Improving the N/A aspects of the KL-ZE

[Demanius]

Ok, im a crazy man

I want to my kL-Ze to rev to 8000rpm cut out, it revs to 7200 rpm so far

220 kw to 240 kw AT THE ENGINE.

i need info on forgies, valve springs etc

3000 dollars u reckon or more?

i want to have the craziest mazda N/A kl-ze in australia.


thanks guys! lol :P

what companies can i call?

[Demanius]

8000 dollars at croydon racing developments.

mmmmmmm, my god lol

crazy lol

revving to 8500 rpm, thats off the dial, omg. im a dreamer and stupid boy wanting to do this.

[Demanius]

sorry for posting this crap lol.

but is there any mild kits for 1500 bucks or something like that??

[Demanius]

got it sorted, anotha engine, full race spec to 9000 rpm. ill get one in bad condition with the block still good.

saying is one thing, doing it is anotha. i plan to do it

[Pattax]

KL-ZE NA @ 200KW? I'm not sure if that's do-able.

not atw, fly maybe? But the cost will far, far outweigh the build .

From an earlier post on one of your threads a member stated the FE engine in fact puts out 50hp/kw? less than the KL. If this is the case, I'd be looking further into it Demanius. You do realise you will need the ECU chipped/flashed? Imo, @ the hp your after you'll probably need to go stand alone if there are no chips available = $$$'s. You could find a 2nd hand one on fl.com but it'll need to be tuned to the FE engine etc......

just trying to head you in the right direction before you fall into a pit, money pit that is

[Demanius]

yeh naughty, i plan a stand alone computer. it needs to be 8500 to 9000rpm. its possible 220 to hopefully 240 kw at the engine.


is boosted batman still on this great forum? i wish i could talk to him. ffs lol

Rupewrecht may be able to help you on this.......I would've suggested try MX6.com for him but...er.....I don't think they'd be too willing to help you nowdays I'm afraid

[Rupewrecht]

Nah, Pete has been gone for ages.

[marcs_sp20]

He sold most of his engine stuff early last year....

[Demanius]

Ah crap, ye rupey will help. this is confirmed no turning back. big plans no change of mind.

well, make sure if you see stuff for sale 2nd hand (even if it's unused)......you TRUST who is selling the stuff! Um......as a matter of fact, I'm still awaiting some er.....engine stuff FROM early last year from a particular member

[Pattax]

can you list your plans to achieve 200KW+? I don't understand , a standalone computer to get you to 9000RPM? I can reach 9000rpm in most of my cars, it doesnt mean they are going to be 200kw.

[bourbon]

look at your gearbox while you do this too...you dont wanna have a strong engine but weak gearbox...youll have all sorts of issues at high RPM...

and batman has crossed over to the darkside and now drives a magna hahahaha

the point was if he wants to get a ZE to rev @ over 7krpm. The stock ECU WILL NOT do this. It can't unless it is flashed. Even then. 8k is achievable, not 9!

Demanius. Your engine is all aluminium alloy & has to be built within tight tolerances to be able to reliably withstand the temps & rigors you propose for your engine. Any heat, fuel leaning & it's cuput! Throw the engine away. Mazda & Toyota racing engineers decided in the mid 80's to keep with the durability of the steel block 4's when building rally/track cars. They needed reliabilty under extreme racing conditions. Ie: simple to exchange a warped alloy head but a warped block? Not really ideal in racing circles.

I just wanna know one thing so I can get a better handle on the build you are contemplating. Why do you want a high revving engine? Is it something you have been looking at or do you want to track race your Astina?

[Demanius]

OK buddies.


i understand all aluminum, there is got to be a way.

i want to track race my astina badly yes, response not forced induction..

basicly like porsche gt3 style of response.


top head and manifold replaced.

not sure, 12.0. to 12.5 forged titanium pistions. the block should be good.


ok, the goal is 8000rpm to 8500rpm, 9k will be too much i feel it yes

bore and stroke kit to 2.7 litres? possibly.


Stand alone computer, is needed pattax to run the custom tuning, and advanced fuel and air mix. for 98 octane only.



perhaps a RX7 5 speed gearbox?? let me know naughty haha

[mkid]

may i point out something (and naughty has as well)
if you want to build a NA tuned screamer you need deep pockets very deep
it just isnt worth it mate unless you building a complete custom show car or a race car
if you want 200kw go turbo its easyer, safer and cheaper
and you can get a lot bigger output
however if you want to spend a lot of time at 9000rpm a rx7 or rx8 is better option
think about what you are trying to do first
a 200kw KL-ZE would be great and impressive
but if was easy and cheap to do a lot more people would do it

i admire your deteremination tho
just dont spend a lot of time and money chasing some numbers that might not be capable

[Demanius]

Thanks Mkid


damn, i know forced induction supercharger would be nicer, more torque

Rx7 is RWD

[bourbon]

ok before everyone jumps up and down...a NA build is alot more expensive but in all honestly i feel its more of an accomplishment...

i ended up getting my BG reving over 8,000rpm with a full NA build still on a STOCK ecu...i dont no how this happened...i just went threw too many gearboxs in the end...if i put a programable ecu in it i would of been extremly happy with the build...although if i didnt sell it, i would of had to of done a massive gearbox build...
