Nice work on the engine Doug, shame about the piston - what caused it though? was it pinking? Strangely a friend at work, I think from what he said, has done the same to his car last night! My mate has a Ferrari 355 replica based on a rev 2 MR2 Turbo - quite a quick car, think the rev 3 engine has another 20bhp or so? NIck ps the v4 is looking amazing. :bow: |

I bought the car like this 10 years ago for $300 and it has just been sitting in my back yard waiting for a title, which never came. I finally got a bonded title and started into it as I want to have a little sports car to speed around in with the T-tops out. Pistons arrived, new rings, cylinders honed, valves reseated, engine back together minus the intake and wiring... Did a quick compression check once I got it all timed and sealed up: 200 pounds of compression in the cylinder that was burned. The other 3 were also right there, so it should be a screamer when I get the intake cleaned out and installed. --- Quote from: NickG on April 21, 2011, 02:24:05 PM ---Nice work on the engine Doug, shame about the piston - what caused it though? was it pinking?

NIck ps the v4 is looking amazing. :bow: --- End quote --- This motor has 115hp, the 2.0 liter in the mk2 has 140 n/a and almost 200 turboed. It looks like there was a flaw in the piston from the factory. It burned through in the thickest part of the piston and into the compression ring groove, so it was not pre-ignition. It looks like the previous owner ran it for a while pumpin raw oil straight into the cylinder, then back through the egr into the intake, it is in REALLLLYYYY bad condition inside, so 5 cans of carb cleaner should make it pretty again. On a side note... I am not planning on keeping this motor in this car for very long, maybe just through the summer and fall, then I am looking at putting a 3.0 liter Camry engine in it. About 200 HP out of the box and torque that never ends. Well documented on the inter web and should be dooable for about a $1000 bucks (and fits in, sort of...) Should be a fun winter project... Should be back to the V4 next week... Doug |

Nice work. Over here (I say here but they are all Jap imports) the early mk2 turbos have 220bhp and the latest ones were 240! Must have been slightly de-tuned for the American market. My friend was also considering the camry v6 engine but to get somebody to do it you're talking £3000 over here! |

I think then is when I will do the swap. She is running like a top now, so back to the fun stuff... Doug |

Well done, always a great feeling when it fires back up after major engine work! No reason it shouldn't by there's always that thought at the back of your mind! |
