my car (R32 GTR) is down at the moment (damn air regulator, by the way for anyone thinking of using Subaru Upper Engine Cleaner to clean the engine DONT!!)

and it will be down for the weekend so i thought i would use the downtime to polish my intake plenum, coil cover and twin turbo pipe thing (intake plenum and coil cover both painted Black)

so i was just wondering has anyone done this before and have some recommendations or interesting little tid bits/ products that may help or be good

could use info for tutorial on how to do this...

any info would be muchly appreciated

Thanks

I prefer polishing as it is more resistant to scrathes etc, but remember maintenance of anything polished can be a pain also...

I did my SR20 cover one weekend...but with the help of a slab of beer and some bored mates!!!

I will be doing my RB25 soon, as soon as I get another car so I have the time that is!!!

How DID you do that? what product/material did you use?

i wanted chrome but the shop said chrome on ally on hot surfaces will eventually peel and they refused to do it, so we polished in the shed, and using lotsa sand paper, starting by removing the black paint which is tough shit :P flat disk on a grinder is easiest, without making a mess of it, and then hand sanding all the shitty fiddly bits, start on medium paper, to get pits out and then go down to like 800 grit wet and dry with water.

then use hard buffing wheel on bench grinder, then softer wheel and then finally a polishing wheel and use polishing compound on the bench grinder, and then finally finish off with autosol by hand to protect it :D

ive done my alternator, throttle brackets, cooler piping, sump, ignitor box, and a few other bits and peices also, anything ally is polishable :)

Note: i did all the parts including plenum when removed from the engine

good luck

Stagezilla, how long did it take you to just do the valve cover? I figure that'd be the quickest as it's mostly flat surfaces so possible to be done with an orbital sander for the most of it... That said Im thinking of doing that first, will probably make the biggest difference to the engine bay too.. Cheers

      WA PITS: Am I screwed?

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
