Best compact 4 Zylinder engine?

[Bling]

4g63 beacuse i have one, and the motor has some serious balls, also the engine management is easy to tune on
which is NOT the case on say a ej20
sr20det is a great motor, stout block which ive seen/helped modify to make 450 rwhp
the old ford escort cosworth motor
or a 3s-gte...i mean top secret runs one in their top speed supra, so you know its go potential

N/A

I would go with one of the honda k20's from an RSX-S or a JDM Integra Type R, They easily make over 200whp with a nice intake and exhaust along with a reflash.

If not I would do a B18C1 out of a 1994-2001 Integra GS-R

F/I

6 Bolt 4G63 from a First gen. DSM

Honda D16z6 with a gt28rs and hondata

Ummm Mazda had a big recall on the Renesis engine as soon as it came out of the factory...They were not makin the power that was claimed (I think thats the basis of a recall


thats because stupid people that run the dynos dont realize the cars computer can sense when there is no airflow and cuts the power....

rotary motors are perfectly reliable, the people that say they arent 99% of the time dont have any experience from them, or working on them. you put good oil in one, and run high octance gas only, and the rotary motor will run forever, people just didnt know how to properly maintain them.

my choices for the best 4 cylinder or small displacement motors would be :

3SGTE : awesome motor, found in toyota celica alltrac and gt fours, mr2 turbos, the naturally aspirated version is the 3sge and found in the jap spec is200 and is 300s, the 3sgte can make over 700+hp prperly built, and there are not majorly weak points, typical to a toyota motor

4AGE : 1.6 liter motor, extremely rev happy and responsive, several varints, the most potent being the 220 hp 11000 rpm group A motor for racing, and the supercharged 140-170hp 4AGZE version, DOHC too

1ZZfe and 2ZZFE, the newest toyota four cylinders, found in the matrix, corolla, and celica, the 2ZZFe makes 180hp and the 1ZZFE makes 140 hp, bot have VVTI and DOHC, 1.8 liters

B16 : Honda, found in a lil bit of everything, the B16A1 makes 160hp, and the B16A2 makes 170hp, both are DOHC and VTEC, one company even sticks these or B18s in old Minis!

B18 : 1.8 Liter motor made by honda, 185 hp in the b18c1 variant (lower compression, better for turbo) and 200+ hp in the B18C5 variant

K20 : newer Honda 2 liter DOHC VTEC motor, 200hp, HAsport makes mount to install this motor in most hondas

SR20DET : Nissan 2 liter made famous by the silvia, 240 hp in the latest variant, can make over 600hp

KA24DE : american 240SX nissan motor, found in most nissan 4 cylinder trucks and older altimas, lots of aftermarket and good stock output, and cheap

4G63 : Mitsubishi motor found in eclipse turbos and talon turbos, 215hp stock and very strong, one variant also used in the EVO making 250+ hp

420A : chrystler/ dodge motor, very mechanically similar to the mitsubishi 2 liter four, this engine is strong, huge aftermarket , with DOHC and SOHC versions, found in neons, avengers, stratuses, etc

H22/H23 : Honda Prelude motors, 200+ hp depending on variants

D16Zc : SOHC VTEC engine found in the 92-95 Civic Si and the 92-95 honda del sol Si, 123 HP 1.6 liter, small, cheap, and large aftermarket

5SFE : Toyota motor, found in older celica GT, and four cylinder camrys and some rav4s, good output, and tough, and cheap =)

13B : Rotay, 1.3 liters, anywhere from 110 hp to 160 hp NA, 210hp to 255 hp turbo.



i prefer toyota motors, but there are alot of really good 4bangers =)

Incorrect. In this case the car was actually not making the hsp rated. They gave everyone involved a few options, including returning the car or getting an extended warrenty.

no you are incorrect. mazda stated the hp rating at 255hp.....SCC determined that the underated HP was due to the computer not picking up airflow and retarding the timing to reduce chances of overheat (primary enemy of a rotary) this was also varified by several other independant dynos and experts. mazda gave the rebates and what not cause most people would bitch and whine regardless, like the current situation with hyundias or kias being overated by 4hp and its gonna cost them millions.
the rx-8 situation was caused be people not familiar with the cars electronics, if you put the car on a dyno, and put say a 75mph wind in front of it, i would bet it makes the right HP, or put it on an engine dyno with a workaround for the airflow

i know this cause i work on rotaries often, including 2 RX-8s....

Funny, thats not what mazda and my dealer says. I guess mazda just recalled the car cause of someone elses screw up.. yeah sure thats believable. Car companies are out to make money.. People bitching is better then people sueing.

Furthermore, your talking about a 75 mph wind... so that means your not getting the correct hsp in 1st second or 3rd gears apparently if I understand you correctly.. So the only time someone is going to get a proper run without retarded timing is already going 75 and hitting the gas.. Thats kinda useless considering very few places do you accelerate hard from 75 mph.

You have even said you assume it will make the right hp. Well Im telling you it doesnt.

Wasnt this exactly what I did?

[PaulGT2164]

Funny, thats not what mazda and my dealer says. I guess mazda just recalled the car cause of someone elses screw up.. yeah sure thats believable. Car companies are out to make money..

of course thats not what mazda says, they would just eat it than dispute it....lots of car companies do that, why risk court battles, and all the publicity, just add small rebates and what not...they are still selling like hot cakes

i know what i read, and the sources are trustworthy, and it makes perfect sense, but you can believe what you want, you know...its not like i work on them often or anything (about twice a week FYI) i know the car very very well, and i will attest to it making the 250+ hp originally stated....if i had a engine dyno and the resources i would prove it, but i dont, but luckily others have proved it already

"Furthermore, your talking about a 75 mph wind... so that means your not getting the correct hsp in 1st second or 3rd gears apparently if I understand you correctly.. So the only time someone is going to get a proper run without retarded timing is already going 75 and hitting the gas..

im just saying here that they need to simulate real world conditions. dynos are not really that accurate.



i dont particually care what you think, ive stated what i Know, so lets not do our usual bickering, ill stick to what i know, you stick to what you know

[itsthepham]

thats all crap .. the KING of four cylinder engines would be the Porsche 968 motor .. 3.0 liter Big Bore four ... Stock it puts out 240 H/p to the Crank .. if you need a motor .. that should be it .. i have a 944 and it pulls hard for a 8V .. the 968 engines are 16V and come with VarioCam - done deal
