You would probably find that you would get better results from the precision than the op with the 2.5 and cams.
Would expect a lot closer to 500bhp with more torque and coming in earlier.
Whether its worth the hassle/cost of the swap is another matter though.
I'm currently on the lookout for a new turbo but my set up is 2.1with standard v5 sti heads so looking at maybe sc42+ or maybe go all out with rotated gtx30.
I think maybe the precision will be too laggy for me on 2.1 with no avcs or cams.

Was gonna buy this precision prior to being for sale, but may have been to different to drive on/off throttle compared to the sc42 so decided on another sc42 for now as you just cant beat it for drivability.
You could probably make 440 on the sc42 lol.

But just to add, the op paid £850 loooool. Id say charge upto 1k and no more as like i said they are £1500 new plus fitting kit.

what does the sc42 cost ? how many rupees ?

A lot! Last time I checked was just over £1700
A 2.5 would benefit sc46 as that's what they designed for

Nezscooby

It’s £1740

A few of us have been saying it for years

Can anyone guess what we've been saying?

subarustel

The forums gone to s#=t. Its been like this for years

Thats what we've been saying

Subaru breakers selling chit parts. Tuners giving you the wrong advise depending what they want to sell you that month, or underselling you a turbo, knowing you'll buy another to make those magic numbers. Everyone else trying to be a keyboard warrior

Nez, i text you the flow rates and efficiency ranges of alot of turbos. You were advised (as were so many others) a 52.5lb turbo would make 500bhp on vpower, when they should know better. I know what it takes to make the numbers. Alot more than a 52.5lb turbo Even you've done the math.

Over 10 years ago we tested the aps sr series turbo. That wouldnt make over 500bhp on a 2.0 on vpower. The precision wont make it either. The aps was similar spec to a sc50 turbo. 55lbs flow

Everyone else should stick to a 71hta or go rotated. Cant afford to go rotated, then the precision is a good turbo.

As for sumo power selling the precision for £1500, its £1500+vat. Even they jumped on the bandwagon when this turbo started getting popular. They raised their price by £300

bustaMOVEs

iTrader: (31)

No it wasn't, sumo were 1 of the first to start selling it, and it was 1500 delivered to your door, I won't say something if it's not factual, this turbo on here came from there at that exact price, as said I know exactly where it came from, only thing on top was a fitting kit which he bought from aet.
Tbh I don't think sumo list it any more but I bet if you called Ross he would get you one probably a bit cheaper by now as they seem to have a better relationship with the Americans so will get a good deal on them and pass on to us without a silly markup like some still are.

bustaMOVEs

And the precision HAS made 500+ on certain cars, all needs top spec including fully built heads and cams etc, rcms car as an example.
You need to go hide back in your cave as it seems you are a bit rusty.

subarustel

Busta, you need to read what i wrote properly

Sumo "use to" charge £1500 delivered. Not now. Now they are 1800£

You mention ross. Ive known ross for well over 10 years. He actually use to meet me personally for my parts, though not sure what that has to do with anything. Rob from sumo deals with all the sales for this turbo on a subaru. You'd be lucky to get £100 off it

Yes the precision is 500+ bhp. Not on vpower though. If you understand how a turbo works, and how flow ratings are calculated vs fuel used, you would be a wiser man. 52.5lbs equals 525bhp. It even says this on precision website. maxing the turbo out with the right fuel and supporting mods.

Nezscooby has a 2.1 built engine and supporting mods. He is maxing out the turbo. He was mapped by one of the best mappers. He made more than 500 but not on vpower.


And what he wants to sell the turbo for is entirely his choice. He wants to make a few quid, thats up to him. I dont see anyone complaining to tuners when they buy a turbo for xxx amount and add 40% profit margin on it.

