It's Mazda time !!! I need input like Johnny 5! Lol

[Ze-86]

Hello to all the Mazda lovers! Well this is the 2nd forum club I joined ...hope I find what I'm lookin for well I'm planning to build a crazy REV HAPPY k8ze engine bore,port n polish,custom : cams,rods,pistons,slightly knife edge crank,dry sump and the works...I know it will take a while but I'm ready to dump the monies n have fun ! There is a couple things I need help with I have searched and found alot of answers but the following are not clarified or known to me thus far, soooo.....with all that said this is what I need to know...
1) are there any arp studs/bolts for k8de/ze? (found some for klze not sure if k8ze and klze are the same)
2)does the klze head fit the k8ze block? (just checking ... A bigger head that can be modded would be great!)
And for those true mazda lovers ... 3) are there any RWD bell housings that bolt up to the k8ze Block?
Thanx in advance for any Answers!

Welcome to the forums. By simply Googling there is a lot of great info out there, like this. http://www.mazda626.net/topic/37114-kld ... 4-vs-klze/ or this http://en.wikipedia.org/wiki/Mazda_K_engine

MX-3 MX-6 and Ford Probe all share similar drive trains so lots of info on any of these forums. Generally speaking trying to mod a K8 is a waste of time and money. Simply drop in a KLDE 165hp or a KLZE 195hp and your done.

ARP head stud kit is part number 218-4704

rod bolts... I think we're still SOL.


Dan is right, building a K8 is a waste of money, unless you're trying to be 'different'. Nobody makes s--- for it, it'll all be custom. So unless you enjoy the idea of spending $2000 on one-off pistons, if you can find a company that will do it, don't think too much more on it.

yes in deed,ive been all thru google saw those pages and yes i want to build the k8 reason being its a very small v6 ...small liter engines easier to rev (stroke/crank, nearly a 1:1/squared engine, like farrari 2.0 v8) and is perfect for what i want to do and the engine sounds great... kl is 2.5 v6 so are many v6s, boring... heavier internals so they wont get all the rev they can get like the k8 can... i want to do somthing different any one can get a big engine and turbo it,been there done that on to new things...how bout an n/a engine with near 300/400 hp and have immediate power at the flick of the throttle...no one knows what the k8 is capable of cuz no one fully built it Yet many knock on it ... and from what ive seen/heard all thats done is basic bolt ons, internals, and turbo/super charger, theres more things that can be done to gain power, besides im after rev and a sweet sound any engine with heavy mods will make power n my car weighs 2100 w/driver so anything above 250hp with the sound of a farrari would do great and thats a fully built k8 ... and for pricing i hhave a hand full of guys i can haggle for discounts ... besides anything is possible in the custom world n thats were i live! any who, for the tranny i asked about a RWD tranny ...like any trucks or the rx7s for example, is there any RWD tranny that bolts up? @ ryan thanx for the part number!

[Daninski]

Like Ryan said, no after market parts. Pistons, piston rods and what ever else. If you plan to up an engine's power you need internals that can handle the additional power being produced or your just pi**ing your money away. Josh did an AWD, this post may help you. http://www.mx-3.com/phpBB3/viewtopic.ph ... hilit=josh

For any RWD setup you need to fabricate an adapter plate, like cody is doing...

Yea I found all the custom companies I needed except for knife edging and a couple other things but I'll find them, just needed to know those couple things for now...this is not my first build, By far, just my first k- series ! I was ready to make a custom bellhousing just needed to check if anything else would bolt on before I did. (fabbed a 4agze /7mgte rwd tranny before and I asked cuz alot of Toyota parts are Interchangeable between many vehicles) just to mention, this setup (k8ze/13b 93+ tranny) is going in an 86 corolla coupe with 240 sx suspension with r34 diff... this whole car is custom ! Mite throw on a rotrax silent supercharger, well see how I feel come internals ordering time....Can't wait to start, to finish its better to build the k8 ($350) than get a 2.0 fararri f355 engine $25,000 lol ! Well thanx for linx guys !

[Ze-86]

Oh just noticed no one mentioned anything about the heads ... does the klze heads fit the k8ze block by chance ??

[Nd4SpdSe]

Very nice and very well done!

[Ryan]

I would think that is would physically fit, but the bore is off by 9.5mm. also, the valves are different sizes, so the reliefs in the K8 piston top will not be large enough for the KL valves. Also, of couse, there's a good chance the oil and coolant passages won't line up very well.

Let me direct you into the direction of a HIGH REVVING KL-ZE

http://www.youtube.com/user/leo3230#p/u/4/a00v0xPPp1c

Apparently the "freakin' Rican's" know how to do it. First Rafi, now Leo, that guy pegs about 10k revs, and a 11.2 1/4 mile time!

You'll NOT find a better built NA K series engine, I'm all for you building up the K8, but just setting your expectations, they WILL be lower than the KL. Ask the Ford Probe guys, too. They live and breathe K series engines.

[Ze-86]

I'm glad u guys like the setup and I appreciate all the help ... and it's funny u mention "ricans" cuz I'm one guess we love the rev lol .... 10k kl nice I'll look into it thanx alot!

[RS_OBD'oh_2]

it seems like a lot of work to end up with one of the slower AE86s out there. 3sgte and sr20det swaps are better, easier and cheaper. I understand doing things a little differently. The K8 is more like the mutaded dog-boy that people would keep in the attic and not talk about in public.

[Ze-86]

yea i know what u mean i have the 4agze 1.6 supercharged engine in as of right now ...i attempted the 3sgte swap but never got to it,thot off the 3 rotor and 4 rotor but i gotta rebuild them every year due to huge ports that leak over time! i could just drop a 1j/2j and make 800hp ..even my lil 4agze can make over 400hp turbo but i really want that sound... even tried getting into a custom pnuematic valve spring setup, to expensive, if u can even find the setup, and u gota maintain it 24/7... i know it kinda seems dumb but as stated above, i want that farrari 2.0 v8 f355 sound,similar to the f1 sound and these k series engine are the cheapest,closest thing that sounds like one that i can actualy maintain,(f355 $110 oil change/$5k tune up every 2-3 yrs is to much) its bad enough finding parts for this old rare car lol! But yea point is im not a very wealthy man i can only do what i can do and at the end of the day that guy with the 1j/2j or crazy v8 lover with AE86 body will be running 8s 1/4 mile or faster, but ill be enjoying that sweet sound that seems like its never gona end (rpms climbing)plus this is my toy, shes doesnt have to be any faster than 10s .... if i had the money id be in a carrea gt or of course that f355...what can i say i just love revvy engines!!!

You should check out Boosted Rafi, he did a FE3 MX-3 boosted. Not a swap that you wanna perform, but still, it's a good part of MX-3 history that should never be forgotten.
