yeah i need to get my injectors cleaned 4 my nissan skyline r33 its a 95 model and its non turbo, manual. I was going to get them done but the guys that do it told me over the fone that they would not do them cause they will leak or could leak and then they have to do it again and that ...cause of warranty and that ....so its not worth there time i think....so they said id have to replace them...others told me they can do thme no problems.. so what do peopel know from experience doing this my car sort of jerks a bit sometiems when you take of and that. so i think its the injectors...i live in dandenong north, melbourne.....does anybody have any advice or know anybody good i can take it too in melbourne....or maybe its another problem who knows.

regards brian

Im getting them cleaned cause it says on the message..on top that the car jerks a bit when i take of or at low revs in the first few gears...i wnated to do a carbon clean in answer to another message but i cant find anybody that does it here. i contacted one that did it a company but they said they got rid of that cause...it didnt really work. i wnated to do it on the car so i would not have to take everything apart... maybe someon that does this job in melb..the carbon clean even if it doenst really work the best...better than nothing...yeah

Why they made the statement of them leaking is that as injectors get old and wear the carbon seals the wear points, so after cleaning them hence removing the gum that seals them they can then leak. When mine were done there was up to a 10mil flow difference in some, on the flow bench. One leaked so had to be replaced. This was on my GTS-X that has done 161,000 ks

Ok cool yeah. mine have getting worse as well. so i better get it cleaned. Hopefully will inccrease my fuel economy and more power. then again my non turbo r33 2.5, 5 sp manual doesnt seem to waste much petrol anyways so thats good i guess. hopefully now it will waiste even less. and hopefuully none of the injectors will leak after cleaning

Yeah thnaks for the responses that i got. I will ge thme cleaned see how i go. Also a mechanic i go to now in dandenong who imports these cars told me that, it could be the spark plugs cause i cleaned them witha wire brush and that, he said teh lead deposits can make it missfire, but i dont think, so cause the first time i cleaned them they were ok and the problme started long time after that was done.

Yeha i got the injectors carbon cleaned the guy ran the car with these liquids for like 2 hours...the car went for ages and this black stuff came out ..all the carbon deposits...smelled like someone had been using an angle grinder or something. but now the car does not jerk anymore. and i saved all the work of taking the injectors out and that. plus i have been told the injectors on skylines usually leak afterwards..so they are usually just replaced and that, instead of cleaned. its not worth there time cause thne they have to be taken out again. I also bought new spark plugs, so hopefully that will make it even better than it is now.....also i wnated to ask what is teh spacing for an R33 rb25 sparkplug is.

im not sure. does anybody know.

I have never heard of the injectors leaking as a common problem with the Skylines.

The Oz R31 - yes, they have the rb30 injectors though. They may have had them confused.

The RB30 injectors are well known to leak after a clean but the other RB engines do not have this as a problem as such - not saying it can't happen but it is rare.

How much did the carbon clean cost you?

Hey maybe you are right about thme leaking maybe they got it wrong or were just crapping me... and that . yeah to clean each one was like 35 each which is like 210 plus i had to take them out myself. if they do its extra.

and the carbon clean was only 130 for the job which they do on the car. I got it done in clayton thast in the south eastern of melbourne.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p

      Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.

      Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from

      Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
