hi i bought an engine and put it in from SSS automotive and i didnt know u should put ur old injectors in the new engine or get the new 1's cleaned since they would have stuff dried out in them. nehow i was told the old petrol has dried up and now since they have had new fuel in them the old stuff went sticky and blocked them

neways i got a dyno and they told me my injectors are playing up and need cleaning...

so i was thinking im taking the head of my car tomorrow and i wanted to know is there some way i can clean my injectors when i take them out at home,

cause it would save alot of money??

are you sure of this? i mean engines and injectors run for many 100,000kms without any cleaning or changing etc and they work fine

oh i forgot to say when i had it dyno'd they took out my fuel filter, it must have been that old the filter broke off its casing and all the stuff in it must have went through into the injectors

Yeah cleaning injectors is no problem if you have your own ultrasonic cleaner, maybe a jeweler could do it cheap their their ultrasonic cleaner, done by pros who does fuel injectors your looking at about 20-40 per injector cleaned.

Show me a 'pro' that uses an immersion ultrasonic cleaner to 'clean' fuel injectors and I'll show you a 'pro' to run a mile from. Using that type of cleaner WILL result in damage to the injector pintle valve (it's a type of wear damage and the technical term is false brinelling)

A 'pro' that knows what he is doing will use a dedicated injector cleaning bench in which a special cleaning fluid is passed through the injector as it is cycled using a dedicated controller (ie very similar to the job the engine ECU does). At no time is the injector body immersed in the fluid.

      Exhaust silencers/varex exhausts

      By PotatoCake 路 Posted

      Yeh... literally every time i jump on a forum, see an instagram post or see an engine bay at a car show, i get an idea and add it to my 'to do' list. So what started off as, hey can u just make a couple of intake hard pipes because my dumbass bought the wrong apexi kit, blew out into a 2 week job including braided brake lines & custom bash kit for the front lip haha.  Getting Luke from A4E engineering to make a full custom exhaust with a controllable aes dump valve so i can actually switch between quiet and loud, because right now its just loud all day every day. Then after that go and get the tune redone flex e85 & 98 as i get bugger all milage from e85, makes going for longer drivers difficult

      Car looks clean as. You ended up getting quite a bit done 馃槀  So what's the plan for the exhaust?

      Rb25det vs Rb25de rods and crank are same?

      By GTSBoy 路 Posted

      The only Neo rods that were any different to any other RB25 rods were the DET ones, and they were the same as RB26. Here is a Neo DET rod. O5U part number visible. Here is a post in a thread here on SAU with evidence from someone who has done this before. There are photos in the thread of normal RB25 rods.

      Magnetic Drain Plug Snapped in Half

      By joshuaho96 路 Posted

      Sure, but why assume that will be the case forever? And why assume you'll be able to do an oil change to swap back to a stock drain bolt before that happens? And does it even matter when I change the oil at fairly short intervals? Life can be funny sometimes and unexpected things can happen. Like breaking a collarbone so you can't do any work on your car for a few months but the oil change is due so you have to take it to somewhere and hope they don't do something stupid like stacking the new drain plug washer on top of the old one.

      Do u know how to identify the rods are rb25 or neo ones? Can u look into the pics and tell me is they de or de neo ones. Its confusing becoz my motor has de neo head but block is 25de 75t, so really confusing me about rods, crank.
