I wonder why they wanted an 1800 bottom end?
That looks like a right old lash up to be fair........I wonder what it runs like, a MEMS 1.6 T16 with a distributor, running in a ZT?.....assuming they've used the MEMS 1.6 ECM, the car will not pass a legitimate emission test, nor will any of the instrumentation in the car work correctly.
if they've used a MEMS 3 (more likely due to the multiplexing requirements of the car), it would be interesting how the ignition is being handled.
You would be better off having a Z&F 200 BHP remap and use the N Series you have hanging about, than fannying on with some dreadful Frankenstein monster like that, beside that, the 600 and XW R8 are far better cars to be fitted with a T16, the ZT doesn't qualify on so many levels.......
