Fark man, that is a great setup but an expensive way to make 250-270rwkws, (not saying its a bad thing) Just grab a 6boost manifold for $800, a 3071 for $1800 and the fraction of a second (tenth?) you will be slower around a track just means you get more track time then others :) Twin gates! Fark me, i understand the gain etc, but a 3071 is pretty punchy to start with.

Actually that setup makes 26psi by 4000rpm and 290rwks at 22 psi at around 7700 rpm :)

Yeh, i recognised the pics from your build up thread and know its a great setup. But to get that good a result it costs money :) LOL, i am a tight ass and live with 19psi by 4300rpm and 260rwkws with 19psi with a pretty doughy power delivery. I have a shits and giggle build all worked out for an RB20 that i think would match it or get similar results, only i need a house with a garage first

Yes you gotta pay to play.

Could be done cheaper tho' ....get Kyle (6Boost) to make up a twin scroll mani and order the 3071 or 3076 turbo and twinscroll housing from Full-Race or ATP in the US or GCG here in Oz and keep stock intake......or if using a highport SR then go the Greddy intake. Tial gates can be had from anywhere. All other supporting mods are pretty much going to be the same regardless of the turbo setup.

As to the worthiness of the twin gates over the single gate version...Geoff Raicer (Full-Race) suggests its worth around 250rpm in which case you may be tempted to upsize to the 3076 over the 3071 for a cooler charge and bit more hp.

The beauty of the twin scroll setup is not so much peak hp (I think single scroll turbos actually produce higher peak hp) but a broader power band and rev range which is perfect for street and circuit duties ......and also the ability to respool the turbo in on/off throttle applications faster than a single scroll setup and because of this ability it actually feels like a big N/A engine which IMO is again perfect for street and circuit duties.

Regarding my setup........26 psi by 4000rpm (although it hauling by 3500rpm) and peak hp at 7700 and power doesn't taper off much at 8,000 (so its carrying torque to the red line) - so it has more or less a 4000rpm rev range which is not bad for a turbo motor.

I've never had much to do with the RB20 but they seem to lack a bit of mid-range torque based on the ones I've come accross at Barbagello.....then again so did my brothers LS2 powered commodore - too slow out of the corners.

But sounds like you've got it all worked out tho' - good luck with it.

PS - my brother ended fitting an APS twin turbo kit to the LS2 to give it some grunt out of the corners. We've never been back out to the circuit since our respective mods but should be interesting when we do.

See, I don't actually think it would work out much cheaper doing it here Ian. My (rough) calculations are as follows:

6 Boost Manifold - $1000 - $1100 or thereabouts (not sure on the twin scroll)

3071/3076 - $2000

Tial gate - $4-500

We're already at around $3500 and don't have a dump pipe or the second wastegate. I actually think the full kit is decent in price in comparison if you could get it for a bit of $4k when the exchange rate improves a touch.

That's what's made me think of it, apart from your build, is the price compared to a full kit here. There's really not much in it and you get the best setup going around

Hi Dane,

There would also be GST and import duties to factor into the original cost of the kit....unless you bought it in bit by bit....hint hint.

If you like I can pull out my records and let you know the all up actual cost of mine including import duties?

You could then get a quote from Kyle for the manifold and I know he can also supply turbos and gates - so you could get a comparative kit price and do the maths.

Cheers,

Ian

That would be great if you wouldn't mind Ian. I forgot about the pesky GST and import taxes... haven't had to fork out for those for imported goods in a while!

With those tossed in you may be right mate, will be good to get a comparative cost.

Cheers,

Dane

SAU NSW Track Day at Oran Park is now open for entries as well. http://www.skylinesaustralia.com/forums/Sa...-T-t286613.html

This is genuinely one of the last chances so don't miss out....the bulldozers are (literally) waiting at the gates for 1/1/10

Thanks a lot for the Ian, very much appreciated mate.

It seems that perhaps their pricing may have changed slightly, or maybe I'm missing something??

From what I'm entering into the site, it comes up with this:

3076

Manifold

Manifold HPC coating

Downpipe

Tial Wastegate (unsure if this is just for one, which I'm assuming it is as the price doesn't change between twin and single 'gate options)

= $3474 + $238 shipping US

But it's the extra 1k from the Aus government that is the killer...

Might have to confirm with Full Race on pricing if I decide to go that way.

They may have adjusted their pricing given the economic downturn especially in the US.

Actually best to confirm with Aaron Teague at Full-Race as he handles all the sales side of things - email [email protected]

Thanks, shall do.

It also says something about them having a summer sale on the site, so it may be an automatically adjusted price. I'll ask Aaron though, just need the dollar to continue this sweet rise :thumbsup:

Here is the head the head you sold me baron

today was fairly productive, made up some oil restrictors, put the head on etc

sweet ;) It's the most fun I've had giving you head..... :woot:

I wish I could get complete heads as cheap as I sold that one now! Your head was lovingly removed and checked at prime garage so it should be good, in fact Tono at prime was going to buy it when he pulled it down, but I wanted it so we gave him the block/crank/rods/pistons out of that engine as a christmas present instead and kept the head!

it will be a pretty sweet donk when it's done. and I would hazard a guess all up not too pricey either since I know what the head cost ya! hehe.

Here's another update of my 3.1lt big little engine prototype. Ive completed the final assembly of the bottom end over the weekend.

The block is a partially grout filled RB26 05u block, modified RB30 crank(drilled+screwed, balanced, modifed rod journels and slotted for oil squirters), pauter billet rods with 19mm bearings, custom wiseco's with 22mm gudgens and non-interference valve pockets, acl bearings, and dartron sleeves.

Here are a few pics.

Cheers,

Ian

looking good. I think I'm entitled to a drive after it's done. it was my baby after all. going by this thread there is a little beer baron in everyone... :woot:

Sorry Ian, another question... Do you know what section on NS the car you're referring to in this post is located: http://www.skylinesaustralia.com/forums/in...t&p=4594093

I can't seem to locate it.

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
