A Few Air Compressor And Spray Gun Questions...

Hi Everyone!

So I am thinking of getting an air compressor to (mainly) paint the damaged door of my R33, touch up my spoiler and front bar, and a few other things around the car. This will be the main reason for purchasing it, but I am also thinking of using it around the house, just to do some light duties, such as spraying the fence, inflating tyres etc.

I didn't want to get one that was too expensive, so I have been looking at the ones available through Supercheap, Malz and Bunnings.

They seem to all be around the same size and same price - this is what I am considering at the moment - which one would be the best for me?

Supercheap

$199

- Black Ridge 2.5HP Hi Flow Compressor

- 40L tank

- 115 PSI max operating pressure

- 200L/min free air delivery

or

$119

- 40L tank

-115 PSI max operating pressure

- 120L/min free air delivery

Malz

$149

- SRT Air 2.5HP Direct Drive Compressor

- 40L tank

- 125 PSI max operating pressure

- 131L/min free air delivery

Bunnings

$199

Project Air 2.5HP Direct Drive Compressor

- 2 x 10L tanks

- No other specs

or

$137

Project Air 2.5HP Direct Drive Compressor

- 40L tank

- No other specs

Also, with regards to spray guns, do I go for a:

- low pressure spray gun?

- high pressure spray gun?

- gravity fed spray gun?

Thanks for your help and feedback,

Pete

the top ones the only one that will really flow enough air for painting..problem is at 200lt per minute and a 40lt tank it is empty in 12 seconds :yes: ..

I have one and its a noisey POS but it does do the job..I wouldnt want to paint a whole car with it but for short bursts for a few minutes its fine

either kind of paint gun will work as long as its high pressure..

I usually just paint with cans though its much easier and you can get a good finish..

I'd go for the gravity gun for what you're doing, unfortunately I'm not familiar with how well the cheaper brands fair as I always used Graco units, a pressure pot unit is really only used for thicker products (industrial epoxy coatings etc etc) and wouldn't give as good a finish as the gravity gun and it's really easy to overbuild the coating if you've never used one.

you want a compressor with some warranty on it. All the cheap ones break sooner rather than later. Go price up a decent one and look at what the differences are. You also need water traps, connections, hose etc, so it all adds up.

The gun should be gravity fed, and a HVLP (high volume, low pressure) to spray the car with. Best bet is to also have a look around at the various types as buying the cheapest can also mean headaches. Different sized needles are needed for different types of media, like undercoat, primer and paint. Speak to the paint supplier as they can offer the best advice for the paint you want to eventually use.

I have this compressor. It is good to use but like someone said it does empty the tank quickly, which can be annoying. But for short busrts of work it is good.

However trying to cut through something strong can pose an issue. Use an electric angle grinder for this.

Thanks for all the replies!

I have taken everything into account and as recommended will look around at what other compressors are avaiable, to see if increasing the price slightly makes a huge difference. I'll also speak to a paint shop to see what they recommend regarding the type of gun and the size of needle required.

Will post up what I find out.

Thanks again - great advice, and I'm glad I didn't just go straight in and buy something that wouldn't do the job.

Cheers,

Peter

      EFR7670 exhaust selection RB26

      By LegendGTR · Posted

      I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!

      OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
