheless, the VG20ET was a great improvement over the VG20E.

It was used in the following vehicles:

* Nissan 200Z (Z31) * Nissan 200ZG (Z31) * Nissan Laurel Medallist (C32)

Any input will be highly appreciated..

I would see if you can track down a Laurel, Leopard, or 200z factory service manual. Any of those would likely have a good amount of info on the motor.
