Rb25De N/a Chip Options

[SHANE666]

piggyback it for N/A.

[PM-R33]

That's all I want 0 to 100 in 7seconds.

Unfortunately that will be hard to achieve.

A stock R33 GTST does around 6-7 seconds depending on where you read the information from and given how old the cars are now the results can vary quite a bit from one stock car to the next.

Nah think I'll just wait. Lol

[mad082]

I wont say anything

good, LOL

[Mooney]

sorry to hack but since we are on this touchy subject, does any one possibly know where i could get a chip for a RB25de but non vvt version (ones that come in r32's)?

cause all i can find are r33 ones and they apparently dont work

[mad082]

do you mean a chip or an aftermarket ecu/remap type of thing. any "chip" that you simply plug in or have soldered in that already has the tune on it is the absolute worst thing you could even think about wasting money on.

Mad082 I have found a cheaper way to INCREASE POWER high octane fuel additive!!! Lol I seriously think this suff works there around 20bucks a bottle though I couldn't imagine how hard your car would go if you use a full bottle of the suff with a 1/4 of a tank left

there you go BOYS!! go kill some holdens and fords note. That I havent tried this though someone should!!! and let me know how it goes.... You can buy the stuff at repco.

[Socrates]

Will do nothing for you

[bikerboy14]

How would u know have u tried it.

[Socrates]

I don't own a modern skyline so can't tell you

from what I've read there's potential of fouling plugs by using fuel additives like that.

the money is best spent on putting 98 RON premium fuel in cause additives aren't the best way to up your fuel's octane rating.

[bikerboy14]

Well I notice alittle more power. After octane booster so that's my opinion. I don't think it would damage the engine as it is only increasing the octane in your fuel. As long as you don't go crazy with the stuff. < I don't care if you do<< you should be right.. Try it your self I bet you'll see an improvement in what ever you drive. it cleans Ur fuel injectors to..

If you are living in Sydney maybe I can remap NA R33 ecu.

But you can not get 20kw gain.

I think around 10kw.

Do you feel a difference when you run 98 octane fuel compared to running 95 octane fuel?

[mad082]

higher rating octane fuel will give ZERO power increases in a correctly operating engine if the engine was designed for the lower octane fuel. if however you start increasing the timing then you can run more advanced timing with the higher octane fuel so you can actually see a small increase in power (to put this into perspective, a natro SR20 will gain 3hp from about 2 or 3 degrees more timing. personally tested on back to back runs).

if your car was designed to run on premium and you run it on unleaded then you will see a bigger difference when you go back to premium after running unleaded.

i think a lot of people don't realise what the octane rating actually means. it simply means that the higher the number, the harder it is to ignite the fuel. octane rating has pretty much nothing to do with the actual explosive energy of the fuel. in most cases higher octane fuels have a lower energy output.

I just want enough power in case a xr6 or a sv6 comes next to me on a race track;). That's all I want 0 to 100 in 7seconds.

If it was really for a racetrack you would do a bazillion other things to the car before even looking at power

If it's for traffic light heroism...a proper LSD...big tyres...will do more for your car than any power mods. Keep in mind that your launches and shifts will have to be flawless to keep up with automatic variants of the cars you've mentioned, as I even had to try a little bit when my GTS-T was standard. But really, don't bother with it...it's not worth spending the money on a car that is so readily available in a much faster model (turbo) when you get off your P's. If you want to beat those cars in a race, go get a motorbike.

Toshi thanks for the offer though I live 4 hours away from Sydney lol

Mad082 what do you think of my idea of forced cold air induction. What I mean is for example a 4inch PVC pipe collecting Air from the front of the car then being sealed onto a pod filter. So at 80kms it would almost act as a turbo would it work in a non turbo and would the engine be able to deal with all that extra airflow

Exactly. Hence what I was getting at with my question to him.

Lol doesn't quite work like that unfortunately.

Yes it would be a good thing. You would be supplying colder (denser) cleaner air to the engine. Maybe gain a couple of horsepower at certain RPM points. Would it be anything you would notice? Nope.

Seriously, you have to understand, the RB25DE is not an engine that you can get power out of without spending a lot of money. They are a small displacement N/A engine in a heavy car. With all the bolt on mods you could think of you would be lucky to gain 30-40hp (which is probably what the engine has lost with it's age). Have a look at the dyno thread in the N/A section. All the power figures are poor. Only a select few who have wanted to spend larger amounts of money have gone beyond the norm, which is still less than what a GTST would make.

Save your money, sell the car once you get off your P's and buy something else.

[Birds]

I bet you most of these people who want the fastest P plate legal car on the road, and start these threads asking for ways to increase power, have not honed in their drag racing skills (which is evidently a free modification) with the current vehicle setup. So much more to be had from doing that.

the gains would be minimal (under 5hp). i doubt you'd see even 1psi of pressure.

[bikerboy14]

I think I should test it out one day only thing I have to worry about is the engine not knowing what to do with it...
