I just rang a place down the coast and they want $220.00 to clean if I take the rail in??????????????

Any one have another idea for a professional clean??

Have a look on the internet. I just had some flow tested and while looking around I found prices vary from $25 to $50 per injector for clening and flow testing. (or you could just buy some new 550s)!

New Deka's are around the $400-$500 mark a set. There was some negative comments about them a while back but mine are running strong on E85.

On car cleaning is not going to work, they need to be placed in an ultrasonic bath. Is there a problem with them? If not, I wouldn't bother. Save up for some new ones mate.

I have a new set of Seimens deka coming this week 650cc

Hugh, it is well worth getting them done. Side feed injectors like you have can be a bit harder to do due to mounting them in the machine apparently. I had a mobile guy do my R33 4 years ago for $150 with them already out of the car.

They should replace the o rings hence the cost of getting them done.

My R33 had 2 out of the 6 injectors 10% down in flow prior to being cleaned. So when people say the factory 370cc injectors can handle "X" power they are assuming all 6 injectors are flowing the same. If 1 or 2 injectors are down 10% that is enough to run to lean on those cylinders. Goodby engine.

Don't buy new bigger injectors unless you have a new ECU to be able to run them.

      R32 GTST - 600KW+ RB28/CD009 Build

      By TurboTapin · Posted

      Car has been running great, I've put about 300km's of break in time on it. First thing that stands out with properly sealing rings is no more noticeable crankcase smell coming out of my catch can. This may seem insignificant, but the constant smell while driving around was infuriating. It's also nice to see my oil level remain stable. Two new issues have developed that I only noticed this weekend though. There's a very noticeable driveline vibration past 100kmh. I only noticed it now as I've been babying it under 100kmh in the backroads. This comes as no surprise as I'm running a one-piece shaft, and I paid zero attention to my driveshaft angle when I put everything back in. I also have a fair bit of voltage drop on hot starts. The starter audibly is forcing. No issues on cold start though. I must not have removed all the paint under my main block ground during assembly. I'll try and take care of both those issues this week once the kids are asleep.  I also received all the parts I was missing for my direct port setup. I will hopefully have pictures of that up soon. I'm hoping to get back on the dyno the week of June 30th as I'll be on vacation. I'm confident I should be able to make north of 500rwkw on pump gas and WMI. I'll go back again later this summer with E98, but I want to confirm my ethanol content sensor is working properly first. I've never seen it read anything but 11%. This makes sense for our 10% ethanol content pump gas here, but I would expect the occasional movement between fill ups.

      The Evolution Of "night Fury"

      By jez NF · Posted

      75% complete. Will now need to get a new axle with 5x114.3 hubs and then figure out how to customize some mudguards for it once the wheels are on.

      The Evolution Of "night Fury"

      By jez NF · Posted

      Trailer prep is underway... Lined up the wheel to get a rough indication of how it would sit Then removed all the bits (as far as possible) and gave the frame a light sand and quick lick of paint   Then added some carpet

      gauge needle removal

      By JC71 · Posted

      okay, so I figured this out, removed needles and reinstalled after swapping the gauge face on my triple gauge for my ER34, all work and look good. I tried to do the same for the main cluster, but the main cluster gauge faces are dished, the replacement gauge face are flat, so due to the dish in the org face ,mounting backing plate (clear) and depth of the needle, the flat gauge face will not work. I notice that R34 gtr gauges are flat, appears to be different clear backing plate that aren't dished. are these available, or what have others done to install flat gauge faces?

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Cheers mate. Seems some people get lucky others don't. It looks like the motor was detonating (to be expected if it was overboosting I suppose) as the pistons had a lot of detonation damage, and the bearings were stuffed. The bores were very scoured too, not sure if that's from the pistons or bits of ceramic turbo. By the by now. Have been trying to avoid the rabbit hole too much on the rebuild, and there's been a few hurdles along the way, but with any luck I'll have the car back soon™. Might even pop up a thread then.
