Stacov Posted August 15, 2004 Share Posted August 15, 2004 Ok. First question is their any differences between the black and blue motors? by that i mean one has a black tappet cover and black airfilter cover and the other is blue. Or did Ford feel like a change of colour? hehe ive been told the blue one is meant to be higher compression but im not sure that why im asking and second question is... What would be easier change heads over or big end bearing? Because in my cortina atm me and my oldman are pretty sure one of the valve's have gone its missing hardout and we have check the timing and carb but whatever we do makes no difference. Reason im ask about the big end bearing is because ive got another 2ltr motor sitting their but the big end bearing has gone in it. So just thinking what would be easier keep my current motor and change heads or put in the other motor and put another bigend bearing in ? oh yeah forgot to add we changed the leads and sparkplugs aswell thought i better add that in before someone says check them hehe Quote Link to comment Share on other sites More sharing options...
Jerm Posted August 15, 2004 Share Posted August 15, 2004 umm my cort cam cover is red i think it has been painted though... changing the head is easier in respect that i'm pretty sure you can do it without taking the engine out of the car....

jinx Posted August 15, 2004 Share Posted August 15, 2004 The blue ones were earlier models. May have come in cortinas up to mk4. The black ones were definitely in the mk5 and sierra. The black ones have much better quality head castings. Less casting defects and a much neater finish. Heads are easy to change - I remove mine to fit the engine into the escort, it makes it much easier to fit and is a good time to check the engine over...

Stacov Posted August 15, 2004 Author Share Posted August 15, 2004 ahh.. what about the tappets/cam when you take that off to take the head out do you have to reset the tappets? Just trying to get all the info i need cheers for the help Quote Link to comment Share on other sites More sharing options...
Guest freedz Posted August 15, 2004 Share Posted August 15, 2004 I thought the blue were aussie assembled, and black were german? i dunno ? black were in mk5 though not sure bout any earlier. wonderin if black was english assembled too? Anyone in the know bout this for sure cause ive had many conflicting stories on this matter. I once heard the black ones cylinders are more central in the block and can be bored more again im not sure cause dont the heads interchang? You might be keen to rebuild the engine with the two you have? Make one good one and check all the bottem end and top ittle be a spanker and you wont have anythin to worrie about in future? Also when fitting the mk5 cortina into a mk1 escort did anyone cut their sump and put the oil reservior at the front instead of the back and put the dipstic and pickup at the front so the engine will drop in easy. Cause its a real bugger getting it in at the moment even with the sump mods ive already done. It goes in but its not quick enough I dont want to modify the mounts i want it as far back as possible and low in the bay so im not topheavy.

Pushrod Posted August 16, 2004 Share Posted August 16, 2004 Hmm 2ltrs aint really my thing so i dont know to much about them but the 205 blocks are the best I think like the cossie YB's are I think ill just stick to pre xflows Quote Link to comment Share on other sites More sharing options...
Stacov Posted August 16, 2004 Author Share Posted August 16, 2004 Well it seems ford put some special screws into the top of the motor looks like a star so ill need a star-socket ? Well that's what i was told at the store today but they dont have any instock and they were like you will have to take one out so we can make sure you get the right one. Im like YEAH if i could take it out i wouldnt be looking for that tool so is it called a star-socket ? and they cost much to buy ? Quote Link to comment Share on other sites More sharing options...
Guest Jamezuu Posted August 16, 2004 Share Posted August 16, 2004 Its just a 1/2" allen key socket, Repco and butler sell them for about $10-15. The blue tops are just a earlier version which came in mk2 capri and mk3-4 cortina, black top n the mk5 cortina sierra only difference i can tell like what has already been said the quality of the casting.

BigDave Posted August 17, 2004 Share Posted August 17, 2004 Most good socket seys now come with a full range of Star fittings. Any tool supplier can get you a full set for next to nowt. 200 block is the best by the way. Oh, and Pintos dont have tappets. CheeRS Dave...

The 205 block is the best. It has stronger rods with thicker webs, and thicker cyclinder walls, and generally 5kgs of strengthening. They also feature a oil drain well for those inclined to turbo their model. And no tappets on a Pinto?? well,..don't know what i've been adjusting all these years!

Guest RMinOZ Posted September 11, 2004 Share Posted September 11, 2004 Hiya big guy. RT 200 series block was made for WRC turbo cosworths. They are heaps heavier than a normal pinto block. 205 blocks are nothing special. They are also used in cosworth turbos. BUT cosworth used seleted blocks from the production line. This would be mainly to get the correct bore sizingz for the pistons they would use . As for 205 injection rods [u guys in NZ have them with carbs sierra carbs, I believe].....they are cast as opposed to forged. They would need 3 times the material in them to achieve the same strength as a forged rod. Either way, they are hard pressed to sustain revs over 7500 rpm, either of them. Nice site guys. Keep up the good work! Quote Link to comment Share on other sites More sharing options...
Jerm Posted September 12, 2004 Share Posted September 12, 2004 cheers mate... its good having such well knowleged people on the site.... giving reliable info Quote Link to comment Share on other sites More sharing options...
RT Posted September 12, 2004 Share Posted September 12, 2004 Actually Rminoz, there's been a lot of debate about the 205 cosworth block thing. I was at a engine specialist once who showed me that the cosworth block was in fact different to the 205. The frost plug on the 205 is a lot bigger than the cosworth, he had them side by side. Anyway, yeah I know the 205 rods arn't anything special I wan't comparing them to forged items, but they are better than a standard pinto rod, and if you're using them for a turbo application like mine that doesn't rev over 6,000rpm they're fine.
