hey all, just sharing my freshly powder coated engine covers and plenum,

only problem is that they coated the gasket side of the plenum, so how do i get it off,

cant take it back to the powder coaters coz it was thru a friend of a friend and cost me a carton of carona, and i never got to mention to him not to paint them,,

so let us now what u think of the colour, and best solution to clean up the gasket side

Leave it? Can't see it being that much of a problem?

I'd say just install it with some gasket goo for extra insurance.

If you really wanna, anything abrasive will do the trick, just remember it's ally, don't go sandin' too hard...

Yeah I'd use a buff gun with an aluminium pad or probably could just get away with a normal buff pad.

I used an oil stone on mine after I'd cleaned up the ports to make sure the surface was flat. Do not use anything to harsh and do not just leave it.

FYI, my buff gun was $130 from snap on (its a blue point one) and if your doing alot of surface prep they are a great little tool. I get pads and sanding discs for free from work but I dont think there that expensive anyway.

Otherwise buy a paint scraper and try and scrape it off as best you can then get some sandpaper and rub it down till its nice and smooth. The worst thing you can do is have it uneven or poorly prepped. The hour that being lazy with it will save now will seem like nothing if something happens and you have to replace stuff

Yeh just sand it back LIGHTLY, had the same thing happen a couple of years ago with the BOV flange on the crossover pipe, sanded it back and whacked a new gasket on it and no dramas.

It's very important to keep the surface flat though otherwise you'll be in for a world of hurt with leaks that will never go away.

Whoever coated it should have masked up the gasket surfaces, even if it was mates rate

sand it with the paper on a flat surface, so you dont sand the manifold round. start with heavier. and finish with 1000 odd, you'll be right.

I did this to my powder coated rims around the edge, went as far as 2000 and solvol, but i was polishing it :)

      "Cheap" bolt on turbo on RB25DET NEO

      @Kapr Haha yeah thats the one. I missed that you had a built up engine, I wouldn't want to run it on there either then. It was good in my situation just to replace the original turbo on a stock engine. @MBS206Yep definitely not a replacement for anything name brand

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
