Making A Skyline Run Richer?

[LO_R33]

Hey guys,

I did a search but couldnt find much, and was wondering is there any possible way without spending to much money making a car run richer? is there a controller i can buy so i can make it run richer with the flick of a switch? if so, where can i get these from, and how much are they usually if they even exist.

Cheers

Get it re-tuned

I didnt exactually want to have to get a new ECU

why do you want to make it run richer?

it's already quite rich as it is

but the apexi safc or the jaycar dfa is probably another way to make it run richer

or otherwise something that can amplify your afm signal?

I'm intrigued too, why do you want to make it run richer?

I guess an easy and free way is to junk the O2 sensor. The engine will sense this and run richer by default to protect itself. This will ruin your fuel economy though, as if R33's arent thirsty enough already.

I've never tried this so correct me if I'm wrong anyone

The only reason I can think of is to make the exhaust pop and flame.

punch a hole into one of your intake pipes...

that will make you run richer.. you might even go thought a tank of petrol in 10mins if the hole is big enough..

im assuming u want to run nitrous?

Agree... just ditch the O2 sensor. My O2 sensor is stuffed and I am running super rich, getting 220-300Ks per tank. Occasionally hear popping sound from exhaust from unburnt fuel being ignited and soot all over the rear bar.

I found a correlation between car running rich and the owner running poor... from increasing petrol price

Spot on mate! I've found a kit by NOS and it only requires you to make your car run a little richer. Thats why i was curious to how to do it, it looks like an apexi safc is the best way to go, however my car does run fairly rich as it is (already makes nice flames).

I'd say the skyline 'might' run rich enough to take the nitrous kit as it is, but i think it might be best to have a controller anyway.

Cheers for the help those who actually suggested some good ideas.

sounds like a good idea, but it would be better to get it tuned for the nitrous on a dyno. Itll be a hell of a lot safer.

I agree 350%!!!!

I wouldn't run Nitrous without an ECU that can be tuned to run it properly. You'll grenade the engine in no time.

contact 2rismo on the forum, he runs Nitrous in his R33 GTS-t on the drag strip

[PHATR32]

from reading the diy intrusctions from NOS, they reccoemnd retarding the timing a few degees to avoid detonation. so, youll need a circuit that richen your mixture while retarding your timing?

dunno, never used nitrous. youd be better off talking to a pro.
