Honestly, save your money for a proper upgrade to a turbo once your license allows.

The cost versus power gain is pretty poor, I doubt there would be 5RWKWs gain, maybe a little bit more torque.

Spend your money making it handle better, enjoy winding roads, become a better driver, then upgrade to RB25det for more power down the track.

Years of wasting money on shit that cost plenty and made little to no difference has led me to this. Plenty of smarter people gave me the same advice; but I had to learn the hard way.

Cheers, Dale.

If you are going to turbo it later you will have to redo your exhaust so save your money. As above you can make your car go faster by improving suspension, tyres and brakes!!

Dude, NEVER underestimate the benefits of pulse scavenging.

All the NA motors I have ever owned have copped a set of quality extractors as soon as I could afford it. The earler you get them on, the sooner they start paying for themselves, as you WILL see a definate improvement in fuel economy as well as a slight bump in power. Make sure you get a new cat fitted at the same time, and ask your exhaust place if they can flange the back end of your extractors and get the cat bolted straight to them, rather than have a piece of pipe between them (because it will help if you ever get caught out on an exhaust mod and have to do the gas test - the closer the cat is to the extractors, the quicker it heats up and provides positive test results) Its not always possible due to space constraints, but if it can be done it is really worth the little extra effort.

I am a pretty big fan of tri-Y's, and have used them to great effect, although mainly on larger, oversquare 6 cylinder engines such as the ford 4 litre, so get some advice from people more informed than I, on that score. Genie have always been exceptional, if a brand suggestion is needed too.

You can ALWAYS sell second hand extractors, so I dont think that any future "might +T it later" arguments should put you off.

Oh, and try and get the extractors either ceramic coated or at least thermo wrapped - makes a huge difference to thir performance, as well as under bonnet temps
