Yes a couple of threaded holes in the spacer is a good idea maybe with studs and thin spacers to form an air gap .

Yep, that's exactly what I did.

And before I fixed my spelling on last post I think every word was spelt wrong!

The 52T is now fitted and the front dump will be made in situ tomorrow morning .

Problems along the way were GCGs studs having the wrong threads and new breather and recirc pipes had to be made to suit Scottys induction pipe .

The 76 is well hidden under the std induction + airbox and comp outlet plumbing and if you look closely you can just see the "lobster tail" welds on the inlet pipe which is now VHT Caliper black . The nude turbine housing and spacer look different but the bulky turbo bag with bold red Garrett lettering will "hide" that . Thinking back that bag was probably a reasonably expensive mistake but time was not on our side and I couldn't afford to cook things around the hot side . Longer term I'll look into that ACL mat I reckon .

I'm looking forward to trying a 30 series and once everything is set up for these housings going a little bigger or smaller is much easier .

^ alternatively you could use the stock heat shield. Using some flat bar you "could" make a bracket that bolts up to the power steer reservoir and bolt it to the existing two holes on the shield.

Looks OEM..

I did something kinda similar, however had to chop off a massive chunk to clear the external gate and screamer pipe lol

Nothing wrong with the heat bag. Not sure the flash red advertising is exactly consistent with the "stealth" appearance objective thrown about?

Guessing the advertising cost a fair whack over the Plain Jane alternatives.

Either way you're about to step into a whole new engine performance league so I hope you're organised to tune as soon as possible.

Red lettering clashes will my hair . Will look into a moded heat shield because the more std camouflage the better .

I'll have it back in an hour or so and the road tuning I should be able to do myself .

If it's a toey thing I can go back to E70 because that's less likely to detonate than home brew E35 .

But yes tune needed and I prefer to do that when the EV14s go in , one tune then .

A .

I'll take some photos of my hacked up heat sheild this weekend.. it's not the nicest thing, because I have an external gate mounted on my rear housing but it will give you an idea

The "faceless men" LOL .

It happened - in 3.5" tube back to the cat and is painted black .

To be truthful aside from the spacer and bag it's difficult to tell it isn't standard , you have to look very closely between the factory pipes and airbox and then all you may notice is a couple of welds on the satin black inlet pipe . It's bag is down low enough that you can't see the lettering at all .

Sound wise it's very nearly the same as it was before around the burbs anyway . I have not leaned on it because all I was interested in doing was getting it home through the inevitable school zones and suicide hour traffic .

Naturally it doesn't boost at low revs and light throttle like the GTRS did and it needs fuel and timing changes because boost thresholds are different .

If I can get those shorty EV14s in with a modified Neo rail then the package is about as "std" looking as an R33 get to be IMO .

Pics later .

or just buy deatschwerks side feeds, stock rail, stock plugs, stock FPR.. winner winner!

Blerh. :P

^^ This.

Have you even tried the Neo rail for ease of fitment yet Disco? I want to start recommending it for my top feed Xspurt kits. Hurry up will you... :)

Have to let finances settle a bit but the Neo , Stag actually , rail I have already .

Injectors next and thinking along the lines of Xspurt 740s or ID 850 GMs , the shorty ones for least grief . The plan is to borrow both inlet manifold halves off SK and see what mods the rail mounting tags need to hold short EV14s down properly . If it works it should look factory enough to fool those who need to be .

Yeah what you said about the Denso side feeds , not bad on ethanol but if you want the factory like fuel control at low pulse widths then EV14s probably do it best .

Last GT30 update here because it's getting beyond fitting hardware . Went for a short run down the Princes Hwy to the Berg and back up the old road . Mixtures were surprisingly normal but needs work as it spools/loads up . It still feels typically RB25 torquey/flexible just without the early boost onset , depending on gear and load it shows positive pressure sometimes as low as 2300 revs but the transition is very smooth . Exhaust tone is if anything better than it was and interestingly inlet air temps are down ~ 5-6 degrees .

I sense less exhaust pressure and I think that shows as less throttle more often . In theory less throttle and increased charge density (lower IAT) should lead to better consumption .

GTRS and matching front/dump pipe for sale , cheers A .

You may recall I advised of a noticeable improvement in light load fuel consumption when I went up from GT2871 highflow to the GT3076.

It should take a few (2-3) more degrees advance at higher loads than the GTRS at similar points on the map. You've just made the engine a lot more comfortable and the tune will show you that.

Get the ranga shots up too.

Congrats on your mode to the world of "not strangling that poor RB25"! :) Sounds like you have already tasted the lovely sound and attitude of an RB25 that doesn't have asthma, I miss the smooth spool/rev of my old setup. Is yours the anti-surge housing, and does it make the silly noises the 56trims did?

Yes its a real one and no silly whistle sounds , no bell mouth insert either .

I'm having a few dramas with Vipec software ATM but that's more me than it . It wants to throw up multiple tables on the one screen where I prefer to use one at a time .

I wouldn't say it's the most boost happy thing but it's early days and I'm not on top of the boost control functions either .

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
