Turbo's For All

[gatty]

well as long as the flange is the right size i think we can deal with doing some braded line work

what kind of PSI are we talking about insode the oil/water lines?

also i don't know much about turbo's mate - when you say 0.82 A/R that means?

as long as it bolts on fine - i'm confident we can get the line work done

[The Dan]

Cool, I'll find out what I can

The water lines are only gonna be around 15-17 PSI.

The oil lines I think are only feed. I don't know if they are under pressure, if they are...it will be engine oil pressure.

between 20-60 PSI depending on revs.

'A/R is the ratio of the exhaust housing refering to the size and shape of the scroll that is cast into the housing. It determines how restrictive the housing will be, versus how quickly the turbine will spin up. A lower A/R ratio results in a more restrictive housing. This restriction speeds up the exhaust gasses and increases the amount that the gasses will expand. It's the speed and expansion of the gasses that causes the turbine to spin. So with a low A/R ratio, the turbine will spin up quicker, but as engine output and rpms increase, the restriction of the housing begins to build up too much back pressure on the engine, which reduces performance. A good rule of thumb for when there is too much back pressure is when the pressure in the exhaust manifold is more than half of the pressure in the cylinder. So basically, a larger A/R ratio will improve your engine's top end, while losing some mid range power and increasing turbo lag. A smaller A/R ratio will help the bottom and mid-range, but may effect the top end.'

[The Dan]

0.82 is a large size.

0.60 - 0.80 is usually good for the mid range stuff edging towards top end power. When they start going over 1 is when you get large amounts of lag. But you would compensate for this by using a Ball bearing turbo which helps to counter the lag effect. You can successfully eliminate extra lag by choosing the correct combination.

[gatty]

ok sounds good mate, find out and let me kow some prices - he wants more low end power as it is a auto so doesn't rev all that high unless in 2nd etc

[The Mafia]

has anyone recieved any turbos from this guys and have any comments about them?

Thanks. I'm looknig for a turbo to buy right now.

probably 450hp - 500hp, T3 Flange, with a .63ar Exhaust housing.

hi daniel, just wondering what a turbo off a HR31 silver top motor is, and how much 1 would cost??

[The Dan]

The Mafia: Will see what I can get.

85URK: I'll try to find out. Have you tried google yet?

[bigfella]

Hi Daniel and thanks for the turbo price, would recomend these turbos to all sua members as I have seen the quailty of the work.

I don't like your chances of being able to get anything rated to that hp with a 0.63A/R. I'll do my best.

Is there any reason for wanting the 0.63A/R?

You are really limited in your choices for the T3 flange also.

You would probably have to go with something like what I described above.

A T04 with a V1 compressor trim and the P turbine trim with a 0.82 A/R to achieve those hp ratings.

You might be able to play with a few options on the T3 housing to squeeze a little more out of it but I'll have to check with the supplier to make sure.

I'll see if they can do a 0.63A/R T3 flange on a turbo rated at 450hp. If not, have you considered going for something like a twin ball bearing GT25 or something that will be better suited?

You could also wait a couple of months as Garrett is bringing out some more designs in the T3 configuration. So then you would be able to get a GT25 440hp with a T3 flange. Now wouldn't that be nice.

No worries mate. Glad I could help. My other supplier has been really slack with those gaskets so I am going to try direct with ACL tomorrow hopefully. It's been two weeks and all they say is....oh, we haven't had time to ring. Bullcrap! I even reminded them twice. I might also try coventry or someone else like that. Anyway...I'll let you know how I go.

MY BAD!!!!! i ask in the forced induction section about this and the silver top rb20 motor only came out in the R32 gtst. doh! anyway, its for a mate he has a toyota sprinter with a 4agze turbo conversion and he needs a new turbo bcoz his one is blown, the turbo he has on it was off a rb20 silvertop but he told me they were out of a HR31 obviously he got mixed up. So i remembered this post so i though id try and get a price for him and see if hes keen. ok. thanx again for ya help with it. looking on google atm. will post again if i find out what type it is ok. i was told it could be a T25BB but not 100% sure. 4 bolt flange.

[pentae]

EliteForce: What is the name of the business?

