Turbo Help

[Stromulux]

Hey guys,

I recently had a little issue, the boost controller broke and i shot the beegeesus out of my turbo. I was running a well suited turbo but she's no more. Iv managed to source a turbo but im unsure how well it will suit the engine, it's a t3, maybe sourced from a vl turbo but i cant confirm this.

It's supposedly a T3, twin blade impellers.

My questions are, is this a viable option for a worked ca18? When could i expect this to come on boost and how would it behave? Is there a particular manifold i should be looking for?

I'd planned on a low mount manifold.

And I know I could jump on google and search manifolds etc but i'd love some advice from guys in the know.

Sorry for the vague questions, im not too versed in this just yet

If pictures would help just ask

I've asked else where but havnt got any answers so any help would be greatly appreciated, thanks in advance guys

So too many jerk on NS and you came here for answers ?

You need T28 with 5 bolt pattern to suit your car. T3x is not going to fit unless lots of modifications. Plus there a lot of T3x turbos around no one knows how it would perform on your car. Assume it is a VL T3 it should produce about 210rwkws on the CA with supporting mods.

If you want powerful turbo that bolt on to your CA18det we've made few and tested them all out at:

Or just overhaul your stock T25 to get back on the road.

Well given there are no real details on the new turbo, the old turbo, the motor, or anything else really.

So basically more detail if you ever hope to get an answer that is reasonable.

Aren't the Disco-potatoes all the rage for those type of motors?

Cheers for the advice mate,

However im not a member or user of ns, nor was i running a t25.

My current setup is a modified roller bearing t28, it worked really well coming on boost early and strong but i've always wondered how it was driving with a laggy turbo, as in when could i expect this to come on boost and how would it behave? Is there a particular manifold i should be looking for?

Hence the questions in the origional post.

Thanks for the url, im jumping in and checking it out now, i only ask about the t3 coz it was free... well a slab of coronas haha!

I dare say restoring my current one will be the cheapest option tho

Yeah sorry I didnt think the origional post out too well, its a ca18det, was running a roller bearing t28, hks cam and cam gears, injectors, ecu, head work,Tensioned valve springs, z32 afm etc... not setup for mind blowing power but good fun all the same.

Here's a pic of the new turbo, 6 bolt rear.

If you need more pics please ask

So what's stopping you exactly from putting a similar turbo back on?

Sounds like that is what was going quite well for you.

That turbo (t3 flange) will require a bit of dicking around with new manifold, lines, piping, dump etc etc.

Overall you might not even see much more overall power as just a pic of the turbo really doesn't tell us much... could be laggy and unresponsive... who knows!

IMO go back with what you had would be the first and cheapest option, fastest/easiest as well i might add.

[PROXIMITY]

Not sure thats a Vl turbo

And as others have said, the money you have saved by getting this turbo cheap you will spend on custom lines, flanges,zorst and inlet all to suit.

Scan the forums for cheap s15 turbo or s14 that way be a strate bolt on and run similiar to what you had, and should cost no more than 3-400 =)

[Wheezy]

Tiny then, will make 180rwkw max on one of those if its stock and be laggy.

The Jap spec S15 turbo's are nice and responsive, that would be my option of choice if I didn't want to spent a lot of $

I felt like going something a little different but it's starting to look like thats not the best option.

Thanks for the advice everyone.

Are you sure R32 turbo, I was under the impression they were a ceramic wheeld T28 unit?

[GTScotT]

get another T28 mate

CAs and T28s are a great combo, as stated above they have also been known to rock on with Disco's. Personally I have had extensive experience with a stock bottom ended CA that had a T28 and then upgraded to a disco. Ran at 1.3 bar on the disco and made the 200rwkw range with REALLY good response. That was years ago, car is now a drift cop and original motor/turbo combo are still going today 200,000+ ks by now id say (last saw it in 06 with 180 lol).

Im sure NS has tried to SR bash you just because your turbo blew LOL.. ull get that -_-.

also, the disco gives a little more top end than the regular T28, but midrange on the OEM type T28s is great, still with 'similar' peak figures.

Get a T28 from an S14 or S15 and ur laughing GL

Great stuff thanks GTScotT!

I know im going to sound like a goose but what's the dif between a t28 and a disco? Different wheel? I was under the impression they were the same thing.

I do get a little trash talk for the ca18 from sr owners but I wanted to go something a little different, it's too easy to make power in the sr. I actually dont use ns tho, not a fan haha

[GTScotT]

lol SNSW or NS all the same when it comes to CA bashing.

the turbo usually reffered to as the T28 is the OEM turbo found in S14s and S15s. personally i dont believe the hype behind the JDM S15 ballbearing turbo so if ur not a fanboy dont bother.

a disco aka discopotato has a a couple of milimeters more on both compressor and turbine wheels and are in slightly bigger trims. basically they take a mild amount more to spin up and flow abit more up top.