Anyone else have something to add here?

johno01

if Nezscooby wants to ask 1400 for his third hand turbo with Unknown mileage then good luck...what Nezscooby failed to include in the information he provided regarding the turbo was in fact its done alot more than his claimed "1000" miles and it's a 3rd hand turbo...he said that's what previous owner of turbo told him,well he had his pants pulled down and he should live and learn...also Ive never had any issues with a "specialist" selling me a used turbo as Ive never bought a used turbo.

bustaMOVEs

You never put 'used to' hence why I didn't get it, you put they have jumped on the bandwagon and upped their price like the rest, now I don't know why they would do that tbh as ultimately that will lower their sale count as they have a big relationship with the American tuners, hence the stuff they sell and Ross told me himself that they get a reasonable deal as they spend a LOT of money with them. Naturally if you put a lot of money towards somewhere you naturally get looked after. (Have you actually enqired recently on that price? And if so then they may have decided to up it, but that doesn't make sense to lower your sale count).
And yes that precision HAS made over 500 on vpower, again rcm's car to prove, that's been built from ground up, so yes it can if all the spec is to a high standard, I'm pretty confident 'fingers crossed' that with 278-282 cams it will get there.
I don't follow this detailed info what all this lbs is or what it's supposed to do etc, I've seen facts myself on vpower. I agree most will bang this turbo on expecting to get 500+ and in fact most will actually make around 470-490hp which I've seen regularly. It's obviously missing some key components to make that extra on top end. You've obviously been in the game for long enough so I shouldn't even have to explain to you, hence 'rusty'

ZANY

Love you 2 bro

subarustel

I enquired with rob @ sumo around xmas time. £1500+ vat, minus i think it was 5% discount (cant remember exactly as it never meant anything to me. I actually pm'd you around that time and asked where you'd seen the turbo for £1500 delivered if you remember. Id probably get a better deal if I asked ross personally, but i know how busy he is. I prefer not to bother him for the sake of £100 or £150

With regards to the rcm car. Id like olly or matt (they did all the engine work on my car by the way) to confirm there wasnt a splash of meth in the tank. I personally know for a fact that a 52.5lb turbo won't make 500bhp on vpower. On top of what i know about turbos, which nezscooby im sure can confirm, you need a larger compressor wheel at the very least to make 500bhp on a 2.0 engine using vpower. Another thing to mention, im sure theres a few threads on the forum about the precision turbo. None of the threads ive read nor has anyone apart from the rcm car made 500bhp on a 2.0 using vpower. Did they sprinkle some angel dust on the said turbo before the dyno run? Or did they use a slightly bugger compressor inducer to mate up to the 76 exducer found on the precision? We will never know.

to back up what im saying. The Owens 71hta is also well tested around here. Flow rates around 51lbs per minute. I know 2 people with this turbo. Both make the same power within 1bhp of each other. Vpower = 453bhp. On meth maxing out around 500-507bhp. The precision flows 1.5lbs more. 1.5lbs doesnt equal 50bhp. It equals 10-15 bhp.

If anyone wants to discuss turbo's, their flow rates, or sizes, feel free to send me a pm with your contact number, and Ill call you back

subarustel

The precision is there. Just above the fp 71hta which is where i put the owens 71hta. There are mistakes on the list, but they are irrelevant to this discussion. Flow rate is the last column of numbers.

Maybe you did, as I do remember a pm regarding it, don't recall who it was though lol, I get a few odd questions lol.
It's a shame that then if that's the case as I thought they were good at getting prices down, it maybe worth a shout to Ross as apparently he deals with the yanks on the stock I think and it was him who gave me price and said he will chuck delivery in with that, maybe rob just quoted the going rate without double checking with Ross to look after us. Either way, I agree tuners do like to milk it a bit from us to make a nice mark up, but I find it all depends on the item you want and if you know who to go to for it then you get a nice price, just like the cosworth cams I bought without the logo stamp on them to bump up the price lol.

