you know doing the 2.5 swap is very simple, if you read up on it (there are tons of how-tos) and got the parts you could easily do it yourself in a weekend with some help.

As for the best shop to go to, the only one that i've talked to that even knew what a klze was, was sunbelt performance in buford. But they only rebuild and do performance upgrades to motors themselves. You could talk to balance performance but you will be paying out the arse.

Your main problem is that according to your signature you have a 95, OBDII to get a 2.5 klze your going to need to find a pre 93-92 and get the guts and wiring harness out of it. because the klze uses 2 ecu kl31/kl36. which are OBDI now you can use a kl68 ecu but this ecu uses a maf instead of a vaf which means your wiring harness still isnt compatable and you would have to get one from japan or australia (damn near impossible).

Another problem Mazda's Auto trannies suck period, people have done 2.5 klze swaps with atx's and well Rip boom kaploosh. They just dont like the amount of power that the motor gives. So a manual tranny would be in your best intrest, Also if you do go manual get an mx-6 transmission they will bolt right up and you'll have a taller 5th gear which will help ya out on the gas.

I recomend going to BJE. I've bought 2 motors from them myself (2.5l Klze and 2.0 Kfze) and they have some of the best motors, and also compression test each motor, and they have 2 month warranty.

If you have any other questions your best bet would be to go to www.atlantamx3.com/mocaforum thats Moca's forum (mx-3 owners club of atlanta) we have the most number of Klze swaps in georgia and possibly the south, we've done over 5 swaps for just the k series motors