I was recommended turbotorque by a friend of mine a couple of years ago.. Who took them over?

You can PM if you like.. if I intend on using them, I will go through you.

Definately not a BB. That would mean it is a ball bearing. The only skyline I think is the 34 which has the bb turbo. As for the silver top turbo, I have a blown one which I could have fixed for you. I would want $1100 with it fixed. It is a hi-flow and has supported me to roughly 215 RWKW. If you want a 360 degree thrust put in, then I think it will be slightly dearer but not much. Let me know if he is interested. When it is fixed, the only parts that won't be brand new will be the exhaust and compressor housings. The rest including wheels, shaft and cartridge will all be brand new.

[The Dan]

BTW, $1100 is what I have been quoted to fix it so sorry if it might seem expensive.

[gatty]

how much to fix a stock 33 turbo - without highflow etc etc - just to return to original working order (i think on of the seals has gone)

[discopotato03]

Are any details available about the new T3 flange options ? The aftermarket is crying out for things like a T3 flanged .86AR housing for the NS111 turbine (GT2530 , GT28RS etc) . We also badly need some integral gate GT30 and GT35 T3 flange housings .

Thanks A .

[The Dan]

Discopotato03: My supplier has told me a couple of months. But we all know how accurate that could be. Companies like Garrett can say 2 months but it will take them 3 or 4. All I can say is they are on their way and they aren't too far off now.

Gatty: I have been told that he will not just do the seals. All turbo's that come through him are to have a full service kit and balanced. The reason for this is quality of workmanship. He is the best I know and his work is proof of that. He said it will set you back around $550 as long as there is no other problems with turbines or housings.

Pentae: Sorry but that info is privileged. All I can say is that he is an authorised Garrett dealer. The turbos are all brand new. You won't be able to achieve cheaper prices without going through me. If you can get a cheaper price elsewhere, AND CAN PROOVE IT, then I will TRY to beat it.

The other thing I would like to note is that if you live on the Gold or sunshine coasts or in Brisbane/Ipswich or somewhere local to brisbane then I will deliver the turbo in person. And I can arrange a COD if you feel untrusting.

Got a quote tonight to do the braided lines.

Both water lines and the oil supply line including fittings, bolts and washers all custom made.....$100-$120

He shoots....he scores! I am really happy with the amount of service I have been getting from our local businesses. This guy finished work at 5 and drove out to my place to look at what I needed to do the job. Not many people are willing to do this these days.

Therefore, a big praise and plug goes out to Bayside Hose and Fittings. 07-3286 9354 They are located in Shore street Cleveland. 20 years in the industry.

Hey mate.

Just curious as to why you say the High Flow's are only 300hp when GCG and a few other places all quote there turbos at 450hp?

Just did a bit of a serch and a lot of people are getting 230-250rwkw's out of there high flows... Sydney Kid being the exception with 264kw

Also Does it matter if I get a R32 turbo highflowed instead of a R33 one (if cost is a huge difference between the two)?

as I will be buying a 2nd hand turbo and getting that done so I can bolt it on when I have all of my parts ready to go.

I am looking to upgrade the turbo in the next month or so. Just waiting on the bank balance to rise just a touch more.

Thanks mate

[s13viper]

How much horsepower/kilowatts do you want? 230rwkw

What are you using the car for? eg. Street/drag

When do you want boost roughly? coming on from 2200...full @ 4000

Do you want power early or late in the rev range? mid-late - i dont mind a Little lag if if will give a better top end hit...must last to redline

What Mods you engine has or is going to have including computers or exhaust etc.? zorst, intake, FMIC, fuelpump, injectors, probably a power fc, possibly cams

Obviously, what car? S13 with a RB20DET

Intercooled? and is it large, small, medium? medium at his stage....VR4 cooler - apprantly flows enough for 230rwkw

Still running AFM or upgraded or no longer there? stock Rb20 80mm AFM

Custom exhaust manifold or standard? (custom exhaust manifolds give you more options) stock manifold - as below....preffered stock but non stock if price is right

External wastegate or internal(limited to virtually 450hp - internal gate preferred but external if price is right

thx jason
