    the svt didn't have zetec heads. They were cosworth tuned units

    I'm pretty sure it is part of the Zetec family with a Cosworth head.

    "The SVT Focus powertrain starts with a 2.0-liter Zetec Ford engine. In standard Focus models it produces 130 hp at 5,300 rpm and 135 lb.-ft. of torque at 4,500 rpm. This engines cast-iron block already has the strength, rigidity and durability necessary for the increased power SVT engineers were developing.

    Component changes in the block include new forged-steel connecting rods with 20mm wrist pins and lightweight, cast-aluminum pistons. The new pistons increase compression from the Zetecs 9.6:1 ratio to 10.2:1 in the SVT Focus.

    A new casting for the aluminum cylinder head has enlarged intake ports for increased flow. The intake valves measure 33.5mm in diameter, 1.5mm larger than those in a standard Zetec.

    Intake and exhaust valve springs are stiffer by 27 percent and 19 percent, respectively, compared with the Zetec I-4s. That allows the engines redline to rise from 6,750 to 7,200 rpm.

    The intake camshaft is equipped with an electro-mechanical control mechanism, which allows the cams maximum opening point, relative to crankshaft degrees, to be varied between 85 and 145 degrees after top-dead-center on the intake stroke. The variability is dependent on engine speed and load, and is accomplished by changing oil pressure on either side of a piston in a helix between the cam and its drive pulley. This is the first application of variable intake cam timing at Ford in North America, and is a significant contributor to the engines remarkable low-end torque.

    The other significant contributor to low-speed torque is the SVT Focus dual-stage intake manifold, the first application of this technology at Ford. This device is designed to direct the intake air through four long runners below 6,000 rpm. Above 6,000 rpm, the manifold switches position to shorten the runners length, which improves peak power output"​

    Which is exactly what I just said. Didnt use Zetec Heads

    They're cosworth units. Going to be in a pretty high state of tune in the first place.

    Ford's cyclone 3.5L V6 they use in the Taurus, F150, and quite a few other cars (along with Mazda) can be easily tuned for 30hp/70ft-lb of torque with a stage one tune. 70ft-lb of torque with a simple tune. :eek:

    Exhaust side cleaned up, really satisfying getting the thick layer of oil buildup off..

    For the stock valve springs and retainers sure it's pretty close, but you get some super tech duel springs with some crower chromoly retainers and you can get hotter cams for sure.
    This is an example of a stock type s with only a good dyno tune. Notice how he reks pretty much everybody and notice how when he hits second gear just hard enough he pretty much spins till 3rd. The car has an intake and exhaust but the fact that he didn't just use a base map shows the real story. IT'S ALL ABOUT THE TUNE.
    EDIT: the 94 to 2001 Integra gsr also used a variable length intake but I took the butterflies out when I had the gsr in my civic. If you didn't have the correct ecu they would not actuate. Another thing about cams, if your intake and or intake manifold and your header and exhaust is holding you back cams won't help. Stock Honda manifolds are particularly decent but trust me you throw an after marked intake manifold and header on it with cams and it will flow more. Cams should always be the last breathing mod you do.

    Saw our previous car again (the dark gray Seat Exeo ST). I guess it's been sold now because it was for sale for almost a full year even though it was really clean with only ~50k kilometers.

    I'm pretty sure I just saw a Skoda Felicia Fun going down the road...
    It was definitely yellow. It even had a bed cover on it.

    Taking the time to grind back the horrible casting marks on the intake manifold too.

    Why are 4X4s starting to look soccer mum-SUV-ish? The Patrol was once a manly vehicle, like an old Land Cruiser.

    The 1990 Nissan 300ZX costs under $10,000, to my surprise
    I would've thought that it would go for atleast $30,000, but no, under $10,000
    The 90's Miata's can be bought under $5,000 if someone wants one that just runs and drives
    The 240SX's, however, not surprisingly, can go for under $5,000

    Where do you live? That's ridiculous.. You can pick up a reasonably tidy one here for $1500 USD.

    And I've seen 300ZX's go for as low as $2000 USD, even less for one that's not registered :cool:

    They still sell the Y61 as a Patrol Safari with a V6 over here along with this thing.

    First ones are a bit rice, but I still somehow like them. The second ones are a little bit more traditional, a little bit more "bad dude". In the end, I'm going to have to agree with everyone else and say the second ones are better.
