my 240sx ford 302 engine changes (lots of pics)

[maik21]

i found why my car seems to be a little underpower.













i will add more fuel throught 2000 to 6500 rpm. i go back to track maybe on 2011 and test it.

this video its the complement of the past video.

[maik21]

finally i got my wideband. its a kit so i need to assembly.





this kit dont come with lcd or 7 seg display, so i need to see O2 values on laptop or datalog.

[maik21]

wideband done 100% .

i test yesterday at night and car is running to rich at wot. afr was 10.9 - 11.2 from 4000-6200 rpm.

i set afr to 15.0 at cruise and under 3000rpms and under 50% of load.

You must know quite a bit about electronics, not sure I would tear them apart like that, too afraid too make a mistake and destroy an investment. I'm not usually a downer, but you could have saved a lot of time by saving and doing it all at once, but you obviously have lots of time to tear down and rebuild multiple times so all and all its not that bad. Keep up the good work. DIY rules.

finally it runs better.

i went to the track and it did 12.4 on 1/4 mile. car maybe can run a little more faster but they close drag track early.

pictures ftw.

in this video i was driving and then my brother drive.

It's been a while since I remember you throwing the swap idea around. It's good to see it come this far. Proud of you paisano...

[maik21]

thank you!!

[maik21]

well, i have some things for my 240.

its a t4 rotary(or something like this) . fd3s..


ic + extras

Al tube.


and this is what i have right now.






and this is the co-pilot manifold.


yeah, it looks ugly and i sucks with flux core welder !!

i only want some extra power in the 3rd and 4th gear. f303 cam its used with forced induction.

wastegate is set for 4psi and maybe i will run 7psi. i have a new map sensor(2 bar) for turbo setup.

[maik21]

[maik21]

a friend of mine sells me one custom made in $7 usd. i will wait till friday. i need this car running again.

like what do u have to move the firewall to fit and what transmission are u running cause if im not mistaken the t5 has a cable clutch instead of a hydraulic

[maik21]

my car was atx so i install a 200sx b14 pedal clutch. it uses a cable. transmission is a t5 from a 5.0 v8 ford. it uses cable too

[maik21]

i need to cut spark plug wires and clean engine bay.

[maik21]

wideband seems to be reading wrong. car went to lean at wot but car stills pull hard and no knocks.

it reads good 11afr and then it goes to 19afr. i test car at least 8 times.

this are old videos...

in this videos, cars lost power at lean condition.

so never put a turbo on a holley tbi. its hard and maybe tbi isnt really well for 350hps or more. inside line fuel into tbi its very small so it can lean your afr. i put a fuel gauge but it didnt show this problem. i didnt take pictures of inside tbi fuel lines.


i will put pictures of a solution i found on net.

so here are the new videos. car seems to run very fine. its strong but dont kick hard as when it was NA.

car is on 4psi of boost. ignition timming start at 26° and a max timming of 34° at wot past 4000 rpm.


friend's car is a tsuru gsr 2000(sentra b13 se-r usa.) it runs los 15s NA without nitrous. car has a nitrous 125 shot.

blue headlight is 240sx . car was lauching in 2nd gear with 2 step at 3500rpms. this were taken outside car.

[maik21]

tbi mod for better fuel feeding.

fuel inlet as fuel inlet. fuel outlet as fuel inlet.

[maik21]

Finally i put 2 bar map sensor. i will switch from 4 psi to 8psi soon. i did a little map tuning and it is rich but safe and can move without problems.

this is my homemade wideband gauge. 6 samples per second for easy visual reading. it can work 20 or more samples per second but turns hard to see. i put some leds under display so you can floor gas and if you see green light all its fine. green light is for afr from 10.0 to 11.9
[youtube]http://www.youtube.com/watch?v=EZBLpw9S4Jw[/youtube]

i put some better fenders and i will switch for better hood too.
side skirts are there too.

engine temp rise from 175 to 185 and sometimes it went to 200 on highway. so i cut bumber.









there is no time for a good paint job. i will paint with a cheap paint and make it one color. 15usd for 4 liters of paint and 4 liters of thinner. it will be white again.

[WDRacing]

Will look good with some new white paint!

[maik21]

yea. white color will be great. problem is i dont have a garage to do the bodywork and then paint. i have a lot of flatblack paint but temperature is to high outside and black isnt a good color for this time.