I had this discussion before regarding PT making 500 as I was like you, and mad hammer (Clive) which is know to know his onions and knows someone else who runs over 500 on that and assures me rcm's test car is actually vpower only but built well with Gucci headwork so I can only take his word for it which I've no reason to disbelieve him.
I actually think it takes a lot to make it work but I believe it can work with Gucci heads and a good built bottom end that will go high rpm.
I'm building my engine for high rpm also so hopefully if I bolt a big turbo on then I'll see the benefits and also keep my engine safe from hard driving as it will only be fettled with what I'm going to push through it for now.
I have the grap somewhere of the rcm car and there's a thread somewhere of me cussing the PT to regards it 50hp goal

Have a read through this thread where I said the same, but Clive had to put me right.
Very rarely cars a built for more increases in power so with certain Gucci parts the PT has proved to exceed your flow rate

subarustel

We are going into overtime. Nez made very similar power to the graph with a high ratio of meth. Im sure we all know the team at engine tuner know how to map. One of There own cars runs:use to run a 55lbs turbo at 550bhp (im guessing)on meth/race fuel.

I have been reading graphs for years. I use to read power or torque at rpm to get an idea of where the turbo hits what boost. Where the actuator opens, and where power starts to fall. How long the torque is held for through the rpm range.

What i never really read into until the last few years is the smoothness of the graph. I have noticed that on a meth map, unless the mapper goes through quite a few points at certain rpm, which takes alot of time, the graph will never be as smooth as a vpower map, that a mapper doesnt have to spend more than 20 mins on. I did say "unless they spend alot of time"

Also, unless time is spent perfecting the map more so on meth, you get flat spots. Or dips in the graph. The average driver would never notice. I do. Notice anything on this graph?

I am too tired to talk about how long in the rev range the torque holds on for. That is another thing i have taken alot of time evaluating. If it really interests you, do some research. This equates to the type of fuel used, though other things play a part, fuel is a big factor

With regards to clive, i know who he is and have respect for him. But unless he built the turbo, or ran the fuel tank empty and then filled up with vpower, gave them an engine that hes opened up, he cant be sure

Sigh! Your talking about nez's car that is on 'stock heads'! That's not even a comparison.
You know what, ask martyn about rcm's car as he even commented that all his ducks were in a row. You are just too fixated and denial on this flow business, but I've tried to tell you that some well respected people have proven me wrong on the subject, I'm done also as unlike myself who chose to understand and take it, you're not.
Have a nice evening

subarustel

Im not in denial at all. I too have seen 3 or 4 cars exceed the flow limits of a turbo. For us average subaru owners, me for sure dont have upwards of £2.5 to spend on heads and cams. Plus fitting and headgaskets, and then map. Ive also seen people spin a turbo well past the recommended manufacturers rpm to give more flow of course on the right fuel with the right mods

1 example is a friend of mine who has a subaru. Over 700 bhp on a gt35r. He is running about 15% more than the said flow. Built as you said from ground up. Race fuel. He is happy to spin the turbo past its rpm to flow rate. Also happy to replace the turbo every 10k miles. I, myself would expect a turbo to last 60-100k miles

Just by that post, I really don't know why we've had this long winded post then. Some cars have exceeded manufacturers recommendations on pump fuel and that's it really no? That was what we was talking about no? Even the PT as we've been discussing.
I'm happy you've acknowledged but what a pointless waste of time for you to understand what I was trying to say.
Of course a turbo could last 1 mile or 100.000 miles, it's the modding game, nothing is garanteed. Keep it on low boost and stop chasing numbers would be a good shout for longlivety

Nezscooby

I think with ported heads and performance cams the turbo can break the 500 mark and Busta is right I am with standard heads and cams at 470 bhp but I really don't know how much bhp would a ported heads and performance cams would give....

Thank you, can you please tell your friend also.
Look at rcm's car, just think how much money alone is in their heads, they will have some mad parts in there, not to mention what the compression ratio is and if they are using longer rods, for them to make 528 on pump fuel it show the turbo IS capable, (with right mods, which most of us haven't got the money to build it similar)
Would love to get hold of a actual spec list of their car
