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

Don't need a turbo to have a real car ;)

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

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.

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

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.

    • People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.
    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
    • Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.
    • Yes that sounds right. Cars currently in the shop for the engine work. Will need to remeasure .. but yes I think I must be targeting 45cm from fender. 
    • You have your numbers back to front. 350mm from wheel centre to guard lip would be scrapinly low and the suspension arms would be at spastic angles and it would have the road manners of a meth affected giraffe. You can down to ~450mm (from larger stock starting values about 50ish mm higher than that) before you start to create to many problems.
