The paint or not to paint in relation to performance gains/losses has been done to death and speaking from experience and having 2 temperature probes measuring ambient & intake temps, it made bugger all difference before or after painting mine. Too many people spend too much time arguing over the intricacies of a mod that may gain or lose you a couple of hp. Pffft - like you'll notice it!

As for longevity, small bits of paint do come off a little every now and then but all you have to do is get a spray can and touch it up - without getting it on your bumper :(

Attached are a couple of pics of mine when I did it a few months ago.

Excuse me for my ignorance - Would painting an intercooler create any restrictions on flow, or would it have any effect on the radiator??

Just to me, it would seem that by spraying a coat of something that bonds to the surface of something that takes airflow, would it not clog or block it up similar to dust or sand or gunk???

My car has a black intercooler anyway, so makes no difference to me (came with it when i got it, and i assumed r32 GTR's came with a black intercooler as stock???)

Would it not be a better practise to have the front mount anodised in a selected colour? What cost would be involved.

I had a neighbour with a WRX that had his fm intercooler anodised in gold to match his wheels and colour scheme or the STI

Simply mounting an intercooler in front of the radiator would have MUCH more of a flow restriction on your radiator than any coating on it, but that's what the thermofan on your radiator is for - to kick in when the coolant is too hot (even if it's caused by lack of airflow to it).

As for clogging up the fins in the intercooler, you have to to driving through some VEEEEERY hefty bug swarms to do that. The paint is not thick enough to block the airflow through the intercooler.

And yes - all the GTRs have a black intercooler as stock.

      New Stegea Owner

      By thomasLait · Posted

      Hey everyone, I recently bought myself a 2001 Nissan Stegea M35, and I've had a few issues that I had to fix, my car would start intermittently and I had a bad rocker cover leak, after a couple days of looking I finally found a part number that interchanges with the OEM starter as the OEM starters at $1300 and I can't afford that, this starter was only $270 and I replaced the start and still had the same issues, I posted a video asking for help online and it went very well, some guy said it was probably a bad ignition switch so I took my dash apart and turns out my ignition switch was half screwed in and was loose, once it was tightened it fired right up, I found a local place called "Boost factory" and they sold me a part of OEM Nissan rocker covers, they were $600 which was a shocker but I couldn't find them anywhere else, so I installed them and fixed my oil leak as the old rocker cover was cracked and warped, I now need to replace my boost air inlet hoses as they have some cracks.

      R34 gtt rb25det neo timing belt kit

      By drifter17a · Posted

      I am being real ocd and do not want to make amy mistakes so appreciate all help provided. I am overly cautious so asking for opinion even if i know the answer   few questions,   1.re tensioner, should spring be greased lightly?    2.tensioner has two washers , one pressure washer and other has recessed/ seat. I am going to put the recessed one facing tensioner where edges are cut out and pressure washer on top   3. my car has custom triger kit sold few years ago by guy who initially built the engine. I moved the crank gear and it moved in and out easy, only way to remove belt is to slide the crankshaft gear forward which I did. I have seen these being very tough to move , anything to do with my woodruff key?   it has a crank sensor shown in purple which I assume reads from the 12 teeth position mounted to the crankcase gear   4. timing belt doesn’t have arrow stating front or back just a arrow which I think is direction of rotation . Do you agree?   5.i figured out why my crankcase cover was worn as there was no washer installed over the crankcase cover before the harmonic balancer was put in place. It is missing, anyone knows the part number? It looks like this https://justjap.com/products/genuine-nissan-crankshaft-timing-gear-rear-plate-washer-nissan-s13-ca18-a31-r32-rb20-r33-r34-c33-c34-c35-rb25?currency=USD   https://tinypic.host/image/IMG-4535.382Zy2 https://tinypic.host/image/IMG-4537.382dSz https://tinypic.host/image/IMG-4534.382q4U

      New fix for low tyre pressure from bmw

      CTIS (Central Tire Inflation System) has existed since the 80's. I'm looking into buying a Hummer H1 and they generally included it.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
