Engine Swaps Besides the Conventional

I read some of this and all I could think of was what about the 800hp twin turbo KL pic that I seen floating around. That is a perfect example of the power you can get from the KL motor.

You are coming at this thing from a totally odd angle.

You don't really want a 300bhp Mx3.

You want a 300bhp sportscar.

The Mx3 is great little car, and being able to bolt a 200bhp motor into it takes it to a whole new level, and lets a 10 year old, 4000 dollar car play on the same level as the hottest of new hatches.

Beyond that, you really want a sports car. Have a look at some of the below suggestions. All of them are quicker, handle better and have better tuning options.

Porsche 928 - 350 bhp stock V8

Rx7 Efini

Celica GT4

Evo

TVR

Mr2 turbo

And you could take any of the above to 500 brake for the same price you would getting the KLZE to 350 brake.

It all depends on what you want. I know at the Ottawa cruise I was easilly hanging with the Rx-7's, turbo FD's and all.

The Celica GT4, the Mitsu Evo and the TV2's are not available in Canada.

But I'm in Canada and I've driven a GT4... It was an 88 model, but it was still kickass.

Have a close read, thats a 2.7KLZE N/A with basicly cam's and custom
intake, and extractors with a very mild port pulling 326hp@flywheel
and a very flat torque curve thats not to vilolent on the gearbox.

The mx3 is a very heavy car, i know ive gutted one out, the amount of
fat you can remove is not funny! hp sell's cars torque win's races

i read this thread and had to reread it 10 times.
kiwi, what's the secret with the motor? from my reading, making 200-210 hp at the wheels (approx. 230 at the crank) is like a dream come true for a n/a motor.[/b]

yah the mx-3 is a girls car as thats what it was marketed audience was females.... but hey people consider the miata a girls car also and they are fun to drive i'm sure.... if u properly modify the appearance of the mx-3 usually with body kits then u get a much more aggressive looking car... i feel its mainly to do with the headlights.... curves are just so damn sexy... this is what it should look like

thats not a girl car

Not really any secret, the stock intake system is quite restrictive
and the stock ecu is not aggresive enough. and a few other changes

It ildes like a sack of s---, in fact most peaple think its a bridgeport rotary
till i get the b---- up on the cam's, the current mainafold system only gives
me Wide open throttle at 3000rpm hence it drops hp at 3500 then gets up
and goes from 4000 onwards.

Mark two system with be a single throttle instead of the twins in running
at the moment,

Motor consits of

Eagal 5.4 I beam rods
Toyota 2VZ-FE pistins
Underdrive crank and water pump pulleys
custom adjustable cambelt and camgears
Custom cams 230 degrees duration running at 90 centers
( you could go to 245, and gain more top end hp but the bottom
drops out )
Stock Valves,
Non stock valve springs and retainers
( SOILD LIFTERS INTAKE AND EXHAUST )
Custom intake system running bocsh 330cc injectors
Custom exhaust system , running twins right to the rear
Bit of mild porting
Link ECU, custom HEI system, 10mm leads
12lbs flywheel

and a host of other stuff that ive forgotten to list.

The motor will pull to 10,000 rpm mated to a autobox with a
4500 stall converter in her would be the ideal drag racing setup
as i have fried a standard box blew third gear to peacies ...

The cost really is in the heads as it cost me 1600, to build the bottom
end including parts and labour.

pretty impressive. it would be nice to see the results on the track!

by the way kiwi, what is the compression ratio on this setup?

Teqnyck · Post by **Teqnyck** » August 1st, 2006, 11:04 pm

The comp ratio is 10.5:1, and it's actually Nissan pistons. Out of a 300zx turbo. I agree that the Mx3 is a girly car, but thats what makes it such an awesome car to mod! It's such a sleeper! It handles very well with the right suspension, and while not a LeMans car, by any means, it gets the job done. Someone mentioned that the miata was a girly car. I had a miata for a short period of time, raced with it, and it was nothing short of brilliant. If you know how to race, you'll find the limitations of the miata very high, even with stock power. Sorry to ressurect such an old thread, just wanted to put in my .02!

those headlights look kickass
is that the MX headlight lense, or the one that came w/ the projectors, or a custom one?

(sorry for the quick hijack)

but i agree that if you're looking for any real amount of power that you're willing to throw money at....RWD is the way to go.
if money is not an object, then just start w/ a tube chassis and go w/ a RWD engine (any pretty much) and then put the MX-3 body overtop.
saw it done in spring w/ a 03 sunfire...rwd V8 running 9s

To Mr Teqnyck

first off the question was directed to me, and what i have posted for
my engine is what i am using, how do i know is i built it and brought
all the parts and machined the piston's to suit the Ch and lenght.

the nissan piston ( VG30DE ) and turbos
=CH=32(+1.3)(-2.61) L=59.5MM.

Hmm not looking to good since a KLZE piston stock has a Ch of 30
even though the 5.4 rod takes away 0.025 still to much pop up.

the Toyota piston =ch32(-2.0) , simply machine 2mm off the top
turning the piston into a 30ch and a flat top with the valve cutouts
in the right place. and turn it down to stock lenght of 63mm

Ive had the block decked 0.025 to allow the new rods to give me a
comp ratio of 10:1 without even touching the heads.

There has been a number of threads on the 2.7 setup and i can say
they are all junk! even my engine machist was laughing

Teqnyck · Post by **Teqnyck** » August 2nd, 2006, 12:08 pm

Didn't mean to offend, kiwi. I hadn't realized that you had build a 2.7 liter KL! There is another guy on PT that used 300zx pistons, I thought that was the engine you guys were talking about.

Sorry!
