posible swap question

[aguiloco]

Hello, I was a long time thinking about to swap my car to a KLZE, but if I get one of that engines I will replace the pistons and rods for another better. Whats the diference between KLDE an KLZE, only the cylinders and pistons? Would be cheaper for me to buy a KLDE and make that modification to turn it to a KLZE?

Buy a DE, replace the pistons and rods, but it is not a ZE, it is still a DE, just a built DE. It will be cheaper and if you use higher compression pistons it will be just as fast or maybe faster than a ZE.
A DE and ZE are only different in the pistons and intake manifold.

Mmmm so why do some KLDE guys opt for KLZEs?

[Tempus]

well I opted for the DE so like I couldn't tell you.

But perhaps they feel it's easier to just get the ZE engine than buy a DE and then a bunch of parts, labor, time to do the work to change it into a ZE..

( I suspect there's also ECU changes VRIS set point differences, and more than Just pistons and intake when it comes to the differences in the engine.. but I'm far far from a ZE expert. )

I bought a de because parts are easier to find, and eventually i want to go boosted. The lower compression on the de is better for boost. If you are going to run all motor, and messing with the engine internals is not your thing, go ze because its more bang for your buck. Just my .02

really I love the ZE, but as blazeregs says, to get a DE is easyer, because I´m from Spain and maybe I would can see the engine after buy it, importing a ZE I have to hope that the engine is running good, and I will have to put it as soon as posible in the car to test the engine in the guarranty period. To buy a engine that I dont see after makes me worry a lot, but I really want a ZE.

I mean guys that drive probes or mx-6's that already have KLDE's. They do put in KLZE. It must just be easier to do a motor swap then tear apart the engine and drop in new pistons.

does anyone know if its possible to convert a 1.8 to a 1989 3.0 ford probe v6?..its the same basic layout as the mazda engine, just curious if anyone know if it will fit into a mx?

Just cause it fits, doesn't mean it's the same layout. The older Probes/626/Mx-6 used F-Series engines. Mx-3's are deisnged for B and K series. The 1st Gen 88-92 Probe was the only one that had the Vulcan V6 option.

It takes some custom fabrication to get an F-series in an Mx-3, and it's only been done once (that i know of, Bochek's attempting a second one). The Turbo SOHC 2.2L 4cyl F2T actualy makes 145hp and 190ft-lbs of torque. The 3.0L Vulcan V6 actually makes 145hp and only 160ft/lbs of torque. The F2T would have more potential, more power, and it's known possible to fit into an Mx-3, although requires custom work, it would be costly if you needed to pay for someone to do so. Although the F-Series motor and transmissions are probably the best you can get, the Mazda B-Series aren't far behind and have alot of potential as well, and have the benefit of being a newer motor. A BPT, although requiring a RS doner car for parts, is (for what i know) just a complicated bolt-in, only because of the GS-to-RS conversion in the engine bay, but bolt-in none the less, because the Mx-3 was designed to accept those motors.

In comparison, the drop-and-plug KLDE makes 165hp and 165ft-lbs of tq, and the drop-and-plug KLZE makes 198hp and 165ft-lbs of tq. As well, that Vulcan 3.0L is an older engine, so they will be of higher millage, and parts will be alot more scarse. I'm not sure about support, but there's alot of KL's out there, could even swap the internals of a DE and ZE, and the exterior components of the K8 & KF, so parts are plentiful.
