Well I was trying to answer the question that quite a few people asked. The 1.9 HO head on the 2.0 SPI block. Well we all know that they will bolt together but no one actually did it. After assembled I did a compression test even though the motor is on the stand. Cranking it over by hand it showed 130 (+/-) 5 across the board. If I get a chance to actually put it in a car to check the clearance of the intake manifold which should clear with no problems. I just thought while I had time on my hands that I would do something constructive and answer the long sought after question. It seems that the compression is a little higher than the 1.9 spi hybrid motor, if I were to say actual compression I would say between 8:2.1 - 8:5.1 which is still good for turboing. Now if I can get it into a car it will be ran with megasquirt so I wouldnt need a cam sensor. Figure that you would have the full Hemi combustion with the 2.0 displacement which would be the best of both worlds. Just my opinion. I will keep you guys informed when I get it in a car and hook a turbo to it.
