How To Get More Power From A Naturally Aspirated (na) Engine

[ARTZ]

for a few hundred more they could put a turbo on while their at it and make it a real car

[Captain Natro]

Don't need a turbo to have a real car

[MBS206]

But you do have to be able to run quicker than a 13.5 if non turbo

well i guess just sticking another 3lts of motor in there could suffice...but thats a 10k excercise....not everybody is a drug dealer Nick

Interested to know how you NA boys go with header design.

Ebay header design studios

but don't worry...they don't sound like RB30s

[Captain Natro]

I stuck with the stock headers, they're already elongated and split (flow decently), seems like a waste of money for the 4rwkw you'll gain.

[XGTRX]

So was that on a stock head. Because I thought a smaller NA engines responds better to good header design.

Well in a way they respond ok (when you extrapolate figures out based on Cc/kw gain) but it's all just a number on a page, <10 rwkw gain won't be noticeable. You might think you feel something but it's a placebo effect.

Have seen (and can give proof if required) many non turbo RBs go 95-110rwkw with an exhaust and intake (fluffy dice and a subwoofer etc).

They just don't turn the numbers needed to move the "heavy" skyline chassis. In my mind $600 for <10rwkw (not to mention the low end loss of torque or the time and money spent making it fit) is just not worth it.

[XGTRX]

Fair enough. Didn't consider the weight issue. Suppose I was thinking of the much lighter cars responding better to the mod. But yeah power to weight ratio wouldn't change much as you said. Thanks

Hello, I have a 1998 R34 coupe and im having some weird problems.

The other week i got in to drive it and when i unlocked it problems started,

1. The tacho and speedo dont work,
2. The bell chime for door didnt chime,
3. The interior light stays on,
4. The passenger door wont lock with the button on the remote or drivers side panel.

It still starts and drives fine,
I disconnected the battery and reset the ECU which worked, but then it happened again and again now that trick only works sometimes.

Any ideas thanks

That doesn't belong in this thread

You have a wiring or earth problem somewhere. Look around anything you have touched recently

quick question, are the stock gtt and gt panel filters the same!? thanks

[niZmO_Man]

Ye they should all be same (across RB's and some Holden).

[Whoa Black Boaty]

I'm going to be on my p's for a while. I have a 95 r33 gts rb25de and my cars completely stock besides k&n air filter.
What mods am I aloud to do on my p's in Nsw?

[The Bogan]

Best mod for a n/a Skyline is to save money and buy something good later when your not limited by your licence.

The car is to heavy, you will never achieve a good power to weight ratio.

Put it this way, you can spend 10k to get 50hp on a n/a, while winding another 5 psi will net the same but cost a boost controller and tune on a boosted motor.

Best mod would be tyres, handling.

Unless your rich and can afford to piss money away.

[Whoa Black Boaty]

I might go wheels, tyres. better sounding exhaust and just save for a r34 gtr or something. Thanks mate
