Complete newbie to mx3's 1.8 V6 se on its way :)
-
it is a stock engine so hope it will beat an st24. got a friend that has one. according to the book it tops out at 133mph and the st tops out at 137. can anyone veryfy that 133 is the top speed for a stock 1.8 V6? i guess power to weight ratio would make the mazda quicker as mondeo is nearly 2 ton. mazda is 1140kg apparently :D

**The ST24 weighs just over 1.3 tonnes, while the MX-3 is 1.1 tonnes. On paper, the ST has the edge with power to weight - by a fraction. But it's long-geared (same as the Probe and MX-6) and, though torquier, has a peaky torque curve. It's slower to 60mph, a quarter-mile and 100mph. Anything with bends in favours the MX-3 unless the bends are very shallow and fast, where the Mondeo's longer wheelbase and lower polar moment will help it.
In theory, the MX-3 is aero limited (the air pressure in front of it exceeds the power it generates' ability to overcome it) to 141mph. Crunching the numbers, on the stock 15" wheels it's also gear limited (maximum engine speed in the longest gear) to 141mph. Disregard what the speedometer tells you - speedos are legally allowed up to a 10% overread and are not necessarily accurate at any speed.
Not familiar with sunroofs (or rather moonroofs - sunroof is glass, moonroof is a body panel) failing but a fuse would be the first place to check.**

oh yeah i just double checked. mx3 will have approx 122hp/per ton. st is 130 something lol. so would it be possible to squeeze a V6 probe engine in or would it need a completeley new loom ecu and all the other gismo's?
-
Yes, the V6 Probe engine (commonly referred to as "KL-DE") fits just fine - same engine as the V6 MX-6. The preferred swap for the V6 though is to put in the Japanese MX-6's V6 (commonly referred to as "KL-ZE"). There's many, many threads about this - I think the site admin has just put up a post in the How To section about engine swaps.
-
think i would go for the probe as there is a few in the breakers down here. is it possible to get an ecu remap in the mean time though? like i said i know its a baby V6 and dont wanna damage it
-
Fair enough, but the Probe V6 is only another 30hp (135ish to 165ish) and for the amount of effort not really worth it. The Japanese MX-6 packs another 30hp on top of that…

my mums got a mondeo 2.5 v6 duratec and i hate driving it. too heavy, too much roll and the power seems all wrong, plus it doesn't rev as happily as a my 3
-
I have driven an ST24 and thought the power was pretty good but at that time i only had a 2.0 zetec to compare it to. the power of the mx seems about the same as the st with better fuel econamy and it does feel alot lighter and alot more "chuckable" into corners. the mx defo feels alot stiffer in the suspension department. even though the st has sports suspension it is longer wheel based which would make it very rolly.
one week to go before i pick it up :D insurance is all sorted, will be driving it strait to the post office to tax it and then to the petrol station, brim it full of petrol then off for a nice long drive with the misses :D
-
There is a KLZE for sale on here at the moment for £300 with haggle room and that will give you 200 bhp.
He also has the ecu that you need for the swap.
-
I would love to but still trying to scrape enough to pay off the car lol. one day in the near future i will probably be looking for an engine swap. Thanks
