90 degree V4 OHC
NickG:
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?

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.

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...

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!

Yea, the ole US EPA makes us throw on all this smog reducing crappola to help the air. the really nice thing about this car is that in 2 years it will be considered an antique and not have to be inspected... I think then is when I will do the swap.
She is running like a top now, so back to the fun stuff...

NickG:
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!
