My 2002 KLZE Protege 5, kl to kj swap thread

[Damkid]

It's a 98'.... It acts up like that at different rpm range, plus it didn't do it in the millennia so I doubt its a factory rev limiter

[DeeAOne]

Thing sounds awesome man. Love it!

[DuRWooD]

Sounds like a sensor issue. Maybe a bad ground.

[mx-3_4evr]

This is bad ass! I just bought a yellow 03 p5, this might be a good swap once my fs engine decides to take a dump lol!

factory rev limiter. when in park you cant rev that high. thats what it sounds like to me

[Damkid]

On a fresh start up, the first rev can go as high as I let it, so I highly doubt it's a factory rev limiter, but I could be wrong

[MD323]

check all the grounds, sounds alot like the issues we have in the MS world with bad grounds and voltage flyback

[Damkid]

I'll check the grounds although i'm pretty certain they are ok.... tomorrow i'll put some gas in it, and check out a few things with the wiring and go from there

Oh, i forgot to post these pics i took today in the daylight when i backed the P5 out of the garage lol nothing that hasn't been posted before just better lighting lol

im not at all familiar with these motors but you could try disconnecting the maf to check if the engine is able to rev up without hitting that limiter while it is disconnected, though you will probably have to give it some gas just to keep it from stalling if there is no maf hooked up. just an idea as they are known to get dirty/damaged. dirty/damaged parts and poor grounds are the best places to start. also check vac and spark plugs/wires. sounds cool!

Just read through this whole worklog... pretty awesome had a klze in this and even more awesome that you just put a KJ in it! I've always thought that motor was one of the most unique motors mazda has put in a car.

[Damkid]

I think they are very unique as well, its why i wanted to work with one lol

With the MAF not hooked up, it wont even run, i need to check the voltage at the MAF though to make sure it is working properly, otherwise i'm running out of ideas to try but i'm sure i'll come up with something, even if that means megasquirt lol

[progt91]

looking good. glad to see its together. im sure in due time you will figure it out. btw that engine bay looks soo much better in black.

[crazycanadian]

Before you get to involved in diagnosing it just get the car all finished up and ready to drive... Then you can test drive it and see if the limiter is really there or not...

[Damkid]

The only thing left to do is hook up the heater core hoses and fill it up with coolant

I've been thinking that this problem is very similar to how my festiva acted when I first got the kl running with no coolant temp sensor, I'm wandering if the KJ is acting up simply because there is no coolant in it, that's the next thing I'll be looking into

[nerd racing]

^^ sounds like the problem to me. K-series don't like to run without coolant in them.
