klze 2.5 v6 with out power, like a 4cyl would kill me ..HELP
well here is the story i bought a 92 mx3 from some guy for 500 i later found out that it had the 2.5 v6 klze in it, i did my research and found out i had a pretty sick ride. so i did all the body work, completly re did the interior from a 95 painted it and sent it to the shop for safety. i get back a list a page long like little stuff i knew about, but the car is sooo slow. i thought it might be the cat because the car has 383 *** on it {i re did the exaust up to the cat with a greddy exaust} the engine purrrs fires up fist shot idls at around 5wich might be a little low. i changed the plugs and wires and the plugs were gaped at 5and a bit which im sure is to big. i need help is it my timing?, the cat ?i need sugestions baddly because im about to blow it up and clame insurance...lol thx everyone

Good suggestions above. Also, check for codes. Ten and ground in the diag. box with a test light, it will blink, you record the blinks and tell us what is sais. More info on pulling codes on a ZE can be found with a search.

well the ecu that is there is from the 1.8 v6 i have another spare lieing around that i pulled out of a newer 1.8 but do i need a different one for the klze ?
also there isn't any smoke comming formt he exaust and it has real goood pressure , it is really loud tho but it could just be the tip. the cat does have 383694km on it could that be it.?

As for ECU's, if you have a ZE then you may want to run a KL31 or KL36 ecu (there are some on eBay right now) or a chipped K8 ecu. A KLDE ecu and KLDE VAF may also work. Yea your cat could be clogged as well, that could slow you down abit, I see your from Toronto so I dont think you can run without one. But if you have a loud exhaust with all the cats and mufflers in then the cat is probably clogged. What kind of fuel mileage are you getting?Ryzer02 wrote:well the ecu that is there is from the 1.8 v6 i have another spare lieing around that i pulled out of a newer 1.8 but do i need a different one for the klze ?

There are tons of MXers in Canada. Get together with some of them and let them take a look at your car. It is much easier to diagnose problems first hand rather than over the internet.

same thing happened to a buddy of mine.. His car had a bigger motor swapped in, but his acceloration slowed down.. We messed for hours and hours.. checked wiring over and over.. tried to find it.. no luck what so ever...
Gave up..
Next day, started again, and finally found out it was the timing out only by one tooth on the cam pullies.. Changed it and suddenly had tons of power..
G' Luck.

thankx alot everyone u have been much help it was running a kl01 computer abd u had a spare k8 hanging around so i threw it in and i felt a difference but its still not enough forsure this thing should fly and it still feels slow im goign to check the timing tomorrow because i hope that is it but to awnser ur questions yes my rear passanger caliper were siezed and the wheel bearing was shot so i changed and replaced all the pads and rotors now i don't feel a large slow down when i shift in to N i have changed the airfilter my plugs and wires are fine i think its my timing.
two more question tho do i have to chip my k8 or will it run fine with out it chipped , and after i changed my computer the idle dedided to rev its self to 1500 when i start it but after it warms up every thing is gravy{ anyone know what the deal with that is}

yeah man you need your k8 ecu chipped or replaceing with the kl31 or 36 ecu. or else you wont get the proper performance from your engine, proper airflow, gas etc.... so yeah..
93 ZE curve neck, kl36 ecu, apex lowring springs tokico struts front and rear upper strut bars and a CAI.. still building!!