"T28"

Cheapest option would be to find urself a used T28 out of an S14, thats the way id go anyhow.

Being different is one thing mate... but spending a whole lotta cash for the same end result is another

Sounds like you are going with what you have though...

The GT25 and GT28 BB turbo story .

The GT25 based turbos use a 53mm 11 bladed turbine in 62 trim .

The GT28 based turbos use a 53.8mm 9 bladed turbine in 62 or 76 trim .

The GT25 BB turbos mentioned in this instance can have 54.3mm or 60.1mm diameter compressor wheels , basically GT2554R or GT2560R . The former has a 0.80 A/R T25 compressor housing where the latter uses a 0.60 A/R Nissan style T04 compressor housing .

From memory the GT2554R is a bolt on for CA18DET's and the GT2560R original equipment on some SR20DET's .

The part number 466541-4 (GT2560R) was mentioned above , that is the JDM S15 manual trans version of that turbo . The 466541-1 and -4 only differ in that the -4 gets the Ni Resist turbine housing and Inconel turbine , higher temp capable materials than the -1 version . -4 also gets that deflector vane in the back of the turbine housing as well .

As I said the GT28 based dryers get 53.8mm turbines , the GT2854R has the 9 bladed 62T turbine while the Disco turbos get the 76 trim one .

There are a few variations in the GT2860R family with the DP turbo being the highest performance variant . I know people want to argue the point in SR20 circles but these were intended to have the larger of the two sizes , 0.86 A/R , turbine housings on them though some prefer the 0.64 A/R one .

There is also a HKS GT2860R variant for SR/CA known as the GTSS , not the same as the RB26 GTSS .

It has the GT28 76T turbine and the cold side from the GT2560R .

There is also a Garrett variant that looks very similar spec wise to the DP turbo , its compressor wheel has exducer tips not quite as high as the DP's and has a different cartridge no .

If buying new I'd strongly consider the GT2554R or GT2854R , responsive things on 1800 turbo 16v engines and I think they pretty much bolt up .

Recently I've been speaking to people in the US turbocharging MX5's (Mazda BP18 engines) and they quite like the GT2554R's . Some use GT2560R's and while they make more top end they come on later as well .

The GT2854R is interesting in that it gets the GT28 62T 9 bladed turbine so makes a little more top end than a GT2554R .

The GT2854R isn't normally imported into Australia because it costs a bit more and isn't much larger internally .

The cost issue is mainly due to them having the hi temp capable turbine and housing material , the good manual S15 turbine housing with that vane in the back . If you want one they can be brought in , just not usually on the shelf here .

Personally I look at the GT2854R as a scaled down DP turbo , higher flowing and more efficient turbine than the GT2554R so possible to push a bit more timing in and gain overall .

I've never had CA18DET's and I'm not sure if the Disco or GT2860RS turbo would be a little big for street/drift use .

Just so you know these have the GT28 76T turbine and a high tip height 60.1 mm 62T compressor wheel normally in a truck style T04B comp housing .

I've had SR20DET people say they didn't like the 0.86 turbine housing DP turbo combination claiming it was too "laggy" . I have one I used years ago on an FJ20 and really liked it , a bit lazy until you learn to throw in extra light load/low boost advance which makes them really come alive .

Go to turbobygarrett and look at the GT25 and GT28 turbo specs before you make your decision .

Cheers A .

PS , the turbo in that pic is not from an RB30ET . The compressor inducer is too small and the housing is too I reckon .

At home I have a VL's compressor and housing kicking about and they don't look like that .

Even if it was it would be a laggy dinosaur on a CA18DET . The Early low CR FJ20's and all RB30 turbos got a 0.63 A/R turbine housing , lazy on the FJ and possibly not big enough for a 3L engine .

Both engines were rated at ~ 150 kw with 6-7 pounds of boost so you don't want these dinosaurs . They wont bolt to a CA/SR and wouldn't be nice if they did .

Drink the slab yourself , cheers A .

Hey Strom'

I've got a CA18 and running a GT2871R ATM.

As other have said the disco potato would be the turbo of choice up to ~230rwkw and above that you'll be looking at a GT2871R.

People have started to go away from the GT2860RS (DiscoPotato) in favour of the GT2871R in recent years but the having said that the T2 GT3071R seems to becoming the flavour of the month now. People always want more power i guess.

As for a budget turbo though you should be able to pick up a T28 BB (S15 T28/ GT28R/ GT2560R) for around the $400 mark and that will get you well into the 190 mark and since your running cams you should break the 200 mark.

My CA is making 217kw and is basically internally standard apart from playing with the cams (they are still factory cams though but just running 2x Exhaust cams i.e. 248 x 8.5).
