It does look pretty hardcore. If they tone down the styling a tad just like they did with the new GTR, it'd be a winner for sure. I like the side and back but the bullnose is a little over the top. Kinda reminds me of the 34 GTR. The Cd musn't be the best either.

Nice power with some nice lag! I wonder why HKS would offer this for an SR20. Comes on boost at redline lol.

PP available here? Thats pretty cool. How much was it Cubes? Apparently its basestock is similar to PAO in performance but not as expensive to make. PS Remember $49 for D1 at Motrex. Unbeatable!

I do know a guy that you can buy Delvac from in Melbourne. He bought it in a 20L barrel and wanted to sell a few liters...

Well theres no problem changing out the oil sooner besides a lighter wallet. But half one of a synthetics's big advantages is because they have the capability of handling longer oil intervals than mineral oils. Take a look in USA for example, they market M1 "EP" which is guaranteed for 15,000 *miles*. So I believe 10,000km is suitable for most engines using a good quality synthetic, providing they are in good condition, don't run excessively rich or have heaps of blow by or don't see track use. Looking at hundreds of posted oil analysis's over the few past years has provided me with this conclusion. Remember just by looking at the oil doesn't really tell you anything. If you want to drain out $90 every 6 months by all means.. just seems like a bit of a waste thats all. T04GTR, I'm very sure oil filters do not use the same media. Sure they are cellulose but its like saying all engine oils are the same because they are liquids. There are definitely the better and worse ones out there. Also I don't think EDGE 5W30 is TXT softec because it does not have all of Softec's OEM approvals eg BMW-LL 01... unless you can find some data to prove otherwise but yeah.

Nothing will "happen" as such. You may notice better fuel economy/engine responsiveness or less noise on cold starts... *depending* on what you've been using in the past. It should also easily go the distance. Ie 10,000km oil changes, providing you don't do track days etc.

aquariuz6, yes IMO their 0W40 is the best out of the EDGE range and I would recommend it. vbdotnet, well being Repco, what can I say. Will do the job for at least 5,000km intervals. I'd give the EDGE 5W30 a go on your next change. Devlac is too hard to find (although its easy for me) and 300V is a bit overkill for your R33 with the usual mods.

Can I tag along? I wouldn't mind a ride either. Im errr... looking for a bigger turbo too!

Castrol EDGE is just rebranded Formula R. Not a single word was changed in the specifications in the PDS's from what I've gathered. But how knows, they might be different. But yes being synthetics (well API Group 3 base anyway), they are much better suited to our cars than a semi or mineral oil. I still would say they are not as good as Mobil 1, judging by their specifications. Only their 0W40 would be the exception which would be comparable (being API Group 4, ie PAO). I've trialed EDGE 5W30 in my car as 'flush'.. seems to be working well so far.

Thanks SK for the informative replies as always. I totally forgot about diagonal weight balancing which is more important than front to back (which I was implying with the FWD layout).

Half the time I find is that the increase in power comes from running higher boost than before, just like with exhausts.

Yep no problem to use that oil. But as always, you can do better Castrol EDGE 5W30 or their 0W40, or Mobil 1 0W40 or 10W30 would be a little more appropriate for a street driven Skyline.

Didn't realise they were so popular! Good feedback thread for sure.

So what about cars with non adjustable height? Nothing much can be done eh? And what about FWDs? Would their ass be on the ground and nose up in the air?

Got an OS Giken Twin. Not bad, but it can stall on you sometimes if you don't give it enough revs. Even after 6 months of having it, I'll stall it at least once a week still. I reckon its the super lightweight flywheel that causes it rather than it being too 'bitey'. Then again I have an SR20 so its probably a different case on the RB2x

Ah yes forgot about it not being water cooled. I should know, I have a T518z myself lol.

It always seemed to me that if your intake pipe was sucking itself shut, you got one restrictive air filter

I wonder how fast that car woulda done it if it did his gear changes right (or if it didnt have that funny 'flat spot')

Its "too wide" for my tastes but 10 points for having a go!

^^ Ah yes well I never thought of the RB26 but as you say, it'd still work better than the stock location with an atmo BOV. Come to think of it there may be better improvements with fuel economy too? I notice that when I back off from a medium load, the AFM continues to read air for another 500ms or so and thus the PowerFC is still dumping in fuel instead of going to decel injector cut...even though the TB is shut (and no, the atmo BOV is not venting). I attributed this to the volume of the FMIC and the fact that the turbo is pulling some air etc. I guess with the AFM after the FMIC, we could say that due to the more precise metering of the air, better fuel economy may result?

280rwkw, nice job. That TD06 is giving you good results for sure. I take it its externally gated?

Damn I'd love it if a Blitz ID3 could gimme that kinda power. Sorry.. had to say it haha.

Should be alright, what are your targets? Low 200rwkw shouldn't be out of the question. You can get a T3-T2 flange to allow it to bolt on. You'll need new water/oil lines as well as a new dump pipe. Not sure if the housings will need to be rotated though. After all that screwing around, a high flow seems a much better option.

Well the air between the TB and BOV is still insignificant at 5" of piping as in my theory. Its certianly faaaarrr less than the capacity of FMIC and its associated piping if the AFM in its factory position which causes it to run rich. Also in reference to your second point, the TB is shut. No air is going to pass through the AFM when the BOV vents. I mean how would it? Its a dead end. I guess 3lit3 32's experience reinforces my theory. I also noted that my car ran rich when backing off on full boost, even with a recirculating BOV. I'm real tempted to try this on my car. But I'm just to pansy to hacksaw the filter flange of my Z32 AFM lol.

Well my theory is a bit different to you guys about the BOV. Lets say the AFM is 3" from the throttle body. The BOV is about 5" away from the TB, ie placed just before the AFM. On full boost we close the TB, and then we get a slight about of reversion which the AFM reads. But the AFM is is pretty close to the TB so we could say 3" x 3" of piping is not really a significant volume which contradicts SK's theory somewhat. So.. the pressurised air between the turbo and BOV (ie FMIC etc) is all vented out through the BOV. But the key is that the AFM had never measured the vented air in the first place, so thus it won't go overrich. Does my theory make sense?
