KL-ZE or BPT is better for MX-3 ?!

well i used the search engine but didn`t find anything But I am almost sure you have already discussed this very important subject.

I also want to know which is harder to swap?

regards to all

Ok, firstly it depends on your starting point, V6 or 4cyl
the easiest swap is a KLZE into a V6 MX-3, but if you have a 4cyl then a BPT is the way to go

you can mix and match, but things get alot more complicated

As I can see maybe i wasn`t right supposing you might discussed already this "problem".

Wel I know that for the V6 Kl-ZE is better and for 4 Cyl BPT but I want to know which is better... which motor is better to swap because I am wondering to get 4cyl (107ps) or to buy another V6... ?

This is an arguement that could go on forever. Everyone has their own taste. Personally I want a klze but many here like a bp-t instead. It's all on you. Each motor has it's pro's an con's. the bp-t handles boost very well, but in my opinion the klze is meaner outta the box. Each can be built to be faster than the other, it's all personal preference. With time and money you could build a b6 to be better than either the bp-t or klze. We've seen it done. So the choice is yours alone

The problem with boost.. ok.. this is an outside observation. I am sure that there will be a LOT of people that will disagree with me.. especially people living in denial

But it seems once people start boosting their engine.. they dont know when to say "Good enough" They always want more.. they keep pushing it and pushing it till eventually.. BOOM.

So my advice here will basically be a reflection of what your wallet can handle. If you want to go boost.. go all the way.. do it right the first time. Build the engine to handle tons of boost right off the bat.. that way you will save money on the engine in the long run. There are more than a few good examples of people on this board that have built or are building good BPT engines (even one or two B6T's too) But if you start off stock.. your probably gonna end up with a blown motor unless you can just say "enough" before its too late. And make sure you get a decent stand alone control system too.. dont mess around with stock ECU's unless you just want a stock BPT. (Again we come back too.. is that going to be "Good Enough")

Now if you just want a nice extra HP gain out of the box.. The KLZE does very nicely. If your in a GS car.. its not difficult to swap in either engine into your ride. If your in a RS car.. putting the ZE into it will be a LOT of work. Doesnt mean it cant be done.. but you will end up swapping more than just the engine or tranny if you want to go V6. Suspension will be an issue and other parts like the radiator, AC components if you have AC and want to keep it (Like the condensor).. Power Steering.. Alternator (not a big issue but still is one).. etc.. So in a RS.. the BPT is a bit more of a bolt in job.. your still modding things for the turbo a bit.. but most of it is still bolt in and plug n play. More electrical issues than anything else.. but you will deal with that in a GS car too.

Just my 2 pennies worth

So what I finnally can make in conclusion is that the GS version is better... asking me why?
Well GS is younger than GS and the infront board is more beautiful than the one from RS. As you said... the BTP is plug n play swapping just to change few of electronics...

So am i right ? And the performance according to me is again easier to tune.. what I mean is that its easier ti find for example bigger turbo to put.. but it`s mine non-professional thoughts

I don't know am i asking in the right place, if not, sorry :roll:

I heard, that KL-ZE doesn't work with turbo well, it can't stand higher pressures :roll: is it true ?

Yes...., and no

You can't run high psi on a KLZE, but then again, you don't need to. what you lack in boost pressure is made up for in higher standard compression.

Aside from money being a issue here. I think your personal experience level should play a huge part. If you have never swapped a motor before and or worked on cars much. I would go with the klze cause it is the easiest motor swap around in my opinion. Adding boost and tuning it properly is not for the average joe. If you want to learn as you go, i say get a gs and do the klze swap. I am guessing by the way you stated your question, you are new to cars. No offense, but most would do alot of research instead of asking such a broad question. If i am wrong and you have tons of experience, than it all depends on your preferences.

let's not forget the GS models have a tighter turning radius...

mazdachad · Post by **mazdachad** » October 2nd, 2007, 6:39 pm

thats why you need to put a bpt in a gs. imo best of both worlds

I thought they did too, but apparantly they don't. The GS steering wheel turns less times than the RS from lock to lock. But the turning radius is the same.

However, that brochure also says that the GS has rear drums, which it clearly doesn't.

No matter what The GS has you can always put it on the RS. I have almost all the extra parts that are performance on my RS that you can get on the GS. Just need front sway and steering rack.

Good call... I never realized the radius was the same, it's just the turns it takes to make the turn... 3.1 vs 2.7...... hmmmm

So what exactly does that mean? the steering is tighter??
