==Overview== RB30E injectors by now are getting to the point where a lot of them are developing leaks. The body of the injector leaks petrol out and onto the inlet port runner and you'll see it staining and in worse cases you can see it forming a drip and pool around the injector. It will be purple if you use 91RON fuel and yellow if you use 95/98RON fuel. This is what it looks like: [[Image:Injectorchange01.jpg|640px|center|link=]] [[Image:Injectorchange02.jpg|640px|center|link=]] [[Image:Injectorchange03.jpg|640px|center|link=]] Okay, so the car in example was just a fairly standard Rb30E Silo, mild exhaust upgrade but other than that no turbo etc. so the injectors I'm using are just off the shelf direct replacement for NA cars. An upgrade with VLT injectors is the same sort of deal. I bought my injectors from Bursons. They're an ACA brand fuel injector. I did some research and couldn't find anything bad about them. I've used reconditioned injectors via ebay before as well, but had problems with them still leaking and having to remove and replace injectors twice after the initial installation. So I highly recommend replacing injectors with new items, however this is expensive. So it depends on how much you enjoy this little job. I recommend you replace all 6 at the same time and not just one or two for the reason that you want the most similar fuel delivery to each cylinder as possible, so unless you've got a flowsheet for the injectors keep them all the same for the best results. From Bursons I got 6 injectors at $60.50 each trade price, so $363 total. RRP is $541.00 for a set of 6. at around $90 each. '''ACA Part number: FI615''' These injectors come complete with new o-rings for the inlet ports and new o-rings for your injector retainers. [[Image:Injectorchange04.jpg|640px|center|link=]] Okay, so now you've got your injectors and you're ready to go. Some of the tools you'll need include: * Phillips head screwdriver size no.1 and 2 * Flat blade screwdriver in a variety of sizes small to large * Pliers - at the least a set of combination, pointy nose also help * Socket set - 3/8 is the best. I used a 10mm & 12mm. An extension is also useful. * Spanner set - 10mm & 12mm, 14mm * Circlip pliers * Pick set * Soldering iron (possibly) * Degreaser/brake clean * Rubber grease * Some rags * White out * Optional: Coolant, drain tray, new fuel filter, new fuel hose, new clamps.
