hi everyone i just joined n4w im from australia and would like to know if there is an easy and cheap way to get more power. i don't know much about engines or exactley what engine i have. i think its a vg30

There are no easy ways to attain cheap power on a Nissan truck or SUV. I

If we are talking about a VG30 with multiple-point fuel injection, known here in the us as VG30E. The only power gains out there are headers, cams, computer. All of which are not cheap.

The only cheap power gains you will get is a complete tune-up. Replace all spark plugs, distributor rotor and cap, fuel filter, air filter and spark plug wires.

will a bigger exauhst system give me any power increase?

Some people say they gain power by installing headers. A bigger exhaust system will not give you any power gains. A higher flowing cat and muffler keeping some resistance is what you want.

I'm running duel straight pipes from the cat back. I did not notice any power gains. In my opinion changing the exhaust on a truck is just for sound. I have not experience any horse power gains from exhaust upgrades.

If somebody would dyno their truck before and after a header install we might know something...

I'm sure you'll have more power...but it might be high up in the revs. Too high to matter.

You're in AU, get a diesel Or a RB...

Welcome to N4W

Largest and Cheapest power gain I have ever seen in my p/u is a full tune up and then run the good gas (premium). The tune up also included fuel injector/carb cleaner.

You could always look at adding the turbo. Not to expensive if you do the work yourself and find a donor vehicle. May cost a little for the donor but keep in mind you will get money back when you get rid of it. Your deal making skill depend on how much you get back.

looing arround @ allot of vehicles, it seems the "bigger" your exhaust gets the higher rpm you have to reach to get your peak power.
I think freer flowing than stock is not a bad idea but I would try to stick w/ smaller diameter tubing too keep a lower torqe band.

Words of wisdom. 2” tubing is fine. They no longer make 1 7/8 found stock on the hardbody.

ok about the turbo. i have found a SRB25 currently running 6psi on a holden vl commodore. will it work without many if any modifications to my engine. and will i still need to get the entire manifold or will some of the patrts from the commodore. all i know about the engine is that it is a 3.0L straight 6. i am waiting for more info on the commodore's engine and intake specs.

the rb25 and rb26 are like gods of Nissan engines. You'll have so much power you'll never know what to do. I don't think you'll have enough roam to put a Nissan in line 6 into a 720 engine bay. The commodore and datuns Z, K240 have long front noses which give plenty of roam for a in line engine. As for the skylines, we don't ever see those here In the us.

I think that about your only option to increase power in a Nissan is to install an auxiliary hamster drive. If you feel like spending big money, you could always put in the "2-cylinder" hamster package.
Of course, if you live in Hill Country you'll have to slip them some amphetamines in their food pellets....

Can you find Ford 302ci V8s in Australia?

What exactly is a SRB25?

SRB25?

skyline motor. Also found in other makes.

word.


There are cheap, easy power mods. Maybe a dollar added( or less) added to a full tank of fuel.

However, to fully evaluate any possible gains in fuel economy/power ( or both) you would need to keep track of your mileage and driving habits without(whatever) additive you decide to play around with.

A solid determination of value can then be determined when you chart your odometer readings/gallons of fuel- without, and with the additive.

Some fuel additives to experiment with:
xylol
acetone
calcium sulfonate additives.

Note: the first two require special care as they are extremely strong solvents . You don't want to get them on your skin.

AND recommended rates are in the range of one to [b]two[b/] ounces per TEN gallons of fuel.

SUpposedly, fuel has a range of molecular weights. SOme of these "weights" are easily burnt( and some aren't). Xylene(xylol) and acetone help to vaporize ALL components of the fuel charge, enabling more thorough mixing w/ air- thereby getting more power out every power stroke.

okay i wasn't sure if it would fit either. i was also considering taking the turbo out and installing it on my vg30e and selling the commodore. would it be possible to run a turbo on low boost (5/6psi) without rebuilding the engine? and if so, how much would it cost to get installed?
