After doing much research, I'm coming to the conclusion that parts for the 1.8L are more numerous than for the measly 1.5L.

Now, this is my question. Would it be a good idea/feasible for me to change my 1.5L into a 1.8L, ie bore it out, change the pistons, etc., or would it be better to go to a junkyard or something of that nature, buy a 1.8L engine and install it. Now, I realize there are other factors at stake here, including changing the computer and/or other parts controlled by the comp. Is all this more trouble/expense than it's worth?

Any help or advice you guys could give me would be great. Also, I'm in the SoCal area so if there's any place you could recommend I could go to find my answers and/or parts, that would be helpful as well.

Thanx!

yeah it would be cheaper , to get the 1.8 than to bore the 1.5 , I know there is a kit for th emiata that cost about 3 grand , that bores there 1.6 to about a 1.9 . wich would put a 1.5 to about 1.8 , but the price plus labour , lol ,,,..........
know a swap to a 1.8L
you need the comp,axles,engine mouts,tranny,engine,gauges,and some other minor items in the engine bay may also be needed

Bruce, so does that mean I'm going to have to get the complete specs for my car, and compare the two or what? I'm sure this doesn't happen too often but I'm not sure what else to do. Maybe I'm getting a little too anxious or ahead of myself, but I'm also getting frustrated at the roadblocks I'm experiencing here. I guess I'm not really understanding what all needs to be involved.



And is all this really feasible? Have you ever heard of something like this happening with some success?

ofcourse you could also get the complete head package from Gude if you did not want to swap your engine out, .. Also if you are going to be paying someone to do the engine swap for you labour is another bill you will have to take in mind, cause it will be quite a few hours to get the work done, but if you have time patience and good mechanical skills you can do the swap your self , the 2nd gen , is a really good platform also , so if you get some power under the hood , it has the handling to back it up ...

You will basically have to decide what is best for you to do , cause no matter what you do , it will cost ya some money . Me personally I was looking at finding a crashed 1.8 es Protege and swapping everything out of the car, from the computer to the axles,
A crashed 1.8 can be had for about a grand if you can find one, The good thing about the 1.5L is that there were so many of them sold that if you do blow the engine then replacement parts are easy as hell to find, The 1.8 on the other hand ,, .. you get my drift ....

The same reason a Jun 1.8L stroker kit for a B16 wont fit your 1.5L Z series. Totally different engine series. :shrug:

Bruce95fmla

ok thanks , keep in mind I was asking only cause I did not suggest it would work I only ment that in relation it would turn a 1.5 would turn to a 1.8...
But it was nice to see why it would not work ..
Bruce

Bruce95fmla

I never said anything of a B16 stroker kit , and isn't that a Honda engine ,,, damn I aint stupid you know
Bruce

Bruce95fmla

I still don't see the relevance jesse , as I have never thought of using a B16 upgrade in a Z5 , I understand ur point though

The point is, its an entirely different engine series. Different bore spacing, different journal width and diameter, et al. It wont fit y0!

BLT has turbo maifolds for the 1.5L. If you can install the system yourself you could tubo charge the 1.5l for around $1500.00. As soon as BLT @ http://blt.n3.net gets the the group buy on the 1.6L manifolds done I paln installing a turbo on my 1.6L.

SDRob

So how hard would it be to install the turbo manifold, and/or how much would labor be if I had someone else do it? How about changing the headers, any ideas on that? After spending my entire work shift (that's the Navy for ya )) looking up stuff, I finally found that Ractive makes an air intake for the 1.5L. Everyone else seems to have to custom theirs, so maybe that'll help some people out.

By the way, much thanx to all you guys for helping me out with this. I know where to go for the expertise.

Any ideas where I can find Mazda-specific parts, like a warehouse or something, or am I going to have to go to a junkyard if I want to do the engine swap?
