2.3l MZR Engine into the 2?

[Andres3165]

If you want 260+ hp sell the 2 and get a ms3.
It is that simple.

Agree

Yep, I had a MS3 and the 2 will never be at the same level as a MS3 no mater the mods.

I'm looking into make the 1.5l more efficient now, make it breathe better. I thinking of limiting my engine mods to CBE, Dynotronics ECU Flash + what I already have on the car

If someone was to swap in a 2.0 or a 2.3 might as well go big.

Hahahahaha, yes but going big will be for my next car. The 2 is my DD, still I like making the 2 a lil quicker So Derrick, any new parts coming out for the Mazda2? I got my list for winter/spring 2014 all planed out, but if a new comes out I may add it on the list. And my wife's looking to add some suspension mods on to her 2

Yes but the difference in 180hp all motor and 180hp turbo is that the all motor (2.3l swap) is infinitely more reliable with less things to break or maintain than turboing the stock engine. AND you then have to worry about our transmission, 180hp input into our little transmission that can't will cause 2 problems. 1) The gearing SUCKS. It's means for city driving and fuel efficiency almost doubling the horsepower you can just skip 1st gear, and 5th gear is going to feel like driving everywhere in 3rd. 2) The internals will not be able to handle that amount of power for long.

Longhorn? Go Horns!

Very true- an engine closer to OEM configuration is always more reliable. My 2.3 in my 5 put down 145whp with zero mods through the manual transmission, so that comes up to 170hp assuming a 15% driveline loss- no intake, header or exhaust. All OEM.

More power just makes the short gearing more fun?

Most engines on the market can handle a pretty good power increase- but I haven't seen the rods or pistons inside the 2's engine... sad that they won't handle it.

Almost 20k miles now and over 8 months I'm running @ 180-185 bhp with very-very-very aggressive driving .
So far so good. I don't know if it will last longer.

Hello there. Just to inform u i turbocharged my mazda 2 on the original 1.5 engine with some modifications to make the cylinders more durable under pressure , i am running a td04l turbo with 550 cc injectors and i am getting 250plus hp out of it . It is simply outstanding and still lightweight and easy to handle (eekdance)

Welcome to the club

Watch out your internals with the torque and hp that you getting with the turbo.
250hp and how much torque? anything over 25kgm is risky.

 

[Mazda2sp]

I am running just around this number but my compression ratio is considerably low , so the boost level is at 1.2 bar i can say one thing she is a crazy little beast hehehe btw thanks alot for ur info back then it was extremly helpful

 

[AN7]

you are running with lower compression ratio but with stock internals?

Yep, thinking the same thing here, how is this possible? MZR 1,5l has 10:1 compression ratio oem....

250... hoooooooooooooottttttttttttttt haha Great to hear.

With a thicker head gasket you can lower the cr without changing pistons or anything else.

Pretty popular way to do it- the S2000 guys who want to boost cheap throw a 2-3mm head gasket in and boost out to 400-600whp on stock internals. They'll take the compression ratio from 11.1:1 down to 9:1 or so.

Good to know other people who had the courage to turn your small mazdas in turbo cars
Every day we are more (eekdance)

Guys i am going to tell u my secret . I am using mazda3 1.6 pistons which are slightly concave and have shorter connecting rods. They fit perfectly and give a 3mm clearence from the face of the block cylinder to the face of the piston that way i used the oem gasket . And there you have it low compression and a very durable engine 1.2 bar boost and running like a dream

 

[Mazda2sp]

Yeah man it is mazda internals

Yeah those "gaskets" do help, they do look funny. We did an install on a SX4 that we added a turbo kit from a tuner that mods SX4's.

Here where he got the kit from

with a thicker head gasket you leave a weak point in the whole combination which would the gasket itself , now it has to withhandle the pressure and temperature of the combustion chamber , whereas in lower piston the gasket is 0.1mm which is nothing , but the pressure and temperature stays on the walls of cylinders and you have a more durable engine.

True , it was a quick fix till he rebuild the engine with proper internals. The SS4 was a blast to drive and being 4x4/ AWD made it into a lil rally car
