Hello from Australia; Here is my 290hp CA build, and the Bilet parts we made

[D_Stirls]

Hello all,My name is Dale. I have a Nissan 180sx (240sx) which I have been building up over the last few years. It's currently making 216rwkw (290hp) with a GT2871R 52T 0.64 turbo. I'm studying Civil Engineering and have developed same custom billet parts with my brother (Growly Custom Machining) for the CA's as there are same things that just aren't made for them and same things that aren't made any more.

My EB;

Here is my build section on NS.com;MY BUILD THREAD

Rather than list all the details again i'll just link the threads from NissanSilvia.com; these are some of the parts:

CA CAS bracket and Custom gears; http://www.nissansilvia.com/fo...8&hl=

CA Oil filter removal bracket; (similar to what is available for SR's) http://www.nissansilvia.com/fo...6&hl=

Tell me what you think.

Beautiful work! Welcome to the forum!

[BACARDI_DWB]

With that turbo how much boost are you running and when do you have full boost on it?

Thanks, i am very interested in that turbo, but wondering how its going to run on a CA18

[DALAZ_68]

that custom bracket is hella sick....but runnign it in L.A. id be p00pin bricks... sweet stuff though

[bentvalves]

AWSOME cas holder man, that things looks saweet.

[ragenasian]

I am surprised nobody has asked you to reproduce some of these parts yet.

Very nice stuff, wish somebody in my family could do that stuff.

[meminto]

Hey Dale, seems more and more people from the australian contingent are signining up ;P

The parts are being manufactured by his brothers company (growly)... I myself will be ordering some cosmetic gear shortly, they do some very nice work..

[D_Stirls]

As memento has said the parts are being sold but in Australia most CA owner are tight (since most of them are young, like <21) so not a lot has been sold but just enough to make it worth while. I did parts of the original designs for the parts and then (as with most things) there were some changes that Matt had to make when it came to machining them.

I went with that turbo because in the not to distant future (over our summer) I will be forging the bottom end and then I will be chasing bigger numbers, aiming for around the 350hp mark.As of full boost; it's around 4000 and at the moment it's 16 psi (small actuator won't allow more as it creep back when we try). with the cam gears we have set them up for response and manage to get 10-15kw more in the midrange all the way to the top end. The tuner said that's it's producing more torque now than most of the SR's he's tuned. It was interesting that with the bigger turbo, due to the lower boost at the given flow, when the butterflies opened at 3700rpm it droped the power out (you can see on the graphs). My tuner knew where the address was for the butterflies on the EPROM so we adjusted it to open later and it filled the hole (but i don;t have any graphs with the whole filled).

Here's a graph of my old T28 Vs' the GT2871 before the butterfly timing was adjusted, (and now with the butterfly hole fixed they basically mirror each other down low);

And here's a graph of when we were setting up the cam gears;

If you haven't read my NS.com Build section you won't know but i'm running a CA18DET exhaust cam on my intake side to give me the 248dur x 8.5mm spec's that you get with the CA16 cam.

Disreguard the green line.The red line is the base line.The dark blue line is with inlet cam 5 degrees retarded, which basically gives it the same spec's as a CA18DE exhaust camAnd the light blue line is with the previous inlet adjustment with the addition of the exhaust cam being 2 degrees advanced.So the dark blue line is what you would achieve if you slotted a CA18DE exhaust cam in with your factory gears.

[ca18detgabby]

god that is sexy

welcome

[hydra]

At what rpm does your power output peak with your present setup?So you found that the optimal setup for the cams was -5 for the intake and +2 for the exhaust? Great work btw...

[D_Stirls]

I see you started a topic on NS.com

As for full power with my set up i don't know off the top of my head because the graph is in km/h. But what i can say is that it;s the same a the T28BB that i had fitted before (if you look at the graph above comparing the two). This turbo is the bomb in the top end though it just keeps pulling to the red line where at the T28 would start too run out of puff. With the power that i'm making at the moment i'm no where near the potential of the turbo but since i have a standard bottom end i won't be pushing it much over 230rwkw (310rwhp) before i will be replacing the engine with my spare engine which i will be forging over the nex few months.If you were going to run a GT2871R and you weren't looking for over 245rwkw (328rwhp) then i would go for the 48trim version as it'll come on boost a bit earlier probably around (2-300rpm).

