dylan Posted February 25, 2008 Share Posted February 25, 2008 im looking at rebuilding the old 1600 out of my mk2 cortina to put it into my escort, numbers on the engine block are 691M 6015BA i just wanted to know what this motor is like in comparison to the sport motor that is currently in my escort,im going to do the following port and polish head,mild cam,2L carb,extractors and 2inch exhaust with these in mind which would be the better motor to get power from? cheers Quote Link to comment Share on other sites More sharing options...
Unclejake Posted February 25, 2008 Share Posted February 25, 2008 Much of a muchness really. The Mk2 Cortina engine is going to need bits off your Escort engine (like sump, oil pick-up, dipstick etc.) so you may as well do the Escort motor. Polishing the head = bad (and pretty much impossible with cast iron anyway). What is your budget? Quote Link to comment Share on other sites More sharing options...

Without serious overboring the existing Escort engine will be good for a few extra horsepower without going nuts. Quote Link to comment Share on other sites More sharing options...
d.p.n.s Posted February 25, 2008 Share Posted February 25, 2008 yeh ive heard of 1600 block and 1300 pistons havnt tryed it muself but heard it mentioned a few times. dan Quote Link to comment Share on other sites More sharing options...
dylan Posted February 25, 2008 Author Share Posted February 25, 2008 budget is really small just wanted to get a few new bits and pieces to get the motor running nice the only reason i even mention using the cortina engine is that its already out and sitting on my bench so i could do all new gaskets,oil pump,water pump,thermostat then one weekend swap everything over,also can i get any decent gain out of cleaning the inlet and exhaust ports up with a dremmel Quote Link to comment Share on other sites More sharing options...
Unclejake Posted February 25, 2008 Share Posted February 25, 2008 yeh ive heard of 1600 block and 1300 pistons havnt tryed it muself but heard it mentioned a few times.dan That rasies the compression. To exactly what ratio I don't remember. budget is really small just wanted to get a few new bits and pieces to get the motor running nice the only reason i even mention using the cortina engine is that its already out and sitting on my bench so i could do all new gaskets,oil pump,water pump,thermostat then one weekend swap everything over,also can i get any decent gain out of cleaning the inlet and exhaust ports up with a dremmel Attacking the head with anything but skill is probably just going to make the motor slower. There are zillions of 'ported' heads lying around in sheds for these things and some of them will be choice. To build a firebreathing and strong 1600 crossflow will be in the order of $8k -$12k. A somewhat improved one (fully freshened) can probably be done for about $1.5-$2k if you can find the right bits at the right price. By way of example my NA 1500 pre-crossflow is delivering more than double the original horsepower - but it is an expensive time bomb. Is your existing motor worn out?

dylan Posted February 25, 2008 Author Share Posted February 25, 2008 the engine thats in the escort at the moment is spitting heaps of oil out the top of the rocker cover and is also running like a pile of snot down low but i know the cortina motor was a mint runner when i pulled it out,............around about what sort of money would i be looking at to get the head ported?

Unclejake Posted February 25, 2008 Share Posted February 25, 2008 around about what sort of money would i be looking at to get the head ported? Including big valves and springs I would say $1,500-$2,000 by someone reputable (with a flowbench) Quote Link to comment Share on other sites More sharing options...
two_days_late Posted February 25, 2008 Share Posted February 25, 2008 This is what it cost me for the head work on my 1600 escort motor: Supply & fit hardened inserts x 4 158.00 Strip & clean head 18.00 Bead blast & acid clean head 32.00 Crack test head 24.00 Reface valves 28.00 Reface Seats 38.00 Reface head 40.00 Clean & assy 44.00 Oversize valves 105.00 Port & polish & match to manifolds 200.00 Double Valve Springs 193.00 ============================================ Total $963.33 That was by a place called Chris Carrick Reconditioners. There are photos in my build up page, might find some other interesting info too. //oldschool.co.nz/phpbb/viewtopic.php?t=10637 cheers, Matt Quote Link to comment Share on other sites More sharing options...
petemk1 Posted February 25, 2008 Share Posted February 25, 2008 have a look on turbosport.co.uk heaps of info and they definitley know what they're talking about Quote Link to comment Share on other sites More sharing options...
dylan Posted February 25, 2008 Author Share Posted February 25, 2008 cheers two_days_late that seems a pretty good price,unfortunately im a poor student and dont really have that sort of cash so will probably just look at match porting the inlet and exhaust ports Quote Link to comment Share on other sites More sharing options...
Gaz Posted February 25, 2008 Share Posted February 25, 2008 Why dont ya chuck the cortina engine in the scort as is. Then build a slightly hot one in spare time as budget allows. Quote Link to comment Share on other sites More sharing options...
dylan Posted February 25, 2008 Author Share Posted February 25, 2008 well the plan is just to do these few things and paint the motor up so she looks all good and that way i should have a reliable little car with a bit more power its only really to get me to school and back and any other money i have will go on the cortina Quote Link to comment Share on other sites More sharing options...
MACKAZ Posted February 25, 2008 Share Posted February 25, 2008 Dude I got compressor,die grinder etc to help you out if keen. Quote Link to comment Share on other sites More sharing options...
Gaz Posted February 25, 2008 Share Posted February 25, 2008 There is millions of hours in doing the 1600 head because of the material its made of. I reakon for a little bit more power for cheap do... A cam from snow in Palmy $240 ready to go 32/36 off a cortina etc.. prob free if ya got one lying round. extractors ... already got some??? and if ya can be arsed get the flywheel lightened. Thatd be a bit more powerfull than standard and be pretty cheap to do. Quote Link to comment Share on other sites More sharing options...
dylan Posted February 26, 2008 Author Share Posted February 26, 2008 yup i have the carb and extractors will also be looking into a full 2inch exhaust the engineer at dads work said he would lighten the flywheel for a box of beers aparently the cam in the escort at the moment is a mild one but it must be very mild because ya cant hear a cam at all so miight look into something a bit more lumpy what sort of cam should i be going for?

Unclejake Posted February 26, 2008 Share Posted February 26, 2008 ^ Kent A2 grind. Don't be fooled by a smooth idle. My race car idles smoothly and it has a cam that would smash your standard valve train to glitter in 30 seconds. Lumpy idle with a hot camshaft is a thing of the past Quote Link to comment Share on other sites More sharing options...