Looks great man! Keep up the good work. Any pics of the car it self? Suspension? Interior?

[D_Stirls]

If you click in the "My Build Thread" link in the first page it will take you to the build thread i have on NS.com there are some pictures of my car in there.

Here's the link again;http://www.nissansilvia.com/fo...93828

As for the interior it's pretty much standard, i had some cheap gauges in there which i have just taken out to fit some top quality ones. Here's the full list of mods for the car (which is in that build thread anyway).

How much to modify my timing cover like that, and turn it strictly into a CAS holder? I already have it semi-modified, it would just be taking it to the finish line in terms of machine work.

[niscort]

its actually a totally new replacement part, cnc'd from a billet i believe.

[bentvalves]

are you sure about that?

pretty sure its the remains of a factory cover.

Greg

[niscort]

are you sure about that?

Ill go out on a limb here, and say im 110% sure

[bentvalves]

ok, I'll do a backflip on a piece of floss then, and bank on it being a modified timing cover.

should check out about 1/2 down the page. some sweet parts listed there.

And there are a heap more parts that we have made and are in the process of making that he hasn't listed as he's been a bit slack with his web site. Basically it's still under construction.

Yep Gabby and Niscort are correct it's a complete new bracket made from billet Aluminium. The Modded Factory ones look tacky IMO and still retain the bolts that run behind the water pump pulley so it doesn't save you any time on the dyno when you are setting up the gears. These ones save you about 75% of your dyno time when changing gears because you can do a change in <3 minutes.

They are AU$180 as well.

Here's some picture if you still don't believe me;







The ones that are being made now are made in a dowed two piece design which looks exactly the same but saves on a bit of machine time and material costs.

[bentvalves]

dang wouldnt have believed you unless you posted those pics of it being machined.

Reason I say that is because I have one here, cut in half, and marked with a black sharpie that looks very similar to the countours you have there.

thing looks awsome btw.

[ca18detgabby]

I would love one of those CAS holders...... some of the cam gears too.

planning on swapping in a greddy timing belt real quick here as it is.

[bentvalves]

ca18det has taken my life over.

I say that with sincerity in my voice.

[r34 gtr]

I just want you to know that if you ever sell that sweet exhaust setup you've got, I will buy it immediately.

[D_Stirls]

The Exhaust was just a cheap Chinese one but I was lucky and it's made from decent material. The collector was a bit ****ty when it arrived but I spend a good 5 hours cleaning it up and port matching it to the turbo as well as refacing both the flanges. After I did all that I haven't had a problem with it over the last 2.5 years.Here's some more pic's

[DALAZ_68]

dude....sick ****....i cant to see what other prodcuts u have for the CA....i might become a frequest buyer once i save for all my upgrades...

any chance u guys coming up wiht a clear front cover...like the kind for the RB's

[D_Stirls]

We won't be making up and clear covers as just the machine time make moulds you would be looking at around $50,000 and there wouldn't be enough demand to recover that cost.

sad but true...ohh so true...i might just buy the backplate and cover to cheer me up...but what about those cam gears...so pretty

[D_Stirls]

The gears have changed slightly to allow us to use better quality cap head bolts instead of the button head bolt that i used with my gears. After adjusting mine a few times on the dyno the allan key started to strip but with the cap head bolts a lot more of the bolt engages the allen key and they don't strip.Here's the new design;

EDIT!! If you are after parts from Australia now is the time to get them with AU$1.00 = US$0.65. As an example, it makes these gears worth ~US$160 where as a month ago they would have been ~US$230.The Exchange rate as worked against me, I was going to do a rebuild over the Christmas break but i can't afford it now. It was going to cost me AU$2400 in parts now it's more like AU$3700; so it's not happening at this stage.

[r34 gtr]

So like, if I were to send you $160US right this very second you would send me a pair of those delicious cam gears? Because I have $160US right here.
